I just got back from a after work climbing ride. I've been using a bike setup with a Dura Ace/Ultegra 10s Triple setup. Right now it's geared 53/39/30 with a 12-30 cassette. I was glad to have that final gear when I hit a 19% grade today.

I've also got a Campy Racing Triple setup as well as several compact doubles. I honestly don't find a properly setup triple FD to be a problem.

On top of the triple/compact decision you might want to consider your actual position on the bike. I find that I like bars a little higher than normal on my climbing bike as well as a saddle that's flat with lots of room to move around on.

I have both set-ups. On my old Bob Jackson I have a 10s STI 105 triple shifter set with a 12-30 cassette and a 48-36-24 triple. Shifts fine. On my Anderson, I wanted STI hydro, so that's a 2x11. 44-33 front, and for D2R2 it's got a 11-40 cassette (R8000 Ultegra RD with a Wolftooth DM link). Lowest and highest gears similar, larger jumps on the 2x11 cassette. Normally that bike wears a 12-34 cassette, fine for Martha's Vineyard's paltry hills.

My Litespeed Unicoi drop bar conversion usually has the 11-40 and DM link, 11s Shimano hydro shifters just like the Anderson, but a 42-28 front gives a 18.4 inch low gear, because that bike gets both single track and pavement mixed duty. It's set up to get all 11 cogs on the 42T chainring.

Hmmmmm. Right tool for the job, as my beloved grandpa used to say.

For local rides, which are certainly hilly but not, um, mountainous, a standard 53-52/39-42 with a 12-28 works just fine. So does a compact. Hardly ever have to shift into the small ring.

For more steeply rides, a compact with 12-28 does the trick, Skyline Drive, Thunder Ridge, long relatively steep pitches, the 34-28 combo does the trick with a bailout just in case.

For truly difficult climbs, like in Southern Wisconsin or Eroica, pull out the jams: either a 50-28 ring combo with a 13/28 freewheel, or a 38-36-24 triple with a 13-32/34 cog set.

Oh, and I'm 68, so I understand about the whole age thing.

I've had three surgeries, on my left knee and two on my right. I've had back surgery as well. I pay close attention to my position and what my knees are telling me.

I have one bike with Campy 46 - 36 which works well enough for my fendered putter around bike. The 50-34 always had me at one end of the cassette or the other.

If I find myself needing a wide range I'd go triple.

Don't know how the 48-38-28 fell out of fashion. Great compromise for everything except serious racing.

The difference between a 50 and 46 big ring is no more than 1 sprocket on the cassette. The difference between a 36 and 34 is even less.

The new 48/32 from Campy works great with the 11-34 12 speed cassette. The low is the same as an old 28/29 on a triple. The 48/11 provides plenty of top gear. If you don't need the 11-12, don't use them. An old 10 speed 13-29 cassette wouldn't have them.

FWIW, I used a 53/39/28 triple with a 12-25 for 5 years, riding in the Colorado mountains. I finally switched to a compact crank when 11 speed came out.

My triple works great

I switched my Serotta CIII with a DA 39-53 double 8+ years ago to 38-50 TA rings and have never regretted it.

My Chorus equipped Rambouillet has a compact crank with 36-50 rings and it works great too. However, I've known for some time that I could really benefit from a triple as I'm now 65.

In January I picked-up a NOS CIII (same size and color as my original) on this forum that had a 6503 Ultegra triple with 30-42-52 rings, 12-27 in the rear. Because of my experience with 38 and 50 rings, I immediately switched to a 26-38-48 TA configuration (thanks to Peter White Cycles). This new set-up works perfectly and the shifting is as good or better than any that I have ever used. I may switch to a 12-29 cassette before I take CIII No. 2 into the mountains.
