Tubes, Glorious Tubes















 During the dying embers of 1979, I recall a Z-list comedian letting a balloon roar flatulently into the crowd, quipping “That’s what Mrs. Thatcher needs...Deflation!!” Fast forward 43 years, prices of food and other essentials are rocketing. Inflation is at a sobering 9%… 

Moments from home I was struck by another, all-too-familiar sinking, and squirming, as I engaged Ursula’s front brake. Yup, the Vittoria Evolution had succumbed to a sharp flint that had lodged within its chevrons and burrowed into the casing.  


Blowouts are rare.  


Most punctures follow this narrative and this one had the grace to hold off until I was parallel to home. Being 5.55 am, I simply switched the Ryde/Alfine Shimano Alfine UR700 Hub Dynamo | cycling-not-racing (sevendaycyclist.com)  for the Ryde/Shutter Precision SD8 SHUTTER PRECISION SD8 HUB DYNAMO | cycling-not-racing (sevendaycyclist.com) shod with a Schwalbe Land Cruiser, which employs a similar level of puncture resistance to the Vittoria and broadly on par, price-wise.

  

My first flat in 750 miles, too. Inspecting the tube revealed a tiny pinprick, which was easily patched. I left it hung up and inflated while replenishing the patches in my two kits, while on my mind.  


I had some business in the midlands and made arrangements to leave my car at John Moss’s house. LOVE RESURRECTION: JOHN AND JANE MOSS'S TANDEM TRICYCLE (sevendaycyclist.com) 

Transpired he and Jane are doing some “Swedish Death Cleaning” so very kindly gifted me a batch of new, unused tubes (700x32 and a 26x1.5) which was very welcome and extremely kind on their part. Ironically, I returned to discover two 25mm Eclipse Road inner Tubes and this Kask Protone Icon Helmet awaiting me.  


The Tubes are TPU and reckoned not only to be lighter but reduce rolling resistance while being more resistant to flats. These feature a welded valve stem, which is also reckoned to be superior to bonded and glued types.  


The Eclipse are also reckoned repairable, although dedicated patches require a decent curing time-overnight, ideally. So, I’d be inclined to carry a butyl spare, or two just in case. These are earmarked for the Teenage Dream, which frankly, is the most obvious candidate, save perhaps for the Holdsworth...  


Weather conditions have presented opportunity to go out and enjoy my beloved road bike and given its presently sporting the now discontinued A520 pedals, I’ve clicked in and racked up some miles with the Shimano MT701 shoes.  


Took me a few rides before this incarnation of the Boa lacing system became truly intuitive. Well, release was the issue. I’d gone into Child-at-Christmas mode, without reading the instructions and couldn’t work out how to slacken the laces. This is just a matter of pulling the Boa wheel upwards. The MT701 are increasingly becoming my go-tos for general riding.  


That said; think I’ll stick to the Quoc Pham Tourer when it comes to the Teenage Dream since the soles are that bit stiffer. As for the PD ED 500 pedals, no surprise to learn I’m warming to their charms as the miles rack up. A good bet for touring and indeed, light, dry trail work. Dare I say the G word... 


I managed to lose a spoke magnet on Ursula’s Ryde/Alfine wheel but thankfully, I had a couple of generic, auction site specials in stock. I was also slightly surprised to find the Cat Eye Viz 100 LED light had lost its USB plug. Porting it beneath the saddle, thus sheltering it from rain and spray, was the obvious move. 

 

Talking of which, I’ve concluded the Teenage Dream’s saddle height was just a fraction too low, so raised it by a few milimetres- now perfect. Must’ve been when I re-greased the Thompson post, using the Peaty’s Bicycle Assembly Grease PEATY'S BICYCLE ASSEMBLY GREASE | cycling-not-racing (sevendaycyclist.com)

Who Loves Ya Baby?











 My Univega’s front Continental Speed Reflex tyre succumbed to a slow flat, inducing some squirm and prompted a switch to the Schwalbe Kojak. It also provided an ideal opportunity to check pads for any imbedded contaminant etc. To my surprise, the comparable 26x2.0 Kojak are considerably lighter than the Continental (527g against 675g) which may be attributable to several factors.

While both tyres are wire beads and similarly matched in terms of puncture resistance (at least by their respective ratings) the Continental’s sidewalls https://www.sevendaycyclist.com/continental-contact-speed-reflex-ty  seem a little beefier. They are supposedly designed to entertain tyre driven bottle dynamos, which may account for this differential. Not that I’ve felt any inclination to try, since I’m a hub dynamo devotee and wouldn’t revert by choice.

The Kojak seem to roll a bit faster (not that the Continental could ever be considered remotely sluggish) but the Kojak can also be run at 70psi, the Speed Reflex a more modest 58psi).  

