Inflated Egos & Lowered Expectations




 








If there’s someone you know who loves you but is taking it all for granted, they may lose you someday... Bread’s “Everything I Own” (Covered by Boy George and others) reworked -a song resonated very strongly with me for a good 35 years. The years have taught resilience and self-reliance. Sometimes very brutally. A few have come to my rescue in ways I cannot begin to repay-at least not like-for-like but otherwise, I have a fiercely independent, survival streak. One that serves me very well, thank you.  


Given last week’s “ordeal” I was rather touched to discover Extra UK Extra UK had sent me this Topeak Road Master Blaster model, a traditional frame fit reckoned capable of an eye-watering, bicep-busting 160psi. It also mounts nicely along the top tube, sheltered from the silt, water and generic ruinous nastiness.  


They also sent me the Topeak Nanomaster Duo Fixer CO2 cartridge kit, which will hopefully help with the rapid get up n’ go following those hopefully infrequent flats. Most reading this will undoubtedly be quick to point out Co2 escapes butyl faster, so there’s a good chance the tyre will be pancake flat come the next day. Don’t panic, whip out the track pump (or bike-mounted inflator, if you’re mid-tour/bike packing escape.) and inflate to taste.   


Talking tyres, I’m looking forward to exploring some of the more technical forest trails, bridlepaths and unmade roads with the Maxxis Ikon, when they arrive. Not to mention seeing how well the Mud Hugger Evo and budget rear guard perform in these contexts.  


Both have met my expectations thus far and the former’s low-slung aesthetic belies decent mud clearance and I’m not expecting any clogging hassles. The wallet-friendly rear hasn’t turned to blancmange either but then, given its price, I had lower expectationsCloser inspection revealed the Axiom Oceanwave City+ Seat Bag AXIOM OCEANWAVE CITY+ SEAT BAG | cycling-not-racing (sevendaycyclist.com) had been aligned slightly downward, rather than being level, so took this opportunity to correct. An easy job, thanks to the Rixen Kaul  

I’m also keen to try the 700x32c Maxxis Re-Fuse-on my fixed gear winter/trainer. Allegedly they “refuse to puncture”. Specification promises good wear and puncture resistance.  

The 60tpi single compound casings employ the brands’ silk-shield technology (used in the Overdrive Excel) runs bead to bead and is boosted by an aramid layer.  


Will be interesting to see how they compare alongside old favourites such as the Kenda  Kwick Journey KS Plus Tyres KENDA KWICK JOURNEY TYRES | cycling-not-racing (sevendaycyclist.com).  the Kenda is cheaper and “only” feature a 5mm (about 0.2 in) puncture repelling belt along the centre strip, but I only succumbed once in several thousand miles


1200 miles down the line, I’ve hit my third puncture with the Maxxis Overdrive Excel Maxxis Overdrive Excel Tyre | cycling-not-racing (sevendaycyclist.com) in fairness, the two were on the same occasions and caused by very sharp flints that had pierced front and rear casings. I pulled these free and superglued the cuts. Replaced the tubes with fresh and repaired the wounded, consigning them to spares.  


When it comes to winter, working and competition bikes, reliability is paramount- Sunny days playthings and other “best” bikes are a little more nuanced perhaps. Talking of which, I’m hoping the weather and infrastructure are going to improve, so I can get some miles in with the Teenage Dream and the recently mounted CST Cito. It’s still rather soggy, changeable at best.  


I’d crossed the 480-mile mark with the Zefal, before replenishment called (which is around 200 miles more than the Muc-off Wet lube in comparable contexts). Now it shouldn’t be inferred that the Muc-Off is a poor lube-it's not, rather it serves to illustrate the difference between a most conditions, year-round “every person” wet formula and a hell n’ high water blend.  


This coincided with the two flats, and I took this opportunity to give Ursula a good clean and strip the residual Zefal in favour of the Motoverde  PTFE Chain Lube Motoverde PTFE Chain Lube | cycling-not-racing (sevendaycyclist.com)  However, headed off-road, I’d shy away from river crossings and waterways, since PTFE and similar forever chemicals are very harmful to aquatic life and the ecosystem generally. Talking of bike cleaning, here’s my review of the Finish Line Easy Pro Five Brush Set Finish Line Easy Pro Five Brush Set | cycling-not-racing (sevendaycyclist.com) 


Bob Elliot & Co have sent me these FLR F70 PRO MTB 250 and appropriate, given the mtb theme Safety Labs E-Bahn 2.0 'MIPS' Urban Inmold Helmet in Black. It will be interesting to see how this compares to the Lazer Chameleon Lazer Chameleon Helmet | cycling-not-racing (sevendaycyclist.com)

Cagey











 This Super Sparrow lightweight thermos bottle arrived and having established incompatibility with broadly standard, composite cages, I decided it was time to revisit Ursula’s downtube setup. I’d gone for the Fidlock Magnetic bottle holder TESTED: FIDLOCK MAGNETIC BOTTLE HOLDER AND BOTTLE (sevendaycyclist.com) and popped a chain checker there- a talking point for some, while still leaving me scope to mount a couple of composite cages on the underside and seat tube.  

