BMC has been dialing the Teammachine SLR01 towards perfection for years. With this latest iteration, their best has gotten better. Lighter, stiffer, more compliant, and, yes, disc brakes. As always, the SLR01 is balanced, but now even more so.
First, regarding discs. BMC, in their effort to build bikes for their race team, has pulled off an amazing feat, getting their disc brake bike nearly identical to their rim brake bike in terms of both weight and handling. If you dig into the geometry chart, you’ll see that the rim- and disc-brake bikes are identical. This is so their pro riders can switch from discs to rim brakes without giving a second thought to how the bike handles. The two framesets look similar, but not identical, as the disc brake forces necessitate asymmetric fork and chainstay designs. In terms of changes in geometry, the most significant is that the chainstays of the rim brake bike have been lengthened by 8mm, which is the minimum distance the discs need on the disc bike. A benefit to both bikes is that 28mm wide tires now will easily fit. They designed the frame around 25mm tires, in case you are wondering.
In terms of overall geometry, the BMC racing team, and the Swiss design engineers were quite satisfied with the handling of the previous SLRO1, so they didn’t want to do much to change it. They ever-so- slightly shortened the reach, but the rest of the angles have remained the same.
The handling also is a result of how the carbon is shaped and where the plied are laid. Here, too, they were quite happy with the previous iteration, so they only wanted to increase compliance and bottom bracket stiffness. They did both. Part of this is removing material and reshaping where they want the compliance, and adding material and reshaping where they want the stiffness. And to finish the job, they tweaked the seatpost and moved the seatpost clamp downwards into the frame, both of which improve comfort.
Both bike have DTI, Dual Transmission Integration, to keep the bike as clean and aero as possible. There’s a plate at the top of the downtube, just behind the head tube, which is where cables go in, or electronic wires, including a Shimano Di2 charging port, or it can be covered over completely for SRAM’s eTap shifting. If you go for the rim-brake version, the rear brake cable runs inside the top tube and has a ball-and-joint cable stop in the top tube where the rear brake cable runs into the frame. Less friction, better action. If you go with mechanical shifting, there are flexible fiberglass tubes running inside the frame to guide the cables and keep them oriented properly and quiet. If you go for the disc-brake version, the included stem, sized to the frame, is where you run the hydraulic hoses, and it mates with a unique steerer tube that provides room for the hoses to run into the frame and fork. They call it their ICS, or Integrated Cockpit System. The stem is also aero, comes with interlocking spacers so you don’t have to remove the stem to adjust its height, and the stem mates with all 31.8mm center-section bars and even has an integrated computer/GoPro mount.
The seatpost on both frames is included. It is their Teammachine SLR01 Premium Carbon “D” (for shape) compliance post. Weight is 195g. Standard offset is 15mm, and a zero offset post is available. The frame also comes with a replaceable front derailleur mount and replaceable ultra light rear derailleur mount. The fork has a tapered 1 1/8” to 1 ½” steerer. The bottom bracket is BB86.
The disc brake version comes with flat-mount disc-brake mounts. There’s a 12 x 100mm front axle and 12 x 142mm rear axle. The axles are tapered and weigh 55g for the set. The fork is designed for a 160mm rotor. The stays are designed to work with either 140 or 160mm rotors.
The rim brake version saves weight and increases performance by utilizing direct-mount brakes. Shimano, TRP, and Campagnolo all have versions that work with this standard.
Weight for the SLR01 is feathery. They measure the 54cm size. The rim-brake version weighs 810g for the frame, 350g for the work. The disc-brake version weighs 815g for the frame, 355g for the fork.
The Teammachine SLR01, both disc and rim versions, refine BMC’s concept of the perfect road bike.
