Bola ST 45T DT Swiss 350S Carbon Road Wheelset – 45mm Tubular, Rim Brake, 1220g

On race day or during a hard training block, the Bola ST 45T wheelset gives you a blend of low weight and aerodynamic depth designed for riders who need responsive acceleration on climbs and stable speed on flats. Its 45mm tubular rim profile and a quoted weight of 1220g per set deliver tangible performance gains without the premium brand markup. Built around the reliable DT Swiss 350S hub system, this wheelset is intended for riders using rim-brake road bikes with tubular tires from 25c to 30c.

Bola ST 45T DT Swiss 350S Carbon Road Wheelset - Designed for road racing and training

Constructed from high-grade carbon fiber and certified to EN 14781, the Bola ST 45T pairs an aero-optimized 45mm rim depth with a light overall mass that reduces rotational inertia for quicker accelerations. The tubular-only design favors riders who prefer the ride characteristics and puncture protection profile of tubular tires, and the rim brake specification includes a carbon braking surface tuned for modulation under road calipers.

Rim width options allow tuning between a more aerodynamic, low-volume setup and a slightly wider, more comfortable tire profile. Riders seeking improved comfort can use the 28mm external rim option with higher-volume tubular tires run at lower pressures for a smoother ride on long days and rough roads.

Why it fits your routine

• Balanced aero and weight: 45mm rim depth combined with a reported 1220g ±20g set weight reduces drag while preserving climbing responsiveness compared with heavier wheelsets.
• Proven hub platform: DT Swiss 350S straight-pull hubs provide high-precision engagement and are serviceable for long-term use and workshop maintenance.
• Aero spokes: Sapim CX Ray stainless-steel aero spokes minimize drag and contribute to lateral stiffness for confident handling in sprints and attacks.
• Tire compatibility: Optimized for 25c–30c tubular tires with external rim widths of 25mm or 28mm to match rider preferences for speed versus compliance.
• Brake-specific engineering: Carbon braking surface designed for rim brakes to deliver predictable modulation and stopping power when paired with compatible calipers.
• Industry safety standard: Built from Toray-grade carbon composites and tested to EN 14781 for road use.
• Practical warranty: Two-year manufacturer coverage for defects in material and workmanship gives reassurance for regular use.
• Weight limit and use cases: Rated for riders up to 100kg and recommended for road races, mountain climbs, fast group rides, and upgrades where rim-brake tubular compatibility is required.
• Shop and fleet friendly: Factory-direct production and cost-effective positioning make this wheelset suitable for retailers or teams seeking performance without premium pricing.
