I want to upgrade my suntour 6 speed bike with an aero wheelset. The wheelset Im looking at is compatible with 8/9 shimano cassettes.
If I use an 8 speed shimano cassette, from my understanding the issues I face with the upgrade are 1) rear wheel spacing of 130mm vs 126mm 2) index downtube shifter must be converted to friction.
Am I missing anything? such as will my 6 speed rear del. need to be swapped for a 8 speed compatible.
