False Senses of Security









 I was swooping around the bends, enjoying the pre-dawn tranquility when my serenity was rudely interrupted by that unmistakable, gassy serenade. (Two, if you count the flatulent 125cc commuter motorcycle that popped and wheezed in the opposite direction-manifold gasket issues was my formative thought).  

Motorcyclist around the next bend that familiar intestinal rumbling continued, and a small descent prompted me to engage a taller gear. Just as the Microshift bar con responded to my bidding, the serenity was broken by what I believed was the humous hitting home. Alas, that rumble in the jungle evolved into the thriller in Manilla...Yup, a chamois spoiling “shart” in modern parlance, which explained why I was unexpectedly moist and warm in said region, for the remaining 8 miles.  


Thankfully, I was spared further indignity and Samsung washing machine did an excellent clean up job, while I er, slunk off to the shower.   On the upside, Ursula had been cleaner than usual, thanks to primarily dry, windy conditions. I whipped the wheels out and treated the frameset to some Tru Tension Snow Foam.  


As the name implies, it’s a foaming waterless cleaner that contains a grime gobbling solvent component. This evaporates, leaving a silicone protectant barrier behind. This dismissed any residual grimy patina from the bottom bracket shell, fork legs, and rear triangle. The product in question contains a silicone component, which leaves a glossy protectant barrier behind.  


However, in my experience, fast buffing is required to avoid a streaky finish. An ideal opportunity to check brake pads for glazing, embedded contaminant, straddle wires and cables for fraying. As per usual, I gave the KMC X10.93 chain a quick measure, expecting to replace it with the X10.73 I had in stock but no, still dodging the .75 bin fodder mark. On went the new Alfine/Ryde dynohub wheel, ready for testing.  


Talking of which, I’ve decided to postpone the disc conversion until I’ve thoroughly tested the Alfine dynohub and/or when the existing Tektro cantilever pads wear sufficiently thin. The Alfine uses the centre lock disc mount, which is arguably superior to the six-bolt systems. They’re easier to centre and fit.  


No little screws to lose, just plug in your cassette tool, snug the lock-ring down to 40nm and done. I’ve never needed to re-tighten that belonging to the Shutter Precision SL9 dyno hub HALO EVURA & SHUTTER PRECISION SL9 DYNOHUB BUILD (sevendaycyclist.com), come to think of it.  Managed to lose the aero adaptor allowing seat stay mounting of my Cat Eye Viz 150, when I was whipping it off to recharge. Thankfully, I was able to retrieve and reunite with the main mount and not lost to a dark and inaccessible part of the garage.  


I switched to the Topeak Tailux 30 USB Rear Light, since that was fully juiced and has a super frugal flashing mode-good for nigh on 30hours. Not that the Lelumia is proving anything but reliable, I just prefer a secondary/backup in case something unexpected happen.  


While doing my weekly once-over, I also discovered the Torque 7 tool had loosened and separated within the Deore crankset, explaining the faint, phantom chatter that crept in across washboard tarmac. Easily retrieved using long, needle nose pliers, but could’ve been more problematic, had I been relying on it in the arse end of nowhere. Otherwise, I’m developing a strong fondness for the design. 


Far from the maddening crowd, alone with my thoughts and the wildlife, I have often contemplated my own journeys. Life is a game of chance. Good people do bad things, given specific circumstances and bad people can (and do) lead nice, comfortable, and rewarding lives. The notion that people “get theirs” may be comforting but isn’t necessarily so.  I’ve met a few church-going drug dealers in my time-one wanting me to courier drugs back from the Netherlands back in the mid-90s. I hope Adrian has been suitably generous when passing the collection box, him being a pillar of the community n' all...

Switch n' Save

 











Prevention is always more effective, and usually cheaper than cure. Regular inspection can stop a lot of issues before they start, especially during winter, when conditions are harsher and daylight hours shorter.  the KMC chain is still going strong and foils the chain checker’s .75 marker, and we’re way past the 1500mile mark, which may also add credence to Bike Medicine’s Claims that the Purple Extreme | cycling-not-racing (sevendaycyclist.com) extends drivetrain life.   


