BMC is continually examining their offerings to make sure they’re as cutting edge as practical. They want to move their bikes forward, but are content to keep them as is until they’re ready to execute the improvements. The Roadmachine 01 changed what endurance bikes are about. They’re satisfied with the design for now, and have updated it for 2018 with fresh new colors and updated componentry, keeping those aspects of the frame as cutting edge as is practical, too. Owing to the popularity of out-front computer mounts and cameras, the ICS 01 stem comes with mounts you can add on to the faceplate, further reducing clutter and, and keeping the aerodynamics as slick as possible.
The stem is not only a looker, but shows how thoroughly BMC rethought the front end. The brake hoses run through the stem and into the frame without seeing daylight. The front brake hose comes out of the fork leg just above the flat mount. The rear hose goes into the downtube and out on the left chainstay. Hydraulic brakes only. If you’re running Shimano Di2, the wire runs internally. If you’re running mechanical shifting, the cabling goes around the top tube
And the stem sits atop what BMC is referring to as a cone. The standard has 2cm of stack and gives you a stack equivalent to the GF bikes. There’s a second low-stack cone, purchase separately, that has zero cm of rise. An extra 10mm spacer comes with the bike and stem, but any 1 1/8” round spacer will work. Stem lengths are 90mm for the 47 & 51, 100mm for the 54, 110mm for the 56, 120mm for the 58 and 61. The stem clamps to a standard round 31.8mm diameter handlebar. And BMC is working on integrated mounts for computers and cameras.
As with any endurance bike, comfort and stiffness need to be baked in. Both layup and shaping play important roles. That’s why there’s the beefy 1 ½” lower end of the tapered steerer and beefy fork crown atop slim fork legs. Likewise, at the back, the angle compliance seat stays attach low on the seat tube. The shaping here results in vertical compliance that is greater than the Teammachine but less than the Gran Fondo. The D-shaped seatpost, designed specifically for the Roadmachine, is carbon, and engineered for compliance as well. 15mm setback, btw.
In terms of both bottom bracket stiffness and head tube stiffness, the Roadmachine sits between both bikes as well, stiffer than the GF and not as stiff as the Teammachine. You can see the work with the elongated head tube, the notch for the fork, and the massive bottom bracket juncture as well as chainstays that start off beefy and slim down, similar to the design of the fork blades. The BB standard is PF86, and atop it sits an integrated chain guide, designed to eliminate dropped chains.
The geometry furthers the cause of a super-fast endurance bike. The chainstays are shorter than you’ll find on the GF. With the wheel better tucked underneath you, accelerations are easier. There’s 63mm of trail, a bit longer than a racing bike, but helps with stability. The bottom bracket drop is a generous 71mm, meaning you’ve got a low center of gravity, which makes both slow grinding climbs, and speedy descents easier.
And with disc brakes, they’ve opened up tire selection. Up to 30mm in diameter will fit. As mentioned earlier, the frame is designed for hydraulic brakes only. You can run 160 or 140mm in front thanks to BMC’s proprietary mount. With the rear, you can mount a 140mm via direct mount and 160mm with flatmount adapter. The hubs roll on 12mm thru-axles, both front (100mm) and rear (142mm). The thru-axle design improves stiffness, drops weight, and makes wheel changes easier.
The Roadmachine 01 is high-speed fun for those who want a fleet of one.
