RaceLab 35 CX Tubular Wheelset

Description

Race Day. Race Weight. No Compromise.

The RaceLab CX35 is a purpose-built tubular carbon fiber wheelset engineered for the demands of elite cyclocross. Light, responsive, and structurally precise, the CX35 is designed for racers who measure their season in barriers cleared, run-ups conquered, and the seconds gained when the course turns technical.

A 35mm rim depth strikes the optimal balance for cyclocross — shallow enough to remain composed in headwinds and crosswinds along open sections, deep enough to maintain speed through power stretches. Paired with a tubular tire system, the CX35 delivers the unmatched grip, low rolling resistance, and pinch-flat resistance that define top-level cross wheels.

Advanced Carbon Architecture

Constructed from high-modulus carbon fiber, the CX35 achieves a class-leading set weight of 1150g (±40g) — the lightest wheelset in the RaceLab lineup. The layup schedule is engineered for explosive responsiveness, maximizing lateral stiffness for sprint-out-of-the-saddle accelerations and the relentless pace changes of a 60-minute race.

Each rim is dynamically balanced during manufacturing, ensuring harmonized rotation at race pace and consistent performance lap after lap.

Hand Built. Precision Assembled.

Every RaceLab CX35 wheel is hand built in-house by experienced wheel technicians using only the highest quality components. Spoke tension is meticulously measured and balanced to exact tolerances, ensuring structural uniformity, long-term reliability, and consistent performance under race-level loads.

This deliberate, hands-on assembly process allows each wheelset to meet exacting standards of trueness, roundness, and tension balance — delivering a ride quality that is both precise and enduring.

Structural Reinforcement, Intelligently Applied

The variable-thickness nipple bed reinforces the spoke interface — the highest stress zone within any performance wheel. By increasing material only where required, durability is enhanced without compromising weight targets. This precision allocation of carbon ensures long-term structural integrity while preserving the lightweight character demanded by competitive riders.

Tubular Performance

The tubular rim bed is engineered for secure tire bonding and a clean, optimized profile. With a 28mm width, the CX35 is shaped to support the wide cyclocross tubulars favored by elite racers — delivering exceptional cornering grip, mud-shedding tread engagement, and the supple ride quality that only a properly mounted tubular can provide.
