Musing

Here’s a few shots from December’s shoot at the Cottage Studio http://www.thecottagestudio.co.uk/  with Elle Beth http://www.ellebethmodel.com/   .Over the past couple of weeks, I’ve been commissioned by other models elsewhere in the UK, seeking to expand their port-folio in 2018.

Some follow the fine art narrative, others seeking something more visually dramatic, or indeed, provocative in tone. I’m happy doing either, considering each on their own merit. Nothing (legal) is off limits, save for gratuitously pornographic.

Salty and slippery stuff licked the first application of nasty lube clean after 300miles, so I topped it up and resumed testing. Cleanliness is better than I was expecting, although predictably, my chain’s outer plates were sporting a gungy beard. Less problematic on a fixed/hub/single speed transmission. However, I’d be wiping these weekly on a derailleur geared build to avert component consumption.

Those 38mm Soma are delivering precisely what I was expecting from a tyre marketed as for road and commuting duties. “Gravel” has been a big thing for a while and for me, has captured the original spirit of mountain biking. Vernier in hand, they actually came closer to 35mm, which didn’t surprise me, having learned they’re made for Soma by Panaracer. However, I was pleasantly surprised to discover they’re also available in more traditional 23 and 28mm road sections too.

The Shikoro takes its name from the neck armour used by Samori warriors, inferring a tough, puncture repelling casing. The polyamide puncture repelling bead runs edge to edge, rather than simply covering the centre strip. Bodes well, given the roads can be decidedly unforgiving this time of year

Supple, leach like cornering prowess and a magic carpet ride. Unlike other vehicles, bicycle tyres needn’t have any tread. The Shikoro is basically a low-profile gravel pattern, which coupled with the puncture repelling qualities, suggest a tyre best suited to hard-pack/dry gravel/cross meets, interspersed with longer sections of asphalt.

A decent quality slick (not to be confused with bald) tyre, run at the correct pressures is arguably optimal for tarmac duties. Thus far, traversing the same roads littered with thorns and similar hedge clippings, hasn’t induced any nicks, or similar damage to the casings, let alone punctures.

I was surprised by the operating pressures, which range from 35-90psi, closer to that of a tubeless system. In theory at least, this should cover the entire zodiac of riding conditionals. Minimal rolling resistance on virgin asphalt, optimal traction on loose, icy surfaces.

Obviously, rider (and luggage) weight also play a part.  Current trends suggest an extra 1% pressure for every extra kilo. Working on this basis, 70-75psi should prove optimal. We’ll see. So far, run at their maximum, they don’t feel remotely harsh, although by my reckoning, big tyres should be compliant and comfortable at the upper end of their operating pressures.

The sudden resumption of wintry weather proved an ideal opportunity to see just how well Schwalbe Marathon 365 perform in the ice. Reassuringly well, it appears. Sure, spikes add another level of confidence but run at 65psi, their wide profiles hugged the tarmac, 15-17mph through the slushier stuff with no apparent skittishness.

In this context, their additional girth isn’t a hindrance. Admittedly, the machine’s more upright positioning also helps keep things on track.

This recent chill snap has also made me grateful for these Lake booties, which are far more convenient than overshoes when it comes to beating the brrr factor. These are MTB versions, which also provide scope for more adventurous outings sans asphalt. Not your bag but wanting a rugged set of boots that you can also do a day’s work in? Take a look at Steve Dyster’s test of these Chrome Storm 415 https://www.sevendaycyclist.com/chrome-storm-415-cycling-work-boot . Happy New Year!   

 

The Eat My Dirt brake shields were sent my way on the basis they had “Michael Stenning” written all over them. These are primarily designed to protect disc brake/rotors from a sticky coating of spent lube when re-lubricating a thirsty chain. Same goes for tyres and rims.

Story goes these were invented after Jon fancied a quick blast on Gary’s bike. Unbeknown to him, Gary had “just chucked a bit of oil on his chain and cassette” seeing as they were looking a bit dry…

Mid wheelie, Jon engaged the rear brake…Nothing. Next thing he knew he was flat on his back and the concept was born.  Being marine engineers, they made a prototype from cardboard and refined the design with some input from Huddersfield University.

The brake shields are essentially a massive “bib” that clips on in literally seconds once you’ve got the knack. Bike Bib was their intended moniker but it seems, Michelin own the name “bib”…

Ultimately, they decided polypropylene was the ideal, flexible, chemical resistant material. In fact, they are so confident in its longevity, they will replace free of charge and under normal use, so long as you send them a short video explaining how they failed.

