The Bola CLA 40R 700C Road Carbon Disc Tubeless Wheelset - a light, versatile 40mm aero set for road and gravel, built in Toray T700/T800 carbon.

Ride faster on mixed surfaces with a wheelset engineered to balance aerodynamics, durability, and everyday usability. The Bola CLA 40R pairs a 40mm rim with tubeless-ready construction and a light ~1370g profile - a confident carbon upgrade without excess cost.

Buying Guide.

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

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 105kg system - confirm rider and gear before ordering.

Same-depth series: among its shallower road tier the ELT 40R adds a ceramic hub at $579 and the ULT 40R adds CX-Ray spokes at $698 - choose this CLA as the value all-rounder.

Adjacent depth: the CLA 50R adds flat-course aero, while this 40R stays lighter and calmer in gusts - the pick for riders who climb.

Target Audience & Usage Notes.

For road and gravel riders upgrading from alloy, training riders, and climbers.

Requires 12x100/12x142 thru-axles and disc brakes.

Max system weight 105kg.

Tubeless-ready; clincher-compatible.

The Ride That Awaits.

A rolling-hill loop feels almost easy: the shallow rim carries you over the rollers without crosswind chatter, and the lively pair makes every kick on the climb feel like a gift. Tubeless pressures down around 60psi swallow road chatter whole. Free shipping, VAT included, and a 3-year rim / 2-year wheelset warranty with 30% crash-replacement cover mean you upgrade today and feel it on the next ride.

Trade-offs & Considerations
Aero vs Crosswind: A 40mm depth saves about 3.0W versus a 32mm shallow rim at 40km/h, and stays calmer than the 50R in 10° crosswind yaw; stepping up to the 50R gains about 2.0W of aero but gives up noticeably more side-wind steer.
Weight vs Stiffness: The T700/T800 layup comes in at 1370g (±5g on the 21mm build); the higher 40R grade saves about 120g but adds roughly $110, with lateral stiffness within 4% of this base build.
Tire-Type Trade-off: The hooked bed runs tubeless clinchers from 28c to 50c; the 21mm bed caps near 90 PSI for narrow race tires while the 26mm bed trades max pressure for 38–45c volume and lower rolling resistance.
Sourcing & Delivery Trade-off: Stock build ships in 1–3 business days at $468; a custom width build adds 7–15 business days with little price change, so lead time is the main cost of a bespoke set.
Config Ladder: Enduro steel bearings are standard; a ceramic upgrade cuts about 1.5W of hub friction for roughly +$100. The 54T ratchet already gives 6.7° engagement; carbon spokes are not offered on this base series.

Recommended Use Cases
Road Racing: 2026 peloton standard runs 28-30mm tubeless on wide rims (TdF 2026 average ≈30mm); this 40mm section suits 40+ km/h racing and flat-to-rolling stages.
Gran Fondo / Endurance: All-day rides on modern frames designed around 30-32mm tyre clearance (Giant Propel, Cannondale SuperSix, Cervélo S5, 2026); wide 21mm bed pairs 25-32mm tubeless for comfort and speed.
Climbing / Hill Repeats: Shallow section accelerates quickly on steep gradients; pairs well with 28-30mm tubeless for all-round race duty.

FAQ
Will this wheelset bolt straight onto my Shimano groupset?
A Shimano HG freehub is fitted, so an HG cassette mounts directly; note at checkout if you run SRAM XD/XDR and we will fit the matching body.
What actually arrives in the box — rim tape, valves, spare spokes?
Each set ships tubeless-ready with rim tape, valve and spare spokes included, so you can mount tyres and add sealant without ordering anything extra.
How does the rim handle crosswinds on exposed descents?
An optimised 40mm profile keeps steering torque predictable at 10°–15° yaw, so even on long exposed descents the front stays calm and planted.
Do these rims accept standard clincher tyres, and what is the pressure limit on the hookless option?
Hooked rims accept standard clincher tyres directly. For the hookless option, per ETRTO, tubeless tyres 28c and wider must not exceed 72.5 PSI (5.0 bar) to prevent unseating.
Will I really pay no customs or VAT for delivery to the US and EU?
Yes. The Economy channel ships DDP — duties and VAT are fully prepaid by us, cleared in advance, delivered to your door with no extra payment to customs or the courier.
