Carbon wheels are the single highest-impact upgrade to a bicycle’s dynamics — lateral stiffness determines power transfer, aerodynamic profile influences top speed, and rotational inertia shapes acceleration response. BXT engineers its carbon wheels for each use case, from technical mountain biking to road competition.
Frequently Asked Questions
What rim depth should I choose for road riding?
For all-around use (training plus racing), a 38 to 50 mm rim depth is ideal. Beyond 60 mm, aerodynamic performance increases but crosswind handling decreases.
Are BXT carbon wheels compatible with rim brakes?
BXT offers wheels in rim brake version (with treated carbon braking surface) and disc brake version (tubeless ready). Check version compatibility before ordering.
What is the stiffness of BXT carbon wheels?
BXT wheels have a radial stiffness of 80 to 120 kg/mm depending on the model, measured under static load, ensuring predictable cornering and performance under maximum effort.
Can I use tubeless tyres on BXT wheels?
BXT disc brake wheels are tubeless ready. A dry fit requires rim tape and preventive liquid (30 to 60 mL). Rim brake versions are compatible with tubular or clincher with inner tube.
One of the key elements in the design of these wheels is lightness. The BXT carbon wheels are designed to be incredibly light, which allows a total reduction in the weight of the bike and an improvement in handling and performance. This light weight is especially important for mountain bikes, where every gram counts to tackle rough terrain and tough climbs.

BXT MTB carbon wheels absorb the specific stresses of off-road riding: rock strikes, torsional forces in banked corners, flex on landings. The low-profile rim with integrated tubeless bed allows running lower pressures without pinch flat risk, improving grip on loose terrain and reducing unsprung mass.
T1000 carbon construction allows thinner rim walls than aluminum at equivalent strength, saving weight while reinforcing spoke beds and nipple zones. High torsional rigidity ensures the wheel stays in plane under hard disc braking, preventing the deflection that reduces braking precision.
BXT MTB wheels are natively tubeless-compatible: valve inserts and rim tape are supplied pre-installed. Running 0.3 to 0.5 bar lower than tubed setup significantly increases the ground contact patch, improving traction on loose and rocky terrain while reducing the risk of square-edged rim impacts.
BXT MTB wheel finishing combines aesthetic quality with functional protection: UV-stabilized sidewall coating, individual runout verification before dispatch, and reinforced spoke hole inserts that distribute nipple tension across a larger area of carbon.
BXT CARBON ROAD WHEEL
BXT high-profile road wheels pursue two objectives: minimizing aerodynamic drag in straight-line riding and maintaining the lateral rim stiffness that resists deflection during sprints. The teardrop-section rim profile, calculated from wind tunnel testing, is optimized for wind attack angles from 0° to 15°.
The low weight of T1000 carbon BXT high-profile rims delivers a double benefit: less mass to accelerate in straight-line riding and less energy lost to rotational inertia during accelerations out of corners or up short rises — a measurable saving in races with frequent pace changes.
BXT road wheels use stainless steel spokes in a crossed pattern or carbon spokes depending on the model. Spoke heads are seated in anodized aluminum inserts that distribute nipple tension loads across a larger area of carbon rim, preventing spoke hole cracking under sustained load.
Each batch of BXT road wheels is certified through lateral and radial runout measurement, spoke tension testing, and a static load test at 1.5× maximum rated load. This data ships with each wheel ordered for competitive use.
T1000 carbon fiber delivers fatigue resistance significantly superior to high-performance aluminum. BXT wheels undergo 200,000 load cycles in laboratory testing before batch approval — a protocol that guarantees durability over thousands of competition kilometers.
Long-term performance of BXT wheels is maintained through design choices that resist degradation: consistent spoke tension distribution, rim geometry that resists deformation under repeated square-edged impacts, and surface treatment that holds up to UV exposure and road contamination.
BXT wheel design is built to function and look its best over time: thermally bonded graphics resist UV degradation for a minimum of five years, and polished rim sidewalls receive a surface treatment that facilitates tire mounting and resists corrosion. Available in multiple finishes for all BXT frames and third-party builds.
BXT CARBON TRACK AND TRIATHLON WHEEL
Track and triathlon disciplines impose distinct constraints on wheel design: no braking forces (fixed gear on track, disc-only on triathlon bikes), sustained high speeds, and maximum aerodynamic efficiency. BXT track and triathlon wheels are built around deep-section monocoque rims in T1000 carbon, optimised for low drag at yaw angles typical of outdoor racing conditions.
The monocoque rim — formed as a single carbon shell rather than a bonded assembly — eliminates the joint zones that concentrate stress under cyclic load. This construction allows thinner rim walls at equivalent strength, reducing rotating mass while maintaining the torsional rigidity demanded by velodrome banking and tight triathlon corners.
BXT rear disc wheels for triathlon are sealed-face carbon monocoques with a straight-pull spoke hub. The flat face eliminates the aerodynamic disturbance of conventional open-section spokes at speeds above 40 km/h, where aerodynamic drag accounts for more than 80% of total resistance. Front pairing with a 60 to 80 mm deep-section wheel delivers a coherent aero system without the crosswind instability of a front disc.
For velodrome use, BXT track wheels feature a specific spoke count and tension protocol — higher tension than road builds, with radial lacing on the front and cross-3 on the rear drive side — to handle the sustained lateral loads of banked corners and the peak torque loads of sprint finishes.
How much do BXT carbon wheels weigh?
BXT carbon wheel weight varies by model and rim profile. Entry-level all-around models (35 to 45 mm rim depth) typically weigh 1,350 to 1,550 g per pair. High-profile aero wheels (60 to 80 mm depth) weigh 1,500 to 1,750 g per pair. Track disc wheels are in the 900 to 1,100 g range for the rear disc alone. All weights are listed without rim tape, valve, or cassette.
What is the maximum rider weight for BXT carbon wheels?
BXT carbon wheels are validated up to a system weight of 110 kg (rider, clothing, and bike combined). This limit is set by the spoke tension protocol and the radial load capacity of the hub flanges, not by the carbon rim itself. Riders above this limit should contact BXT to discuss a custom spoke build with increased spoke count and tension.
How do I maintain BXT carbon wheels?
Carbon wheels require less maintenance than aluminum but benefit from systematic checks. After every 500 km of road use (or after each MTB session in wet conditions), verify spoke tension with a tensiometer and check lateral and radial runout with the wheel in a truing stand. BXT recommends re-tensioning spokes to specification after the first 200 km of use, as carbon rims undergo initial seating that releases tension unevenly across the build.
- Brake track (rim brake models): Inspect the braking surface monthly for wear groove depth. Replace the wheel when the groove reaches the wear indicator line printed on the rim sidewall.
- Cleaning: Use water and mild soap only. Avoid solvents, acetone, or high-pressure jets directed at hub bearings. Degreasers are safe on the rim surface but not on carbon spoke heads.
- Storage: Store wheels horizontally or hung by the axle. Avoid resting wheels on the rim for extended periods, as point loading on carbon can cause localised deformation over time.
Can BXT carbon wheels be repaired after an impact?
Minor spoke damage (broken spoke, bent nipple) can be repaired by any wheel builder with access to the correct spoke specification. Rim damage — cracks, delamination, or visible impact marks — must be assessed by a carbon repair specialist before the wheel is returned to service. BXT does not recommend riding a rim with visible structural damage, regardless of whether the wheel rolls true. A cracked rim can fail without warning under braking or cornering loads.
