I have a mountain bike which is quite used. The chain has been slipping so I ordered a new Altus crankset. I was suprised to see the same type of radical un-even teeth on the brand new crank. Can someone explain this design to me and benefit - What else would cause my chain to jump and slip on the uphill ?
type of uneven teeth on any chainring, at least the large and middle rings, intended for use on a multi ring crankset. These are "shift gates", i.e. teeth that are profiled to allow for easier shifting. They are usually a bit shorter and rounded in profile, they allow the chain to more easilty slip on and off the chainring. Without them shifting is considerably rougher and slower. If your chain is skipping you likely have one of three problems, a worn out chain, a worn out cassette, or worn out chainrings. Or it could be a combination of all three. And with a well used bike it is likely all three. So BEFORE you install that new crankset I would highly recommend that you get a new chain and a new cassette and replace them at the same time. Otherwise you're going to wear those new chainrings on the nice new crank set into a worn out chain and end up right back where you started in short order.
