Hi,

I've got a shimnao hub which takes a screw on block lying around. Is this suitable for a fixed wheel? Do I just need a screw on sprocket?

Thanks

You can put a fixed sprocket on. You can also add a bottom bracket lockring. It will not be as secure as a proper track hub with a reverse-threaded lockring.

Google "suicide hub" for more info.

Like Landslide says +

1. A few drops of Loctite always helps
2. To tighten it remove the chain from the chainring and let it rest round the bottom bracket ( where it willl naturally fall) Tuck a loop of the loose chain under the chain on the newly fitted rear screw on sprocket and turn the back wheel with all your might to tighten. It sounds far mor difficult to do than it is, maybe someone else will elaborate, but the added leverage of using the rim of the wheel gets it far tighter than you'll be able to using any other method. Mines been on there for about 2 years and has been fine so far although I dont rely on it exclusively to brake. Good luck

Another Threaded Hub question

OK - so I've got an old lightweight 531 frame of suitable geometry, horizontal drop-outs, adequate wheels. Decided to go low cost "suicide hub" route - because I've got all the bits and anyway I don't know if I can handle a fixed ( I am a bit of an old dog to learn new tricks ;))

Only thing I've had to buy is suitable size fixed sprocket.

Said sprocket is flat one side, raised lip on the other (so that it's deep enough for the threads)

Question - does it matter which way round the sprocket goes? Flat side to the hub or raised lip to the hub? Or can I choose so as to adjust the chainline slightly?
