Understanding the BMC Fourstroke Series: A Legacy of Innovation

BMC, short for Bicycle Manufacturing Company, has a rich history rooted in Swiss engineering precision. The Fourstroke series, in particular, represents their commitment to creating bikes that excel in endurance racing. The Fourstroke FS01 29 XTR is the top-of-the-line model in this lineup, introduced around 2013 as part of BMC’s shift toward 29-inch wheels for better rollover and stability on rough terrain. This model builds on BMC’s Advanced Pivot System (APS) suspension, which provides 100mm of travel both front and rear, optimized for efficient pedaling without sacrificing traction.

What sets the Fourstroke FS01 29 XTR apart is its focus on the “Big Wheel Concept” (BWC), a geometry philosophy that pairs a slacker head tube angle with shorter chainstays and stem for enhanced handling. This design ensures the bike feels nimble on climbs while remaining stable during descents. Riders often praise its ability to handle more challenging trails than typical XC rigs, making it ideal for events like the Trans-Sylvania Epic or long-distance adventures.

Design and Build Quality: Carbon Fiber Excellence

At the heart of the Fourstroke FS01 29 XTR is its carbon fiber frame, weighing in at approximately 2,040 grams including hardware and shock. This lightweight construction is achieved through high-modulus carbon layups, resulting in a stiff yet compliant chassis that absorbs vibrations without flexing under power. The frame features internal cable routing for a clean aesthetic and improved aerodynamics, along with a 142x12mm thru-axle rear dropout for precise wheel alignment and quick changes.

The suspension setup is handled by Fox components: a Float CTD Adjust FIT Factory Kashima fork up front with 100mm travel, and a matching Float CTD Factory Kashima rear shock. The CTD (Climb/Trail/Descend) system allows riders to adjust damping on the fly, locking out for efficient climbing or opening up for plush descents. This versatility makes the Fourstroke FS01 29 XTR adaptable to various terrains, from smooth fire roads to rooty, rocky paths.

Component-wise, the “XTR” in the name refers to Shimano’s top-tier XTR groupset, which includes a 3×10-speed drivetrain with a 42/32/24-tooth crankset and an 11-36 cassette. This setup provides a wide gear range for tackling steep inclines and high-speed flats. Braking is managed by Shimano XTR disc brakes with 180mm IceTech rotors front and rear, offering modulation and power that’s reliable even in wet conditions.

Wheels are another highlight: The bike rolls on 29-inch DT Swiss XR 1501 Spline wheels, known for their durability and low rotational weight. Paired with Continental X-King tires (typically 2.2-inch width), they provide excellent grip and rolling efficiency. Finishing kit includes Easton EC70 carbon handlebars, stem, and seatpost for further weight savings and vibration damping.

Overall build weight hovers around 23-24 pounds, depending on size, which is impressive for a full-suspension bike of this era. Available in sizes small, medium, and large, the Fourstroke FS01 29 XTR caters to a range of rider heights, with geometry that promotes an aggressive yet comfortable riding position.

Performance on the Trail: Speed Meets Versatility

When it comes to real-world performance, the Fourstroke FS01 29 XTR shines in cross-country scenarios. Its APS suspension design minimizes bob during pedaling, allowing you to hammer up climbs with minimal energy loss. Reviewers note that the bike accelerates quickly, thanks to the stiff frame and efficient power transfer, making it a favorite for race starts and sprints.

On descents, the 70-degree head angle and 100mm travel provide confidence-inspiring stability without feeling sluggish. The 29-inch wheels roll over obstacles with ease, reducing fatigue on long rides. Testers have described it as “more capable than your average XC race rig,” handling technical sections like drops and roots better than expected.

In terms of handling, the short 445mm chainstays and 80mm stem (on larger sizes) make the bike agile in tight corners and switchbacks. This geometry strikes a balance between race-oriented efficiency and trail fun, appealing to riders who want a bike that excels in competitions but doesn’t feel limited on weekend adventures.

One potential drawback is the 3×10 drivetrain, which, while reliable, might feel outdated compared to modern 1×12 setups. However, for its time, the Shimano XTR components offer crisp shifting and durability that’s hard to beat. Braking performance is stellar, with the IceTech rotors dissipating heat effectively during prolonged descents.

Riders in reviews often highlight the bike’s endurance capabilities, noting how it maintains composure over multi-hour rides. If you’re into events like epic stage races or all-day explorations, the Fourstroke FS01 29 XTR won’t disappoint.

Pros and Cons: Weighing the Strengths

Like any bike, the Fourstroke FS01 29 XTR has its highs and lows. Here’s a balanced look:

Pros:

• Lightweight and Stiff: The carbon frame and high-end components keep weight low while maximizing efficiency.
• Versatile Suspension: Fox CTD system adapts to different riding modes seamlessly.
• Excellent Handling: BWC geometry provides agility and stability for both racing and trails.
• Premium Components: Shimano XTR and Easton parts ensure reliability and performance.
• Endurance-Focused: Ideal for long rides with minimal fatigue.

Cons:

• Price Point: At $6,500+, it’s a significant investment, though justified by the spec.
• Outdated Drivetrain: 3×10 might require more maintenance than modern 1x systems.
• Limited Travel: 100mm suits XC but may not suffice for aggressive trail riding.
• Availability: As an older model, finding new units could be challenging; used market is key.

Overall, the pros far outweigh the cons for dedicated XC enthusiasts.

How It Compares to Modern Alternatives

While the Fourstroke FS01 29 XTR is from 2013-2015, it holds up well against newer bikes. For instance, compared to the current BMC Fourstroke 01 (which features updated geometry and 1×12 drivetrains), the older model offers similar efficiency at a potentially lower used price. Against competitors like the Specialized Epic or Scott Spark, it stands out for its Swiss precision and balanced ride feel.

If you’re upgrading from a hardtail, the added suspension will transform your experience on rough terrain. For those seeking more travel, consider trail bikes like the BMC Trailfox, but for pure XC speed, the Fourstroke FS01 29 XTR remains competitive.

Maintenance and Upgrades: Keeping It Fresh

Maintaining the Fourstroke FS01 29 XTR is straightforward. Regular suspension servicing (every 100-200 hours) keeps the Fox components performing like new. The carbon frame requires careful cleaning to avoid scratches, and checking pivot bearings annually prevents wear.

Upgrades could include switching to a 1×11 or 1×12 drivetrain for simpler shifting, or adding tubeless tires for better puncture resistance. Many owners report the bike’s durability, with frames lasting years under proper care.
