Scottish model, Deviate Cycles, is trying into a brand new manufacturing technique for his or her line of excessive single-pivot mountain bikes. As we speak at Eurobike, we caught up with Deviate founders, Ben Jones and Chris Deverson, who’re wandering about with a titanium-lugged carbon tube body that may be a working prototype for the model’s first downcountry bike.
Deviate Downcountry Mountain Bike Prototype
Deviate Cycles’ downcountry prototype is a part of a growth sequence, the intention of which is to research the feasibility of bringing manufacture to the UK. Presently, the Claymore and Highlander bikes are constructed from an epoxy resin carbon fiber, and are manufactured in Asia – the place precisely in Asia, we don’t know. However, Ben and Chris foresee a future by which their mountain bike frames are manufactured in Scotland out of 3D printed titanium lugs and recyclable nylon-based thermoplastic tubing… at a value aggressive with the price of manufacturing a full carbon body in Asia.
How do they suggest to do that?
With the usage of a extra reasonably priced technique of 3D printing titanium. Certainly, chilly steel fusion of titanium, as carried out by Huhn Cycles, is cheaper than the laser-sintering technique employed by the million pound Renishaw machine you’d see at Atherton Bikes HQ. Apparently, the tools vital for chilly steel fusion of the light-weight materials is vastly extra reasonably priced.
The result’s a 3D printed lug that does have fairly a unique end to that of the Atherton Bikes lugs. And, their manufacturing is alleged to require so much much less post-processing. Much less post-processing means much less guide labour, and thus, a decreased value. Deviate hope to undertake this technique of manufacturing whereas providing frames at the same value to what they provide now. That’s, round $3,200 USD for a Claymore body and shock.
The pair admit they haven’t but hit that time with the price of manufacture, however they’re urgent on with growth as a result of the plan is engaging for a lot of different causes, too; particularly, the availability chain will probably be shortened to the purpose the place they’ll make to order, and there’s the improved sustainability of all of it with decreased delivery, and the end-of-life recycle-ability of most, if not all, of the body parts. Additionally, we’re instructed the titanium powder used to type the lugs is carbon-neutral, too.
What concerning the linkage?
Deviate is continuous its use of a excessive single-pivot suspension platform that delivers a 100% rearward rear axle path, however right here on the downcountry prototype it’s packaged just a little otherwise to the linkages we’ve seen from the Scottish model beforehand.
The place the longer-travel Claymore and Highlander II bikes have a decrease linkage positioned concentrically to the underside bracket, this downcountry prototype retains all the pieces north of the BB. Because the rear wheel is displaced, the decrease linkage extends because the strong rear triangle strikes again and upwards because it pivots about the primary pivot positioned round half manner up the seat tube. On this state of affairs, the shock is concurrently pushed from each ends as it’s sandwiched by the decrease rocker and the swingarm.
And, this being a high-pivot mountain bike, there may be an loafer pulley positioned close to the primary pivot to scale back the unfavourable results of chain progress.
We’re instructed it could possibly be many, a few years earlier than Deviate absolutely undertake this manufacturing technique, and so much will rely upon whether or not they can automate it to some extent the place the frames might be priced competitively towards Asia-made carbon frames. It’s presently undecided whether or not the Deviate downcountry bike will first materialize in titanium or full carbon. We’ll do our greatest to remain tuned on this one!
