Going Backwards

I'm growing tired of the seemingly constant trimming needed during a ride to keep my 10 speed system running quiet. What would it take to change to 9 speed?

The chain and cassette are easy. Would the current chain rings work?

My setup is:
FSA SL-K LIGHT triple crankset
Ultegra Front Derailleur
XTR Rear Derailleur
Dura Ace brifters

had the same with the shimano stuff, now changed the whole setup to SRAM X9, with the 1:1 technology.
Perfectly direct and smooth shifting. No noice at all.
With the 1:1 technology there is more cable movement between each gear.

But this system won't work with race brifters.

you can use the 10 speed cranksets and chainrings without any problems in a 9 speed setup, same for the front and rear derailleur.
But you'll need 9 speed brifters !

We have the nice carbon levered 6703 Ultegra 10spd brifters which work perfectly and do not require extraneous trimming. We do use a XTR 9spd rear derailleur that has the same throw ratio as the official 10spd ones, so no problem there.

Curious how you are using Dura Ace brifters as part of a 10spd / triple setup, since there are no DA designed for that config? Are you using 9spd DA triple brifters or DA brifters for a 10spd double ring setup? Plus what other components are you using that are not officially for 10spd?

There was a 7803 Dura Ace 10-speed triple group. It's only the 7900 and 9000 series' when no DA triple was offered.

My brifters are labeled "Dura Ace Flight Deck Triple." I don't see a number anywhere. They are the older style where the cable goes out the side rather than goes under the handlebar tape.

I've talked to several other riders with 10 speed systems who have the same problems as I do.

Peel back the rubber hood, the number is molded into the plastic.

My 9 sp Ultegra brifter and FD shifts 10 speed rings perfectly. It's fussy, but I can adjust it so it doesn't need a trim with any ring/cog combination that I use. I don't use the smallest cog with the middle ring, the largest two cogs with the big ring, nor the smallest 4 cogs with the inner ring. I notice that when my middle ring gets worn, shifting suffers and the adjustment gets trickier. New ring fixes that.

Bar end shifter may work.

My bad. As Chris pointed out the 7803 DA is 10spd. I just didn't realize that old style (cable out the side) was made for 10spd.

I've had very good results using the 67xx series Ultegra components + the XTR M972 RD. No shifting problems or fiddling with the trim once it is set, it works. Photos of the build last year were posted here: http://www.bikeforums.net/showthread...ee-Tetra-build
