The Bola SL 45R is a 45mm T1000 UD carbon road disc wheelset on proven DT Swiss 350 hubs for fast group rides and gran fondos.

Take a measured step up in speed and control: where a stock alloy set robs the finishing climb, the Bola SL 45R returns every watt. A mid-depth 45mm rim, modern width and proven DT Swiss 350s hubs make a durable, fast, versatile road upgrade.

Buying Guide.

Internal width - 21mm: 25-28c at 80-95 PSI for smooth tarmac race lines.

Internal width - 24mm: 28c at 75-90 PSI for all-road and rolling chipseal.

Internal width - 26mm: 28-32c at 70-85 PSI for rougher tarmac and light gravel comfort.

Max rider weight: rated to 110kg - check rider plus gear.

Same-depth series: the ULT 45R (~$698) uses in-house TPI-ceramic hubs and the ELT 45R (~$579) sits below; the SL 45R steps up to globally serviceable DT Swiss hubs.

Adjacent depth: the SL 50R adds aero on flats and rollers - choose it for wind-cheating straight lines, the 45R for calmer crosswind manners.

Target Audience & Usage Notes.

For road racers, gran fondo riders and daily trainers wanting DT Swiss serviceability.

Max system weight 110kg; disc road/gravel frame required.

Not for heavy off-road or extreme gravel.

The Ride That Awaits.

Clip in and feel the paceline hold you - the rim hooks the wind on every drag, the DT Swiss hub clicks out clean, dependable answers. The bunch you used to lose now you drive; the finish climb loses its teeth. Free shipping and a 3-year rim / 2-year wheelset warranty with crash replacement make waiting the only risk.

Trade-offs & Considerations
Aero vs Crosswind: The 45mm depth saves about 2.5W versus a 35mm rim at 40km/h; at 10 degrees of yaw it is a balanced all-rounder, calmer in gusts than a 50mm-plus build.
Weight vs Stiffness: The T1000 layup saves about 40g versus a T800 build at 45mm (plus or minus 5g); lateral stiffness stays within 3%.
Tire-Type Trade-off: Tubeless clincher lets you run a 28mm tyre at lower pressure for comfort and rolling resistance, but sealant needs topping up every 3-6 months.
Sourcing & Delivery Trade-off: Standard stock ships in 1-3 business days while a custom internal-width build takes 7-15; at about $789 it is roughly one-third the price of comparable 45mm DT-hub wheelsets near $2,000.
Config Ladder: DT Swiss 350 with a 36T steel ratchet is standard; the in-house BL ceramic ULT 45R is about $698 and cuts about 1.5W of friction; the internal bed is selectable at 21, 24 or 26mm.

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
How does this 45mm deep rim handle crosswinds on fast descents?
An optimised 45mm profile keeps steering torque predictable at 10°–15° yaw, so high-speed descents stay planted.
Do these rims accept standard clincher tyres, and what is the pressure limit on hookless?
Hooked rims fit standard clincher tyres directly, with or without tubes. For hookless rims, per ETRTO, tubeless tyres 28c and wider must not exceed 72.5 PSI (5.0 bar) to prevent unseating.
Which tyres should I run, and at what pressure?
On the 21mm bed run 25-28mm at 80-95 PSI on tarmac; on the 24-26mm bed run 28-32mm at 70-85 PSI for chipseal/all-road. Tubeless ready.
How responsive is the ratchet when I pedal out of a coast?
The DT Swiss 350 runs a 36-tooth star ratchet for about 10-degree engagement, so power returns almost immediately after coasting - reliable and serviceable with basic tools.
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.
