A new mountain bike wheelset called MT68 will be offered by Shimano for 2013. The
front wheel of the wheelset weighs 910g and comes with a 15mm axle. Its rear wheel is a little heavier at 1050g and it has a 12mm quick release axle.
Both the front and rear wheels of the MT68 are set up only for Center Lock rotors. On the other hand, Shimano also offers a new SLX-level adaptor for this model. This will be very useful for those who want to go for six-bolt discs.
Designed with aggressive trail riders in mind, the 2013 Shimano MT68 Mountain Bike Wheels will come with 21mm-wide rims. Thus, the wheelset can accommodate tires that measure up to 2.5in and both its front and rear wheels use 24-butted spokes.
