Age... Compact or triple?
Knees are getting older... The time has come.
Triple or compact? Change crank arm length? Just curious what everyone else has done with success. At present, I run 172.5 52/36 with 13/29 or 12/25 Campy 10.

Triples are no longer made by Campy and their shifters no longer support a triple FD. Consider that latest Chorus 12 with a 48/32 and 11-34 cassette. I switched both of my bikes recently and it works great. Having a low gear of 32/34 is lower than the triples I used in the past.
I've had a triple with a 28/29 low, but the new compact is just a bit lower.

Triples can be very fussy with shifting. I think they are a thing of the past now. With 11-speed, long cage RD, you can get just about all the gears that a triple can. And if you come to the worlds steepest climb then just walk

My only gripe was I had a 3rd bottle cage and the smallest ring would interfere with water bottles

I've never had a problem shifting triples from Campy or Shimano. The only compact I had was 50-34 Ritchey cranks with 9 speed Veloce/Chorus/Record mix with 12-26 9 speed Campy cassette and it worked fine too. I also enjoyed a 48-38-28 TA Zephyr with 10 speed Chorus and 13-29 cogs. I still have the 24 tooth cog in the original package because I didn't need to go that low. Most of my bikes with triples had longish chainstays and they probably helped by reducing chain angles.
My last remaining road bike is my Riv. Rambouillet with 6503 Ultegra triple 52-42-30 and 12-27 cassette. I spend a lot of time spinning along in the 42 ring and the middle of the cassette saving the 52 for downhills and tailwinds and the 30 for steeper hills than I can manage in the 42. With 50-34 and 11-26 9 speed I found some gaps and/or slightly awkward shift points but I wasn't racing so that didn't really matter. Maybe a compact with 11 or 12 cogs would eliminate those gaps but I haven't tried any of that new-fangled stuff.

I put a triple on my wife's bike (Campy 10). It has the same range as her previous 2x did, but with much smaller jumps (obviously). She is now more likely to have the right gear which has enabled her to more consistently hold a pace.
I love triples, unfortunately my bum knee can't tolerate the increased Q factor.

What's your chainstay length? 410 would be bit too much angle, longer chainstay will help that issue.
Of course what riding type, kind of roads you ride etc all affect the decision It's not just the crankset of course if going down that road. Compact double will probably slam on their without other investments.

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. Last edited by Dave; 08-17-2019 at 04:06 PM.
