9-spd Dura Ace compatibility(7 posts)

9-spd Dura Ace compatibilitydsc
Oct 1, 2001 7:08 PM
Hi- just bought a '99 Lemond Zurich from a fellow who, among other things, outfitted the bike w/ the full Dura Ace component group. It's 9 speed, so I know that the group is at least from 1997, but pre-Flight Deck, so could be '98 or (possibly?) early '99.
My question: Any known compatibility problems/issues w/ the currently available 9 speed D/A parts when mixed in w/ the vintage on my bike? No problems at present, but I would like to upgrade to a 12-27 cogset in the near future.
Thanks in advance for any information.

All 9 speed Dura Ace and Ultegra should work. Many people I know use Ultegra because it is a little less expensive and supposedly lasts longer than Dura Ace. It might only be hearsay, but they say the titanium cogs wear out too fast relative to the price. If you are a weight weenie though, then stay with Dura Ace.

All D/A nine speed parts are interchangable. The only part that is different with flight deck is the STI shifters. The Flight Deck STI's have buttons built in to use the computer. As the above poster said, all 9 speed Shimano parts are interchangable

Thanks for the info. guys. Anyone else have any experience w/ the Ti cogs wearing out faster? I've always avoided them on my MTB for that reason, and yes, I do plan on being in those gears a lot :)

Don't have experience with Ti sprockets, but I once read they wear less quickly if you replace your chain regularly.
But, Ti DA cogs are very expensive and if you are not a pro Ultegra will do the job very good as well.

I have DA9 components and DA 9sp cogs that don't shift well at all anymore. They shifted perfectly when they were new. I put them on last November. The chain hesitates to get up on the next cog and they make a sloppy shift in both directions. It causes me to have to overshift hoping to get the chain to land on a gear. The cogs can't have over 1200-1500 miles on them. My old DA 8sp stuff went almost 6 years before I had replace chain and cogs.

I know it's the cogs and not the derailuer adjustments, because I also have an Ultegra 9sp cassette, that when I put that on and touch nothing else, everything shifts like butter. The weight difference is not that great at all, heck, the Ultegra 9sp cassette is much lighter than my 8sp DA unit, and the Ultegra cassette is half the price. If you don't have new equipment handed to you on demand, there is something to be said for durability over weight, in my opinion of course. -NEIL

My LBS built up my 1998 5500 with Dura-Ace but with the HG 6500 Ultegra 12-27 cassette. It's worked great but when I replace the cassette and chain I'll go with the D-A 7700 12-27 with partial Ti cogs, it's only $75.
