Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer?

AC Racing 15t Freewheel rubbing hub

just got one of these from Harris Cyclery and installed it yesterday on my formula hub. haven't done a long ride with it yet just around the block. but after installing with the bike on the stand and then pedaling backwards the wheel started going backwards too. riding it it works how it should but you can feel on coasting that it seems kind of tight. it seems like the freewheel is too wide maybe or rubbing against the hub so it's super tight. Any one have one of these freewheels and experience this? is this anything to worry about? like would it mess the freewheel side of my hub up? i had a acs 16t freewheel on there right before and it worked fine no rubbing.

is the actual freewheel body rubbing? or is there drag in the freewheel bearings themselves? if it is just drag you could have the bearing nuts? i think too tight maybe not a 100% sure but on my old schwinn i had a problem similar to this and that is what it was.

just heard back from harris and this is what they said,

"Yes, on a few hub designs, the 15tooth body rubs against the hub. The unique design of the 15 means it has a wider body than the 16.

You'll need at least a 1mm freewheel/bb spacer. Most all bike shops will have these. You unscrew the freewheel, then put the spacer on first. It positions the freewheel slightly away from the hub body."

once i do this i'll report back and let you know how it went.

thanks

Thanks for the heads up. I installed mine and went out an did 32 miles on it; no issues.

I retract; I went back and checked if I move the pedals backwards and it rubs *barely*. Did you notice any difference with the 1mm spacer?
