Frequently Asked Questions
Are the Bola EXT 45R carbon wheels suitable for both road and gravel cycling?
Yes, the 45mm rim depth and optimized 21/24mm internal width support both road and gravel use with 28–32c tubeless-ready tires. Riders report balanced handling in variable terrain and consistent durability due to certified materials.
How does a 1170g wheelset affect climbing and speed?
The sub-1200g weight with carbon aero spokes lowers rotational mass for fast acceleration on climbs and steady high-speed cruising. Real-world feedback shows solid performance across rolling terrain and race conditions.
Is the hub system reliable for long-term, all-weather riding?
The BL180 CNC aluminum hub uses a 54T ratchet design with TPI ceramic bearings. This setup provides rapid engagement, efficient power transfer, and has undergone ISO 4210-7 safety testing for long-term durability—even in wet weather.

Bola provides a 24-month limited warranty covering rims, hubs, and spokes for manufacturing defects. All wheels meet ISO 4210-7 and REACH standards, and after-sales support is included for both B2C and B2B customers.
