BMC has released a carbon version of its Roadmachine X, which was originally unveiled as an alloy bike back in 2018.
The new all-carbon frameset is aimed at the more adventurous end of the road market, with endurance-focused geometry and clearance for tyres up to 33mm wide – slotting it neatly into the growing 'gravel adjacent' category, BikeRadar's favourite phrase of the moment.
The carbon Roadmachine X’s frameset features BMC’s Tuned Compliance Concept (TCC) Endurance technology, which is a fancy way of saying BMC has altered the frameset's carbon layup to – the brand claims – introduce vertical compliance without compromising lateral stiffness.
BMC says TCC Endurance is the most compliant on-road version of its technology. The only more compliant category on BMC’s scale is TCC Gravel, and this is currently reserved for the BMC URS gravel bike.
The frame also has dropped flat-section seatstays and a D-shaped carbon seatpost, which should also introduce greater compliance into the bike.
With a 74.2-degree seat tube angle and 72-degree head tube angle across all sizes, BMC says the frame's geometry is endurance-focused. This is slightly more aggressive than the aluminium Roadmachine X's geometry.
BMC also says it’s kept the front centre of the bike long for stability but the chainstays short for fast acceleration.
The frame has clearance for 33mm tyres and, alongside two cage mounts, it also appears to have a top-tube mounting point.
BMC and SRAM components
The carbon Roadmachine X is available in two build options: the top-shelf Roadmachine X ONE and the second-tier Roadmachine X TWO.
Both builds use the same finishing kit from BMC, with an integrated stem design and D-section seatpost, as well as a Fizik Terra Argo X3 saddle.
BMC has specced both bikes with its own wheels; the Roadmachine X ONE gets 35mm-deep carbon rims and the Roadmachine X TWO gets 25mm-deep aluminium rims. Both bikes are fitted with 32mm WTB Expanse tyres.
Both bikes are also fitted with SRAM eTap XPLR 1x groupsets, with the Roadmachine X TWO getting a Rival-level groupset and the Roadmachine X ONE getting Force-level. Both bikes have a single 44t front ring and 10-44t cassettes.
