(1/1)

motomagII:
right got 17t freewheel on me back and want to get good chainring for 3 piece whats the smallest i should go .how does it effect the speed /peddaling etc please cheers

sawzall:
BACK IN THE DAY MOST PEOPLE SEEMED TO USE 43-16 WHICH WORKS OUT TO 53.7 SO TO GET SAME SORT OF GEARING WITH A 17 YOU WOULD NEED A 45-46 WHICH WORKS OUT 52.9-54.1 WELL THATS WHAT MY BOOK SAYS ANYWAY :daumenhoch:

Rombloke:
you need to reach an average of 2.75.....this is done by dividing the front by the rear.

so working it backwards you need to go 17 x 2.75 = 46.75.

so you need a front sprocket as near to 46.75 as you can get....but gregg.....do yourself a favour....by a 16t freewheel and get a 44 front, its much easier.
