It may be nice to have since it only has about 300 miles on it.
    Nice!

    That gear calculator is cool.

    I have my gripes about compact doubles, but fiddling around with it, I think I'd be happy with this odd combination: 49/36 with a 33/11 (33, 29, 26, 23, 20, 18, 16, 14, 13, 12, 11)

    Good luck finding that combo though.

    I bought the compact from Wiggle.com in GB. Best price I could find. They estimate delivery in 8 days but don't guaranty it because of customs. I've bought from them before and they seem pretty reputable. Anybody have any other decent sources?

    My chainrings of choice currently are 52-36. Called "mid-compact" it was on a recent Specialized Tarmac I bought. With a 27 or 28 tooth cog in the back, the 36 small ring suffices for the hills I encounter. With a 34 small ring, I find it hard to find the sweet spot of cruising on the flats without cross-chaining.

    I used to think triple was the only way to go, set up one bike with compact double and quickly changed my mind. Now have four bikes with 50/34 cranks and various cassettes from 12/30 to 11/32.

    Yeah I was lucky to be using that Sugino 110 bc retro styled crank with a FW because I could get Sugino MTB rings for it. Campagnaglo made some thinner rings for the 110 bc cranks but most of them have one offset bolt hole and won't fit anything else. I did find some old Campy NOS rings for it, in what I wanted, that are 110 all around and will just save them it for whatever.

    Finding non standard rings for the other brands of compacts is something I haven't looked into but I imagine lots of people have crosschain issues with the 50/34 setup on those......They really should make 'em.

    I have not quite warmed up to the standard compact crank (50, 34) yet. Last year's WI ride was my first extended trip on a compact and I didn't like how frequently I changed the front gears. Probably because I work out exclusively on a single-speed, --I look for a single chainring that covers 90% of my needs. That used to be the 39 or 42 front chainring. Front gear changes always seem disruptive to me compared to how smoothly I can dial in the rear cluster.

    I am building a 42, 26 "sub compact" to see if that feels "perfect" to me (42 for everything, unless there's a killer steep hill where I need to spin up the steep face). Not tested yet, so I can't yet say I love it.

    Never ridden a compact or a triple, not much help.

    Campy makes a 12-30 cassette. Paired with a 39/53, I have used it twice on the Assault of the Carolinas, which has a 7 mile climb closer to the end varying between 7% - 25% gradient.

The recommended gear inches for hilly riding seem to point to a compact crank but before I spend the money I wanted to see how others felt.
    As you say, the trick to life is to keep moving. I'd say, go one step lower and see how it works. If after you acclimate to the new gears you want to spin faster and go lower, do it. It doesn't cost a huge $$, and it's a lot more fun than having injured knees or having to walk up hills. Do what keeps you moving comfortably.

    As noted I have a 12/29 and was told that on a Campy 11 speed a 29 cog is the largest you can install without changing the rear derralluer. I'm not sure the compact is going to suit me since my legs are getting stronger and I find that hills are getting easier. I have noted that I don't use the 53 chainring much and perhaps the 50 chainring will get more use. I might stay in it more. Will see.

    On my 650B I've been using a 26/44 TA Cyclotourist with an 11/28 rear. I finally am tired of extra careful front shifting, so I just installed a 53/40/30 Campy Record Triple. It shifts better, and it will be great when I get my Ergolevers. There's probably a Shiftmate in my future, too.

    I like to be able to spin when I want to and at the speed I want. The compact double was not flexible enough for me.

    Received my compact yesterday and installed it this morning. Took a link out of the chain and lowered the front derailleur. Tightened the cable. Seems to shift okay on the stand. Piece of cake. Anything else I'm missing? Looking forward to the hills on tomorrows ride.
