My current chain has been in use for 6,000+ miles. It's started jumping to a lower cog on the cassette during hard climbs. It's probably stretched and may have damaged the teeth on the most often used cog, hence the unexpected shift.
I have two questions about putting things right.
1. I'm considering buying the Park chain checker to keep this from happening again with a new chain. Is it foolproof in detecting chain wear? That's important given my fool factor.
2. Is there a reliable way to decide if the cog (or whole cassette) should be replaced? Eyeing the teeth won't cut it...keep that fool factor in mind. It's an XT, if that's a consideration.
Thanks.
