I'm about 5.9 175lbs and my inseem is about 33. I went to the LBS a few times talked to 3 different sales people and of course got three different answers.

I'm looking at either a trek 1.5 or 2.1.

1. said the 56 frame looked good but he didn't like how far I was reaching over he recommended trying a smaller stem.

2. Another person said i should ride a 58 but I did say i was 6 ft tall my mistake.

3. The last guy said he could fit me on a 56 but from what he could tell i looked more comfortable on a 54.

My real question is this if i am between a 54 and a 56 are there any pros and cons for changing the stem? Will it change how the bike handles?
