Description
The Rondo Mutt ST 650b Disc Gravel Bike is the ideal companion for the longest of adventures across all roads, tracks and paths but can be quickly adapted to become a fast, endurance style road bike.
The Tange Prestige steel frame naturally infuses generous amounts of comfort into the ride to help lower rider fatigue across even the roughest of road surfaces. The frame is partnered by a vibration-damping full carbon fork that offers two axle positions to alter its offset and length to give either more nimble or more composed handling in line with the terrain ahead.
Robust and low-maintenance Rondo 650b wheels team up with broad and plush 47mm all-road WTB tyres to lend a cushioned ride that’s full of traction across loose riding surfaces. 700c wheels with skinnier tyres can also be used in the frameset, giving the ride a fast, endurance road bike theme instead.
Removable mudguards are already installed, and rack mounting points on the frameset mean that vast quantities of luggage can be carried when on the longest expeditions. A Shimano 105 gear setup offers plenty of ratios for any topography, and the matching hydraulic disc brakes stop accurately and reliably in all weather.
