Hi Mike, Glad to share my experience as I had a bit of a difficult time figuring this out myself.
I have White Industries VBC Road cranks. Originally I had the mountain/ENO cranks, but the limiting factor is chainring clearance, not crank clearance, so if you haven't bought any yet do yourself a favour and get the lower Q-factor road cranks. I'm running a 44/26. Originally it was 44/30 which works fine, but I dropped to a smaller inner ring before touring in the mountains. Rear cassette is a 10-speed 11-36. I find this is just about perfect. I never use the 44x11, even flying down paved mountain descents. 44x12 gets a tiny bit of use. Maybe a couple of times after really long hard days I wished for just a tiny bit lower of a gear than 26x36, but again, that's after 100 miles a few days in a row. I'm using a Phil Wood BB. 119mm. I bought an offset BB but then pulled the spindle over so it was centered. Just did that because at the time it was hard to find a symmetrical 119. I think I could maybe go 1 or 2mm shorter, but I doubt it'd be a good idea. Might need to offset the spindle for proper chainring clearance. I suggest 119mm. You can see the evidence of chain-suck on the chain stay. It was like that when I bought the frame used, but I've dropped the chain in there twice myself. Common Atlantis problem apparently, though it hasn't happened to me in about a year of daily riding. Maybe it's a shifting technique, not sure. You'll also notice I have a Sugino inner ring - picked it up from Riv a while back. $20 bucks. White VBC can use ANY 5-bolt inner ring FYI. Nice way to experiment with sizes and save money. <https://lh3.googleusercontent.com/-eSll7iRI5Kk/VkSw-fgzNII/AAAAAAAANgU/x_UhRg9csCo/s1600/White.jpg> On Wednesday, November 11, 2015 at 5:31:12 PM UTC-6, Bill Lindsay wrote: > > What ring sizes will you be using? > > On Wednesday, November 11, 2015 at 3:11:04 PM UTC-8, mike gasparino wrote: >> >> Hi guys, >> building up a 2x10 atlantis and looking for recommendations for a double >> crankset.
