27.5 inch 650b DT Swiss Gravel G540 Disc, Halo Spin Doctor, 6-Bolt Hub Rear Wheels, 135mm QR, Shimano HG

These 27.5 inch 650b gravel bike rear wheels incorporate brand new black 32 hole DT Swiss G540 db disc rims, brand new black Halo Spin Doctor 6-bolt disc specific hubs, Halo silver stainless steel spokes and nickel plated brass nipples. After extensive testing DT Swiss have settled on a full 24mm as the perfect width for modern Gravel bikes. The added width gives better support to wide, 35c or larger tyres, allowing the use of lower pressures, enhancing grip & comfort whilst reducing rolling resistance & tyre flex under cornering. Robust, sleeved construction gives a great value package for a wide gravel rim with a suggested maximum system weight of 130kg. The rims can be used with or without tubes. The Spin Doctor mountain bike hub from Halo offers strong performance and is best suited to XC and trail bikes. With wide spoke flanges and sealed cartridge bearings the Spin Doctor offers a smooth and reliable drive, ensuring strength and longevity. The hubs are set for 135mm quick release – skewer provided. The rear Shimano HG freehub will take 8 to 12 speed Shimano HG MTB cassettes, or 8 to 10 speed Shimano HG road cassettes. The rims are 3-cross laced to the hubs with Halo silver stainless steel spokes and nickel plated brass nipples. Price includes insured and tracked Parcelforce postage.
