But that 13 tooth freewheel will not go on a good old fashioned hub...  I made that mistake   :'(


I stand to be corrected, but I think a traditional flip flop hub has the smaller threaded area on one side of it which will accomodate the wee freewheels.

I think   :-\

You are right Rob, a normal freewheel only goes down to 16 t, but I thought 2020mad ment what is the smallest freewheel that goes on a hub that is not a casette hub, i.e a threaded one  :idiot2:

Perhaps we need more info  :daumenhoch:

Hmmm guess i won't be fitting 28T chainring tommorow then,  28-16 ratio a bit stupid.
Will have to start saving a bit more for some new wheels.

You need a 10 to run a 28 teeth sprocket but it various but nowt by much you can run a 10x28 ,29,30,31 most common on new rides are 13x36

ok the easiest way to work out gearing is to head for an average ratio of 2.75.
this is acheived by diving the front sproket size by the rear

i.e 44 / 16 = 2.75


so if you wanted to run a 28 tooth front, then that needs to be divided by the 2.75 which equals 10.18.....so as nana says you will need a ten tooth driver.

44/16
42/15
40/14
39/14
36/13
33/12
30/11
28/10
25/9
22/8

hope that helps....i feel nerdy now

haro, how do you do

the smallest freewheel you can use on normal size threaded hub is 15 http://www.alansbmx.com/product_info.php?products_id=1179
you will need a flip flop hub to go smaller than that
