Why buy bike from us?

One bike to rule them all.

Our original do it all go anywhere bike is back and more capable than ever before!

Commuting duties during the week then epic, multi-terrain adventures at the weekend, the Croix de Fer 20 is a capable and adaptable beast that rarely gets fazed whichever way you point it.

The heart of the bike remains a complete Reynolds 725 frameset, defined by its reliability wherever you ride.

We have however made a few updates to add to the Croix de Fer's versatility.

The ability to run up to a 45mm rear tyre and a 50mm front tyre on the provided 700c rims increase the all-terrain ability of the Croix. If you want to experiment with 650B wheels, you could run up to a 44mm rear tyre and a 50mm front tyre.

Standard QR dropouts mean your 9mm wheelsets can keep turning for another few years - and the practicalities don't end there.

The drivetrain has been upgraded to Shimano's excellent GRX, featuring a 46/30T double chainset, an 11-34T cassette and RX400 derailleurs for reliable, smooth shifting.

Tubeless ready rims and tyres, flat mount disc brakes, a third bottle mount, rack and guard mounts and fixings for Anything Cages on the forks complete the package.
