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.

Making Contact









Contact points are probably the most personal and subjective components. Redshift sports are sending us their Shock Stop suspension stem. Like most things, its not a new concept. https://redshiftsports.com/shockstop-suspension-stem

Redshift sports are a group of mechanical engineers and this is apparent in their meticulous approach to research and development. Other components include their Switch system. https://redshiftsports.com/systems

These include a quick-release aerobar and a dual position seat post, which can be adjusted for an aero/road stance to suit conditions. A very appealing idea, allowing a road bike to double as a TT machine with minimal faff.     

Those of us who spent the early 90s blasting along the trails, will doubtless draw parallels between this, and the Girvin Flex stem. I was very fond of my Flex stem (not to mention the 1990 Kona Lava dome it was fitted to).

Though it offers between 10 and 20mm of movement, the shock stop is aimed at the thinner tyre Gravel/Cross/Adventure faithful. The system is reckoned to be maintenance free.

Elastomers are the common link between the two designs. The Girvin wears it’s with pride, the Redshift’s are internal (primarily because it’s an Ahead system). Contact points can also fool you into thinking it’s the best/worst change you’ve made.

I’ll reserve judgement, temper my excitement and reflect after 400miles, or so.  Several hundred miles hence and I formed some definite opinions, regarding the Soma Highway1 handlebars. https://www.sevendaycyclist.com/soma-highway-1-handlebars  The change of stance is exactly what I was seeking. Despite the Holdsworth’s pencil thin steel tubes and carbon fork, the front end can feel very direct, when tackling washboard surfaces, especially at speed.  

I have also been impressed by this Genetic seat post. Some have drawn parallels between this, and Thomson units. There are clearly nods in the latter’s direction and these really appeal to me aesthetically.

CNC machined 7075 aluminium alloy is extremely durable and so far, the anodized finish is extremely pleasing, aesthetically and better than I’ve come to expect from this price point. https://www.sevendaycyclist.com/genetic-syngenic-seatpost

Ours was the road biased 300mm, plenty long enough for my ‘cross cum gravel biased fixed. There is a 400mm version, arguably better suited to mountain bikes and/or taller folks, riding smaller compact geometry road framesets. For the time being, it’ll stay, and I’ve earmarked the mighty Thudbuster https://www.sevendaycyclist.com/post-modernism  for project Dawes.

Staying with contact, tyres are our first point, with terra firma. A more changeable weather front has presented an ideal opportunity to really test the Vee Tire Co City Cruz. https://www.sevendaycyclist.com/vee-tire-co-city-cruz-tyres

Without giving too much away, it’s a dependable tyre, well suited to commuting, general riding and winter duties. The sort ideally suited to bikes that serve as trailer/tagalong tugs.
In my experience, children can really enjoy winter rides (so long as the temperature’s not too extreme). 

Properly dressed and at a steady tempo +3/5 is fine fir them. However, time spent fixing a flat (s) can quickly lead to chill, misery and negative perceptions of riding.

On the flip side, there’s a weight penalty. In this instance, 1600g to a bike, which did give said fixed, a slightly stodgy feel, so having done 400miles and reached some definite conclusions, I’ve reverted to the Soma Fabrications Super Vitesse EX. A fast and very supple tyre, which tip the scales at a feathery 566g (700x33c) https://www.sevendaycyclist.com/soma-fabrications-vitesse

Now things tend to expire in threes. First, my Cat Eye Rapid X rear light expired, refused to power up, or accept charge. John Moss had a look on my behalf and said the switch had mysteriously combusted, consuming the PCB track in its wake.

Bin fodder, essentially. Next to expire was my ‘cross inspired fixed’s rear hub. Thankfully, I was only half a mile from home, the wheel was literally dancing the samba. I headed home and swapped it for the deep section Halo hoop.


Then I noticed its sidewall had developed a massive bulge. Back to base, Soma Fabrication super Vitesse EX transferred, it was time to disappear, along the backroads. So this configuration stays, until I make time, to strip and investigate further.
