I have just purchased my first single speed bike, A specialized Langster. I'm really enjoying the bike but would like to put a lower geared freewheel on it, currently its running a 16 and I'm looking to get a 14.
could anyone give me some advise on sizing etc? I've been looking at ACS claw freewheels, are they a standard size? not finding much help on the web...
Any help would be greatly appreciated
