i know this is going to be a stupid question but i want to make sure of the problem before i go and buy new parts.
i put a new chain on my mt bike the other day... went for a ride and had chain skip when i was only in certian gears and when there wasnt a lot of "pressure" on the chain. i thought it was a tight link etc. i checked and no bad link. i then put on a different rear wheel on .. no skip.
change cassette right? what do i look for on the cassette to see it its worn etc.
enjoying the off season.....

|it can be worn enough to skip without you being able to see it.
However, have a look at the profile of the valleys in the teeth. When worn, they will be uneven, worn away more on one side than the other.
95% certain to be the cassette though in your secnario - I think you can change with confidence.
Not a stupid question - most people learn about tooth wear that way.

|As the other post said, sometimes it is hard to see. However, if you can see it it will look like a slight hook to the back edge of the tooth. If it isn't too bad, you can take a small Dremel grinding burr and lightly grind each tooth on the offending cog slightly at the top corner of the back edge so the transition along the back edge of the tooth is smooth and not hooked. This often will make the cassette work and you don't have to throw away a whole cassette because one or two cogs have worn.|

|I'll bet they're the ones that you use most often. Those are the ones that will have the most wear.|

|no one could figure it out. I look really close as I sofl pedal with the bike on the stand I saw that the link where I put the pin was too tight. I had force the pin too tight into the hole and and it actually bend the link. I remove it ( the damage link also,good thing I had some play)
I install a new pin and this time I just drove it in just enough to touch the link, dint force it hard as b4 and problem sove. I am plumber by trade and is a rooky mistake to force and ramm things in so tight. I should had know better.
