Visually, the BMC Teammachine SLR01 ONE leaves no doubt that it wants to go fast everywhere. The fully integrated design indicates good aerodynamics and the shallow rims suggest that the bike climbs fast. Will this impression be confirmed in comparison with the four fastest race bikes of the 2021 season?

The BMC Teammachine SLR01 ONE sits between the Timemachine Road on the aero side and the Roadmachine on the endurance side in the BMC portfolio. And between these two, it spreads itself extremely wide: with excellent vibration damping, it displays near to all-road qualities, while its aerodynamics rival the Timemachine Road in terms of efficiency on the flats. This makes it BMC’s most versatile road bike. Our test bike comes with a wireless SRAM RED eTap AXS groupset with 48/35 t chainrings and a 10–28 t cassette. This gives the gearing closely spaced ratios, especially in the high gears, always letting you find a comfortable cadence. However, for demanding climbs, a slightly easier gear or stronger legs don’t hurt. The shifting performance is as quick as usual and the hydraulic disc brakes with 160 mm rotors at the front and rear are beyond reproach. The bike doesn’t currently come with a power meter, though BMC have recognised that this is a no-go at this price and will remedy this for the next generation.

First-class aerodynamics for high speed and the best vibration damping for rough roads – the Teammachine SLR01 ONE is the most versatile bike in the BMC portfolio.

For one mould
With the Teammachine SLR01 ONE, BMC take integration to the extreme, or rather, right down to the Aerocore bottle cages. These nestle seamlessly into the down tube and seat tube, helping to keep airflow clean and the aerodynamics optimal.
Is this still a cockpit or already art?
Although all the test bikes have a pretty sleek cockpit, the Teammachine still stands out. The handlebar-stem unit could not be more svelte and makes a statement with its shape and bright red colour.
On shallow rims
With the DT Swiss PRC 1100 DICUT Mon Chasseral wheels, the BMC rolls into the test on the shallowest wheels. Paradoxically, with these fitted, we would have expected the BMC to be stronger on the mountains than on the flats, but the opposite is the case.

Under the radar
BMC calls it Stealth Dropout Design, but what does it mean? The thread for the thru-axle doesn’t go all the way through the dropouts. This creates an extremely clean surface #marginalaerogains!
A fine tire
The Vittoria Corsa Graphene 2.0 tires on the BMC not only contribute to good vibration damping but also generate massive braking and cornering grip. When leaned over, their tread produces a whirring sound that takes some getting used to.
Full steam ahead?
Yes, of course! But how much power is that? For a bike at this price, we would have expected a power meter as standard. Fortunately, BMC are remedying this for the next generation.

700 x 25C Vittoria Corsa Graphene 2.0 tires are mounted on DT Swiss PRC 1100 DICUT Mon Chasseral wheels, which are the shallowest in the test field with a depth of 24 mm. The tires measure 27 mm wide and provide first-class vibration damping. A particular highlight of the BMC Teammachine SLR01 ONE is its one-piece ICS carbon cockpit. Together with the Wilier Filante SLR cockpit, it constitutes the cleanest and tidiest solution in this test. The stem is 110 mm long and the handlebar 420 mm wide. In size 56, our test bike weighs 6.86 kg and will change hands for € 10,999.

In terms of speed, the BMC Teammachine SLR01 ONE is a paradox. With the 24 mm deep DT Swiss PRC 1100 DICUT Mon Chasseral wheels, we would have expected particularly good performance on the uphills and in return would have countenanced losses on high-speed sections. However, the opposite is the case: despite the shallow rims, the bike is the second-fastest bike after the Tarmac on flat and undulating terrain. This indicates excellent aerodynamics for the frameset, including the ICS carbon cockpit, and is underlined by aero details like the stealth dropout design. Added to this are the fast-rolling Vittoria Corsa Graphene 2.0 tires. With deeper aero wheels, the BMC would become a real aero weapon. On the other hand, its climbing abilities, while far from bad, rank at the bottom of this very strong test field. An easier gear would help with riding efficiency at low speeds.

On the downhills, the bike is back on track and convinces with great braking and cornering grip. Solely the loud whirring of the tires when leaning the bike over can be a little unsettling initially. That said, over time the sound becomes an audible marker of how close you are to the limit. The extrapolated 150 km test route with almost 2,000 m of climbing was covered at an average speed of 26.1 km/h and took 5 h 44 m 48 s to complete.

When it comes to handling and comfort, the Teammachine surprises with a remarkable balancing act: no other bike in the test is so smooth, only to turn into a corner so mercilessly. Experienced riders will love this schism but for the inexperienced, it could lead to tricky moments. There is also a balancing act when it comes to comfort: in terms of vibration damping, the BMC is at the top of the field, together with the SCOTT, and even smaller impacts are noticeably damped. The cockpit, seat post and especially the tires do a great job here. On the other hand, there is a racing stiffness to the bike that converts every watt into propulsion. In turn, larger impacts are transmitted to the contact points just as directly as its competitors. Apart from the well-known rattling of the SRAM shifters, the Teammachine is also extremely quiet. In addition to the excellent braking performance, two other factors contribute to the high sense of security for experienced riders on the bike: the lowest sensitivity to crosswinds in the test and its balanced, tenacious grip on the road.

Tuning tips: a 33 t cassette could make long and steep climbs a little more pleasant | deeper aero wheels would catapult the bike from very strong to outstanding when it comes to efficiency on the flat | fit a power meter

A strong second place for the BMC Teammachine SLR01 ONE! On the test track, it stays closest on the heels of the S-Works Tarmac SL7 and convinces with its combination of race performance and the best comfort in the test field. Experienced racers will celebrate the combination of stoic stability and maximum directness, while newcomers may quickly be overwhelmed by its directness. Nevertheless, the BMC is one of the most versatile bikes in this test!


  • low susceptibility to crosswinds
  • rides very fast on the flats despite the shallow wheels
  • great balance between racing stiffness and comfort
  • combination of smoothness and directness


  • falls short of our expectations on the hills
  • rattling SRAM shift levers
  • no power meter installed
