Product Description

Roval Control Carbon SL Boost 29 Wheelset

Lightweight, yet tough and stiff, the Roval Control Carbon SL Boost 29" Wheelset is ready for the most extreme and aggressive cross country racing. The rim shaped is tuned to provide these attributes, and offers a supreme ride quality; the 25mm external width is incredibly fast rolling. With a Zero Bead Hook design, tubeless tyre installation is easy and increases resistance to impact. Hand-built and matched with CNC machined hubs with DT Swiss 240 internals means engagement is lightning fast, and the DT Swiss Competition Race spokes are strong and stiff. This is a race-ready wheelset that is made for modern trails.

Setting out to create the ultimate cross-country wheels, Specialized have developed the Roval Control Carbon SL Boost 29" Wheelset. Weight has been kept to a minimum at sub-1400 grams, with no compromise on strength, for performance over the roughest and rockiest trails.

The wide 25mm external rim width provides an optimised tyre profile for excellent traction and low rolling resistance, and the rim has been shaped for stiffness, weight and ride quality. The Zero Bead Hook design is extremely resistant to impact and makes tubeless tyre installation a breeze, while providing a better tyre seal against the rim. The light rim has lower inertia for fast, punchy accelerations.

Lacing the rim to the hub are 24 and 28 DT Swiss Competition Race spokes, front and rear respectively, that make these hand-built wheels incredibly strong. The hubs themselves have DT Swiss 240 internals, sealed bearings and a 54-tooth start ratchet to the rear for super fast engagement. This 110/148mm Boost variant has an increased width to the front and rear hub flanges for improved frame and fork clearance, and a stiffer, stronger and more durable overall system with minimum weight penalty.
