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? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Hub threading

Okay, here's the scoop. This is the first time I've ever built a single speed. I'm using an old Ross Eurosport frame and have a "DNP Long Yih Co." freewheel. Unfortunately, it is attached to another wheel. I am a bit confused on which way to turn this thing to get it off of the hub so that I can unlace the spokes and then assemble it onto another rim.

I've read the conversion page at sheldonbrown.com and it mentions that the hub threads will be left-handed (backwards). Then I start searching over here and find posters mentioning that, when you first install the freewheel, pedal around a while to tighten it up and DON'T backpedal. These two scenarios seem to contradict each other, since pedaling would tighten down the freewheel in a right-handed direction.

So, which way do I need to turn this sucker to get it off?

Thanks.

sheldon is talking about the lockring threads on a track hub.
a freewheel hub has normal (lefty-loosey) threads.

A freewheel will be threaded normally righty tighty lefty loosey but the lockrings used for fixed gear are left hand threaded.....so if it is a freewheel spin it to the left to remove it

the hub you're using won't have the right (left) lockring threading though.

In summary:

Freewheels are threaded the normal way, if you are making a single-speed and not a fixed gear, then you don't need to worry about reverse threading with regard to your hub.

If you are making a fixed gear, then the cog will screw on normally, however the lockring will be reverse threaded. It's also VERY important to get both the cog and lockring REALLY tight. This is not an issue on the freewheel as no backpressure can be applied (The thing just coasts).

I think there might be some confusion over the term "freewheel" and "fixed gear" going on...
