Bontrager G4 Team Issue MTB Tire

Rock gardens. Big hits. Bontrager's G4 Team Issue downhill tire is intended for very aggressive riding over difficult terrain in dry, rocky conditions.

Ramped leading edges on the center blocks, open tread design, and aggressive shoulder blocks keep the G4 rolling fast, and it quickly clears debris, and provides confident cornering. Dual-ply casing and condition-specific compounds provide additional support and control.
