Kevin of Steel - Curve GXR Steel - Grovel V3


Have you ever heard of a titanium superhero? No, Superman is the man of S_T_E_E_L. While our Ti Kevin is staring in the pond, Kev of Steel is defending the planet from baddies. While Ti Kevin is busy grooming, our steel hero is defeating dictators and saving kittens from burning buildings.

Titanium may make a nice piece of jewellery, but swords are made of steel, and are the most honourable of weapons, reserved for nobility. Whether you’re protecting an empire, performing a decapitation or conducting a ritual sacrifice, steel is your material of choice.


Frameset Package £1,295

Don't be fooled by the name, or do. Kevin also goes by the name GXR, The Grovel V3, or even the Grovel Xross Randonneur, but we call it Kevin.

Again these steel steeds are a limited release.

Open your mind to some new numbers with the GXR. It's long, so run a short stem to get the best handling out of this puppy.

For example if you are fitted to a 54cm road bike running a 110mm stem, we advise a Medium GXR with an 80mm Stem or similar.

Be aware - Stand over is tall. Even on the smaller sizes. Why? Because cargo space on long adventures is important! We wanted to enable shorter riders to hold as much cargo as possible, so the larger triangle won the battle of cargo vs. standover.
