Tire and roller contact will eventually wear both your tire and the trainer roller. • M20-D is a tire drive model, so if you use M20-D with a knobby tire on BMX, a loud noise must occur. To avoid this problem, replace the rear tire to a slick pattern one.
Replace your rear wheel quick release skewer to the supplied one. Minoura guarantees the stability only when using the supplied skewer due to the coupling inner shape.

Please note too much and too less roller pressure will bring premature tire wear. Keep correct roller pressure and maintain the air pressure in correct level before using M20-D. TIPS If it's hard to tighten the knob bolt, lift up the Mag unit by hand then tighten the knob.
