Import 38mm Clincher Carbon Rim — Buy in wholesale FOB from Supplier in China

The 38mm clincher carbon rim from Workswell is a 700C road bicycle rim constructed from Toray T700 carbon fibre, designed for rim brake systems with a specified rim weight of 425 grams plus or minus 15 grams. The model designation WWC-R-38-23C denotes a 38mm rim depth paired with a 23mm external width, placing it in the all-rounder category suitable for varied terrain from flat roads to moderate climbs. The 14mm wide basalt braking surface is engineered for high temperature resistance, a critical feature for carbon rims used in prolonged descents where rim temperatures can exceed resin glass transition points. This rim format accepts clincher tyres with bead retention, offering easier roadside repair compared to tubular alternatives for competitive and enthusiast riders alike.

Toray T700 is a standard modulus carbon fibre with a tensile strength of approximately 4900 MPa and tensile modulus of 230 GPa, providing a balanced stiffness-to-weight profile for rim construction. The 23mm external width and 38mm depth represent contemporary dimensional norms for versatile road rims, though the internal width is not stated in the source data. Typical industry practice for rims of this profile suggests an internal width of 15-17mm, but buyers should confirm this dimension as it determines compatible tyre widths and optimal tyre shape. The basalt braking surface is a textured, heat-treated layer applied over the carbon substrate to improve friction consistency and reduce the thermal degradation that can affect resin-based composites under heavy braking loads.

Workswell positions this rim for wheel builders, bicycle manufacturers and upgrade-minded consumers seeking a carbon rim brake option without the premium pricing of aerospace-grade fibre variants. The clincher format broadens market appeal to riders who prioritise practicality and tyre availability. Buyers should note that rim brake carbon rims require compatible brake pads, typically proprietary compounds supplied by or specified by the rim manufacturer, to prevent premature wear or delamination. The exact MOQ, unit pricing, lead time and warranty terms are not stated in the available data and must be confirmed directly with Workswell before order commitment.

Workswell operates from Building 3, Yingfeng Industry Zone, at 34 Xiangyin Road in Nanlian, Longgang District, Shenzhen, China. The supplier holds a Harbor trust tier classification on the sourcing platform, with a response rate of 0.00 percent and no recorded average response hours, suggesting limited platform-mediated engagement metrics are available. The company focuses on carbon fibre bicycle components, with this 38mm clincher rim representing a product in their WWC rim series. The source description does not disclose founding year, employee count, factory floor area or annual production volume.

The supplier's product description emphasises material specification with Toray T700 carbon fibre and dimensional precision for the rim brake market. No ISO certifications, patent holdings, OEM client names or race team sponsorships are mentioned in the available data. Buyers should independently verify Workswell's manufacturing capabilities, quality control procedures for carbon layup and drilling, and their experience with export documentation for bicycle components. The Longgang District location places Workswell within Shenzhen's broader manufacturing ecosystem, but proximity to suppliers does not substitute for direct supplier qualification.
