I agree with charlesc... 1 degree makes a lot of differences in the way the rider feels the frame (well some people cant feel a difference between a colnago master and a 50 bucks wallmart bike anyways). somehow as stepper the angle the faster the feel because u are more over the pedals but the bike gets more hmm... i dont want to use the word stiff but well probably u guys got the idea... a 73 degrees bikes is very soft, the chainstays are longer also those 2things makes the frame very soft... in a 75 degrees frame for sure u'll feel all the pots and holes on the road, not compfortable but the bike for sure is ver very fast... well thats my 1+.. done listen to me ok im drunk!
