Shimano WH-MT620 12 Speed Micro Spline Rear Wheel
The Shimano WH-MT620 12 Speed Micro Spline Rear Wheel falls into the SLX series which is the workhorse of the Shimano range. It provides similar levels of performance to the flagship models, only with a small weight penalty and without some of the fancy finishing and surface treatments that you might find at higher price-points.
These wheels have a Microspline freehub which is essential if you want to run a 12 speed Shimano cassette. The lightweight aluminium freehub uses smaller, more widely distributed splines that spread the load from the cassette more evenly than traditional HG models, which reduces the surface damage and gouging that the cogs can often cause on aluminium freehubs.
30mm internal width rims means that you can run wide tyres and the Centrelock rotor attachment allows for the use of Shimano's Freeza rotors which maximise the cooling potential of your brakes, keeping them feeling consistent under heavy, sustained braking.
