Singlespeed & Fixed Gear - what kind of freewheel is this?

hello, i just picked up a new SS bike. i'm not sure what kind of freewheel this is, though. i'm thinking it's probably some generic brand. it's not very smooth.

Forget the freewheel, I'll take the hub.....:p

That hub deserves a fine track cog.

Hahahaha!

don't i know it! every time i coast, i cry.

there's no way to make it fixed, right?

Just take it to your LBS and have them remove it.

Get a good track cog and an Italian threaded lockring (Campy or equivalent)

i thought hubs could only be fixed or free, not both at the same time (exept for flip flop). i thought they had a different threading for each type of bike (fixed or SS).

a freewheel can be threaded onto a fixed hub because the threading is the same. The only difference is the reversed lockring threading which you wouldn't have to worry about with the freewheel.

What you've got there is a very nice sheriff's star Campy track hub. It just so happens to have a freewheel/single speed cog on it. You can remove that and install a fixed cog and a lockring instead.

Do you have the matching front hub?

i knew they were the sheriff star hubs. that's why i bought the bike. btw - it came with a very nice crankset, too!

i'm glad to know that i can make them fixed! i originally wanted the bike to be fixed, but i thought that i couldn't switch the freewheel. this is making me very happy!

and yes, they are matching hubs. see here:

sweet score

Very nice groupo.
Out of curiosity, are the Campy logos on the cranks printed or engraved?

thanks guys. i couldn't believe how sweet the bike was! the previous owner said he used it for about 10 miles. no typo TEN! but then it sat for 10 years in his garage.

the crank has the logo stamped:

great find.

Looks like a generic BMX freewheel. Shimano makes a 4-prong tool that looks like it would work:

nice buy

I think an F6 park tool is the same kind of tool. That's a beautiful bike - and it does need a high quality cog back there. nice going!

To answer the original question...that looks like a Dicta freewheel. You can buy them for $9 or less. They are certainly not the best, but for the price you can't complain. If its not smooth, chuck it and replace with a fixed cog or new freewheel.

thanks mihlbach. i'll definitely be tossing it and putting a campy cog back there (if i can find one).

now i have to figure out the brake situation. . .

the top tube has holes for the rear brake cable. if i get rid of that brake and put one up front, how can i ensure that no water will get into those holes?