First slip the shield behind the cassette and secure the tab around a convenient spoke. Clip the top hook around another spoke and check it won’t move when you rotate the cranks backwards.

Once you’ve cleaned and/or re-lubricated your chain, unclip and flush the channel through with a bit of bike wash/concentrate and rinse that away using tepid water. Despite some initial scepticism; it’s beginning to find favour with me. http://www.eatmydirt.eu/brake-shield

Out of the blue, this Blackburn Piston 4 floor pump arrived on the SDC test bench-straight from the States. It’s a high volume model, featuring a steel barrel and base, which are welded together and finished in a very fetching gunmetal grey, a huge 3 inch gauge that goes all the way to 220psi.

Formative impressions are very favourable-these 35mm Clement were brought from flaccid to 90psi in a cool 38 strokes and my Univega’s 26x1.75 Vittoria to 80 in 50, both with minimal effort. As you’d expect from this end of the market, not to mention Blackburn, the build quality is absolutely top notch, with a really solid feel and refined action.

While looking at foot mounted gauges is hardly a hardship, the super clear top unit means there’s no excuse for over-inflation and if you do, simply  scrub off the unwanted pressure by hitting the head’s integral bleed valve.  

Other pleasant surprises include these uber lumen Meteor Storm Pro and Shield-X lights from their UK importerwww.raleigh.co.uk . In recent years, high power systems have become increasingly compact, especially for the road market. The Meteor storm pro boasts a range of steady settings delivering between 1700 and 125 lumens, which is very impressive from a torch type with integral battery.

On paper, this range should cater for everything from race pace antics along unlit back roads to urban commuting. Admittedly offset by 6hour charge times, a quoted run time of 2hrs with the full 1700 on tap is pretty reasonable given its fuelled by a 3.6 volt 3200mAH cell…Buying a second will obviously extend its potential, especially since those sorts of charge times aren’t the most convenient for desk bound commuters.

Spec wise, we have two Cree XM-L2 diodes, CNC machined aluminium casing for durability and excellent heat displacing qualities and an automatic shut down in the unlikely event of overheating.  No less than ten modes, including a 2000lumen flashing “day” mode that they reckon will run for a claimed 38hours. 

Those looking at the bottom line will point out that high power Cree units complete with battery and charger can be picked up online for around the £20mark. True, these offer a lot of bang for little buck but tend to be a little unrefined in terms of delivery. Three modes, run times around5hours in top are quite enticing and in my experience, practical for longer winter training runs along unlit roads.

However, reflector and lens quality tends to be bargain basement, so while there’s enough bite for 35mph plus on straight sections, they tend not to be so useful in the twisties.

They’re decidedly overpowered in the suburbs, let alone town centres too, which is where those with more intelligent, multiple modes score highly. On a completely different note, I found myself roped into photographing a wedding at a days’ notice-one of the biggest textbook no-no’s for any photographer.

However, I had trusty CSCs and a few suitable lenses, so was happy enough to help out; on the understanding it was a favour. Despite some initial trepidation, the Baptist ceremony went surprisingly smoothly. I was even asked by one guest, if I had photographed her wedding 22 years previously (!). Right, off for a chat with Tegan Philips about her bike, Axel

A Slippery Scapin's Starry Makeover

Increasingly superseded by stainless, chrome has long been synonymous with Italian manufacturers, despite Columbus recommending their tubesets were not subjected to acid baths, filing and similar torture...

Scapin are an Italian marque, renown for coating their steel frames internally with phosphate and nickel plating the exterior tubes. Allegedly, this was also for corrosion resistance, though I remain convinced aesthetics were the biggest pull. This particular example came under my radar, while I was mooching around Maldon Shot Blasting & Powder Coating’s bat-cave.

Closer inspection suggests it was fashioned from Columbus’ thin wall Nemo or Genius tubing. I strongly suspect it was originally part-painted like this Rossin but chemically stripped once the livery had begun losing its tenure and/or succumbing to stone chips and other cosmetic damage.   

Persuading stove enamel and 2pac finishes to stay put on partially/ plated framesets has presented headaches a plenty for paint-shops. Acid etch primers ruled by default but given a few years’, the livery tends to flake and peel where the two overlap.

This customer has chosen to leave the rear triangle in its original polished state. Aesthetics aside, this means chain slap and hasty wheel removals won’t leave unsightly calling cards. Graham carefully mummifies these with masking tape to rule out any pitting from blast media.

Having passed the threaded uni-crown forks through the iron oxide cabinet, Graham decides to sand the main triangle. He fears even a gentle grit could lift the nickel in places, which is not something that can be disguised with additional paint. 

