Record Triple vs. Chorus w/13-29(6 posts)

Record Triple vs. Chorus w/13-29BenH
Jul 25, 2002 9:57 AM
I'm buying a groupo for riding in hill country. I've never ridden a triple on a road bike. I can get up the hills so far with my 12/26 but am considering going for the triple based on it just being easier to climb steep hills with lower gears (I now live in Seattle but have done a few Death Rides).

The negative so far is the extra cost for the triple. There is no Chorus 10spd Triple (I think they just sub the Record Triple parts in the Chorus Triple groups I've seen) and the hope that the 13-29 would give me enough extra gear and is so close to Record in quality and weight I'd get by with it just fine. Anyone out there care to comment ?

If you live in Seattle, tell me who's the best Mechanic around.

Hi Ben
I live in the SoCal area and ride lots n lots of hills, most in the 10-15% grade, but have tackeled some 22% grades. I am using the Chorus with the 13-29 and I love it. I can comfortably climb in the saddle @ 8-9 MPH , this is importiant to me as most of the climbs are 5-8 miles long. It gives me enough gear! Also its a bit lighter (1/8 Lb) then a record w/ a triple.

Spining is good!

You can use Chorus parts for all but the cankset and bottom bracket, right? The difference between a Record triple and a Chorus double is $220 vs. $120, plus $90 vs. $45 for the bottom bracket.

For the extra $150 you get more gears, both range and in between. If you compare a 12-25 with a triple and 13-29 with the double, the top ends are 118 vs. 108 gear inches, and low ends of 32 vs. 36 gear inches, respectively. At 90 rpms, the speed differences at high and low ends are 31.5 (triple) vs. 29 mph and 8.5 (triple) vs. 9.6 mph.

The triple will not shift quite as well in the front. The triple weighs just over 100 grams more. I would not use the triple for road racing. However, for most riding in big hills, the triple will be far more satisfying in the long run.

Disclaimer: I have bikes built up both ways, so I can choose which to ride for what I'm doing. But then, I do a wide variety of riding, ranging from 10 mile time trials, crits, road races, and ultra distances (master of none).

I like my 13-29, but...Stinky Hippie
Jul 25, 2002 1:05 PM thing I don't like is that the capacity of my Record long cage derailleur is pushed to such an extent that I get cog/pulley rub when I run the 29 tooth unless I run my wheel all the way back in the dropouts. This of course could be a non-issue depending on one's bike, but i would really like to be able to run my wheelbase at the shortest setting possible, and, uh....I can't .

Chorus triple is on its way. see rumor pageSnowBlind

Worse thing about 13/29 is the long Rear-DR cage, looks silly.
use long cage with triple, too nmDougSloan
