Last autumn I got a new Cannondale Evo Six after five years with my Jamis Xenith and threeish full drive train rebuilds. This time I was determined not to leave my components on too long and get trapped into an old worn chain with the same rings. This spring I changed my chain for the first time after 2792kms. My heart was in my mouth when I heard the deadly chunk-chunk of a slipping chain (had I procrastinated too long by skipping a few wet weekends to do the change?) Well it slipped three times on that first ride then bedded in and has run smoothly ever since.
I've just ordered a new chain; my new chain is solid at 75% on my Park tool (bit of play at 65-70) so I reckon I have about a fortnight left in it. Now on another 2210kms. So I am happy I am keeping an eye on my chain. However, now I wonder how long I can keep my cassette going? I know some of you will say change the cassette with every chain, but we are not looking at pro team money here. And my second chain proved to me that changing the chain in time is vital. What do you reckon, will my current cassette (5002km) sustain me, when would you change this and crank?
