S/C 30 tooth idler gear for A+ boxes using the 7/8" shaft.
Evolution Straight cut 23 tooth 1275 primary gear.
Ongoing development and investment of bringing parts up to date from yesturyear with current technology Mini Spares have introduced new EVO straight cut drop gears. With new 2 ring identification marks and part numbers they are not interchangable with previous drop gears as they have different profiled teeth with a shot peened finish for extra strength giving much more durability and quitness. More efficient as there is less power loss transmitted via gearbox and drop gears.
Achievable drop gear ratios when using our Evolution gears:
22 tooth primary - 30 tooth idler - 25 tooth input = 1.136-1
24 tooth primary - 30 tooth idler - 24 tooth input = 1.0-1
