Weight: 21.6 lb. (XL)
BMC has constructed its repute on innovation, type, and premium bikes. Hardly ever has the Swiss model scored excessive marks within the worth division, as an alternative buying and selling closely on the cachet of its title to command excessive costs. However the brand new Twostroke 01 One flips that script on its head.
This bike is a high-performance hardtail aimed squarely at value-minded riders. BMC cleverly orchestrated its mixture of high-end and price range components to retain the texture of a premium bike with out commanding a commensurate value. Exhibit A: The body is made with BMC’s premium carbon. It’s nothing new for the model to make use of its greatest carbon on bikes that sit a number of rungs down on the product lineup. The Fourstroke 01 Three has precisely that, besides in that case the high-end body is balanced out by low cost components and heavy wheels that overshadow the body.
Efficiency and worth apart, it wouldn’t be a BMC if there wasn’t additionally a heavy concentrate on aesthetics. Objectively talking, trying quick doesn’t assist you go fast, however it positive doesn’t harm. The engineers took their design inspiration from the F-35 fighter jet, and that affect is most evident the place the seat stays meet the highest and seat tubes in a style that resembles the backswept wings of an airplane.
5 Issues We Love About The BMC Twostroke 01 One
The modern strains and blocky, geometric shapes proceed with the flattened high tube and enormous, oversize downtube. The rear brake hose and shift cable tuck neatly contained in the body, and hidden contained in the headtube is a fork stopper that protects the body from injury by the fork within the occasion of a crash. As with the Teammachine SLR01 One, the D-shaped carbon seatpost on the Twostroke 01 One is meant so as to add vertical compliance. On condition that form, it might shock you to study that the Twostroke can, in reality, work with dropper posts—a shim inserted within the seat tube makes the bike appropriate with 27.2mm internally routed dropper posts. That dimension limits your choices, however we’d take greater problem if the bike wasn’t appropriate with any droppers.

The bike rolls on aluminum tubeless-ready DT Swiss hoops with 25mm-wide rims, and is hung with a mixture of SRAM GX and X01 Eagle components. The rear shifter is from the newly redesigned GX Eagle household, and the improved, smoother really feel of the lever is clear. It’s additionally useful that it’s transferring an X01 Eagle rear derailleur, yet one more instance of cautious part choice to steadiness value and efficiency by BMC.
The 100mm RockShox SID Choose is a mid-range fork that, though not as refined as its costlier siblings, performs fantastically on each tough and rocky East Coast paths and easy and quick circulate trails.
Our Twostroke 01 One sits atop the Twostroke 01 household, and all bikes share the identical premium carbon body. Subsequent in line is the Twostroke 01 Two. For $3,299, you get an entire SRAM GX Eagle drivetrain and a RockShox Reba RL fork. The Twotroke 01 Three has a mixture of SRAM NX and GX Eagle components, a RockShox Recon Silver RL fork, and can set you again $2,699.

Trendy XC Geometry
As you’d count on from a motorbike touting fashionable XC geometry, the Twostroke 01 One is longer, decrease, and slacker than the Workforce Elite hardtail it replaces. A 67-degree head angle is extra relaxed by half a level than the laidback Specialized Epic, and also you’d be forgiven for considering such a slack entrance finish would negatively have an effect on low-speed dealing with. It doesn’t. Conversely, the 75-degree seat angle could be very aggressive however goes a great distance towards preserving weight over the again wheel on steep climbs.
By way of match, the Twostroke is on the longer aspect. Our XL take a look at bike had 485mm of attain, 5mm greater than the already lengthy Specialized Epic Hardtail, and 25mm longer than the Cannondale F-Si. The 623mm stack peak is 13mm decrease than the previous and 12mm decrease than the latter.
A Hardtail For Purists And Newbies Alike
As manufacturers replace the geometry on XC bikes to be extra in keeping with present developments in course design, I’ve begun to note a shift in efficiency. In some circumstances, low-speed maneuverability appears to be a casualty of constructing a motorbike that may haul on tough, gnarly downhills. These bikes really feel greatest at race pace however at instances slightly unwieldy when tackling the rocky backcountry-style trails which can be widespread close to our HQ in southeastern Pennsylvania. What struck me straight away is how straightforward the Twostroke 01 One was to wrestle by means of these trails. Sluggish, tight, and technical introduced no hassle in any respect, and the bike provided a stage of compliance that’s unusual on hardtails. It had a sense just like the Trek Procaliber 9.7, with its IsoSpeed decoupler, however with out the slight bobbing sensation.
That’s completely in keeping with the objectives BMC laid out when designing the Twostroke—consolation and compliance had been as excessive on the record as efficiency. With that stage of consolation (have in mind this can be a hardtail, so consolation is a relative time period), there’s an edge that’s misplaced. The bike is as stiff and conscious of pedaling enter as you may ask for from any carbon hardtail, however it’s way more subdued than the spunky Specialised Epic Hardtail Professional.
The Twostroke 01 One strikes a beautiful steadiness between efficiency for riders who like the texture of a hardtail—purists who respect that type of unfiltered driving—and people simply dipping their toes into the XC waters.
