Sorry, I honestly look in the previous threads to find my answer, but what I find are 'hints' at an answer.
This will be the last question on 8 to 9 speed conversion (from me anyway).
My Marinoni is 1998 Shimano 105 - 8 speed components. Hubs are Ultegra.
First of all, the STI shifters are on the way out, since i cannot buy 8 speed shifters I have been looking at a new pair of 9 speed STIs on ebay.
Second, since I need new transmission (chain, cassette & rings) anyway, I thought why not upgrade to a 9 speed. Problem is - I want to keep cost down (HAH!!) and use my 8 speed front and rear derailler.
Sooo, is there enough travel on an an 8 speed rear derailler to use with a 9 speed cassette?
Can I put a 9 speed cassette on an 8 speed Ultegra hub?
My first guess is YES to both questions above, but I always get caught with my pants down about something when I upgrade.
What am I missing?
