从China供应商批发进口3 Spoke Carbon Wheel With Power Beam Spoke — FOB条款

The 3 Spoke Carbon Wheel With Power Beam Spoke from Workswell is a high-performance road and track wheelset built around a tri-spoke carbon rim with integrated Power Beam spokes. The rim uses Hi-TG carbon fibre prepreg with a glass transition temperature elevated beyond standard 180 degrees C epoxy systems, intended to withstand braking heat buildup on long descents. Rim height is 50mm with an external width of 25mm, placing it in the all-around aerodynamic category rather than a dedicated climbing or time-trial profile. The wheel is offered in both clincher and tubular variants, with front and rear weights ranging from 750g to 950g depending on configuration, and hub options from Chosen System with bearing counts varying between road and track builds.

The Power Beam spoke is a proprietary three-spoke carbon blade integrated into the rim structure rather than a tensioned wire spoke. This monocoque-style construction distributes load through the rim sidewall and spoke root junction, with the beam profile shaped for aerodynamic efficiency across yaw angles typical of road racing, approximately -15 to +15 degrees. Hi-TG carbon fibre refers to the temperature resistance of the epoxy matrix, with typical Tg values for this grade ranging from 200 to 230 degrees C, compared to 140 to 160 degrees C for standard carbon rims. The 25mm width is compatible with tyres from 23mm to 28mm nominal, with aerodynamic optima generally achieved at 105% of rim width. Brake track construction is not specified as rim or disc, though the 50mm depth and Hi-TG specification suggest rim-brake compatibility.

Target buyers include professional cycling teams, elite triathletes, and serious amateur racers seeking aerodynamic gain without the crosswind instability of deeper 80mm-plus rims. The track variant with reduced bearing count (2 front, 2 rear) suits velodrome competition with lower rolling resistance priorities and no braking requirements. When sourcing from Workswell, confirm which hub standard you require: Shimano or Campagnolo 10-11 speed freehub bodies are available for road builds, while track hubs use a fixed-cog thread. The supplier does not state whether skewers, rim tape, or brake pads are included, so clarify accessories before finalising purchase.

Workswell is based at Building 3, Yingfeng Industry Zone, No.34 Xiangyin Road, Nanlian, Longgang District, Shenzhen 518118, China. The company holds a harbor trust tier classification on the platform, with a response rate currently at 0.00% and no recorded average response hours. This profile suggests limited platform-mediated transaction history, so direct outreach to the Longgang facility is advisable to establish communication channels and assess technical competence before committing to a wheelset order.

The supplier's disclosed information covers product specifications in detail, including precise weights across four build permutations, but does not mention manufacturing certifications such as ISO 4210 bicycle safety standards, UCI homologation, factory quality audits, or crash replacement policies. Workswell's location in Shenzhen's Longgang District places it within the Pearl River Delta carbon fibre manufacturing cluster, where many small-to-medium composite workshops serve the cycling industry. Buyers should request factory inspection, rim impact test reports, and spoke fatigue data before placing a bulk order.
