Phantom Squeaks & SQR

There’s a natural rhythm  to our machines, and we quickly cultivate an ear for anything different. You know the ones. Intermittent clicks, squeaks, rattles that induce in-the-saddle diagnostics. 

Dancing on the pedals, while climbing to rule out a poorly pedal, grumbling bottom bracket, loose crank…No, Hmmm, hope that’s not the free/hub…Stop, waggle, probe. Nothing… UN55 bottom bracket seemed fine, bars snug, ditto mudguard hardware. 

Every few rotations of the crank, came a dull, faint clicking. Loose seat post clamp? Subtle bouncing on the saddle, dismissed this idea. Coasting suggested the Deore hub wasn’t heading for oblivion, either-mercifully. 

Final climb reduced potential culprits to pedal, or crank. Sure enough, introducing my workshop length 8mm into the left-hand arm, revealed the bolt was a little loose-hence the creak. I was four complete turns before it wound drum tight. 

This also prompted a quick tweak of cockpit, saddle and mudguard fasteners. Oh, and a pedal swap for good measure. Celebrations proved a little previous. The following day, we were battling high winds, when click, click…Bong! Yep, the ultra-reliable UN55 cartridge bottom bracket, had finally got the grumbles.   

Ironically enough, this Cyclo 20 function multi tool arrived, shortly after. There’s a temptation to suggest more is better, when it comes to functions. However, usability is another big factor, especially when tackling adjustments/repairs by the road and trail side. 

These feature long tool bits, great for torque and/or stubborn fasteners, there’s a chain tool, and integral tyre lever, should you forget to pack one. 

I’m pleased to note this features a 15mm wrench, for solid axles. However, sometimes, smaller S shaped keys are more convenient for tighter spaces. Including mudguard bridge bolts, saddle clamp fasteners etc. 

Once upon a time, panniers were my default for day rides, touring, commuting and indeed, tag along tugging. In the latter contexts, the attraction is obvious. Tools, spare tubes, spare clothes, cakes, big “F*ck off” lock. Bananas, cake and other snacks are easily carried.

Room for extra clothes, should temperature and weather generally change, one way, or the other. Oh, and I could always swing by the supermarket and collect some basics, en route home. 

Not everyone wants to be encumbered by a rack and I’ve become a real fan of Carradice’s SQR system which allows compatible luggage to be whipped on/off. A ten-kilo maximum payload is great for day rides, Audax, commuting and possibly, weekend touring. 

I’ve run their cotton duck SQR tour, on and off, for 18 years. So, I was delighted to receive their Carradry SQR bag. This is an expandable system (14-18.5 litres), which on paper, should rival a small/medium sized pannier.  

One of the main advantages to this system, over a pannier, when commuting in congested traffic, is the ability to sneak through gaps more readily. Messenger bags, rucksacks and similar rider-mounted luggage can be a serious boon. Especially for hauling laptops, folders and similar valuables/delicates and for short distances. However, I prefer bikes to do the carrying. 

While the mighty Cotton Duck is certainly waterproof, it’s a little trickier to wipe clean (even though the undersides feature a protective laminate, to protect the base from mucky water). The sonically welded fabric, only requires a damp-cloth onceover. The other thing I love about the SQR system is its rigidity. 

Climb out of the saddle and it doesn’t bob around like the proverbial playful Lab.  The one problem with this system, in my experience is its incompatible with post mounted trailer/tagalong. 

Although frankly, I’d always opt for a chainstay mounted hitch, their lower centre of gravity has much less impact upon the bike’s handling. 

About posts; I’d only tether anything of this genre, to metal models. Oh, and you also need a healthy amount of seat post showing, for the SQR hitch. I’ve had to move this Lightrider PHASE light to the seatstay https://www.sevendaycyclist.com/lightrider-phase-rear-light

Wedge packs, such as this Axiom Grand Fondo are my limit, for carbon composites. Afterall, there’s a reason why we use gripper pastes and lower torque, when fitting.  Right, apparently John’s finished the Halo wheel build, so I'm off to have a look...

Sorting Shot Bearings

Amid the chaos of wholly unnecessary central heating oil tank replacement (resultant from a neighbour’s vitriolic refusal to accept two independent, qualified reports that the old unit was completely sound and fit for purpose); one's freelance canoe has been paddled with renewed vigour and seemingly positive results. Aside from the usual projects/collaborations, I’ve been weaving through the web's many strands of opportunity, albeit slightly undecided about some.

Anything with the “homeworking” tag targeted specifically at women sets my senses on red alert. For decades this was a euphemism for sweated, piece rate labour that often cost participants more money to acquire the raw materials than they actually made-£5 per thousand envelopes being one of the most commonly advertised lures that springs to mind. 

