Rennen Decimal Gearing is a breakthrough in gearing technology. They have developed Special Engineered Tooth profiles that allow us to manipulate the size of an existing gearing to make it slightly harder or easier depending on your needs for the track. Changing your gearing by Fractions of a tooth is now possible.

Now you have the ability to go down .1T, .2T or .3T

Or go Up by .1T or .2T (Ex. 43.7T, 44.2T)

Rennen Decimal gearing is offered in 104bcd, 110bcd or 19mm and across every gear size we make a total range of 22T-52T
