Thinking about going triple on new bike Record or Chorus.Nine speed is cheaper.What is the advantage of ten speed group?

I rode Campy eight speed for 7 years. I switched to nine speed when I moved to South Carolina and started riding in mountains. The extra gear helps.

In the local, heavy rolling hills, area even nine speeds are useless. Around Columbia I run a 12-21 and never use the 21. In a ten speed I'd run a 12-23 and then I'd never use the 21 and 23.

However .... if I did more mountain riding I might switch. In the mountains I run a 13-26. It'd be nice to have one more gear inside there.
Have you calculated the gear ratios?DCW

I'll assume you have, given your decision to go triple.

If you have not, plug in data for both triple and double chainrings and for a variety of cassettes, both 9- and 10-speed, on Sheldon Brown's site:

You may find that there is no great reason to go triple. For a series of Alpine climbs next summer, I decided to keep my double and go 13-29 (with a med cage rear der.) rather than switch to a triple crankset with my 12-25. I sacrifice only a couple of gear inches at low and high ends.

I addressed the 9/10 issue about two years ago with my new bike. My first notion was that 10 speeds were overkill. I also wondered about spending more $$ on new technology. Well, I went Chorus 10-speed on the advice of Gary Hobbs and haven't regretted it a minute. The extra $$ were relatively few in the scheme of things. The 10-speed gives me two gears I wouldn't have had. Especially in the 14-19 range, I like the one-tooth choices -- they save a lot of chainring shifts.

Good luck.

I think the Campy 10-speed groups are only available with doubles. With a triple, I think you have to opt for the 9-speed groups. I opted for the 10-speed Chorus group with a 13-29 cassette. It's got most of the climbing ability of a triple with less weight and parts, but your gears are a little more spread out.
regrets? i'm facing the same decision. nmJs Haiku Shop

regrets?tarwheel

The only regret I have with the 13-29 cassette is losing that 12 gear on long downhills. I am considering buying another rear wheel with a 12-25 cassette for general use and keeping the 13-29 wheel for riding in the mountains. I rarely, rarely ever need the 29 gear, but it sure is nice to have when you need it.

The big advantage of the triple is being able to run a very tight gear cluster, like a 12-21 or 12-23, while still having some good climbing gears. I haven't used a triple (except my mtn bike), but I have heard they can be much more tempermental keeping the derailleurs adjusted. And most people rarely ever use the smallest ring.

my bianchi is a triple, and i have used the small ring when in mountains, or large hills after a good number of miles in for the day. however, it's more than overkill 'round home. i was considering the same: second rear wheel OR another cassette and the tools to change 'em out.

my question was more to the chorus decision. had you considered daytona, ridden it, etc.? i'm thinking chorus also, but the difference in build kits from gvh is several hundred clams.

thanks.

You know, I really didn't consider Daytona but I probably should have. From what I hear it is functionally very similar, but a little heavier and less polished. Come to think of it, though, I think the Daytona was only available in 9 speeds when I was shopping. If I was looking now, I would give very serious consideration to Daytona. It may be the best bargain right now in groups.
why not just buy a new cassette?nm

instead of wheel, cassette, tire, tube, etc.

At least in my case. Can't speak for Haiku. I was just thinking it would be nice to just swap out that rear wheel when I was heading up to the mountains for a weekend rather than fool with changing a cassette. I'm not the most mechanically inclined person either.
