We put BMC's disc brake all-rounder to the test
The BMC Roadmachine RM02 was designed to combine all the best elements of lightweight, aero, endurance and disc-brake road bikes in one all-round package, which is why it’s our Aero Bike of the Year for 2017.
BMC’s latest bike differs from many other disc brake machines in one crucial aspect. It was a bike originally conceived and designed from the ground up as a disc brake platform.
This has big implications as to how the frame is able to deal with the asymmetric forces disc brakes exert.
A relatively long fork steerer and a choice of two headset spacers lets the rider tailor the stack height between a race-style geometry or more relaxed set-up.
Aero features include very neat leverless thru-axles and tube shapes while there is also plenty of comfort built in to the stays and proprietary d-shaped seatpost.
There is also ample clearance for 30mm tyres. Factor in all these features and the Roadmachine scores high marks for versatility.
The spec is absolutely top drawer, with Shimano Ultegra 11-speed providing sublime shifting and DT Swiss R24 Spine wheels, which are robust and tubeless ready.
You also get Shimano hydraulic disc brakes with flat- mount calipers, a Fizik Aliante saddle and an 11-32t cassette.
I instantly felt comfortable on the BMC Roadmachine RM02 Shimano Ultegra. It rides like a greatest hits compilation of other BMC bikes, with features inspired from the rest of the range. It is beautifully poised and balanced and yet lively and fun.
The BMC Roadmachine RM02 is not just a great disc brake bike, it is a superb all-rounder that is a delight to ride.
The d-shape seatpost gives plenty of deflection and helps the rear end feel planted in the corners.
When braking hard, the bike is smooth, with no detectable shuddering or torque steer in the front end. The RM02 feels like it should always have had discs and not like a bike that has had them retro-fitted as an afterthought.
The BMC Roadmachine RM02 Shimano Ultegra is expensive but its versatility justifies this cost. Where previously you might have owned two bikes, you can now own one.
Disc brake bikes have previously been synonymous with endurance bikes, but the BMC Roadmachine RM02 breaks free of that, with a great all-round ride that should convince more riders than ever to make the switch to discs.
