16 for me too, although if you're going to rie it distance a 15 will give you a better top speed

You will stuggle getting a 15T to fit new tuffs... Works with any brand 16 tooth or larger freewheels.  Also works with AC brand 15 tooth freewheels.

I can only see ACS, Dicta or shimano's in 16t (although there are some cheapy ones as well) If its going to be ACS, how will I know which size to get?
Thanks, guys :)

Compare left and right hand side of rear hub :daumenhoch:

There is quite a size difference so should be quite obvious but if you are going for a 16 teeth you wont go far wrong.  :4_17_5:

Tuffs have the larger size

Hub only has a thread on one side and looks to be the smaller version. I normaly get stuff on here or the bay as my local bike shop only do cheapo parts.


Glad I asked the question before just going ahead and buying one. Ive already had a nightmare getting a 28tpi bb for this build (1mancity2 helped me out on that) how about the suntour 17t freewheel??
Cheers, Jonathan :daumenhoch:

It is definately the larger on.  if it was my money I would go for one of these and stick to a 16 teeth  or else you will be pedalling quite fast.
