i just picked up a 2012 jamis coda elite (21") earlier today. before i left my LBS i had them change out the stock pedals for some odyssey twisted pedals (in clear), added some full fenders and two water bottle holders. soon as i got back home i put my serfas RX seat on the bike. i put about 6 miles on the bike so far, i have some more riding and tiny adjustments to make (seat height and position, handle bar height, etc). i plan on going for a pretty long ride around NYC saturday to put the bike through it's paces, probably 30+ miles. i'll report back with a little review. in the 6 miles i rode today so far, i really like this bike.
here is the bike before i left the shop today:
