THE FOLLOWING CALCULATION WILL HELP YOU FIND THE RIGHT BIKE FRAME SIZE AND SADDLE HEIGHT:

Road/Gravel Inside leg x 0,66 = Frame size in cm
MTB Size S: 155 – 172 cm body height
Size M: 173 – 182 cm body height
Size L: 183 – 192 cm body height
Size XL: >192 cm body height
Fitness
or
Inside leg x 0,61 = Frame size in cm
Inside leg x 0,24 = Frame size in inches
Hybrid/Touring
or
Inside leg x 0,61 = Frame size in cm
Inside leg x 0,24 = Frame size in inches
Inside leg x 0,885 = Saddle height on all bikes

If you are exactly between two sizes, you'll have the choice: Choose the smaller frame if you prefer a "racing position" and the bigger frame if you prefer a more comfortable "touring position".

See our video step-by-step instructions on how to determine your frame size. We'll explain you how to easily measure shoulder width, inside leg length and arm length yourself.

Shifting performance at its best

With the SRAM shifting system around the X01 Eagle rear derailleur, you are best equipped for any tour. The 520% gear range of the cassette lets you climb any mountain and, moreover, the ROLLER BEARING CLUTCH prevents a wobbling rear derailleur and chain slap even on the roughest trails. The X-SYNC technology ensures a precise shifting performance even under high load, thanks to improved chain retention and excellent self-cleaning properties.

The SRAM G2 RSC disc brake decelerates precisely in every situation – its four pistons offer you massive braking power with first-class modulation. Thanks to the individual adjustment possibilities of the brake levers and their ergonomics, the G2 shines with outstanding user-friendliness.
