Cassette Question (2)

Triathlon Forum
1

I installed a new cassette and I’ve noticed that when the wheel is clamped onto the bike tight as it should be to hold the wheel in place there is some lateral play. I don’t have a torque wrench so I just tightend the lock ring down to what I thought was tight enough, trying not to over tighten it.

This was the first time I’ve tried to switch cassettes on my own, did I mess something up?

There really shouldn’t be any play. If it’s a 10 sp cassette did you remember the little spacer that goes behind the biggest gorup of cogs? If that’s not the cause, you probably didn’t tighten it down enough.

Play in the wheel or cassette?

Shimano or Campy?

What cassette, wheel and skewer?

Its a 9 Sp Shimano Ultegra cassette.

9 sp Shimano

Velomax Vista w/ stock skewer

the play is noticable with the wheel is firmly in the dropouts and clamped tight. So i’d say the play is in the wheel but I’m at work the wheel’s at home, so I can’t look at it right at the moment to say for 100% sure.

Sounds to me like one of the cog spacers is missing or one of the smaller, single cogs was not properly aligned/installed on the splines of the freehub body at the time you tightened it down which would cause it to have some lateral play. Take the lock ring off, take all the cogs/spiders off, and start over ensuring that the spiders are aligned/installed properly and that the cogs spacers are also properly installed between the individual cogs. Although Shimano recently revamped their site and I can not find the exploded view pdf for the CS-6500, herre is a link to the document from another site: http://www.gearshift.co.uk/acatalog/CS-6500.pdf

ECE,

I’m a horrible wrench but I do switch cassettes all the time. I did notice that my 9 sp ultegra cassette had an extra spacer on my mavic krysium wheels but not on my Alps. I also noticed that my new cassette did not come with this extra spacer. Both wheels work perfectly and I do not adjust the rear der. when switching…

Anyway - should be easy - take the old cassette and line up all the pieces - take the new cassette and line up all the pieces. Are they exactly the same? Put the new one on carefully as the other reply and see if it works. I do not think tightening the lock ring would make a big enough difference but I always use a torque wrench…
