Before you buy
- One frame size, XL: for riders about 188–196 cm tall. Check the geometry below.
- Used condition: this is a second-hand bike. Photos on this page show the model; message us for photos of this one.
- Wide-range 1x gearing: a single 40T chainring with an 11–48T cassette, one shifter to think about.
- Ready for bags and mudguards: rack, mudguard and bottle mounts on the frame.
What makes it work
Microshift Advent X 1×10
A 40T chainring and an 11–48T cassette give a low climbing gear for steep gravel and enough top end for the road, with no front derailleur to maintain.
Flared drop bar
A 16° flared alloy bar gives more control on loose surfaces, with the Advent X shift-brake levers on the hoods.
Carbon fork, thru-axles
A carbon rigid fork with 12 mm thru-axles front and rear keeps the bike stiff and precise; Tektro MD-C550 mechanical discs on 160 mm rotors.
Room for 45 mm tyres
Fitted with Vee Tire Rail Frenzy 700×40 tyres on 23 mm (internal) double-wall rims, both tubeless compatible, with clearance up to 45 mm.
