These triple clamps add enough width to allow the use of a 3+2 10X5 front wheel when running our DT Front Hub, axle/ spacers/ rotor adapter (all sold separately, This is for one set of clamps only 2PC). There is -2.5 degrees of rake built into the clamps which will tuck the front wheel back and help with steering the fatter tire. These are a universal fitment item for many uses. (They fit some KX450F with minor modifications, such as adding steering stops, they will also fit some CRF450R if you open up the stem holes, they also fit the Yamaha Tri Z stem with one thin spacer in top clamp). We have tested this product extensively and it works great! Note: You can also run an ATC200X front hub for an 11X6 front wheel. You are purchasing one top clamp and one bottom clamp.
