Description

On-One's high speed, gravel adventure proof full carbon frameset is fully rigged for 3 bottles, rear rack and mudguards. With 650b, there's room for 48mm tyres so whether you're touring the outback or just the back-way home from work, The On-One Space Chicken won't hold you back.

Shimano GRX is Shimano's gravel specific groupset. Single ring and 11 speed wide ratio, all terrain gears for sequential simplicity. Tough Hollowtech alloy cranks for maximum strength and durability. Switchable rear mech stabiliser for efficient chain security durability. Grippier hoods and quiet, smoothly powerful hydraulic disc brakes.

Fulcrum Rapid Red 900 650b wheels are MTB tough for maximum fun. Large volume 650B tyres mean big fun on rougher trails. Quality sealed bearings to laugh at whatever mileage and weather you throw at them. Easy to set up tubeless for a smoother, puncture proofed ride..

Pedal choice is a personal thing. Most higher end bikes are expected to be ridden with clipless pedals. These are matched to cleats on the underside of your cycling shoes. There are a few standards of these, and most cyclists tend to stick with one standard across all their bikes. So, you don't need to buy multiple pairs of shoes! That's why Planet X don't sell bikes with pedals included. If you wish to add pedals to your order, simply select an option from the drop-down menu..

NOTE: Please make sure you check the size guide to order the correct size of this frame. If you are unsure please contact our Customer Service Department

Sizing Guide

Rider HeightSuggested Frame Size
5′5″ to 5′8″Small (51)

5′10″ to 6′2″ Large (57)
6'1″ to 6′4″ X-Large (60)

Sizing Notes

All frame size recommendations are approximate. A good fit will also depend on the correct choice of stem length, correct bike set-up for the rider and riding style.

Correct frame size choice can vary greatly with riders' torso length. If you have longer legs and a shorter torso, go for a slightly shorter stem. If you think you are borderline between sizes, and you have longer legs and a shorter torso, go for the smaller frame size. If you have shorter legs and a longer torso, go for the larger frame size to get the extra top tube length.

As the frame sizes increase, so does the length of the head tube. If you are inflexible or perhaps have a history of back problems, consider going for a larger frame size. This will increase the relative height of the handlebars making the position less “extreme”. The larger frame will also have a longer top tube, so you’ll need to compensate for this with a shorter stem.