Whether these features will have implications for durability and puncture resistance remain to be seen, especially as we transition from mild, breezy conditions to wintry stuff. However, I’ve also switched to some heavier duty Schwalbe tubes. Tubes are one of those components easily overlooked. The generic bundle types, though worthy enough tend to be a little on the thin side, which has implications for puncture resistance, patching and indeed, pressure retention.

Having reached my conclusions regarding the Tru Tension Banana Slip Wet Lube https://www.sevendaycyclist.com/tru-tension-tungsten-wet-lube , I’ve switched to the Zefal Extreme Wet Ceramic. Apparently, its’ a ceramic reinforced, Teflon-based formula reckoned to cling on, rain, shine, snow, and ice. The latter has been threatened on these shores. Some crisp 5am starts and glazed surfaces have been a slight culture shock, but confirmed that both tyres grip asphalt like the proverbial leach

Personally, I’m of the opinion these adverse weather predictions are designed to grab headlines and online traffic. Forecasting has also reached the point where it’s so accurate in the immediate sense, its ironically inaccurate longer term. Either way, I’ll be sticking with the Pro-Viz Reflect 360 Gloves https://www.sevendaycyclist.com/proviz-reflect-360-cycling-gloves  which seem to have most bases covered.  

I digress, back to the lube. A little certainly goes a long way. Literally apply a tiny drop of the white elixir on every, freshly cleaned link, give the cranks a few rotations (wiping any excess from the side plates) and you’re ready to go.  

So, what are ceramics, then…In this instance it refers to a microscopic layer designed to infiltrate and bond with the surface, theoretically protecting it from the elements and premature wear. Thus far, it’s certainly slick and less gloopy than many wet blends but I suspect good housekeeping (weekly wiping of side plates, jockey wheels and cages) will be mandatory.

With falling temperatures, layering is even more important. Primal Europe have graciously sent me these funky Comic Book arm warmers and Showers Pass, their Elements Jacket. Apparently designed with mountain bikers in mind but versatile enough for other disciplines and indeed, off the bike.

It’s a seam-taped 2.5 layer waterproof/breathable laminate with front pockets, core ventilation points, a removable hood and features a carbon print lining, which theoretically subverts clamminess and odours, which can be an issue with some 2.5 layer models, which I’ve otherwise been endeared to. Lighting is always a big draw, but particularly as the days are much shorter. I’m still very endeared to the Magicshine See Mee units discussed last week but this Lezyne Stick Drive is another neat design.

30 lumens isn’t jaw dropping by contemporary standards but the optical technology mean its very bright and useable, even in the lower settings. I’ve deliberated whether the 4lumen mode could be culled, although in common with some other Lezyne I’ve used in the past, it could be a life-saver, giving you something to limp home on, should reserves tumble.

Bright Lights Cold Nights





Second week in bedsit land and the boiler has gone bong, meaning no heating and hot water. Memories of the winter of ’92 are flooding back. At present, the temperatures are still creeping into double figures and this property is double-glazed. Therefore, the frosty glaze remains on the outside my window, when I don Lycra and head out for a 5am ride.

Cold showers and a vanishing toilet seat are less welcome, although said facilities remain superior to that infamous East London property 28 years back. Indeed, its 28 years since I bought my first LED light. A rear, two mode Vistalight that was essentially a reflector on steroids but a huge leap ahead of the basic, heavy filament lights that were the norm then.  

Enter these Magicshine See Mee lights. I have the 200, 180 and 100 versions on my test bench and am seriously impressed. The highest figure refers to the “Braking function” which kicks in for three seconds when their motion sensor detects deceleration/similar changes in momentum.

Formative impressions suggest these are too sensitive, triggered by washboard tarmac and longer climbs, thus putting a noticeable dent in run times. Thankfully, they can be switched off. “Braking” lights have become more popular but most I’ve used seem prone to these quirks, so I’m not singling the See Mee range out, per se.

The flashing modes are very effective and relatively frugal, across the board. The 200 also has a tracer light, a secondary diode that casts a 360degree flood at the road, to highlight bike and rider-again, fantastic in terms of presence and my inner child has grinned at the novelty value.

Talking of which, these are competitively priced. The 200 costs £33.99, the 100 £25.99. (At the time of typing, I’m not sure of the 180’s rrp). For the time being, I’m sticking with the Continental Contact Speed Reflex. These continue to impress with their tarmac hugging prowess, low rolling resistant and magic carpet ride quality. To my surprise, the Lezyne Floor Drive track pump’s gauge has expired. I’d had it for some years and it’s a really solidly made unit.

