The Bola CLA 45R 700C Carbon Disc Wheelset - a value 45mm aero tubeless set for endurance road training and light gravel, built in Toray T700/T800 carbon.

Take a single wheelset on long training rides, weekend sportives, and amateur races with confidence. The Bola CLA 45R pairs a 45mm aero rim with tubeless-ready carbon and a 54T ratchet hub - a value-focused upgrade for modern disc road and gravel bikes.

Buying Guide.

Internal width - 17mm: pair with a narrow 25-28mm race tire at 85-100 PSI for smooth tarmac race effort.

Internal width - 24mm: run a 28-32mm tire at 70-85 PSI for mixed roads and long fondos.

Internal width - 26mm: settle a 32-38mm tire at 55-70 PSI on rough chipseal and light gravel (ETRTO 2026 wide-rim guidance: a wider bed lets you run lower pressure for more grip and comfort).

Max rider weight: rated to 120kg system - check rider and gear before ordering.

Same-depth series: among mid-depth road wheels the ELT 45R adds a ceramic hub at $579, the ULT 45R adds CX-Ray spokes at $698, and the SL 45R moves to DT Swiss 350 at $789 - choose this CLA when price and plain reliability matter most.

Adjacent depth: the CLA 40R is lighter and calmer in gusts for climbing, while the CLA 50R adds flat-road aero - pick this 45R for the balanced middle.

Target Audience & Usage Notes.

For endurance riders, sportive-goers, and amateur racers wanting a durable, all-weather disc set.

Light gravel only where frame clearance allows.

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

The Ride That Awaits.

Picture a wet winter loop: the disc brakes modulate all day, and the tubeless rim lets you run lower so the rough tarmac numbs your hands a little less. It slips through group-ride pace without the crosswind drama of a deeper rim - a steady, workmanlike steed that never lets you down. Free shipping, VAT included, and a 3-year rim / 2-year wheelset warranty with crash-replacement cover mean the only risk is waiting another season.

Trade-offs & Considerations
Aero vs Crosswind: A 45mm depth saves about 4.0W versus a 35mm rim at 40km/h; at 10° yaw it sits between the 40R and 50R, giving steady training-day handling in crosswinds.
Weight vs Stiffness: 1380g (±5g) on the 28mm/21mm build; the extra rim depth adds about 10g versus the 40R, while lateral stiffness stays within 3%.
Tire-Type Trade-off: The hooked tubeless bed covers 25c–45c; the 17mm bed suits narrow 25–28c at high pressure, while the 24/26mm beds favour 28–38c at lower pressure for endurance miles.
Sourcing & Delivery Trade-off: Stock build ships in 1–3 business days at $468; custom width options add 7–15 business days.
Config Ladder: Enduro steel bearings standard; a ceramic upgrade saves about 1.5W friction for roughly +$100. The 54T ratchet gives 6.7° engagement; this training build keeps Pillar steel spokes throughout.

Recommended Use Cases
Road Racing: 2026 peloton standard runs 28-30mm tubeless on wide rims (TdF 2026 average ≈30mm); this 45mm 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.
Training & Daily Riding: Mid-depth versatility for group rides and race-pace training; ETRTO 2026 guidance recommends ≥28mm tubeless on 23mm+ inner beds for rolling efficiency.

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 45mm profile keeps steering torque predictable at 10°–15° yaw, so a daily training wheel stays composed on windy commutes and descents.
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.
