ULT-R – Bola's flagship T1000 road wheelset
The ULT-R series sits at the top of Bola's road lineup, using 100% Toray T1000 carbon fiber – the same high-modulus material used by pro-level aero wheelsets – for maximum stiffness-to-weight. Each wheelset is laced to BL100 straight-pull hubs with 54T ratchet engagement and ceramic bearings, and built with Sapim CX-Ray aero spokes for a balance of low drag and high lateral rigidity.

ULT-R vs ELT-R – quick guide
Both series share the same hub platform and tubeless disc construction. ULT-R uses T1000 fiber and CX-Ray spokes for the lightest, stiffest builds; ELT-R uses T800 fiber and Pillar aero spokes for near-identical aero performance at a lower price point. Choose ULT-R for racing and power-focused riding, ELT-R for all-round performance and value.
Every ULT-R wheelset ships tubeless-ready with tape and valves, rotor lockrings available on request, and carries the Bola two-year structural warranty.
