Bola 32in (696mm BSD) asymmetric U MTB rim, 36/30mm, hookless, 350/450g, tubeless, trail/enduro.

The Big-Wheel Hoop

A 32-inch (696mm BSD) asymmetric U-shaped rim—36mm external, 30mm internal—for trail, enduro and freeride. Toray UD carbon; hookless tubeless.

Buying Guide.

Weight tier - Superlight ~350g: for trail racers and XC-adjacent riders who chase climbs and trim rotational mass, at the cost of a thinner impact margin.

Weight tier - Standard ~450g: choose it for enduro, freeride and rougher trail where rocks outweigh grams; it laughs off the hits the superlight would flinch at.

Internal width - 30mm: pairs with wide 2.3-2.8in trail tires at low pressure for grip on roots and loam.

Same family - the Bola 29er 36x30 wave rim is the 29in cousin; choose this 32er only if your frame clears the bigger wheel and you want the largest rolling hoop.

Target Audience & Usage Notes.

Trail, enduro, freeride, bikepacking.

Not road.

The Ride That Awaits.

Build it up, roll it into the trees, and you will find the big 32in hoop tracks roots and rock gardens with a confidence that borders on the theatrical - the hookless bed holding fat rubber at a whisper of pressure while the offset keeps the wheel true under hammering. Land that drop, hear the carbon thump, and trust it. A 3-year rim warranty and free shipping turn hesitation into a booking.

Trade-offs & Considerations
Aero vs Crosswind: This is a 30mm trail rim, not an aero section: aerodynamic gain is irrelevant at MTB speeds, and the shallow depth keeps steering neutral in gusts while the asymmetric offset addresses rear spoke-tension balance under disc braking.
Weight vs Stiffness: The 350g superlight layup saves about 100g versus the 450g standard rim (±5g); the standard layup is more robust for aggressive enduro and freeride, while the superlight build rewards faster trail riding.
Tire-Type Trade-off: The hookless bead runs tubeless 2.3-2.8 inch tyres at 20-35 psi for grip and pinch-flat resistance; hookless demands tubeless-ready tyres and respects a pressure ceiling.
Sourcing & Delivery Trade-off: Stock drilling ships in 1-3 business days at $320; a custom spoke count or build adds 7-15 business days and a roughly $40-80 premium.

FAQ
Do I get a bare rim here, or is it built up with a hub and spokes?
It's a bare carbon rim — no hub, spokes or nipples. Take it to any wheel builder to lace it to your own hub; we can also supply a built wheel on request.
What spoke drillings are available, and which brake type is this rim rated for?
Spoke drillings and brake rating depend on the build option, selectable at checkout. If you plan to lace your own wheel, confirm the drilling and brake type with Bola before ordering so the rim matches your hub and frame.
What spoke tension can I safely build to — will the holes pull out of the carbon?
Drive-side / disc-side maximum tension is 130–140 kgf, with the non-drive side adapted to match; the spoke holes are locally reinforced inside the carbon layup to prevent pull-out cracking.
Will the rim crack on rock gardens or bottom-outs at low pressure?
The bead area uses a thickened impact-reinforced layer; impact testing passes >60J extreme impacts (above the ISO 30J standard). Inner widths of 30mm accept wider tyres, which deform to absorb shock at low pressure.
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, and delivered to your door with no extra payment to customs or the courier.
