OnOneCodeine-9199On-One Codeine 29er // Sram X01 // Pike // Reverb // CCDB


Today On-One is releasing the Codeine 29er. A true On-One suspension bike, made in our own unique way, designed from a piece of paper and crafted to be the bike we want to ride, because nobody made one that was quite right. The Codeine is available as a frame with rear shock and as a complete bike with SRAM’s X01 groupset. It’s a 29er, it’s got 140mm of front travel and 130mm of rear travel, it runs a single chainring up to 34 teeth, big tyres and it’s a whole heap of fun to ride.

On-One-Codeine---Studio-01A big hitting 29er with pop and fun. Fitting big wheels, with clearance to run big tyres – even our 2.4in Chunky Monkeys – into the space normally occupied by 26in ones. So that’s 440mm chainstays – shorter than our Scandal hardtail, but with 130mm of rear travel to keep you out of trouble. Up front a 140mm travel Rock Shox Pike scythes its way through the rockiest lines around – this bike was made for the technology that’s now available to get the most from the big wheels. A single chainring drivetrain, those Pike’s with their huge stanchions allowing amazing tracking.

“This is the bike we always wanted, so we made it ourselves.”
Brant Richards – Head of Design

Who’s It For?
Trail riders. Gravity Enduro racers. People who like hitting things hard and fast, or who want a bike that’s capable of that. You can ride it on more or less any terrain – and we have.

No Front Mech
That’s right – you can’t run a front mech. Why? Because removing the front mech enabled us to design the bike to ride the way we want, without compromises. At the time of original design, we were all riding around with chain guides, but thanks to the innovation of SRAM we’re delighted to offer it with their X01 drivetrain, offering 1×11 with more than enough gears to get you through and over the biggest hills around, all on a chain-guide-free system.OnOneCodeine-9525

What’s it Made From?
The chassis is designed to be stiff and durable, and yet weighs under 7lb. Hand welded from custom formed 7005-T6 aluminium tubing, with CNC machined fitments, rolling element bearings, and torx bolts on all fittings. With development from our team, using construction techniques that our team have used on enduro, downhill and trail bikes over the last decade. It’s all here in the Codeine, tuned and fettled to give you an amazing ride. We’re confident and very happy with the durability. It’s not an XC race bike, and the CCDB shock isn’t the lightest, but when push comes to shove, having a chassis that’s as solid as this – “The stiffest FS bike I’ve ridden” – handling excels with superior tracking. Benchmarked against every other trail bike we’ve tested, this is one of the best. We’ve had people refuse to give them back during testing. It’s been amazing.

Geometry is “Winch and Plummet”. Steep seat angle – 74degrees – to get the power down and be in an efficient pedalling position, with a good reach to the bars. BB is low enough to be fun, at 35mm below centre, but not perilously so. Head angle is matched by wheelbase and chainstay length – 440mm – to give the perfect dynamic handling up or down. Want a number? It’s 67.5degrees. We recommend the shorter style of stem, from 35-55mm and 720-780mm bars.
