Cost? A cassette and chain aren't that much and you will be replacing them every couple of years anyhow. Buy the lock ring removal tool and chain whip so you can change them out yourself.[/QUOTE]

I have the tools to do the job and when I rode in Colorado I stayed away from the really big climbs because I knew my lungs would explode. I enjoyed myself immensely. I'm planning a trip to ride 6 gap and 3 state 3 mtn, Ga and Tn. the climbs are big and tough for a flatlander but the altitude isn't bad at all. I would just like to make a good go at it instead of a weak lame attempt. everyone I've talked to locally tells me how tough it is but also how much fun it is.
thanks
