Will the Compact Crank Eventually Bury the Road Triple??

This is an interesting subject to me, as I may be re-doing the drivetrain on my Lemond road bike soon. I guess I'm just not seeing the point of road triples (i.e. 50-39-30, or whatever's clever lately).

Seems like a compact crank gets you almost the same gears, with less weight and complexity, and a better Q-factor. I still like triples, but it seems like if you're gonna get one, it should be a mountain triple (for da 'really low' low gears).

Or am I missing something that's really awesome about road triples? :confused:

I am with you on this, I would go with a compact (and a few flavors of cassette) before a triple, at least until someone comes up with a road bike worthy CVT. Though I have to admit it is, at least in part, a historical prejudice for me; 3 chain rings = touring/mountain bike. I was dumbfounded the first time I saw a Dura Ace triple crank set.

The weight factor doesn't bother me

The triple on my Lemond is good for early season rides when my legs don't need punished when riding the bigger hills in my area. It also is great for supported touring where you can ride fast if you want or take your time and slog up the hills.

As long as there are people loading up touring bikes with 50lbs of gear, road triples will not go away.
Huh... I thought ppl mainly used mtn triples for expedition touring? :confused5:

Kinda. The touring specific Shimano crankset is in the LX and XT lines. The rings are too big to use for any kind of mountain biking, so I would hesitate to call it a mtn triple.

Hmm... 48-36-26 rings, yes, but the same 104/64mm bolt circle as Shimano's mtn triples.

And, the little blurb below it does seem very mtn-bike-oriented:

Engineered for the way you ride. As Mountain bikes continue to become more diverse, obviously components must evolve. New Shimano Deore XT addresses the various needs of today's riders. New mechanism rear derailleur "SHIMANO SHADOW RD", specially designed for all mountain riding. Together with double-servo mechanism derailleurs now, you have the right choices for several off road riding styles. New XT disc brake, a new level of performance and controllability, features high power braking. "Engineered for the way you ride". With the same concept to as XTR, new DEORE XT is born.

I'd rather have a 53-39-30 with a 12-25 than a 50-34 with a 11-28.
That's true, a road triple will let you run a tighter cassette. Best argument I've heard for 'em yet. :thumbsup:

Heck, you could even go mtn triple and get an even tighter cassette, by that logic... but the Q-factor just ain't so good, and it sure is hard to find mtn triples in 172.5 for a decent price. :(

I have Campy Centaur on my bike with 53-42-30. The weight is a non issue at least for me. For most of us you could lose a few pounds off of the body. The shifting is fine. I see more people on my rides with compacts dropping chains. I just bought a bike with a compact 50-34 and I hate it. Too much shifting involved to stay in the right gear. When riding the triple, I can stay in the middle ring for the most part and just go up and down on the rear cassette. With a well adjusted triple there shouldn't be many problems. IMHO

I think compacts can take a 33t if need be. If that's not low enough, there are alternatives:
Hehe, 33 as the small ring... it's really beginning to look like a triple without the big ring...

That blurb is at the bottom of all XT compoents.

Meh. Call it what you want. I still consider a touring triple as being part of "road components."

Maybe mtn rings are easier to find at random bike shops in the middle of nowhere, hence the mtn BCD... *shrug*

I can't. It's just a mtn triple with slightly bigger rings put on, really.

That said, I'm starting to grok the road triple love a bit more now. Bruin's 'you can just stay in the middle ring most of the time' argument is a good point... to me, anyway. :cool:

More like a triple w/out the middle ring...
