You should choose the size of your bike based on your height, as well as your build (arm span and leg length).

If you are between sizes, the smaller size will give you a more athletic position, while the larger size will give you a more comfortable position.

M 173 182

L 182 190

XL 190 200

You can try out a Triban 120 disc in the store, since the frame geometry is identical.


Comfort-oriented frame geometry with a higher steering socket that offers a more upright position than a classic road frame. The GRVL geometry of the elongated top tube and shorter stem allow the fork to be moved forwards to avoid the foot rubbing against the front wheel.

6061 T6 aluminium sloping frame with semi-integrated headset.

Frame weight, size M: 1800 g


Carbon fork and aluminium pivot that are more lightweight and offer more precise directional control.

Aheadset 1"1/8 steerer tube makes the steering assembly strong and rigid.

Inserts in the fork to fit a pannier rack.

Maximum load on the fork: 9kg

Fork weight: 750 g


Promax DSK disc brakes.

DSK 330R "flatmount" front brake

DSK 300R "postmount" rear brake

160 mm front and rear discs

Anti-compression Jagwire KEB-SL housings to ensure precise and effective braking. They are reinforced with Kevlar and have a specially designed inner liner so the cables have an excellent slide

You will need to bed these brakes in. Simply brake gradually 20 times at a low speed (20 km/h), then repeat at 30 km/h. Make sure to bed in both brakes.

This creates better grip between the pad and disc.

Why choose a gravel bike rather than a road bike with fat tyres?

A gravel bike is not just a road bike with fat tyres. Even if it shares DNA with a road bike, gravel bikes have their own unique characteristics.

On our GRVL 120 gravel bike, we have changed the frame of our RC120 disc by adjusting clearance (tyre space) for riding with a 700x38 tyre. It also has mechanical disc brakes.

On this gravel bike, we also used our tubeless gravel wheels in 23c, and a single chainring drive train.



Bike frame: 100.0% Aluminium
