Does anyone know off the top of their head?  I don't want to take mine off the bike...

I've just counted 25 teeth on a spare lever BUT there is a blank area around the fixing clamp so there would appear to be 31 serrations on the full diameter (assuming you want to cut a new set?)

I would have expected an even number 32? but I keep coming up with 31.

Thanks Paul, great info and good pic to count the teeth!

Not being convinced of the odd number, I've just been up into the loft and counted the teeth on my spare gearbox, which, of course, has a full compliment of teeth, and, sure enough, (after 4 countings), the answer is 31.

Paul.

Any chance you could measure the diameter of the gearbox shaft?

Hi,
measuring across the top of the teeth it's 13.6mm

Thanks!
