On-One’s painkilling Codeine: a long-travel full suspension 29er
Today’s one of those days when we hear about all sorts of cool stuff at once!
Developed while designer Brant was recovering from a back injury (and on painkillers) is On-One’s new Codeine full suspension bike. It’s the first full susser that we’ve seen from the British consumer-direct brand (and Titus stablemates) since the Growler and has some interesting numbers that make it look like a pretty good time: 29in wheels, short 44mm chainstays, and a slack 67 degree head angle. Travel should be 128mm at the back and a big 140-160mm at the front. Target weight is right around 7lb and the price will undoubtedly be reasonable. According to On-One’s US office, Brant’s expecting his sample tomorrow and production hasn’t been scheduled. Until then, we’ll have to settle for the backstory (after the break)…
I designed it about a year ago, whilst suffering a back injury and as a result on lots of Codeine painkillers. It was rather an odd time as the drugs made me concentrate very hard on certain things and ignore others, which led to a really interesting CAD design session where I got very involved in tiny details that I’ve never studied before, and was completely happy about going through tiny iterative revisions of linkages and positions to get things exactly how I wanted them.
It also was a bit wierd as I decided that I didn’t need a front mech any more, but then having finished the drawing talked to a few people who thought that was stupid, so the project was shelved, but then brought back to life when SRAM’s XX1 came around as I figured that would trickle down eventually and we’d better crack on with it.
It’s a single pivot with a linkage driven shock. I like doing bikes that way. The singlepivot actually allows a shorter chainstay length than a Horst Link for the same travel – the Horst Link bike seemed to pull the rear wheel in more throughout the travel so the rear wheel hit the seat tube sooner. I did this using the Linkage software from Bikechecker and then throwing the output from that into Cadintosh which is a very basic 2D drafting package for my mac. From that I pass 2d to Taiwan, who then 3d it, and we fire things around a bit and it’s all done.
The 16in model Ed’s holding is currently being bashed about. We’ve got some tidying up to do before production, some weight saving, some modifications, but the basic geometry and features are working really well.
Headline numbers that people care about:-
Oh yeah – it’s a 29er. 140-160mm fork, 128mm rear, 67deg head angle, 35mm BB drop, 440mm chainstays (that’s 4mm shorter than our Scandal 29er hardtail!). Current frame weight 7.45lb. Planned frame weight 7lb.
ISCG05, Dropper compatible, 142 (will be, is 135mm right now).
No production date is planned currently.
