We’ve used lightweight 6061 aluminium to build the Dial into a truly lightweight bike without compromising on strength or performance. A flattened top tube provides lateral stiffness for maximum pedalling efficiency and cornering precision, whilst providing a degree of vertical compliance for a more forgiving ride over distance.

Quick out the blocks with its low frame weight, lightweight XC-specific wheelset and fast tyres, the Dial provides instant acceleration and with 100mm of travel up front, carries its speed well over rough terrain. The 430mm chainstays are compact for agile cornering, without being so short that you lose power on the climbs. It's a ride that makes is perfect for long days out where you want more comfort and control than a gravel bike or to die flat out on your local leg-tester.

Geometry and Sizing


It is important to get the right size bike, if the bike fits it will be faster, more comfortable, and easier to handle. You can also take into consideration the standover height to ensure you pick a bike that will be a good fit. If you measure your inside leg and ensure there is a minimum of an inch from the toptube to your crotch this will give you enough seatpost adjustment to find your optimum saddle height. Generally we recommend:
Riders between 5ft 2in and 5ft 7in
Riders between 5ft 6in and 5ft 10in
Riders between 5ft 9in and 6ft 2in
Riders of 6ft 2in +
