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.