Instead, he opts for an epoxy based zinc primer. Epoxy offers superior adhesion and interestingly, resists chemical attack better than others. However, they aren’t UV stable; hence polyester powder is the good finisher’s choice for colour coats.

After meticulous plugging and masking of head, seat tube and threaded areas, the frameset disappears beneath a powdery grey mist. Seven minutes and some perfectionist re-touching later, its spirited off for a ten minute bake in their gas oven.

Monitoring progress around the seven minute mark, the powder has melted to a rich (and strangely attractive) grey skin. Next; Graham applies a gloss black, a common “colour” that including lacquer brings the price to £65 plus VAT. However, this is only the base for a very exotic commission.

Four minutes and some localised re-touching later, its back to the curing oven for another ten minute bake; I alter the camera settings slightly and sip some tea, while Graham heaves a huge box of powder across the workshop dung beetle fashion. “Sapphire Star clear coat” he shouts over. 

I’m told this acrylic is impregnated with tiny pigments of colour. The overall effect is timeless petrol blue under normal lighting but assumes a subtle sparkle on sunny days. It’s well known that colours have slightly unique characteristics, requiring different techniques but Graham explains; particular care is needed with this kind of specialist clear coats-including temperature. 

The Scapin must not be allowed to cool, otherwise crazing or clouding is on the cards-disastrous. Gun loaded with lacquer, he strides purposefully over to the oven, caresses the frame tubes, nods with a grin and retrieves the frameset.  

Powder lacquers always appear white, enabling the sprayer to see exactly where they’ve been. Anything other than exacting coverage here will ruin the effect but like any skilled trade, he makes this look effortless-done in five minutes. 

Back to the oven for another ten minutes, we’ve time to indulge in a biscuit; or three. Graham removes the masking tape while the adhesive is still soft and I get a final shot.  

Total cost is £162 including VAT.      

 

    

Happy Holidays

Managed to steal away to the midlands for a few days and got a look at John Moss’s new fully faired Sinner Mango. He only took delivery the week before and I first spotted him whizzing past on Christmas morning while I washed and waxed my KA.

Frustrated at finding myself bereft of camera, thus missing that moment, I subsequently emailed John and we arranged to meet before he headed out for a Boxing Day blast down to his sister’s.

Speaking of the elderly eight-valve Ford, 150,000miles marked another full service (£122 including parts, labour and VAT). This basically consisted of 10w/40 engine oil, filer, pollen filter, grease and other top-up fluids.

Christmas night was spent doing some light trace photography, which drew the attention of several passers by and of course, the law. Thankfully, everyone was brimming with seasonal cheer and ultimately, left me, tripod and Samsung mini CSC unmolested.

John has taken the electronic option in case he should run out of grunt many miles from home but has been topping 33mph on the formative, local outings and under his own steam.

Glancing inside the Kevlar shell finished in yellow 2pac and integrated electrics/lighting aside; the layout is reminiscent of Mike Burrow’s iconic Speedy/similarly high end recumbent trikes.  Twist grip shifters command a Rohloff hub transmission and more traditional front mech, double ring set up.

He’s added a bit more cushioning around the headrest and is sticking with the hard shell, all weather cover. Suffice to say, he’s delighted, less so the couple’s cat’s, who are now barred from the workshop!

Elsewhere, rumour has it Lee Cooper is making a return to building under his own name and Heidi, my intern has been working on the social side of Stenning photographic. I have already lined up some interesting photographic projects and working on relocation. A new batch of test kit is also keeping me productive and out of mischief during the corridor between Christmas and New Year.

Contact points are extremely personal, so guaranteed to divide opinion. In terms of damping and control, I’ve always liked Lizard Skins DSP range, although it’s much higher maintenance than corks or similarly traditional coverings. Silicone rubber is beginning to enter the fold.

After six months daily service and despite some tell-tale stretch marks (resultant from minor over-tensioning), the Genetic wrap remains in rude health six months and many mucky miles hence.

Widget components also offer a similar covering, this time with a dimpled texture for improved grip in really wet, slippery conditions. This one costs a few quid more and comes in five colours, complete with expandable wedge plugs.

The naturally sticky texture rules adhesive backings redundant, meaning it’s easily unwound to correct aesthetic imperfection and doesn’t render it bin fodder in the event of cable replacement or handlebar swaps.

Most coverings are pretty generous these days to accommodate broad, oversized drops, so I wasn’t surprised to discover eight inches or so apiece leftover on these curvy Salsa Bell Lap-even with double ups.

Our green was interesting too. Aside from being an obvious choice for the teenage dream, it appears to change colour depending on the light-fluorescent when it’s overcast, less garish in brighter conditions.