I didn’t want the hassle of buying and installing a replacement gauge, so I went the standalone route and this Topeak Smart Gauge D2. The only potential weak spot is the sprung head. I liked the original Smart Gauge, which came my way some 16 years back, which was a little simpler and had a press on head that would automatically morph to a Schrader, or Presta valve.

Alas after a few years faithful service, mine imploded rather dramatically. A backlight function would be rather handy, say when getting back on the road following a flat-my SKS Air Checker (in storage) has one.

Some would say for the same price, I could’ve bought another track pump but that would be wasteful, since the Lezyne is really well made and a standalone gauge is not only portable but the most accurate. Elsewhere, on the protective/winter front expensive crank arms can get a spanking. These Zefal Crank Armor https://www.sevendaycyclist.com/zefal-crank-armor  are an inexpensive way of protecting them from dings, stones, and other accidental damage. However, they won’t guard against unsightly toe-strap rub and may present compatibility niggles with some cadence sensors.

I was stunned to discover Control Tech are ceasing production of the Silicone bar tape, which I’m astonished, since performance is top notch, in all conditions. 155g (uncut, including CNC machined ends) might be a touch portly for bikes on calorie-controlled diets. However, for mile munching tourers, gravel, and winter bikes, there’s so much going for it.  Need something bike-themed to read as lockdowns come into force?

Magnetic Attraction






So, with freshly rebuilt dynohub wheel safely returned to me, and Univega waxed, following some mucky January mile munching, it was time to switch to fixed. 
Following frankenpute euphoria, you’ll imagine my dismay at a flickering and sometimes unresponsive computer display. Big fat flashing zeros are not cool.  
Let us be clear (as the present UK administration is so fond of touting). I had inserted fresh CR2032 cells, adding a slither of Vaseline to the battery contacts, nipped the sensor ties and magnet tight…Most probable causes isolated.
A seasonal Lurgy curtailed further diagnostics, but all seemed to be behaving normally. Both on the work stand and a subsequent mile long loop.
Three days later, back in the saddle, out along the lanes. Dynamo on, blinkies pulsing, erratic readouts... So, I switched the Trelock LS 906 https://www.sevendaycyclist.com/trelock-ls906-dynamo-front-light  lamp off. Consistently accurate, precise readouts resumed. Fluctuations gone.  This remained the case, over two rides and 45 miles.
I’ve never experienced these symptoms with my Univega’s Ultegra, or elderly Nexus hub dynamos. However, Strong magnetic forces, such as those experienced around power plants, and pylons are notorious points of interference. 97.6mph along a long, straight road, anyone? 
 I am also advised Shutter Precision hubs have particularly strong magnets.
Carbon fibre can also prove conductive, which is why good quality greases/assembly pastes must be used on metal components, to avert risk of galvanic corrosion/seizure. Bottom bracket threads being prime candidates. Could it be that the wonder weave, is amplifying said magnetic field, and creating these irregular signals?  
This may dictate moving sensor and magnet to chain-stay and rear wheel. Doing will exhaust computer and sensor cells a little faster. But provided I don’t exceed the 1 metre rule, everything should play nicely.
A wired unit is my last resort. Aside from defeating my “make do and reinvent narrative”, I’ll need to be more mindful when performing headset strips, and similar maintenance.  Blackburn have advised they no longer keep spares for the Atom units and, surprisingly, have deleted computers from their range.
Another rummage through the bodge box unearthed this VDO M3 WL, which appears to have a sensor fault. I’ve tried all the above techniques, but they won’t play nicely. Nor any other brands, for that matter, so I’ve emailed their UK importer for help. 
Despite constant headlines threatening a second ice-age, the thermostat has hovered around a seasonally typical 5 degrees.
No call for spikes just yet, although the wind chill prompted donning of Northwave Balaclava, once or twice.  These Oxford bright 4.0 gloves https://www.sevendaycyclist.com/oxford-1
have also come into their own and Steve’s been impressed by Proviz Reflect 360 CRS Plus Jacket https://www.sevendaycyclist.com/proviz-reflect360-crs-plus-jacket  
Chainsaw oil is continuing to do the business and some 140 miles in, is probably the closest to a bike specific, wet lubricant. I’m bargaining 500 miles from a single application. On paper, it’s looking a costlier option, compared with the bargain basement 5w/40. However, the latter attracted more scuzz. Most apparent within the cassette.
There’s been some further perch swapping, courtesy of this Pro Turnix gel saddle, which now graces my fixed gear winter/trainer. Its Selle Italia Novous boost superflow has been ported over to my tubby tourer and I’ve earmarked the BBB Echelon, elsewhere. Possibly the Goldhawk Roadax, if I can’t live with its stock/OEM model.
