The Bola CLA 50R 700C Carbon Disc Wheelset - a versatile 50mm aero tubeless road/gravel set at entry price, built in Toray T700/T800 carbon.

Swap to a wheelset that widens your riding options: the Bola CLA 50R brings a 50mm aero rim and modern wide-rim choices so you ride fast on tarmac and confident on gravel without changing wheels. Tubeless-ready Toray T700/T800 carbon keeps mass competitive for long, mixed-surface days.

Buying Guide.

Internal width - 21mm: run a 28mm tire at 75-90 PSI for fast tarmac group rides.

Internal width - 24mm: cup a 30-32mm tire at 65-80 PSI for mixed roads.

Internal width - 26mm: settle a 35-45mm tire at 50-65 PSI on rough chipseal and gravel.

Max rider weight: rated to 110kg system - a touch lower than deeper sets, so confirm rider and gear before ordering.

Same-depth series: among its mid-depth road tier the ELT 50R adds a ceramic hub at $579, the ULT 50R adds CX-Ray spokes at $698, and the SL 50R moves to DT Swiss 350 at $789 - choose this CLA for broad aero on a budget.

Adjacent depth: the CLA 40R is lighter for climbing and the CLA 45R a touch shallower - choose this 50R when flat-to-rolling aero and a wide tire range are the priority.

Target Audience & Usage Notes.

For riders splitting road and gravel on one 700C set.

Not for heavy climbing - the depth favours flat-to-rolling speed.

Requires 12x100/12x142 thru-axles and Center Lock rotors.

Max system weight 110kg.

The Ride That Awaits.

A gran fondo that opens on smooth tarmac and dissolves into crushed limestone is this wheel's natural stage - it holds speed over the ripples and snaps back the moment you stand to climb. One set, two worlds; the ride asks you only to pick the line. Free shipping, VAT included, and a 3-year rim / 2-year wheelset warranty with crash-replacement cover mean your mixed-surface season starts the day you order.

Trade-offs & Considerations
Aero vs Crosswind: A 50mm depth saves about 5.0W versus a 40mm rim at 40km/h; at 10° yaw side-wind reaction is noticeable on open roads, so windy-region riders give up about 1.0W for the 45R's calmer steering.
Weight vs Stiffness: 1420g (±5g); the deeper rim adds about 50g over the 40R, while lateral stiffness rises roughly 5% from the taller section.
Tire-Type Trade-off: The hooked tubeless bed covers 25c–50c; the 21mm bed runs 28c at 75–90 PSI and the 26mm bed runs 35–45c at 50–65 PSI.
Sourcing & Delivery Trade-off: Stock build ships in 1–3 business days at $468; custom builds add 7–15 business days.
Config Ladder: Enduro steel bearings standard; a ceramic upgrade cuts about 1.5W friction for roughly +$100. The 54T ratchet gives 6.7° engagement; stepping to the premium 50mm series adds bladed spokes and ceramic bearings for roughly +$230.

Recommended Use Cases
Triathlon / Time Trial: IM and club TT fields reward deep-section aero; 50mm profile minimises drag on flat-to-rolling courses where aero dominates climbing.
Aero Road Racing: Fast flat road races and crits on disc frames; 2026 WorldTour teams run 28-30mm tubeless — pair the inner bed accordingly for rolling speed.
Race-Pace Training: Open, fast courses where holding aero position pays off; stable crosswind handling builds confidence before race day.
