Michelin E-Wild Rear Performance Line 29" Tire More Torque. More Trail. E-MTB riders know the rear tire works harder than on any analog bike. The extra torque from the motor loads the knobs under acceleration, the added weight stresses the sidewalls in corners, and the sustained speed on descents requires more braking traction that a standard trail tire was never spec'd to handle. The E-Wild Rear Performance Line is designed specifically for those conditions. A bi-compound tread puts GUM-X where efficiency and durability matter most, and a reinforced casing adds pinch resistance for the kinds of impacts that come with heavier bikes and higher speeds. It's a rear-specific tire that matches the demands of the motor rather than ignoring them. Features Rear-specific designation tread pattern and compound placement optimized for the braking, acceleration, and load demands of a motor-assisted rear wheel Bi-compound with GUM-X balances rolling efficiency in the center tread and durability under cornering and braking forces at the shoulder Reinforced casing delivers increased pinch resistance over the standard GUM-X Competition Line for added protection on technical and rocky terrain E-MTB rated construction handles the sustained speeds and motor torque of pedal-assist mountain bikes29" diameter fits current long-travel and trail e-MTB platforms | Michelin | E-Wild Rear Performance Line 29" Tire 29X2. 6, Magi-X/gum-X, 2X33 Tpi, E25
