BMC Crossmachine CX01
All the usual bells and whistles are present for a top end race frame: Electronic gearing compatibility, internal cable routing, super wide downtube, BB86, press fit bottom bracket, huge chainstays, slender seatstays and tapered fork and steerer. For a race-focused company, the disc brake specific nature of the frame will offend some traditionalists (the keen eyed among you will notice the prototypes tested in the first photo had canti brakes) but according to product managers at BMC, they were keen to embrace the latest technology. We’re certainly not going to argue with that.
With a myriad of experience in carbon fibre manufacture thanks to their success in the road bike market, its no surprise to see BMC bring their knowledge to the for with an all new, full carbon Crossmachine CX01.
In order to perfect (in their eyes) the weight and stiffness requirements for their range topping, super light road bikes, BMC developed a computer system that runs 1000’s of iterations of carbon fibre lay ups and tests them virtually. Known as the ACE Technology Software, this pre production ‘testing’ means the designers should have a pretty good idea what the tube shape and ply book will result in when everything is bolted together to test. The CX01 used the very same system and the end result is this 1100gram (claimed), 54cm frameset.
Both a complete bike, and frameset will be available in 5 sizes ranging from 48 to 60. A wide spread given the number of options and the jumps at the lower end are bigger than with some other brands. Maybe we will see an updated size range at a later date? Frame, fork, BMC’s own TCC seatpost and ancillaries squash a scale by just 1540 grams. Given a seatpost usually weighs 170plus grams, and seat collars and cable guides a further 30-50 minimum. It’s an impressive weight for an all carbon disc fork but we’ll wait to see what the production items weigh and how they perform once we get one into the grit.cx test fleet. Complete bikes are only available in one spec level – Sram Force CX-1 – again a nod to BMC’s design team following trends. The single ring, 11 speed group is finding favour among many forward thinkers, and early impressions seem favourable as to the reliability of the MTB proven clutch protected rear mech and a narrow wide chainring tooth pattern. AS of this moment, we’ve no UK pricing, but you can expect to pay a fair chunk of change for this top race level frame.
