Bola 700C 88mm Hooked Tubeless Aero Carbon Rim | 27mm Wide TT Triathlon

A deep 88mm U-shaped hooked tubeless carbon rim engineered for time trial and triathlon racers who want proven aero speed at a factory-direct price.

Built for the Clock

When every second counts, the BOLA 88mm hooked tubeless rim delivers measurable drag reduction. Its full 88mm U-shaped profile, 27mm outer width and 20mm inner width are tuned for 25–36C tires, with a hooked ETRTO bead that seats reliably up to 125 psi.

Buying Guide.

Weight tier - Standard ~690g: the safe race-weekend choice, robust and happy to be bashed around the pits.

Weight tier - Superlight ~650g: take it for flat time trials where every gram of rotating mass counts; a small saving for a small margin.

Tire width - narrow bed: favor 25-28mm rubber for pure aero; step up to 32-36mm only when course comfort outweighs drag.

Brake - rim brake only: build it for a TT bike; it has no place on a disc frame.

Adjacent depth - for anything but a flat course, step to a shallower Bola aero rim; this is a straight-line weapon, not a climber.

Target Audience & Usage Notes.

Time trialists, Ironman and ITU triathletes, and wheel builders supplying flat-course racing customers.

Not recommended for steep climbing, technical descents, or heavy crosswind days.

Rider weight rating up to 125kg per manufacturer test data.

The Ride That Awaits.

Point it at the start ramp, drop your head, and watch the world flatten - that tall hooked section cheats the wind with a composer's discipline while you hold a tuck and the clock melts away. It wants the flat, the straight, the lone rider against the elements. A 3-year warranty with crash replacement means you can attack without looking over your shoulder.
