    Question DA rear 10 spd w/ Ultegra FD?

    I'm going to upgrade my 8 spd Ultegra drivetrain.
    My current plan is either a 9 spd (Ultegra or DA?) or a 10 spd DA. My plan is to just get a cassette, chain, RD, and STI shifters. I upgraded the crankset last year to the '03 Octalink Ultegra crankset and FD. The rest of my bike is original Ultegra ('97).

    I want that 25 for my poor knee, and my current cassette and chain are getting close to their end. 10 speed seems like it will last me longer until my next upgrade, but it isn't free... Ultegra 9's are out there, but not that much less than DA 9's.

    I know that the crankset is cool with the Ultegra 9 speed, I like it, it is paid for, and it has a lot of miles left.

    Will it work with the DA 10 speed cassette and chain?

    You don't even need a new rear derailleur. Get the cassette, chain, and a new rear shifter. Install parts. Adjust. Ride bike.

    A counter-argument:

    Remember that 10-speed doesn't extend the range of your gearing, it fills in the gaps in the middle, most of which are caused by Shimano's stupid "everyone must ride a 53-39" default chainring selection. Also, 10-speed DA cassettes are REALLY freakin' expensive, and so are the chains. Shimano 9-speed cassettes are plentiful, and likely to remain so. They still make 7 speed cassettes, after all. They are also about 1/3 the price of the new DA 10 cassettes.

    True, Campy is just as guilty, plus they use a different BCD from the rest of the universe. With regard to "gaps in the middle", the smallest cog of a cassette hasn't changed since the introduction of the 11T cog in the late 80's or early 90's, and short-cage rear derailleurs are still limited to 28 - 30 teeth. The extra cogs have allowed tighter spacing on a cluster, but the extremes are the same.

    Going to a 50T or smaller big ring moves all of the gears on that ring down, and if carefully selected, can result in tighter overall gearing, with more combinations in the useful range. Non-racers don't really need 100+ inch gears, most of the time.

    now's your chance to go campy...

    Have you considered a campy 10 conversion? All it would require is much cheaper ergo levers, a much cheaper American Classic cassette, a Centaur or Veloce rear derailleur (additional cost, but still less than shimano) and a new chain. All the parts can be had for about $355 - les than the price of DA 10 shift/brake levers. Personally, I'd add a new FD for $35.

    Nope. Just fat, slow, and I don't care. I just like bikes. I like to ride 'em, work on 'em, talk about 'em, you name it, I like it.
