I want to replace the singlespeed freewheel on a wheel I'm going to use for my conversion. I was going to order a new one and then saw that there is metric and english threaded models. How do I figure out which one I need? The freewheel currently installed says "MAIN DRIVE 1/2x1/8 (c7)". I had hoped the "c7" was a model number of some sort that would shed light on the threading, but so far google has failed me. Any ideas?
This is good info, thanks, but I really was trying to find out what threading my current freewheel has before I buy another one. From some more poking around it looks as if it's 16 or more teeth then it's english threading, and less than 16 is metric. Does this sound correct?
unless its left hand drive all freewheels 16t and above are common thread I have had bad experience with Dicta freewheels and good luck with ACS, AC Racing, Shimano and even the classic Suntour unless I you really want to spend a lot of money on a White Industries buy an ACS
the freewheel that came w/ my Madison started making odd noises so the shop gave me a new one. Long story, but he couldnt replace it so i have it with me. Its the same generica "India" freewheel, same 18tooth, but it has a different letter-number on it. The one on the bike says D5 and the new one says C7. What does this mean?
It looks like like the heavy inner part might be "dished" differently.. but i don't see any dish specs online anywhere when buying new ones...
I hate Dicta freewheels they just don't feel right to me, do yourself a favor and buy an ACS Claws freewheel they are worth their cost, not the slickest out there (that honor goes to White Industries) but ACS freewheels feel a lot more solid engaging than a Dicta does
