The Bola 700C 35mm carbon tubular rim - a light 28mm-wide U-shape glued-tyre rim for climbing and windy all-round road racing.
The featherweight climber's tubular: the Bola 35mm tubular is the lightest in the tubular family, a shallow rim built for riders who count every gram. Thirty-five millimetres of T700/T800 UD carbon, 28mm wide, sold rim-only.
Buying Guide.
Weight tier - lightest layup ~285g: the featherweight climber's pick - lightest in the tubular family, for lighter racers on summit finishes.
Weight tier - heavier layup ~340g: the durable choice - more layup margin for rougher climbs and heavier riders.
Max rider weight: rated to 105kg - check rider + gear before ordering.
Same-depth series: the 35mm asymmetric metric tubular adds offset stiffness; the 35mm U-shape tubeless is the tubeless road version.
Adjacent depth: the 40mm tubular asymmetric adds aero; the 30mm asymmetric tubeless is shallower still.
Target Audience & Usage Notes.
Target audience.: Climbers and riders in windy terrain on tubulars.
Rim-only.
Glue your own tyres; use carbon-specific rim-brake pads; respect 85 psi and 105kg.
Not for riders unwilling to glue.
The Ride That Awaits.
Cement a 25-28mm tubular, lace to a featherweight climbing hub, and feel gravity loosen its grip: 285g of rim, modest 35mm of aero, the glued tyre turning every climb into a conversation. The lightest race tool in your kit. Free shipping, a 3-year rim warranty and crash-replacement discount.
