Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Show us your triple drivetrain (AKA The Triple Support Group)

While the triple haters sit at home playing this: http://www.tourdefrance-thegame.com/?xtor=AD-1

Triple users are out completing century rides that include 5000 ft of climbing.

Have a triple on your road bike? Show it here;

I run a 50, 39 & 26t triple with a 11-23t cassette. Using the large and middle chainring, I have tight 7 to 9% changes in cadence from 17 to 36 mph. If I need to climb a long, steep hill: I have the gears to do it.

My 2007 Pedal Force RS with full Ultegra 6703. My best time up Mt. Rose is on the triple and not my other bikes with compacts. I used this bike on this years Everest Challenge as well. 52/39/30 and either 11-26 or 11-28.

I'd like to get the newer FSA carbon triple like on the Red Performance brand bike above but it's not available in the USA as a standalone.

Because people that own triples RIDE triples. They don't don't photo shoot as much as double riders who think the more pictures you have, the faster you can go.

2011 Trek 2.1 at Redbox on Angeles Crest;

Mostly stock, swapped wheels out for Mavic Open Pro 32h laced to Ultegra hubs. I just bought an Ultegra 6700 Triple drivetrain, and debating to put it on the Trek or build up a CAAD10 or some other frame.

Funny story, I actually didn't realize it was a triple when I bought it from my LBS... was kinda bummed and considered exchanging it for the same model with a compact. I'm glad I kept it, even if I'll eventually not use the granny gear, its great to have that gear as a backup for those extra long rides/hills! I'm usually in the middle ring anyway, and find the ratios perfect for the type of riding I'm usually doing.

I have some nice pictures of my travel bike (above). I just picked that one because of the snow and the view to the valley ~1000 meters below. That's Madrid off in the distance..

I was going to take pictures of my triple in front of the garage but decided to do a double metric century instead.

If you used a 50/34 and an 11-28, you'd have the same high end, almost the same low end (just at 2 gear inches difference) and the progression between gears would be just about as tight.

What you wouldn't have is the number of redundant gears.

http://www.gear-calculator.com/# does a nice job of showing this graphically.

Overlapping gear ranges are essential to smooth progress up and down the 18 to 30 mph speed range.

Would you want a bike without any overlap in gearing?

Oh, and there are better gear ratio tools out there too.

I also can install a ten speed 12-30 cassette for truly steep terrain, like this: http://www.mapmyride.com/routes/view/57295864

If you need a gear below 34/28, then th etriple makes sense. so if you wan the ability to use the 12-30 with a 26 front ring, the triple's almost a neccessity.

However, the 50/39/26 with 11-23 setup is easy to virtually duplicate the useable gears with 50/34 11-28.

That's gives you a smooth progression, with one cross over shift at 50/19 to 34/14. You are going to have to make a double shift there, but I'd gladly take that in exchange for less weight, less complexity, better front shifting.

And as for a smooth progression from 18-30mph, at 90rpm on the 11-28 setup that is all on the big ring, and the largest jump is slightly over 1mph.

With 10 and 11 speed cassettes, and compact cranks, Triples just aren't necessary to get good spacing. They still are good for very low gears.

You really are stuck on the "a double is better than a triple" concept that the industry pushes to reduce SKU's. BTW, your math is flawed. Your spelling needs help, too.

An 11-28 has greater than 1 mph jump for every cog on a 50t chainring. At 90 rpm, the progression is 12.9, 15.1, 17.2, 19.0, 21.3, 24.1, 25.8, 27.8, 30.1, and 32.9mph.

The significant jumps you're showing don't consider that you've got 2 front chain rings. You're not going to be in the 50/28, or the 50/24.

What I like about the gearing website I linked to is that you can see the progression of the gears on both rings, the cross over points, and the duplicate gears.

This is useful for side-by-side comparisons;



This is better than the website you are using: http://home.earthlink.net/~mike.sherman/shift.html

The screen shot from the website I'm using gives you a good graphic that shows the range and the spacing are pretty comparable:
