Frazzled Freehub?












 


There we were, minding our own business, bimbling along the lanes when the glitch became a low grumble. Ursula’s chain began jumping and the freehub began to lock up when I attempted to freewheel. Yes, the Halo Spin Doctor’s freehub was protesting 8 miles from home. No river riding, Jet washing, or similar abuse and I’d only done a few weeks riding since it was replaced in December.  

Mercifully, my default constant cadence, developed through many years riding fixed meant we could scoot back at 12-14mph. Pedestrian perhaps but infinitely preferable to walking home. Switching to XT/Ryde wheel with recently upgraded bearings, loaded with Juice Lubes Bearing Juice solved the immediate issue. However, it left me with something of a conundrum. 

An email and subsequent telephone chat with Ison-Distribution suggested it could just be wet, gritty stuff creeping inside along the lanes. I also learned the unit has a grease port, something I consider a godsend for easy maintenance and long component life. Sure, you’ll still need to strip and inspect bearings, races etc but it means they’ll have plenty of lubrication and are protected from the elements in-between. On the advice of Ison Distibution’s MD, I pumped grease into the freehub’s port until some brown gooey stuff bled out. Cleaned up and dropped some middleweight wet lube into the port.    

Then my mind went into overdrive... 

I could always retrieve the lowlier Deore- a decent enough hub but the seals and other components aren’t as you’d expect, to the same standard. Given the mileage and four seasons’ service involved, I’d be better served by the XT, and it would ultimately work out cheaper, long term. There were some interesting hubs but too pricey for a gamble, especially on the spares front. No rush... 

The fixed’s Un300 square taper bottom bracket is still turning away smoothly three years on. Testament to it (and the UN52 and 55 predecessors) build quality. I’m not the only rider who has returned nigh on 10,000 miles (about 16093.44 km) before they’ve turned sloppy, or grumbly. For context, while some of the patterns have served me well, they’ve hit the bin at 6,000 miles (about 9656.06 km). I may well go for this Genetic Cromozone Cromozone Sealed BB | Ison Distribution (ison-distribution.com next time.  

To lubes. The Blub ceramic is supposedly unsuitable for damp to wet conditions, but I’ve been pleasantly surprised by how it stayed put, despite being exposed to wet, greasy roads, not to mention blasted with deep, dodgy puddle water.  

I was surprised to find Ursula’s left Microshift bar con rotating in the bar ends. An easy fix- simply a matter of popping in a 4mm Allen key, separating the lever from mount, introducing a 5mm into the expander wedge and turning counter-clockwise.  

An opportunity to use this Muc Off 17in1 multi tool, which I’d received for testing. It’s a compact model with 17 functions and thus far, only a few, minor compromises have revealed themselves. When choosing multi tools, in my experience much will depend on your bikes, their age and genre.  

Compact models such as the Muc Off work best on contemporary bikes, including, but not restricted to smaller framesets. Multi tools are designed for quick tune ups and get out of a jam repairs, not workshop duties.  

However, tourists, or those on group rides might find Topeak’s Alien, or this Passport CDWPASSPORT CDW MULTITOOL | cycling-not-racing (sevendaycyclist.com) a better bet. Talking of touring, functions such as spoke keys tend to be a little basic, and not the nicest to use, so you’re better served packing a dedicated key.  

I’d also suggest packing a separate, long-ish  L shaped key for recessed fasteners, such as those found on brake levers/brifters and of course, any specialist tooling for your bike, tagalong, trailer etc. Same goes for tyre levers, and applies to the Alien and CDW, although these are the better of the grouping.  

Strangely enough, while the ergonomics of more expensive standalone composite levers mean they’re nicer to use, some of the most dependable models are the bargain basement nylon types usually found in puncture repair kit bundles. Thorn Cycles 20 function Multi Tool comes complete with a Rohloff compatible bit. Mine still serves me well, although 16 years down the line, corrosion has made itself known in places. Last lube biased mention for this entry, my review of Muc-Off MO94 https://www.sevendaycyclist.com/muc-off-mo94-multi-use-spray  

The Leatt Jacket MTB Endurance 2.0 has become my default, given its lightweight, yet highly windproof, water-repelling and quick wicking properties. The perforated back and arm panels ensure a steady supply of cooling air, while keeping the chill and moderate showery rains at bay and it's so light, I’m only noticing its positive qualities.  

It also packs small, taking up minimal space in bike luggage, although it will certainly fill a jersey pocket. I’ve been alternating between bib long and bib knickers, given the season but I’m also looking forward to putting the Endurance Bib shorts through their paces once the temperatures get milder.  

There’s the usual detailing I’d expect from a premium garment- mesh bibs and braces, SPF50+ UV protection and a 4-layer Italian chamois pad, reckoned good for 7 hours of XC trail riding, which also bodes well for long, steady road miles, too.  

Pockets have become an increasingly common sight on bib shorts, especially those geared towards gravel and mountain biking audiences. Madison’s Roam Madison Roam Men's Cargo Bib Shorts | cycling-not-racing (sevendaycyclist.com) being prime examples, although theirs is designed to port bigger items including phones. Gloves and other things you might want easy access to. Leatt has suggested theirs is intended for a communication radio, but I think it’s a good bet for energy bars and other essentials.  

I could don Lycra knee warmers, since these are designed to extend a garments wearability, say in autumn, or early spring, where the weather can switch from warm sun to chill rain at the drop of a hat. However, I appreciate their benefits. Those I’ve tested tend to slowly work their way down, exposing skin, while being annoying, into the bargain.   Could wear them beneath messenger knickers, though…Watch this space.

