Interested what peoples expectations are for the xtr level of component...
I know there's a lot of variables...
The laymans guide for me has always been 3 chains at 500 miles off road,each chain fitted three times in order... =4500 miles ish.. and viola your Xtr cassette is dead! But has been drained of every last ounce of use...
Not the case it seems these days... The metal seems as soft as shit! and chains are just bollox....
