I have been looking to get my first road/tri bike.. I likely for cost purpose and comfort going to go with a Road bike and add the aero bars and maybe the saddle post mod for Tri's.. My question is that on a road bike I would get a 56cm... I am a 5'10... several LBS and fellow training partners are telling me I should drop down to 54cm if I am going to do the mods... several others are saying STAY with the 56cm and just get the "mini" areo's and I will be fine.... so it is half a dozen one way or the other. Just for clarification.. If I was to buy a road bike and hadn't mention tri's.. I size out to a 56cm...
What I would like to know is will the 2 cm make that much difference either way, if so can someone explain this to me.. Both sizes feel fine riding, I am a newbie, so i can't tell a difference.. Is the difference so minimal that it really doesn't matter? Would I be just as comfy on the 54cm..? Or is it preferable to get the 56cm since without the tri's modifications that is what I would size out at.
Do any of you have any suggestions or explanations for me..
Thanks from a newbie... btw: I have my first tri next month.. I will be riding my 29er mountain bike it looks like... unless I get a roadie in the next week or 2..
