Evaluation: BMC Teammachine R Street Race Bike
The BMC Teammachine R launched in October with the formidable purpose of being the right highway racing bike. Whereas I didn’t get to check it in a race, I did journey to the Circuit of the Americas race observe in Austin, TX, to affix BMC for check laps, plus a day of around-town using by myself. Beneath are my impressions of the bike, however first, a bit about the way it got here to be.
Why did BMC associate with Crimson Bull?
BMC’s racers needed a motorbike that would deal with the cobbles in addition to the climbs, flats, and sprints, giving them a one-bike quiver for many races and levels. Having already collaborated with Crimson Bull Superior Applied sciences (RBAT) to create their Speedmachine TT/Tri bike, they determined to leverage the beverage model’s F1 expertise and tech for this, too.
So BMC went to Crimson Bull and mentioned that they had three standards:
- It needed to be as aero as their Timemachine
- It ought to have the identical really feel as their Teammachine SLR
- It needed to be actually mild
RBAT gave them extra pc simulation energy, letting them check extra tube shapes and layup schedules. As soon as Crimson Bull’s computer systems had their model of a super bike, BMC got here in and tweaked it into one thing that would really be manufactured at scale.
The preliminary renderings confirmed a extra bulbous head tube, however it could have been heavier than the slimmer profile with flatter sides, as a result of (BMC says) rounded, bulbous shapes want extra carbon than flat shapes, a minimum of in that exact utility. They usually wanted it to “look” like a BMC, in spite of everything.
The top result’s a motorbike that’s 19% quicker than the SLR with no rider, 3.5% quicker with rider, and 1.9% quicker than Timemachine Street, all at 0° yaw within the wind tunnel.
Whereas BMC isn’t calling it an “aero bike”, it’s certainly a race bike that occurs to be very aerodynamic.
Full tech particulars are in our launch protection, however the important thing aero options are:
- Slim headtube and frontal profile
- Extraordinarily large spacing between fork leg and spokes
- Deep, lengthy backside bracket part
- Built-in bottle cage that shapes airflow over water bottles
They are saying with the fork, you both need to be extraordinarily near the wheel and tire, or actually removed from it. It’s safer and simpler to go large, and that enables extra rim and tire compatibility.
They spec a 1700g wheelset with 62mm deep rims, so you might go lighter, however they selected these particularly for the aerodynamics.
The bike can also be actually mild, solely ~50g heavier than the SLR. Claimed body weight is 910g with a 345g fork. They did this by decreasing overlap between plies with extra custom-cut items of carbon, utilizing much less the place it’s not wanted and somewhat extra within the head tube and BB space for improved stiffness.
BMC Teammachine R experience assessment
The Circuit of the Americas observe is a superb testing floor for this bike. Every 3.4 mile lap has 20 turns, one huge punchy climb, and what appeared like a relentless headwind. Powering down the straightaways, standing to hammer up the climb, or diving into corners and S-curves had been all nice. It’s stiff, environment friendly, and handles nice, as I’d count on from a race bike costing $14,999 in high trim. (Full bikes begin at $9,199, frameset with cockpit is $5,999)
Whether or not drafting others (or flatbed tractor-trailers with vacationers on the again) or pushing previous them for a solo effort, the bike clearly likes to cheat the wind.
As BMC’s personal numbers recommend, although, the rider continues to be the most important supply of drag. In order that they gave the bike very slender handlebars. All measurement body sizes, from 47 to 61, include the identical one-piece bar stem measuring 360mm large on the hoods. It flares to 420mm within the drops.
The purpose is to maintain a rider’s arms narrower, making a smaller frontal profile. As an even bigger rider with broader shoulders who sometimes rides 440mm large handlebars, I used to be stunned that this didn’t trouble me. Not less than not given the bike’s intent. Had been I shopping for this for all-day using and coaching, I’d need one thing wider. However for racing, this spec makes plenty of sense and wasn’t uncomfortable.
What stunned me in regards to the Teammachine R is how effectively it rode as soon as I bought off the superbly easy asphalt of a Components One race observe. I took it for a late morning experience out of downtown Austin, the place the roads are lower than good. Potholes, building zones, and metropolis streets. After which a much less congested experience alongside their bike paths straddling the Colorado River.
With unfastened scrabble to hard-packed filth, the path is the sort of factor I’d usually take an all-road or gravel bike on. However the Teammachine R, for all of its stiff hi-mod carbon, didn’t beat me up. If their group needed one thing that would deal with cobbles, this was the closest I bought to recommend BMC delivered. The one limitation for mere mortals like me is its claimed 30mm tire clearance. Nevertheless that appears to be the popular measurement for the professionals racing Paris-Roubaix, so… it’s positive.
Should you’re searching for a purpose-built all-around race bike that doesn’t skimp on any of the three key standards (aerodynamics, weight, experience high quality), the BMC Teammachine R is value a glance. It’s even positive with the post-ride taco truck cease, which earns it an additional nod from me.
