If you’re in the market for a high-performance cross-country mountain bike that blends cutting-edge technology with Swiss engineering precision, the BMC Fourstroke 01 THREE stands out as a top contender. Designed for riders who demand speed, efficiency, and control on demanding trails, this bike has earned its reputation in the competitive world of XC racing and recreational riding alike. In this in-depth blog post, we’ll explore everything you need to know about the Fourstroke 01 THREE, from its innovative features to real-world performance, helping you decide if it’s the right addition to your cycling arsenal.
At the heart of the Fourstroke 01 THREE is its premium carbon frame, crafted with meticulous attention to detail. BMC, a brand synonymous with innovation, has engineered this frame using advanced carbon layup techniques to achieve an optimal balance of lightness and strength. Weighing in at around 2,200 grams for the frame alone (depending on size), it’s one of the lighter options in its class, making it ideal for climbing steep inclines without sacrificing durability on descents.
The geometry of the Fourstroke 01 THREE has been updated to suit modern XC courses, featuring a slack head angle of about 67 degrees and a reach that promotes stability at high speeds. This progressive design ensures the bike handles technical terrain with confidence, whether you’re navigating rocky sections or powering through flowy singletracks. Internal cable routing keeps the aesthetics clean and reduces drag, while the Boost 148mm rear spacing enhances wheel stiffness for better power transfer.
One standout feature is the integrated RAD (Rapid Adjustment Dropper) seatpost, which allows for seamless saddle height changes on the fly. This is particularly useful in races where quick transitions between climbing and descending are crucial. Available in sizes from small to extra-large, the Fourstroke 01 THREE caters to a wide range of rider heights, ensuring a custom fit for optimal comfort and control.
What sets the Fourstroke 01 THREE apart in the suspension department is BMC’s proprietary APS (Advanced Pivot System) dual-link design. This system provides 100mm of travel both front and rear, delivering efficient pedaling without bob or energy loss. The kinematics are tuned for a progressive feel, meaning the suspension ramps up towards the end of the stroke to prevent bottom-outs on big hits.
Paired with high-quality components like the RockShox SID SL Select fork and a matching rear shock (often a RockShox Deluxe or similar), the Fourstroke 01 THREE absorbs bumps smoothly while maintaining traction. Riders praise its sensitivity to small trail chatter, which enhances grip during climbs and corners. The three-position remote lockout allows you to firm up the suspension for sprinting on smooth sections, making it versatile for both racing and all-day adventures.
In reviews, the suspension is often highlighted for its quiet operation and minimal chain slap, thanks to thoughtful design elements like the carbon upper link that reduces weight and flex. This setup not only improves efficiency but also contributes to the bike’s overall playful and agile ride quality.
The Fourstroke 01 THREE comes equipped with a reliable Shimano SLX 1×12 drivetrain, offering a wide gear range for tackling varied terrain. The 10-51t cassette paired with a 32t chainring ensures you have the low gears for grueling ascents and high gears for flat-out speed. Shifting is crisp and precise, even under load, which is essential for maintaining momentum in competitive scenarios.
Braking duties are handled by Shimano SLX hydraulic disc brakes with 180mm front and 160mm rear rotors, providing powerful modulation and fade-free performance. The wheels are typically DT Swiss X 1900 or similar, wrapped in Vittoria Barzo tires with a 2.35-inch width for excellent rolling efficiency and grip. These tubeless-ready setups reduce the risk of flats and allow for lower pressures to enhance traction.
Other notable components include a lightweight alloy handlebar, ergonomic grips, and a Fizik saddle, all chosen to keep the total weight under 11kg (24lbs) for most builds. For those looking to upgrade, the frame is compatible with higher-end groupsets like Shimano XT or SRAM GX, offering room for personalization.
When it comes to on-trail performance, the Fourstroke 01 THREE excels in cross-country environments where speed and agility are paramount. Its efficient pedaling platform shines on climbs, allowing you to spin up hills with minimal energy wastage. The geometry inspires confidence on descents, with the slack head angle and short chainstays (around 435mm) promoting quick maneuvers and stability.
Testers note that the bike’s rear wheel traction is exceptional, thanks to the APS system’s ability to keep the tire planted. This makes it a favorite for technical XC races, where maintaining speed through roots and rocks is key. On smoother trails, the Fourstroke 01 THREE feels lively and responsive, encouraging you to push your limits.
However, it’s worth mentioning that with only 100mm of travel, it’s not designed for aggressive enduro-style riding. If you’re eyeing more demanding downhills, consider the Fourstroke LT variant, which bumps travel to 120mm for added capability. Overall, the Fourstroke 01 THREE strikes a perfect balance for riders who prioritize efficiency without compromising on fun.
Like any bike, the Fourstroke 01 THREE has its strengths and areas for consideration. Here’s a balanced look:
In the crowded XC market, how does the Fourstroke 01 THREE stack up? Compared to the Specialized Epic EVO, it offers similar travel but with BMC’s unique APS system providing a slight edge in pedaling efficiency. The Trek Supercaliber, another rival, features an IsoStrut shock for a more integrated feel, but the Fourstroke 01 THREE’s dropper post gives it an advantage in technical sections.
Against the Scott Spark RC, the BMC model holds its own with comparable weight and geometry, though the Spark might appeal more to those preferring TwinLoc suspension control. Priced competitively, the Fourstroke 01 THREE often comes out on top in reviews for its balanced ride and innovative tech.
If you’re upgrading from an entry-level bike, the jump to the Fourstroke 01 THREE will feel transformative, offering pro-level performance without the ultra-premium price tag of models like the Fourstroke 01 ONE.
To keep your Fourstroke 01 THREE performing at its best, regular maintenance is key. Check the suspension pivots and linkages every few rides for wear, and service the fork and shock annually. The internal routing makes cable replacements straightforward, but use quality tools to avoid damage.
Tire pressure should be adjusted based on rider weight—around 20-25 PSI for most—and always run tubeless to minimize punctures. Clean the drivetrain after muddy rides to prevent premature wear, and inspect the dropper post mechanism for smooth operation.
In conclusion, the BMC Fourstroke 01 THREE is more than just a bike; it’s a gateway to elevated riding experiences. Whether you’re chasing podiums in XC races or exploring local trails, its blend of lightweight design, advanced suspension, and reliable components makes it a standout choice. With positive feedback from riders and experts alike, investing in the Fourstroke 01 THREE could be the upgrade that takes your mountain biking to new heights.
