Miche Rocking Sprockets?

I have one of those Miche quick-change track sprockets, and found that it sits pretty loose on the carrier, which gives a lot of play even when a lockring is done up very tight against the carrier.

This hasnt bothered me much, I just presumed it was supposed to be like that for some reason beyond my knowlwedge.

But just know a friend has called me up enlisting me (with the use of hammers) to help him get his perfectly working miche sprocket off (non-miche cheapo lockring notches wore out)

Its going to be pretty difficult to get it off, and in my opinion the rocking is not a problem.

But would like to know from others what the deal is with these? are they supposed to have some play?

I've not had any issues with mine - everything has fit together quite snugly. Sounds like perhaps notches on the carrier has worn down, possibly due to the lockring being poorly installed and leaving it all to wiggle around too much.

I think it's fair to say that as a general rule, any noticeable play on any part of a bike that should otherwise not move, is unlikely to be a good thing.

I have a miche quick change sprocket with a dura-ace lock ring on a System Ex hub. There shouldn't be any appreciable play with the lock ring tight. Is it the threads on the hub?

The drill for removing the sprocket carrier is; loosen the lockring half a turn, loosen the sprocket half a turn with a chain whip so that it tightens against the lock ring, repeat this process until the carrier is loose enough to unscrew by hand.

It's a bit tricky, but you shouldn't need to do it often, as the carriers last ages.

the play is pureley due to the sprocket being loose on the carrier.

Even if the lockring were to come into contact with the sprocket (it doesnt as the carrier is wider) is would only top it moving about side-to-side, but the issue is with it rocking fowards and backward , if you get the jist?

Well im off now over there, with a hammer in hand!

Like I said his lockring notches are worn out (think a formula one) so its going to be a mission to get it off, can see why his bothering personally. I dont really see the attraction with 'instant' engagement, im happy to have a slack chian too (as long as it doesnt pop off!)

Will, don't you find the DA lockring a bit small for the carrier system?

it hardly covers the lugs of the sprocket, I tried it but didn't want to risk it down t'track

I found those Miche sprockets hopeless on my Mercian, even when tightened to the max... Swapped it out for a Surly after a coupla weeks...

Never had any problems. If the chain line is good then there should be minimal lateral force on the sprocket. I've never taken t'Condor on t'track - opting for the hire bikes instead, although after all the faff I had with a hire bike last saturday I may need to answer the Fuji track-pro thats been calling me....

I have one on one of my bikes and there seems to be a bit of forward/backwards play too. I guess eventually this is going to wear down the carrier, which will then be a bugger to get off. I think it's a design thing rather than a installation issue though.

the sprockets are quick to change, just the carrier for them that's a bugger.
