BXT CARBON PARTS

The BXT crankset is built for riders who won’t let a stiff frame be undermined by a compliant pedaling interface. In T1000 carbon with forged crank arms, it delivers high torsional stiffness — measured as deflection differential between arms under 200N load — ensuring every joule of pedaling effort reaches the chain without loss.

Robustness is built in at the fiber level: woven carbon reinforcement zones at axle interfaces and chainring mounts are identified through finite element analysis as peak stress concentration points. This localized reinforcement prevents the premature fatigue cracking that afflicts lower-grade carbon cranksets under sustained high-power use.

BXT crankset design mirrors the frame philosophy: clean lines, flawless finish, and compatibility with the most common BB and BCD standards (BSA, BB386, PF30, PF86). No adapters required for installation in any standard bottom bracket shell.

Available in 170, 172.5, and 175 mm arm lengths, the BXT crankset adapts to each rider’s morphology to optimize torque output and reduce knee and ankle joint stress. Compatibility with the most popular clipless pedal systems (Look, Shimano SPD-SL, Speedplay) is verified before each production run.

The BXT carbon seatpost absorbs vertical road vibration before it reaches the rider’s pelvis — a property aluminum seatposts cannot match at equivalent wall thickness. T1000 carbon stratified with ±45° fibers naturally filters high-frequency vibration while remaining fully rigid under pedaling loads.

Mechanical resistance is validated by load and fatigue tests conforming to EN 14782: 100,000 cycles at maximum rated load without visible deformation or degradation. These tests are conducted on each production batch before release to market.

The BXT seatpost features a matte or gloss finish, UV-resistant thermally bonded graphics, and a precision-machined aluminum clamp section that prevents rotation and marking under normal clamp force. A depth graduation marked every 5 mm simplifies installation.

BXT seatposts are available in multiple diameters (27.2 / 30.9 / 31.6 mm) and lengths (300–400 mm) to cover all standard seat tube specifications. Offset models allow the saddle to be set back for riders with longer femurs without requiring a frame change.

The BXT carbon saddle is designed for the rider who spends hours in race position: ultra-thin T1000 carbon shell, zone-differentiated high-density padding, and carbon or titanium rails depending on model. Total weight of a complete BXT carbon saddle comes in under 150 g.

Lightness of the BXT carbon shell is not achieved at the expense of structural integrity. Static load tests apply 1000N at the saddle center for 60 minutes without permanent deformation — a stricter protocol than EN 14781. High shell stiffness prevents flexion that creates variable pressure points depending on effort level.

High shell stiffness ensures a stable seating surface regardless of effort intensity: in sprint, endurance, and repeated accelerations. The BXT saddle does not alter its geometry under load, maintaining a constant pedaling position throughout the ride.

T1000 carbon resists UV exposure, moisture, freezing temperatures, and standard cleaning products. The shell surface is treated against water absorption to maintain weight and mechanical properties after wet rides.

The shell is tested in torsion, bending, and fatigue (200,000 load cycles simulating pedaling). Each test is documented and the report is available on request for competitively ordered saddles.

BXT carbon saddles deliver an exceptional compromise between weight, stiffness, and comfort: the shell filters road vibrations without creating hard pressure points, padding maintains its thickness after thousands of kilometers, and rails resist deformation under the most aggressive seatpost clamps.

The BXT carbon stem positions the rider relative to the handlebar and determines whether steering inputs are transmitted with precision. Its extension (reach) sets the bar distance, its angle adjusts torso inclination, and its stiffness ensures every bar impulse reaches the front wheel without loss to structural deflection.

T1000 fiber in BXT stems is the same grade as in premium carbon frames — maximum lightness, high resistance to impact and alternating bending, and consistent mechanical properties from part to part. A BXT carbon 90 mm stem weighs under 120 g.

These stems are engineered for extreme rigidity: zero play between stem and steerer after clamping, with precision-machined aluminum clamp plates that distribute handlebar clamping force across the full bar circumference to prevent fiber crushing.

Fasteners are titanium on premium models, eliminating galvanic corrosion risk at the carbon-metal interface in wet conditions. Each bolt is pre-torqued to BXT’s recommended specification before dispatch.

BXT uses advanced manufacturing methods: CNC-precision molds, post-cure at 120°C, and perpendicularity verification between steerer and handlebar axes. A 0.1° perpendicularity error translates to under 1 mm of asymmetry at a 44 cm wide bar.

Available in multiple extensions (60–130 mm) and angles (±6°, ±12°, ±17°), BXT stems allow fine position adjustment without frame changes. Compatible with all 31.8 mm handlebars and 28.6 mm (1-1/8 inch) steerer tubes.
