The Bola CE 40R is a 40mm T1000 UD carbon disc wheelset on a DT Swiss OEM 36T hub with foil carbon spokes, 1270g, for climbing-oriented road and gravel riding.
The climbing blade: 40mm, 1270g, DT Swiss ratchet. The Bola CE 40R pairs a 40mm T1000 matte rim (28-30mm external, 21-24mm internal) with a DT Swiss OEM 36T ratchet hub and foil carbon spokes — a climbing-oriented all-rounder, shallow enough to climb, deep enough to aero.
Buying Guide.
Internal width - 21mm: 28c at 70-85 PSI for smooth tarmac.
Internal width - 24mm: 32c at 50-60 PSI for all-road.
Max rider weight: rated to 105kg - the lowest in CE; heavier riders should consider the CE 45R.
Same-depth series: the EXP 40R (~$999) keeps steel CX-Ray spokes and the EXT 40R (~$1111) goes ceramic lighter; the CE 40R blends a DT ratchet hub with foil carbon spokes.
Adjacent depth: the CE 45R above adds aero - choose the 40R for climbing, the 45R for speed.
Target Audience & Usage Notes.
Disc-brake road and gravel frames, 12x100/12x142 thru-axle.
Max system weight 105kg (lowest in CE); heavier riders should consider the CE 45R (110kg).
Not for extreme off-road.
The Ride That Awaits.
The first climb confirms it - each steep pitch spins up without the burden you remember, the rim depth never once feeling like a weight. The descent holds its line through the gusts; the ratchet clicks clean out of every hairpin. Free shipping and a 3-year rim / 2-year wheelset warranty mean the climbs are about to get friendlier.

Trade-offs & Considerations
Aero vs Crosswind: A 40mm depth saves about 3.5W versus a 32mm rim at 40km/h and stays docile in 10° crosswind yaw — the all-day aero compromise; the 45R trades about 1.0W of calm for roughly 1.5W more aero.
Weight vs Stiffness: The T1000 layup with foil carbon spokes reaches 1270g (±5g), about 90g lighter than an equivalent steel-spoke build, while lateral stiffness stays within 3%.
Tire-Type Trade-off: The hooked bed runs tubeless clinchers from 28c to 32c; the 21mm bed suits 28c at 70–85 PSI and the 24mm bed suits 32c at 50–60 PSI for mixed road-gravel days.
Sourcing & Delivery Trade-off: Stock build ships in 1–3 business days at $1111; custom lacing or decal adds 7–15 business days.
Config Ladder: A DT Swiss 36T ratchet (10° engagement) with steel bearings is standard; a ceramic bearing upgrade saves about 1.5W friction for roughly +$120. Foil carbon spokes are already fitted; the deeper 45R adds about 1.5W aero for roughly 40g more.

Recommended Use Cases
Triathlon / Time Trial: IM and club TT fields reward deep-section aero; 40mm 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.

Freehub: Shimano HG / SRAM XDR (select at checkout)
Tire: Tubeless-ready clincher, 28-32c
Frame: 700C road / gravel disc frame

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.
Can a damaged carbon spoke be replaced at a local bike shop?
Yes. The spokes use a mechanical two-piece lock-up design (not bonded one-piece), and spare carbon spokes ship free with the wheelset. Any shop mechanic with a standard truing stand can swap a single spoke in about 10 minutes — no factory return needed.
Will carbon spokes snap suddenly in crosswinds or under lateral load?
Carbon spokes deliver ~3,800N tensile strength (above the ~3,000N of top steel spokes) with ~30% higher lateral stiffness. Potholes, hard efforts out of the saddle and everyday riding carry no metal-fatigue fracture risk.
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.
