When Things Go Smoothly...













 I’ve seen a bit of bar con bashing online recently. In common with others who are vocal in their destain for things, much of the comments come from ignorance, so are arguably irrelevant. Some suggesting cables run THROUGH the handlebars. Sure, they’ve fallen from mainstream gaze and lack the light, snappiness of Brifters but they’re also lighter and ultra-dependable. Great for back of beyond touring, beasts of burden, and indeed, daily drivers like Ursula.  

Microshift still makes them (and continues the dependable theme with their Sword and Advent group sets). Hot on the heels of the Spyre SLC, Ursula’s rear Shimano CX50 cantilever pads had gathered some glaze and needed a quick scrub. It also presented the opportunity to strip and lightly grease the posts. The straddle wire was also beginning to look tired, so was also replaced. Consumables are eaten quickly through winter, especially if you do bigger mileages.  

I’d spotted a rear Tiagra mech, pads etc being sold as bankrupt stock and at very enticing prices. Sad, since it’s never good to see, or hear of businesses going to the wall. In the late 80s, it was common for people without business acumen, financial literacy, or experience to open enterprises and often fail catastrophically. However, it's become increasingly prevalent for established and successful traders in post-Brexit Britain    

Little and often maintenance becomes second nature, extends the life of components, and usually stops trouble before it starts. I’d applied a light helping of Muc-Off HCB1 to Ursula’s chain stay bridge area and the BBB Echelon saddle rails, which were showing some localised corrosion.  

Again, nothing to get excited about at this stage and HCB1 will mothball, stopping surface grot in its tracks. Yes, generic maintenance sprays will certainly help on this front, but need more frequent reapplication and are readily washed away. They’re meant for light lubrication of cables, and pivot points, flushing wet, corrosive stuff out, priming chains removing muck, and grime, loosening sticky/lightly corroded parts    

Back to the Holdsworth 

Having removed the Woodman Jupiter’s lower cup cum race with a few deft taps of my trusty crown race tool. (It also needed a little chemical assistance, courtesy of some Muc-Off MO 94). I set it carefully on the Holdsworth’s crown and decided there was sufficient Park PPL100 TESTED: PARK TOOL POLYLUBE 1000 LUBRICANT FOR BICYCLES (sevendaycyclist.com) grease dressing its needle roller bearings, so just transplanted.    

 

The Jupiter’s design means it's extremely well-sealed from the elements, so an obvious choice for MTB and XC duties. Ironic perhaps that the Holdsworth and Teenage Dream are fair-weather playthings, but the Woodman’s design and refinement (coupled with the fact decent-quality headsets were becoming harder to source) swung it for me. Forks in, it was simply a matter of stacking up the spacers, refitting the cockpit, connecting the front brake, adjusting pad height, and the usual tweaks.  

 

I like the slight contrast between frame and fork, accentuated by the Knog NERD computer’s blue silicone casing. Had the fork been any darker, it would’ve looked a little too obvious (although could be toned down with a comparable, darker shade of blue bar tape). Anyhow, mission complete.  

 

Elsewhere, the switch to MKS NJS chain tugs subverts the need to detach the Topeak DX rack when accessing track nuts- adjusting the chain tension or removing the wheel-problem sorted.  

 

I decided now was the time to see how well the Peaty’s Speed Grease PEATY'S SPEED GREASE | cycling-not-racing (sevendaycyclist.com) was holding up on Ursula’s Hollowtech II axle, given the flooding and generally adverse conditions of recent months. It also presented an ideal opportunity to give the rings a good scrub. As the photos suggest, a reasonable amount of Peaty’s remained and was still doing its friction-busting, corrosion-stopping thing.  

 

However, I’d come this far and opted to strip and introduce this Wolf Tooth WT-G Grease. It’s a synthetic blend designed primarily for moving parts- hubs, headsets etc but apparently fine for contact points and threaded parts. Its reckoned stable between minus 50 and 180 degrees and promises low friction, longevity and high resistance to water, oxidisation and corrosion.  

 

The crank’s pinch bolts were completely devoid of grease, so were a little reticent to release. Nothing a shot of MO94 couldn’t sort, so I was sure to add a generous lick of the Wolf Tooth grease to them before refitting and torquing down to the recommended 12-14nm. Buttery smooth once more. The headset’s bottom race came next, and I stripped the rear Shimano CX50 brake, greased the canti posts and replaced the straddle wire.   

 

Talking of which, it's much easier to apply than some higher viscosity formulas – Juice Lubes Bearing Juice being a case in point, although the latter is really stubborn and being so thick makes a great host for loose balls. No escapees in the hub shell. However, the Wolf Tooth is supposedly designed for contact points and similar duties too, so I’ll be checking that out in the coming weeks and possibly months 

 

Having switched the Holdsworth’s Miche Primato calliper for the long-reach Tiagra, I decided now was the time to upgrade the Teenage Dream’s lower end Miche Performance. Plenty of life in the pads, so I gave the callipers a quick clean and polish and bolted everything together. I’m sure I have the rear Primato somewhere in the spares stash. I’ll upgrade the Teenage Dream’s rear Performance unit when I unearth it. I'll close here with Steve's review of the Castelli Entrata Tights https://www.sevendaycyclist.com/castellientratatightsnopad

Tubes, Lubes & Tape Tribulations

 











I’ve been taking advantage of primarily dry conditions and defaulted to the Teenage Dream’s skinny-tyred charms. Down tube friction shifters aren’t everyone’s thing but these and the Campagnolo Victory mechs they command, are slick and reliable.  

