The LBS should help you out......did they not fit you for the frame in the first place? They should be ashamed of themselves if they did!
I think I'm partially at fault. Pretty sure I went in asking for a 54. My first steel road bike a couple years back was a 54 and I came to the conclusion of getting that size based off of a height chart, but this was back when I knew nothing of cycling. Still learning, and now that I'm riding more I'm starting to understand what I need.
the smallest three sl3s were like all the same reach. Only thing that changed across the 49 52 and 54 was stack.
Do yourself a favour and get a proper fitting done, it'll take out a lot of guess work and save you money down the road..
Otherwise, the bike looks nice..
Yeah, I'm just going to go ahead and schedule a Body Geometry fit this week. Too bad the LBS I bought it from doesn't do them.
