Light, stiff, and comfortable. Steering that’s stable, yet precise. These are the qualities that pros want and what you’ll find in the BMC Teammachine SLR03. Pros are paid to race all day long, and the lighter the bike, the easier it is to accelerate and lug over mountains, the stiffer the bike, the more power goes from the pedals into driving the rear wheel, the faster they can go. The more comfortable the bike, the less fatigue is felt, the more energy is left after a long day. Stable means you don’t have to think too much about where the bike is going, and precise lets you easily aim for, and pass through, the tiniest of openings.
All of this is possible because BMC used their Accelerated Composites Evolution (ACE) modeling to design the Teammachine line and apply it to pushing the limits of what is possible with the SLR01, but here, the limit they were pushing was keeping the price down while the performance high.
The geometry is classic BMC. You have short chainstays to keep the rear end stiff and the wheel underneath you. You have a relaxed head angle and short fork rake to nudge the trail out a bit while still allowing the bike to turn fast.
ACE is a modeling program that allows them to explore a huge range of possibilities in a compressed period of time. They input parameters and let it virtually shape, lay-up, and assemble thousands of frames and test them without creating a single frameset. They then apply this knowledge to finally physically build a frameset that can maximize materials, shapes, and geometries to produce the best possible product given the parameters.
Here, they wanted a bike that rode like the SLR01, but built with lower-modulus carbon. They also wanted the smallest frame to have a low stand-over height for smaller riders.
The rest of the SLR03 size run works within the same SLR01 parameters, but as the sizes are a little different, it’s only the 54 which matches up identically with the 54 SLR01. That 54 is also a 1230g frame, including paint and hardware.
The fork is 460g uncut. But other than the weight, the design is identical to the SLR01’s. It has the 1 1/8” to 1 ½” tapered steerer. It has the same stiff crown, and the same slender legs.
For simplicity’s sake, they kept the cable routing entirely external. It’s easier to work on as well. They stuck with a 27.2mm diameter round seatpost. The bottom bracket is BB86. The front derailleur mounts to a hanger. The max tire width is 25mm.
The bike comes built up with value-oriented groups that take advantage of Shimano’s commitment to trickle-down excellence–
When you’re looking for a carbon-fiber race bike that is gentle on the bank, the BMC Teammachine SLR03 offers one with WorldTour-worthy performance.
