This is a fair question - does anyone know why they wouldn't work? > > Actually, given cost and availability, rather than rehabbing an 8, > wouldn't you be better off switching to 7 speed? > 7 & 8 sp cogs are close enough in thickness that either works for me. I'm now up to 5 7 sp cogs on my 8 sp. I had a couple of spare 7sp cassettes when my bike came with 8, and just pick up the odd 7 sp when I see one. Great good fun and I get to pick my own gearing, just like in the days of Uni-Glide. > > AFAIK the life span of Shimano Dura Ace cassetted with Ti sprockets is > dramatically shorter than steel Ultegra level cassettes. I did not know this. Steel can be treated in many ways to change it's characteristics of hardness, durability, etc. I know the various "HG" designatiions perform differently. Maybe DA is meant to wear out? The Actiontec stuff looks like the intended market is MTB. If so, it would have to be abrasion resistant. dougP --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
