I'm not gonna wade through the whole thread 'til the weekend, but...
I ran road triple for a while and it was nice, but I only dropped into the granny on a few occasions. I've the 42/53 now and feel like a wuss for buying a 39, but I'm old.
In the back, I'm running a 28 big cog on my clincher wheelset too. Still tough it out with a 13-24 on the tubular set. I don't know how I ever managed with a 13-21 back in the day.
