Wheels are always a critical decision for a bike because they're rotating mass, and they handle large amounts of stress. The decision is only amplified when we move from 26 inch wheels to 29 inch. It's a longer way from the hub to the rim, so companies like Shimano have to work harder to maintain stiffness without adding too much weight. Shimano has been slow to enter the 29er market for two reasons: 1/ they wisely wanted to be sure the market was here to stay, and 2/ they wanted to do it right. With the WH-MT75 Shimano XT 29R Centerlock wheelset, they nailed it.
These wheels benefit from trickle down technology from the fantastic XTR wheelset. They roll on the same internals that come with XT hubs, so they are plenty smooth -- thanks to the angular contact bearings -- and durable, not unlike all members of the XT family. The main differences are that the flanges have been altered to work with straight-pull spokes and the axles are a beefy 14mm 7075 T6 aluminum. 24 double-butted (14-15-14) spokes in each wheel are set up two-cross and evenly spaced, which adds significant lateral strength without adding rim weight. The spokes no longer hook onto the side of the rim and get adjusted at the hub, which means a lighter, shallower rim can be employed.
The disc-specific WH-MT75 Shimano XT 29R Centerlock wheelset is designed to work with Centerlock rotors. The wheels are tubeless compatible, and tires can also be mounted with tubes. Over locknut distance is 100mm in the front, 135mm in the rear. Both the front and rear wheels have labyrinth and contact seals protecting the angular contact bearings. The rear wheel is compatible with nine-speed cassettes, with a 11t minimum cog. The hollow axles are aluminum and come with aluminum-shafted quick release skewers. The hub shell is aluminum and anodized, and it utilizes the Centerlock rotor standard. 6 bolt rotors CAN be used, but require the use of an adaptor. The rim is 29” in diameter (622 x 19c ETRTO) and the rim width is 23.5mm. Both front and rear wheels have 24 stainless spokes and are affixed to the rim with red anodized aluminum nipples. |