Sure, I wouldn’t race with friction setups, but for training and general riding along open roads, fine. Went to pluck it from the hook for a dawn ride, only to discover the rear tyre was pancake flat.  


No matter, Ursula needed a run and I needed to double-check the Micro shift/Sun race/Shimano drivetrain was still playing nicely.  


Dialling in a stiffer spring tension was definitely the way forward. Not that I was pogo-ing, just a little too reactive for my tastes and the machine’s loftier stance. Crisp, seamless and predictable shifting, a big grin across my face as my mind roamed freely. 


Sorted the Teenage dream’s flat on my return-a sharp had nicked the rear tyre’s casing and grazed the tube, so pressure loss was, thankfully incredibly pedestrian. Struck away from the seam, so easily patched. Back into the wedge pack, as a spare. The chain was beginning to look a little thirsty.  


Nothing serious, but now was convenient. I stripped the chain with solvent, dried and switched to the Peaty’s Link Lube Dry PEATYS LINK LUBE DRY CHAIN LUBE | cycling-not-racing (sevendaycyclist.com). Curing times are less convenient than the Tru Tension Banana Slip All weather LubeTRU TENSION TUNGSTEN ALL WEATHER LUBE | cycling-not-racing (sevendaycyclist.com) but its clean and surprisingly durable.  


In common with other waxy type dry lubes, residual stuff clinging to the freewheel/cassette gets reclaimed by the chain, extending topping up times. Ursula is still running the third helping and I exceeded 400miles on the second. Chances are, I’ll switch to The Peaty’s Link Lube Wet, come the next replacement chain, which will probably coincide with October.

  

The Link Lube Wet is proving a great fit for the fixed’s KMC chain-keeping it serene and quiet. Both machines sport silicone bar wraps and I’m a huge fan of their damping and grip-hell and high water. The one minor downside, especially with bright colours, is the ease at which they accumulate grimy patinas.  


On the plus side, they can be tossed in the wash at 30 degrees, when really sullied. However, this is hardly the most desirable route when you’ve just fixed a flat by the roadside and grabbed the bars with slightly oily digits.  


Dark colours are the best bet, especially for daily drivers but then again, I like something quite bold for winter. Foaming type waterless cleaners get the worst out but be prepared to give them a regular tickling with a medium stiff brush (I’m really fond of Oxford Products Tyre ScrubTESTED: OXFORD PRODUCTS TYRE SCRUB BRUSH (sevendaycyclist.com) dipped in neat degreaser/bike wash concentrate and rinse with warm, then cold water.     As if by magic, some Velo Orange Rubbery Bar Tape arrived in the post-Thank you Connor.  I’ve gone for black but white, or a tan brown are the alternatives. Rubbery texture aside, it’s also 3.5mm thick, which promises excellent damping.  


The nights and mornings are gradually becoming darker. I run the K-Lite dynamos during the day but now the mornings are getting darker, blinkies are engaged for most rides-usually the Ravemen CL05RAVEMEN CL05 SENSORED REAR LIGHT | cycling-not-racing (sevendaycyclist.com) and CL06 RAVEMEN CL06 SENSORED REAR LIGHT | cycling-not-racing (sevendaycyclist.com) but I’ve also taken to mounting the Moon Sheild X Ultra MOON SHIELD X AUTO REAR LIGHT REVIEW? (sevendaycyclist.com) on Ursula’s Carradice SQR Tour.  

A nice height, closely aligned with driver eye levels. It’s a model that is slightly “Marmite”. Some (such as yours truly) think it’s fabulous, others feel it’s anything but user-friendly. There are 9 modes in total, which is excessive by some standards, and I must admit, I default to the flashing modes, since for me, they strike the best balance between output and economy.  


I’ve also needed to add a shim between the K-lite Bike Packer Ultra lamp and Velo Orange mount, since the former ad a tendency to migrate upwards-very slowly-washboard tarmac being the main culprit. Aside from being mildly irritating to me, I didn’t want it dazzling oncoming traffic. Nothing a quick delve through the bodge box and two fresh cable ties couldn’t solve.  


To date, I haven’t given much thought to replacing Ursula’s rear Schwalbe Marathon Mondial DD. It’s still perfectly serviceable. The Schwalbe Marathon GT 365TESTED: SCHWALBE MARATHON GT 365 TYRES WINTER UPDATE (sevendaycyclist.com) is an obvious substitution. These are exceptionally reliable and extremely durable. However, they are also hefty, and I fancy something sprightlier.  


There is still a reasonable amount of decent quality 26inch rubber around but it’s losing favour, just as 27inch did, I the late 80s. Supply issues are another problem here in the UK. Masked by the pandemic, European manufacturers are in no hurry to export to the UK, given the added paperwork and delays, which are likely to worsen in the coming months.
