The Bola EXP 50R is a 50mm T1000 aero road disc wheelset on DT Swiss 240s hubs with CX-Ray spokes, 1350g, for aero road and light gravel.

The aero road blade: DT Swiss power, 50mm depth. The Bola EXP 50R pairs a 50mm T1000 rim (28-32mm external, 21-26mm internal) with genuine DT Swiss 240s hubs and Sapim CX-Ray spokes — a dependable aero road wheelset that bridges to light gravel via tubeless-ready wide internal widths.

Buying Guide.

Internal width - 21mm: 28c at 70-80 PSI for smooth tarmac.

Internal width - 24mm: 28-32c at 65-78 PSI for rolling road.

Internal width - 26mm: 32c at 40-50 PSI for light gravel.

Max rider weight: rated to 120kg - the highest in EXP, suiting heavier builds.

Same-depth series: the PRO 50R (~$999) is lighter with ceramic bearings and the PRM 50R (~$888) is the value pick; the EXP 50R leans on a genuine DT Swiss 240s hub.

Adjacent depth: the EXP 45R below is calmer in crosswinds - choose the 50R for aero on flats, the 45R for composure in gusts.

Target Audience & Usage Notes.

Disc-brake road and gravel frames, 12x100/12x142 thru-axle.

Max system weight 120kg (highest in EXP).

Not for heavy off-road or severe gravel.

The Ride That Awaits.

Flat-out on the open road, the rim cuts the air while the DT Swiss hub clicks a steady rhythm between your efforts. You hold the bars, the group drags behind, and the rough cut-through softens when the tarmac ends. Free shipping and a 3-year rim / 2-year wheelset warranty mean the only regret would be delay.

Trade-offs & Considerations
Aero vs Crosswind: A 50mm aero rim saves about 5.0W versus a 35mm rim at 40km/h and 10 deg yaw, but crosswind steering is noticeably busier than the 40R; choosing 40R gives up about 1.5W for calmer handling.
Weight vs Stiffness: At 1350g the narrow 21-26mm internal bed keeps the set about 100g below a wide gravel 50mm (plus or minus 5g), with lateral stiffness within 3%; the deeper rim trades a little climbing ease for aero.
Tire-Type Trade-off: The 21/24/26mm internal channels run 25-50c tubeless; 21mm for 28c at 70-80 PSI, 26mm for gravel at 40-50 PSI.
Sourcing & Delivery Trade-off: Stock ships in 1-3 business days at $999; custom adds 7-15 business days and about a $100-150 premium.
Config Ladder: Hyper carbon spokes (EXT spec) save about 180g for roughly +$110 and add about 5 days; ceramic bearings are already fitted, and the 36T ratchet (about 10 deg) can be stepped to a 54T ratchet (about 6.7 deg).

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.

FAQ
How does this 50mm deep rim handle crosswinds on fast descents?
An optimised 50mm 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.
Are ceramic bearings durable in rain or rough conditions - do they need frequent service?
The bearings use dual-lip contact labyrinth dust/water seals. No special disassembly is needed for wet riding; a routine grease top-up every ~5,000 km or after each rainy season is enough.
Which tyres should I run, and at what pressure?
On the 21mm bed run 28mm road at 70-80 PSI; on the 24-26mm bed run gravel at 40-50 PSI. Tubeless recommended.
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.
