Eurobike 2011: Bionicon goes coil sprung, plus hyperextension explained

Video

Roger from Bionicon shows us the new Alva 180, which like all the bikes in the Bionicon range, features on-the-fly fully adjustable travel and geometry.

Two models are available – the coil sprung Alva Coil 180 (a first for Bionicon) and the lighter weight Alva Air 180. We also get an explanation of the Hyperextension system, which mechanically increases the shock rate when in the climbing position to stiffen the suspension without having to use any platform damping.

We also get to see their new minimalism chain retention system the C-Guide, which as well as being super neat, will fit almost any bike…

Is that named after the small Clackmannanshire town or Tony?

I’ve got that chain guide, my LBS here in CH gave me one to test for him. It’s pretty good, very quiet, does the job, but only issue is that in really claggy mud the wee hole can get a bit blocked, but I guess that happens to all chain devices in serious mud. sorry to focus on a 5€ part rather then the bikes! Coil one looks sweet!

Did he say prevents chanisuck? Did he, DID HE! I NEED TO KNOW!
Sorry, I would have given a kidney for one of them in Kielder, or at Ruthin last year, or the year before, or on any long ride when the weather is crappy. Not sure how it will prevent chainsuck though…

Tracker1972 – you can zip-tie the new C-Guide to your chainstay instead of mounting it on the cable…
