We wanted to take the hassle out of buying your next bike, so we worked closely with our partner brands to create the essential gravel bike for all riders and abilities. 
The specification is based on our own rider testing around the trails of Northern Ireland, and reflects a truly reliable and high performance bike build.

Don't like it, no fuss, just switch it up for the parts you want or upgrade to a higher specification component for increased performance.

'Fit for you' 

Everybody is different, and we know that cockpit configuration can make or break your riding experience.

Dont like wide handlebars, or fancy a different wheel size? Maybe you want to add a dropper seat post for that extra confidence when the trail takes a turn and points you downhill. You can switch out any of these in our bike builder and customise your ride just the way you want it.

Shimano GRX RX810 2x11 Groupset.

The Shimano GRX RX810 2x11 groupset is the result of two years of close collaboration with Gravel enthusiasts from around the world. It consists of a 2x crank (31-48 t), front derailleur, rear derailleur, disc brake with Di2 shift lever left and right, chain and cassette. Shimano didn't want to tell the Gravel specialists what to ride, but asked them what they wanted instead. Many unpaved paths were explored, off-road races contested, bikepacking tours undertaken, a lot of dust swallowed and mud bath galore. The result is the world's first Gravel-specific component groupset, the GRX by Shimano.

  • GRX ST-RX810 shift/brake lever (left + right)
