So I'm in the process of upgrading my 1990 Miyata 1400A to 8-speed Dura Ace 74xx. The wheels that are currently on the bike are a set of Matrix ISO C-II rims laced to the original Shimano 105 hubs. I acquired the derailleurs within the last month and recently received the DA 8-speed cassette. Well what happens when I go to put the new cassette on? IT DOESN'T FIT, DUH! Ah how could I not have seen it coming? For anyone who doesn't follow, the older 105 hub was only made to accept up to 7-speed cassettes, which until today had not clicked in my brain. Oh, and on top of this, I just had the wheels re-dished/trued!
So, as I see it, I'm left with a few options:
-Rebuild the rear wheel with a new hub that will accept 8-speed cassettes (cost of the hub aside, can anyone give an estimate of how much this would cost?)
-Upgrade to a new wheelset - I am pretty happy with the current wheelset, but wouldn't mind something a little nicer, especially given that the rear hub won't accept anything higher than 7-speed. (can anyone shed more light on the wheelset, pros/cons etc).
-If I do upgrade the wheelset, what would be the best upgrade? I was looking at Mavic Open Pro's laced to either modern Ultegra or Dura Ace hubs. How much of a difference would this upgrade make as far as weight and performance goes? Is it worth it?
ARGGH I'm so bummed out and frustrated. I was looking forward to going on a nice ride tomorrow.
Any other suggestions would be greatly appreciated!
