The fastest, lightest, most advanced road wheel Boyd Cycling has built, at just 1329g. The 55 Road Disc SL sits at the top of the Podium Series, engineered without compromise for riders who demand absolute performance. Every gram, layer, and detail has been optimised to deliver a wheelset that is brutally fast, incredibly responsive, and built to win.
At the core of the 55mm Road Disc SL is a next-generation rim built with T1000 aerospace-grade carbon fibre, a material reserved for the most demanding applications. This results in massive 140J impact strength, overbuilt for real-world riding conditions, an ultra-light 400g rim weight, and a ride quality that feels both precise and unshakably solid.
A subtle but powerful advantage is the 2.5mm rim offset. This design equalises spoke tension between drive and non-drive sides, creating a wheel that is stronger under load, more laterally stiff, and more responsive when accelerating.
Hub Technology:
The Grade 54 hubs feature a straight pull design for increased strength and improved wheel stiffness. The 54-tooth ratchet distributes load evenly across large, interlocking surfaces, delivering exceptional strength and durability under high torque. Maintenance is simplified with tool-free servicing and tool-free swapping of end caps and freehub bodies. The Enduro ABEC-5 LLU/LLB bearings provide exceptional precision and durability, ensuring the hub operates smoothly under demanding conditions.
