Bola SL 38RB Carbon Tubular Road Wheelset for Rim Brake — DT Swiss 350, Sapim CX-Ray, 700C, 38mm x 25mm

Attack a rolling stage, survive a long endurance ride, or sprint out of a technical criterium corner with a wheelset tuned for racing responsiveness. The Bola SL 38RB pairs a shallow, race-oriented rim depth with extremely low rotating mass so you feel every change in pace and terrain with direct control.

Bola SL 38RB Carbon Tubular Road Wheelset - Designed for competitive road racing

The 38mm-deep, 25mm-wide high-modulus carbon rim gives a blend of aerodynamic benefit and nimble handling suited to mixed parcours. At approximately 1,190g per pair (±20g), the set reduces rotational weight to improve acceleration and climbing response while the machined braking surface supports reliable rim-brake modulation.

Riders who demand precision and predictable behavior will appreciate the hand-built construction and component choices that prioritize serviceability and long-term performance under race conditions.

Why it fits your routine

• Balanced race geometry: 38mm depth offers aerodynamic gains on flats while remaining light enough for steep climbs, making these wheels versatile across road races, criteriums, and endurance events.
• Lightweight build: At 1,190g per set (±20g) the reduced rotational mass improves acceleration and lowers rider fatigue over long distances.
• Premium hubs: DT Swiss 350 hubs (100mm front / 130mm rear) use sealed cartridge bearings and are supported by a wide global service network for easier maintenance.
• Aero, durable spokes: Sapim CX-Ray bladed stainless spokes combine tensile strength, fatigue resistance, and aerodynamic advantage in a pro-level lacing pattern (20F radial / 24R; 2x drive, radial non-drive).
• Tubular tire fit: High-modulus carbon tubular rims designed for glued tubular tires provide a supple ride quality favored by many racers and pro teams.
• Hand-built precision: Each wheelset is trued and tensioned by hand to ensure spoke balance, long-term trueness, and straightforward serviceability.
• Race-legal and safety tested: Certified to EN14781 and ISO 4210 fatigue testing and accepted for UCI road racing, with a maximum rider weight rating of 100kg.
• Rim-brake compatibility: Machined brake track for rim calipers provides consistent braking feel when maintained with recommended cleaning practices.
• Service lifecycle: Component selection and hand-built assembly support predictable maintenance intervals and access to replacement parts over the wheelset lifetime.