Some minor mudguard chatter piped up, causing me to give Ursula more generic midweek onceover. Stays nipped snug, I discovered a small but deep gash in the rear Schwalbe Marathon Mondial Double Defense TEST & REVIEW: SCHWALBE MARATHON MONDIAL TYRES (sevendaycyclist.com). This prompted me to switch to the Schwalbe Marathon GT 365 TESTED: SCHWALBE MARATHON GT 365 TYRES WINTER UPDATE (sevendaycyclist.com) 


Hefty, as I’ve established on numerous occasions but ultra-dependable and offering decent traction when the mercury is stubbornly refusing to creep above freezing and that hard frost is audible. I acquired two more Schwalbe Land Cruisers. One for the Ryde/Alfine wheel (that Mick Madgett built with speed and enviable expertise this week) and a higher spec Land Cruiser Plus replacing the Marathon Mondial. I fancied a more substantial puncture repelling belt at the rear. Still 50g lighter than the Marathon 365, too.  


In terms of genre, the Land Cruiser remind me of Specialized Crossroads (26x1.9) which served me well between 1999 and 2001. Traditionally, the mention of mixed terrain, or dual-purpose tyres were synonymous with worst of both worlds. Sure, the Specialized and the Land Cruiser aren’t going to rival a 1.5 slick on the tarmac or a crossed country tyre through more demanding forest trails.

 

Nonetheless, some 600 miles down the line, they’re proving capable mixed terrain rubber that will swoosh along quite nicely on the tarmac, give a compliant ride along pockmarked lanes and still deliver along moderate trails. WTB All Terrainasaurus are another I have fond memories of. These are also available in 26x1.95 but I was running a narrower, 1.5 (have a feeling they came up smaller, nearer to 1.4). Dirt cheap, quick, and dependable for my commutes around South London... 


Since Ursula was in the stand, I got busy with the Motorex Grease Spray and The Torque Covert 7 Crank tool, whipping out bottle boss, carrier and mudguard screws. Being steel, these were all given a shot before I delivered a stream into Ursula’s inner sanctum and the Kona Project 2, while I was at it.  


Spray greases are super convenient and quite versatile, refreshing those parts thicker waxy preserves cannot reach so readily. In a pinch, 10w/40, or less sophisticated semi-synthetic motor oils are easily found/scrounged, can be delivered via a syringe and will do much the same job, in a steel frameset.  I've also delivered some into the less accessible regions of my KA, since the wings are welded, not bolted in situ. Removal, say if needing to repair a sill is a lot more involved. Getting some greasy stuff into the sills will at the very least, slow the advances of corrosion in areas where it can flourish unnoticed. 


Chainsaw oil is another cheap, readily available substitute, which doubles as a reasonable chain lube. Again, apply via syringe and be ultra-disciplined with the clean-up, or chains will become a matted, gritty transmission gobbling mess.


Bib shorts are a less obvious choice for the darker months, save of course, for slaving away on the indoor trainer. However, I often ride with bib shorts beneath lighter old school Lycra when temperatures are middling. Strangely enough, I’ve been comfortable with budget dhb bib shorts and 20-year-old GT tights (which I retain a strange, some would say irrational attachment to) when the mercury is struggling to climb into single figures.


I’ve been similarly impressed with the Gecko Ankle Length Waterproof Socks GECKO ANKLE LENGTH WATERPROOF SOCKS | cycling-not-racing (sevendaycyclist.com) which, being thinner than their Calf Length Classic All Action Waterproof Socks means they’re a better fit with closer fitting road and mountain bike shoes. No sign of this ice age, the red top tabloids have been screaming about for several months...Maybe it’s a cunning metaphor for something else...The cost-of-living crisis, which is forcing an increasing number to decide between heating their homes or feeding themselves and their children. Or perhaps the present diplomatic situation surrounding Ukraine...
