Pro-Line 12mm hex adaptors & Blockade pre mounts
Pro-Line have released these aluminium 12mm Front and rear clamping hex adapters for the B4.1. If you just converted your B4.1 to 12mm hexes, then Pro-Line’s clamping hexes are a must have for all serious racers. These hexes clamp on to the axle and will not fall off when you change tires like the plastic hexes. Made from high quality, aircraft grade aluminium so you know that they will last and stand up to the power of your B4.1. Pro-Line have also released their popular Blockade tire in pre mount form. Available in M2 (medium) and M3 (soft), they come pre glued to V2 white wheels.