Thus far, purchase, comfort and control are living up to the hype and while greater owner involvement is needed to keep it clean, compared with corks and leatherette types it’s not proving highly strung in that respect either.

Right; back to testing-lots of blinkies and commuter combos to put through their paces, some 700x25c tyres and strategies to complete before mid January 2016.             

         

Makeover Magic: The Ilpompino's New Clothes

Sometimes deadlines are like a slow but consistently burning fuse. Having caught up following last weeks’ IT crisis, I headed off to Maldon Shot Blasting & Powder Coating to witness and document my frames’ transformation stage by stage. 

After the usual pleasantries, conversation turned to other enticing projects booked with them including lugged n’ brazed 531 frames from the early 1990s and various classic car shells/chassis awaiting blast and/or structural repair.

Chris examined the Ilpompino’s factory livery and decided it was best left soaking in their methyl chloride tank prior to blasting. Sometimes, depending on the existing paint, it’s possible to skip straight to the blast cabinet.

Once the active ingredient in over-the-counter stripping products; methyl chloride is a nasty carcinogenic, so now the preserve of controlled contexts. This is diluted with water to prevent evaporation but agitating the depths unleashes an unmistakable, pungent odour.  After fifteen minutes marinating in the stagnant looking chemical soup, Chris dons rubber gauntlets and delves deep.

My frame emerges seconds’ later, almost completely bare save for some localised residual silty paint. Passed through the glass bead cabinet and several minutes’ intensive tickling reveals a bare, dimpled surface; it also confirms my initial suspicions of surface pitting where the salt monster had nibbled the right chainstay.

This doesn’t dictate Metafil, or similar specialist fillers but Chris gently sands it flat before masking and plugging threaded sections. Critics of powder coating cite that achieving two or more colour effects requires applying 2pac or similar wet spray paints atop. This is relatively labour intensive, costly too...

Given this backdrop, a two-tone powder coat finish sounds a bit risky but Chris and Graham seem completely comfortable with the commission.

Regardless of family, all paints have unique characteristics according to their colours/pigments. My French blue/grey effect leads Graham to introduce a thinner, corrosion inhibiting zinc phosphate primer, which won’t risk imperfections in the top coats.  

Midway through this formative stage my Sony Alpha SLR camera body gets the sulks. Despite frantic efforts to re-dial settings, it refuses to deliver three frames per second required. Hastily diverting to my trusty NEX5 ensures there’s minimal loss of footage.

Confident of even coverage, “Izzie” is passed through the curing oven for fifteen minutes and our attentions turn to locating French blue (5024) and a complimentary  grey.  A hearty cheer erupts, signalling both polyester powders are in stock and in plentiful quantity.

Graham starts by loading the 5024, confirms a good flow rate by depressing the gun a few times and returns to the curing oven. Moments later, the frame is earthed and ready to receive the colour coat. Graham covers the main triangle under a blanket of pale blue before checking the powder is heaped uniformly throughout. Two affirmative nods and it returns to their their curing oven for ten minutes at 200 degrees.

Conversation meanders to the frame’s history, how I came to acquire it and its significance to me. Having returned to the oven, we discover gallons of molten frame preserve racing from the vent holes and bottom bracket shell...pooling  on the concrete floor.

Mercifully, this hasn’t contaminated the colour coat and can be deftly dismissed but serves to illustrate the importance of warning your frame builder or spray shop, should you suspect a frame has something oily sloshing around inside.

The boys take it all in their good humoured stride, blowing the frame through with compressed air. Demon purged and our next dilemma is whether to start the grey as a solid, or gradually fade it in atop the blue.

Solid effects involve masking, which in this context, risks permanent “tan lines”; so we take the latter route. Unlike wet sprays, powders can be blown into new shapes, or reused. Meticulous in their approach, Graham revises this three times before progressing round the rear triangle.

Moments pass, tension mounts as his eyes painstakingly scan every last particle. To my relief he nods again before spiriting it into the oven once more.  Finally, my beloved frame is given an acrylic clear coat, which adds further protection, while accentuating its rich, glossy lustre.

Right, time to introduce some fresh home brewed frame preserve and helicopter tape to abrasion prone points; then I’ll build it up before October’s through.

Heartfelt thanks go to the team at Maldon Shot blasting and Powder Coating for undertaking this transformation www. http://ctc-powder-coating.co.uk/.

Trevor (Father and MSBC MD) has asked me to point out that cost for this kind of specialist effect varies wildly depending upon several factors. This includes colour choice(s), post blast remedial works and whether decals/other detailing are required.