Reflections & Relentless Rain











 Water, Water Everywhere but Not a Drop to Drink. Flooding has been this winter’s narrative and the lack of flood defences here in the UK would seem to be making matters worse. However, the less extreme ends of this are great for assessing the capabilities (and sometimes shortcomings) of everything.  

From waterproof, breathable clothing to mudguards, waxes, detailing products, bike washes, lubes, and of course, electricals. Leatt has sent me their Endurance 2.0 Jacket, which is aimed at cross-county mtb/gravel audiences but in my experience, makes the transition to general road duties very well.   

The jacket is a “super lightweight” model that packs down very compactly. Leatt reckons inside a jersey pocket, and I’d broadly agree, depending on how large your pocket is. No issues with the old-school, deep terrace typeIt’s a Nylon/Elastane “rip-stop” weave that forgoes a laminate for improved ventilation and features a DWR (Durable water repelling) windproof and stain-resistant outer shell. Knitted panels also feature knitted paneling in the back and panels for improved ventilation. 

The former also features a poacher’s type rear pocket. Me being me, I would’ve preferred a breast pocket too, for a compact camera etc. However, it’s a feathery, racy, close-fitting cut for minimal flutter and this second pocket with cargo would pull, thus impairing the fit etc. That shouldn’t be read as only being suitable for summer weight/long-sleeved jerseys. I’m pleased to report ours is roomy enough for the winter-weight jersey cum jacket genre too.   

I’ve gone for the blue but black and rust are the alternatives. The zipper is also waterproof, although I would’ve preferred a bigger tag, even allowing for my not-so-dextrous dominant index finger. I’ve done my usual, cable tie zipper tag extension, solving said problem.   

Packable garments are arguably the most practical options for changeable conditions, although I’m still a big fan of the 2.5-layer laminate type when it’s predictably wet and indeed cold. Talking of which, I also received some more lubes.  

This time from Blub’s range- a ceramic and a wax, which are cleaner running preps designed for drier weather. Obviously, it's most important to test them in the conditions for which they were designed. However, I am also interested to see how products like lubes behave in wider contexts. After all, conditions can change throughout a ride. How practical is a lube to reapply? Does it wash away, how good are its corrosion-inhibiting properties? How much grime does it attract etc.   

One of the very appealing features of these two is their rapid curing times- allegedly two minutes apiece for both, which is on paper as practical as you’re likely to find. Seems a little longer in practice. That said; I’ve been applying in 2/3 degrees. Yes, I know there are still pour-and-go formulas but even after you’ve drizzled them into the chain’s inner sanctum, you’re still needing to wipe away the excess before hopping on and scooting offI’ve left the fixed and Ursula’s curing for a day, primarily since I applied having purged their drivetrains and given both bikes a seriously good sudsy bucket wash and wax.  

One thing led to another, and I whipped this 28mm Schwalbe One 365 up frontAll weather/ al conditions tyres are a big ask and to some extent, there’s always an element of compromise somewhere. In my experience, with lighter, swifter tyres it tends to be puncture resistance.  

The Schwalbe weigh in at 332g apiece, less than half the weight of The Pirelli Angel ST Urban Tyres Pirelli Angel DT Urban Tyre | cycling-not-racing (sevendaycyclist.com) and indeed, the super dependable Kenda Kwick Journey KS Plus KENDA KWICK JOURNEY TYRES | cycling-not-racing (sevendaycyclist.com) . However, these Vittoria Rubino Pro Control Graphene 2.0 Vittoria Rubino Pro Control Graphene 2.0 | cycling-not-racing (sevendaycyclist.com) are a much closer comparator and 5g apiece heavier. Will be interesting to see how the Schwalbe perform across the board and compared with the Vittoria and to a lesser degree, the Maxxis Refuse 700x32c 60 TPI TR Folding Maxx Shield Tyres MAXXIS REFUSE TR FOLDING TYRE | cycling-not-racing (sevendaycyclist.com) 

I’ve also been further contemplating the benefits of hub transmissions and bikes built around them. Genesis Day One employs a double-butted aluminium alloy frame and Cro-moly fork and is built around the humble 8-speed Nexus hub. Cable-operated discs might lack the low maintenance bite of hydraulics but are easy to service and repair.  

Budget but a practical workhorse cum commuter. Nice enough but not so pretty you’re petrified by the thought of tethering it to hardy street furniture with a decently stout “fuck off” lock. Long story short, I’d be interested in racking up some proper miles on one.  

Another enticement, given the flooding and generally adverse conditions are hub dynamos that can be serviced “in the field”.  By that, I really mean models that can be stripped, bearings replaced and regreased without going back to the factory. Interestingly one side of the Alfine hub dynamo Shimano Alfine UR700 Hub Dynamo | cycling-not-racing (sevendaycyclist.com) can be accessed and the bearings replaced.  

While the SP series of hubs have been impressive despite some extreme and persistently wet conditions, I’m tempted by the KASI FS DynaCoil CL/D6 units which are designed to be opened using a 36mm headset spanner. I’ve had 20,000 miles plus from the PD8 before the sealed bearings got sloppy. However, given the miles Ursula and fixed gear trainer rack up in foul weather, the ability to strip, clean, and rebuild the hub, without dismantling the wheel is a definite draw
