700c Asymmetric Carbon Rim 35mm — 24mm Inner Tubeless-Ready
700c Asymmetric Carbon Rim 35mm — 24mm Inner Tubeless-Ready
Couldn't load pickup availability
The Bola 700c asymmetric carbon rim — a 35mm-deep, 24mm-internal hoop (330-400g) built for gravel, cyclocross and all-road.
An asymmetric spoke bed equalizes tension for stiffer, longer-lasting wheels under disc load. At 35mm deep and 24mm inner, this Bola rim balances aero with crosswind calm for mixed surfaces.
Buying Guide.
Weight tier - Extreme Light ~330g: the Ultralight race build - for gravel racers and gran fondo climbers who want the lightest hoop.
Weight tier - Ultralight ~350g: the fast middle - a few grams more for training without losing the climb.
Weight tier - Superlight ~370g: the race-and-training balance.
Weight tier - Standard ~400g: the Light-grade durability build - rougher roads and loaded riders who want margin.
Internal width - 24mm: a balanced gravel/all-road channel that beds 27-42mm tires at moderate pressure - choose it for mixed surfaces rather than deep aero.
Same-family: the 30mm gravel rim ($310) is shallower and comfort-focused; the 40mm gravel rim adds aero on fast sectors.
Rated to a 105kg system weight.
Target Audience & Usage Notes.
Gravel racing, cyclocross, gran fondo and training.
Max system weight 105kg; not deep-aero racing; disc only.
The Ride That Awaits.
Drop the tire pressure and feel the gravel disappear under you - the offset bed holds tension true on chipseal and settles fast in crosswinds. It tracks predictably over rough miles, staying round where lesser hoops go out of true. Choose your weave and layup; a 3-year rim warranty and factory-direct shipping mean you simply ride.

Trade-offs & Considerations
- Aero vs Climbing: At 35mm depth, you get aero gains with moderate weight penalty. Choose Superlight (370g) for climbing, or Standard (400g) for all-around.
- Weight vs Durability: The weight tiers trade durability: Extreme Light at 330g is best for racing but less robust, Standard at 400g is more durable for training.
- Tire Volume vs Speed: 24mm inner width allows tires up to 50mm for grip, but narrower tires (25-28mm) are faster on pavement, sacrificing some volume.
- Crosswind vs Aero: 35mm depth balances crosswind stability and aero efficiency, unlike deeper rims that are twitchier in gusts.

FAQ
What tire sizes are compatible?
The 24mm inner width supports 32-50mm tires, ideal for gravel and cyclocross. For road use, you can go down to 25mm, but the rim is optimized for wider tires.
How do I set up the rim tubeless?
The rim is tubeless-ready, so you can install tubeless tape, valves, and sealant. Use a Presta valve, and it should hold low pressures without issues. Ensure the tire bead seats properly.
What are the weight savings compared to aluminum?
With weights starting at 330g, you can save over 200g per rim compared to typical aluminum rims, which weigh around 450-500g. This reduces rotational weight for faster acceleration.
Can I build a custom wheelset?
Yes, the rim is compatible with standard 700c disc hubs and can be laced with any spoke pattern. Choose the weight tier that suits your needs, and consider the asymmetric profile for better spoke tension balance.
How do I inspect for damage?
Regularly check for cracks, delamination, or impact damage. Look for soft spots or unusual sounds. If you hit a big pothole, inspect carefully. Carbon rims can be repaired if damage is minor.
