After much soul searching I decided to buy a new road bike and update my ageing mountain bike, not being flush enough to buy both new. As my rims are wearing out I need to replace the wheels (my first time). Being an older bike, I have a 7 speed XT cassette, and the wheels I am looking at take an 8/9 speed cassette, so I believe I will need to use a spacer. In realtion to this I would be much appreciated for some expert input on the following uncertanties:
1. Does the spacer go onto the hub before the 7 speed cassette? 2. Will I need to any other adjustments to the derailleur set up e.g. to stop the chain from slipping off the first gear? 3. Will performance be impacted at all by using a spacer?
Check that the drop out (over lock nut) distance is the same for both wheels, 135mm.
You could use an 8 speed cassette and no spacer, the 7 speed shifters will work the high 7 speeds of the 8 ok. I do this on the GF's 7 speed bike when I use 650c wheels. 😉
