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, a third bottle mount, rack and guard mounts and fixings for Anything Cages on the forks complete the package.
