Codeine 27.5

ENDURO READY 27.5" BIKES

Overview

27.5 Wheeled Enduro Thoroughbred

27.5 Codeine Mountain bike

The Codeine 27.5 is built to smash the trails. With 27.5" MTB wheels and 160mm of travel up front, it's thirsty for Enduro-style epics. By combining a longer and slacker front end with more travel than the original Codeine, the all-new 27.5 model is ready to get rowdy. Sure-footed handling and bottomless feeling suspension are what you'll find here - a dream for those who love to descend at speed.

Designed specifically for a 1x drivetrain (single front ring), the Codeine 27.5 offers plenty of mud clearance through its short and wide chainstays. Combine this with SRAM's wide gear spread drivetrains and you get enviable climbing performance. The Codeine 27.5 is a true all-mountain bike equipped to rip up any terrain you find - the ideal best prescription for serious off-road adventures.

Metalworking Magic

Enduro Masterpiece

Created To Attack The Trail

The Codeine 27.5 is hand welded from our custom drawn and shaped 7005-T6 aluminium. Each tube is perfectly shaped to maximise strength and minimize weight to help provide you with the most stable platform to attack the trails.

Every Codeine 27.5 frame is aligned by hand post welding and only when we're absolutely happy with the alignment of each frame does it go for a final T6 heat treatment prior to receiving it's 3 coats of paint.

160mm Front / 150mm Rear Travel

Performance Tuned Travel

Bottomless Suspension Feel

The Codeine 27.5 has an extra 20mm of travel all round than the 29er. 160mm up front to soak up the hits from the trail so you can ride full tilt down the toughest tracks. 150mm of travel out back helps you track through the rough stuff with maximum traction at all times.

Unique Trail Eating Geometry

Summit And Plummet Design

Power To Climb, Confidence To Descend

At On-One we believe that you should earn the descents so the 27.5 Codeine has our Summit and Plummet geometry. A steep 72 degree seat tube angle places you over the pedals in prime pedalling territory, helping you to grind your way up the climbs.  When it comes to pointing the nose downwards a slacked out 65 degree head angle combines with our low BB position to you give you incredible stability at speed while out short chainstays help keep everything nimble in the twisty bits. The Codeine 27.5 is pure Enduro

Ultimate Drivetrain Simplicity

Fast Rolling Wheels

Easy Rolling And Reliability

27.5" wheels roll more easily over obstacles than smaller 26" wheels and are faster to accelerate than larger, heavier 29er wheels- they're the Goldilocks wheel size. Combining a 27.5" wheelset with the simplicity of a 1X drivetrain with its single front chainring and extended ratio rear cassette gives the Codeine a weight and performance advantage that is hard to beat. The extended lifespan and reliability of the 1X drivetrain is simply the icing on the cake.

Technology

1X Drivetrain

1X Drivetrain

The Codeine is designed for a 1X drivetrain. A single front chain ring paired up with a wide ratio cassette gives you a huge gear range, lightens your bike and banishes dropped chains.

Tapered Headtube

Tapered Headtube

An oversized tapered headtube increases bearing surface area where you need it most. The larger tube area also helps to make a stiffer front triangle for improved steering accuracy.

7075-T6

7075-T6

Not your run of the mill alloy frame. We use 7005 to form the complex, curvaceous tube shapes of the Codeine. It's the perfect metal for making a serious all mountain frameset. 

160mm of  front travel soaks up all the big hits, while 150mm of rear suspension keeps you firmly glued to the trail
