Despite my best efforts, I couldn't coax any chain rub out of the front derailleur. To get the best out of it, I found I had to be a bit more active with my weight shifts and really commit to line choices.Īll those oversized tubes and the tapered headtube have combined to create a really solid platform for laying down the power. Through switchbacks, the Xenith feels quite neutral, neither diving into the corner nor feeling like an oil tanker. I found this to be a good compromise between a razor sharp crit racer and a more laid back all-day cruiser.
Geometry wise, the Xenith features fairly standard parallel 73 degree head and seat tubes, giving a trail figure of 58mm. For a more in depth look at the frame and componentry, go check out what we had to say when the Jamis Xenith Pro hd just landed at HQ. The bottom bracket is a suitably large Pressfit 30 number though an adaptor is used for the Shimano Ultegra cranks so you don't get the full stiffness benefit there. Up front, a tapered fork keeps everything pointing in the same direction while the downtube and stays combine to form a solid power transferring platform. The frame comes out of the same mould as the top level Xenith SL, employed by the UCI continental Jamis/Sutter Home squad in the US, only with lower grade fibers so you'd expect it to be racy. At £2400, the Jamis is among the cheapest carbon-framed Ui2 bikes out there, but it's more than just a groupset, it's also a pretty decent bike in its own right.
The Jamis Xenith Pro Di2 is one of the new crop of bikes using Shimano's Ultegra Di2 group to bring electronic shifting to the masses (or at least, down to a more affordable price point).
