Harvest Festival








 

No, not that one…After a week’s postal drought, a blizzard of kit arrived, including the Redshift Shockstop Suspension Stem www.redshiftsports.com I referred to, a few entries back.

Unsurprisingly, it’s infinitely more sophisticated than the Girvin Flex stem that divided opinion, back in the day (but one I was rather fond of). More refined engineering and working to closer tolerances, set up, is perhaps, predictably, a little more involved.

Given this precision and depending on rider weight, elastomers need to be swapped over and pre-load carefully reset. Not the sort of installation you’d attempt, 20 minutes before a big ride.

On paper, my Holdsworth might seem an unusual test rig. However, the shock stop is also intended for tarmac biased riding and the weight penalty, compared with a traditional 7005/6061 unit, is only around 80g.

As I’ve mentioned before, the frameset’s thin, steel tubes and carbon composite fork blades, are synonymous with compliance. However, the steerer is aluminium alloy and front end can feel unexpectedly direct, over washboard surfaces. My favourite 1in7 descent being a case in point.  

Ison Distribution www.ison-distribution.com sent me these rather fetching Genetic CX cantilevers for testing. I’ve reviewed several Genetic products, from pedals to seat posts, over the years, and have been consistently impressed, by the brands’ bang-for buck ratio.

Despite discs’ dominance, there’s a lot to be said in favour of the humble cantilever. Lightweight, a well-honed unit has adequate mechanical bite, to halt 115kilos-comfortably.
These are CNC-machined aluminium. The braced design, we’re told is designed to eradicate flex. 

Standards of finish are very high, relative to the asking price and polished finishes always keep their looks. Albeit with the occasional waxing, or buff with a polishing cloth and product, such as Crankalicious Mayo Jaune. https://www.sevendaycyclist.com/crankalicious-mayo-jaune-intensive-  

The Genetic were trickier to set up, with my Univega’s shallower reach Microshift brifters, which is historically, the case, with any wide arm design. M System patterns and models, such as, these Avid Shorty 4, are pretty much plug n’ play.  Crucially, I have the tubby 
tourer’s braking back up to scratch now.    

Elsewhere, I’ve switched my winter/trainers perch from the likeable 14mm wide BBB Echelon saddle, to titanium railed Brooks Swift homage. Motivations for this, will become obvious, further down the line.

However, its butt bespoke and some additional “spring” is welcomed along the lanes. Especially, since I’ve forgone the Cane Creek Thudbuster ST https://www.sevendaycyclist.com/cane-creek-thudbuster-suspensuin-se   in favour of the more tarmac traditional Genetic Syngenic https://www.sevendaycyclist.com/genetic-syngenic-seatpost .
Despite warnings of apocalyptic weather fronts, temperatures remain in the high teens/early twenties. 

No call for substituting shorts and summer jerseys for something more substantial (although summer kit is easily extended through autumn, with Lycra arm and leg warmers).
Talking of which, I’ve been suitably pleased by the Tenn GC Eurosport range https://www.sevendaycyclist.com/tenn  https://www.sevendaycyclist.com/tenn-global-eurosport

We are being approached with winter ranges, including some from Stolen goat www.stolengoat.com , which is really nice.

The 29th marks the tenth year of this blog and has me reflecting on my motivations behind it. Its conception originated with the acquisition, and restoration of a certain orphaned frameset-hence the title.

However, other cycling related projects and concepts/product testing soon crept in. Occasionally it has lapped at social commentary and indeed, some personal shorelines. There’s a lot more to riding, than components and equipment, which make everything go, stop and handle in correct proportion. Yes, I am including the rider, in this equation.

Two wheels, with and without engines are extremely practical, everyday vehicles for a small planet but long, steady miles are very conducive to deeply reflective states. Often, I contemplate the journeys along life’s highways and my wrong turns on its roundabouts.

I’ve been brutally penalised for some mistakes on the one hand and I am acutely aware of a controlled rage within me. Conversely, I have a responsibility to myself and others, to learn from and channel these experiences/emotions positively.

Similarly, some unexpected detours have resulted in serendipitous successes. On that note I’ll end with Steve’s review of Surly’s Ted Trailer. With a maximum payload of 300lbs, its ideal for those of us carrying big, bulky loads, of a physical nature.  https://www.sevendaycyclist.com/surly-ted-trailer

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.
