40T Pulley Recommendations: • Perfect for light weight riders and for wheels not bigger than 110mm • Works for heavy weight riders as well but we recommend not to go bigger in wheels than 100mm • 120mm Wheels + 40T = 37mph We do not recommend riding at such high speeds as it can result in serious injury etc. • The best setup for riding uphill can be achieved by using 97mm wheels
45T PulleyRecommendations: • Perfect for heavy weight riders especially with the 115mm wheels or other wheels with a diameter bigger than 100mm • Works for light weight riders as well and is suitable if you desire even stronger acceleration • The best setup for riding uphill can be achieved by using 115mm wheels or 110mm Wheels by Torque Boards. 85mm wheels can work but we recommend bigger wheels for bigger ground clearance.