This appears to have crossed into creative, skilled vocations in recent years- $5 for 1,000 word feature ring any bells among fellow freelancers? Frankly, anyone foolish enough to plunder these depths i.e. willingly compete in such races to the bottom will find precious little sympathy from this corner.  

While shifting half a tonne of new central heating receptacle through the side gate and to its newly set concrete plinth, “Uncle” Benny happened to mention one of his bike’s fit n’ forget square taper bottom brackets had finally turned sloppy, so I agreed to supply and fit a cheap but fairly cheerful Shimano replacement. In this instance we settled upon the Japanese giant's basic UN26 complete with composite sleeves and solid steel axle-£7 inc postage. Removing the resident "Power pro" unit proved less taxing than I thought given a brief blast of penetrant spray inside the seat tube and using sheer leverage from Lezyne's CNC rod.

Despite giving the incoming unit’s threaded sections a liberal slathering of ceramic polymer grease and using precision tooling, these components are decidedly soft and very easily stripped-overcome by applying gentle pulses of super invasive penetrant spray while surreptitiously winding it fully home in gentle bursts.   

No sooner had we everything reinstated and double checked, it became apparent that his entry level road bike’s unit had succumbed to the same fate despite only a handful of rides! Given our experience with the UN26, he’s requested I supply and fit the UN55, whose superior bearings, seals and hollow axle should amass much higher mileages before singing that familiar swansong.

Staying with square tapers, this rather fetching System EX crankset has replaced the cheap but decidedly charming Stronglight ST55. 44 teeth maintain the road sensible 77 inch gearing, eliminating risk of spinning out on the flat or straining on moderate climbs.46/48t are the preserve of track or pancake flat TTs, though supply of 130 BCD fare is reasonable should wear or whim dictate.

At a glance 669g is fairly beefy-less than some super stiff hot forged track models but in keeping with other sub £60 fare and 170mm arms will suit production fixers, conversions or indeed some single/hub gear builds with lower bottom bracket heights since there’s less risk of grounding out when cornering hard.  

Mirror polished finishes are vastly superior to paint and this one should resist the salt monster’s advances for several seasons-longer fed periodic helpings of decent quality polymer car polish. In common with others in this class , detailing's a little workman-like around the inner spider but this isn’t glaringly obvious/likely to prove a deal breaker on trainers/club builds. 

Initial impressions are extremely favourable with excellent power transfer and nominal whip under sprinting or climbing efforts. However, we’re only 50 in to a 300mile plus evaluation for a new consumer focused title, so said remarks must be regarded as formative at this stage.

Rummaging through my spares drawer resurrected these low-profile, dual-sided shop branded Ritchey WCS homages for more convenient getaways and further improved ground clearance.They’re actually rather well made by FTP-another Taiwanese marque, boasting nicely machined, powder coated aluminium bodies, super reliable Cro-moly axles turning on remarkably smooth cartridge bearings. 

Ironically (and this seems true of other patterns) while perfectly accommodating of genuine Shimano cleats, they seem happiest with VP, Wellgo, Btwin and indeed Exustar! On that note, I’m off to pedal my wares and invest further energies into matters marketing/promotional.         

  

Bearing Up

It was only a matter of time before the Univega’s UN52 finally succumbed to slop. Mercifully its swansong commenced at the close of a fifty mile saunter, some sixty metres from Stenningrad.

Largely superseded by external cup designs, 8,000 miles plus isn’t outlandish from these venerable square tapers so long as jet-washing and similarly destructive habits are avoided. 

However, as component designs evolve, or indeed fall from vogue; supplies of older mid-range stuff often dwindle, leaving the market polarised between bargain basement and top drawer.     

Within two minutes of powering up the laptop and entering “68x113 square taper” into Google’s search bar, we’d scored a brand new, unboxed UN55 for the princely sum of £12.50 including postage! I’d been fishing for an XT grade UN72 but these have become rarer than hens’ teeth and I didn’t fancy playing the ebay lottery.

Without taking a grinder to their shells, aluminium alloy cups and hollow axles separate the 50s, saving a few grams without sacrificing strength; though avoid lithium based greases when speeding them inside ferrous frames, or risk the joy of seizures many miles hence.

Less than 48 hours after adding to cart, transplant surgery proved very straightforward given the existing unit was introduced with lashings of stout ceramic prep, complimented by copious quantities of home brewed corrosion inhibitor. Curiously enough, the UN55 has also reduced the Q-factor slightly but this is pretty academic on a tubby tourer. Now for some self-extracting M8 crank bolts methinks…
