I've been riding a 2013 trek 2.1 madone(alum frame carbon fork 105GS) this season. I love the bike it fits and rides well, only thing I've graded was the ****ty squishy affinity 1 seat it came with to a paradim RL. I really have no desire to go for "lighter"upgrades being it still a alum frame coming it at 20lbs stock, and I'm better selling it when the time comes and upgrading to a whole new carbon, just wondering comfort wise would a carbon seat stem be much more noticeable then the stock alumni it came with? Or not worth the $$? Just wondering if it make a difference 2hrs+ on the road when you start to feel the bumps a little
More.

Cheers thx