This didn’t overly impair my ability to carry water/similar fluids. Now, I’m very fond of the Topeak Modula XL and the now discontinued BBB Fuel Tank XL LONG-TERM TWELVE MONTH TEST: BBB FUEL TANK BOTTLE CAGE (sevendaycyclist.com) cages, since you could whack a 1.5 litre bottle of mineral water, or indeed a similar soft drink in situ, without fear of their ejection (or indeed, knackering a traditional cage).  


However, they will often prevent mounting one on the seat tube. The Free Parable Monkkii Cage FREE PARABLE MONKII CAGE REVIEW (sevendaycyclist.com) is another useful choice, provided you’re not lugging too much weight. 1.2 kilos (as distinct from the 1.5 kilos cited) which should entertain a full 750ml (about 25.36 oz) flask or bottle. An obvious “from the box” solution. I’ve hauled disposable Argon/Co2 welding gas bottles in them, although placed some bubble wrap between cage and bottle to rule out any potential dings in Ursula’s down tube.  


However, to my astonishment, both the BBB and Topeak were too roomy to hold the (bottle) securely. After some rummaging through the cage stash, I whittled it down to a Van Nicholas titanium (Elite Ciussi pattern), a side entry Zefal and this Boardman winged carbon fibre design.  


Lo and behold, the Boardman wonThe main issue with the 6061 and Ti models boiled down to scratching the bottle’s finish. I’d bound some old bar tape around the Van Nicolas and strangely enough, that spark of inspiration proved fruitful.  


Then, along came this Topeak Modula Java.  

It’s an adjustable composite model, which on paper should lug the thermos in question without missing a beat, or launching it mortar style at the first hint of lumpy trail. I also received the brands’ Gravel 2 Stage Mini Pump, which as the name might suggest has two modes- high volume and high pressure, so you can recover from a flat efficiently.  


90psi is top whack but aluminium construction bodes well for longevity and means it stands a sporting chance of hitting these pressures. In some respects, mini and midi pumps have ruled the roost for good reason. Aside from supporting a clean aesthetic, being stashable in a jersey pocket, or bigger wedge pack means the valve end needn’t get caked in crud.  


Many road-biased riders use Co2 as their first line of defence, pump second. Makes sense, especially if you’re needing lofty pressures, although bear in mind you will need to reinflate given though Co2 will rescue you, it will escape butyl much faster, so expect to be busy with a track pump the next day, as they’ll be close to pancake flat. Many mini-pumps will genuinely achieve road realistic pressures too, although, around the 100psi mark, my biceps have felt close to comedic explosion.  


I still have firm fondness for Lezyne Micro Floor Drive HVG (High Volume) and high-pressure models, which resemble track pumps that have been put through a matter-shrinking device. CNC machined construction marries strength and great looks but they’re around 216g (including mount) and on mine (c. 2015) their composite mounts felt a little whippy, meaning the head could rattle against the seat or down tubes “Woodpecker” fashion when riding across washboard tarmac and of course, dirt roads.  


Placing “helicopter” tape, such as this Zefal Z Armor ZEFAL SKIN ARMOR ROLL | cycling-not-racing (sevendaycyclist.com)  over those areas of the frameset will deaden this, while protecting it from potential finish damage. Talking of protectants, I’ve been pleasantly surprised by how well the Weldtite Rapid Ceramic restored the anodised finish on Ursula’s faithful Lezyne Tech Drive HP pump   

 

In my book, frame fit pumps still have their place and hugely different from the giveaway models sold with complete road and touring bikes 20-30 years ago. The sort that might deliver 60psi with herculean effort before locking out uselessly, or worse still succumb to a bent piston.  


Steve and I are very fond of the Zefal HPX High Pressure Frame PumpZEFAL HPX HIGH PRESSURE FRAME PUMP | cycling-not-racing (sevendaycyclist.com)  and I find them aesthetically pleasing on an older steel-tubed road/touring build. These tend to be Presta but could tackle a Schrader valve, more commonly found on trailers/tagalongs with an adaptor, like that belonging to the Merida multi-tool I’ve resurrected.  


Then of course, there’s the Specialized that I acquired back in the late 90s and ultimately euthanised itself beneath the wheels of a passing double-decker London bus. I was offered one recently that “appeared to be working” and mine for £44. I laughed like a hyena and went about my business. In common with Kirk Precision framesets and of course, Specialized’s Rock Combo, I’d give it a loving home but not paying fancy prices.
