Does anyone know which manufactureres will be including Force on their road/tri bikes next year? I haven’t really heard much about the release plans yet, other than “late summer.”
Tri bikes? Probably zero. AFAIK, no plans by SRAM to produce a thumbshifter this season. That will pretty much take it out of consideration for tri bike spec.
.
I’m thinking road only, unless they are also releasing bar-end shifters. As for manufacturers, who knows? Trek and Cannondale tend to unveil thir range a little earlier than others, but I’m guessing the public won’t really know who’s going to be speccing this stuff until Interbike?
I road a Cannondale System 6 with an OEM Force group on it last weekend. It did have a Cannondale SI crank though.

Not to hijack… but are any of the Tour teams using the SRAM gruppo this year? I know it made an appearace at the TdC
Good point - I forgot that they hadn’t shown a bar-end shifter yet. Is there any possibility that a Dura-Ace bar-end will be compatible?
a 57cm Orbea Opal with SRAM will be arriving at my LBS any day now.
"Is there any possibility that a Dura-Ace bar-end will be compatible? "
Nope - unless someone makes an aftermarket cable pull adapter.

Should be lots, Specialized, Orbea, Cannondale, as well as smaller brands that use build kit options. TT shifiting options still seem to be very secret. You can’t simply use a Dura Ace shifter, as the derailleurs are not compatible. I suspect that the minds of SRAM aren’t going to settle for a simple lever. My PD time would go into developing a remote shifter that allowed multiple shifting locations, but I don’t do drivetrains.
Should be exciting to see other options for 2007, albeit a gamble for those companies.

what did you think? Was the shifting intuitive?
My LBS seems to think that campy cassettes/wheels will work with the SRAM system. Which means the campy bar ends might work as well.

Funny you should mention that: http://jtekengineering.com/shiftmate_straight.htm
Of course, you could run it in friction and it would probably work O.K. as well.
Yup. That’s who I was thinking of, actually. But they will have to make yet another model - the SRAM road derailleur has a different actuation ratio than the Mtn. unit…
.
When the shop guy explained how they worked I was skeptical. As an STI user it seemed all wrong. It turned out to be completely intuitive after 3-4 shifts. After 5 minutes on the bike, I would be willing to road race on it. The levers swing in an arc around the bar so they don’t get further from the bar as you push it. Makes for a really nice feel.
I’m too cheap to upgrade, but I’ll seriously consider next time I replace my road bike.

“My LBS seems to think that campy cassettes/wheels will work with the SRAM system. Which means the campy bar ends might work as well.”
No offense, but that’s a ridiculous assumption. It’s a total apples and oranges situation. Cog spacing has absolutely nothing to do with the actuation rate of the derailleur, which is what determines shifter/der. compatibility (OK, not exactly nothing to do with, but… well, read on…)
The geometry of a derailleur determines how much cable pull is necessary to make it move a certain distance, and the shift lever must pull the right amount of cable per shift to index with that movement. If your derailleur needs, for example, 2mm of cable pull to make a shift of a given distance, than if your shift lever is designed to pull 1.5 mm, you are out of luck.
The cassette spacing determines the distance a derailleur cage must move to make a shift, but the derailleur geometry determines the cable actuation rate, and this can vary dramatically for any particular amount of cage movement, said variance determined solely by the derailleur design, and independant of the cassette spacing.

The Price on the Sram Rival is lower than 105 from what I’ve seen on websites and a lower weight than Ultegra. I think it’s going to be a new popular option to budget shoppers who were in that 105/Veloce/Ultegra/Chorus conundrum.
No offense? Bullshit. you meant to insult me. That’s why you posted it twice!
Let me clarify a few things for you. FIRST, all derailleurs are parallelograms - which means they are ALL EQUAL! Duh, that’s what PARALLELOGRAM means. Jeez, it’s so SIMPLE, how can you not get it!
You are, of course, correct. I suppose the SRAM with Campy could be addressed the little wheel thing, but what’s the point? You may as well go with Campy in the rear. It would be very nice if the SRAM cassettes and Campy cassettes are compatible. Gives me an option for my next road bike.
Wierd… the double-post is a strange glitch!
I promise - I only posted once :0)
As regards cassette compatibility - my understanding is the SRAM cassette will use the Shimano spline and spacing standard, so will be cross-compatible with Shimano, but not Campy.

My LBS has a bunch of Orbea’s that have SRAM as OEM on them in the shop already.
