Hey guys,

Background info: I am 6'2" 165-175lbs with a 32" inseam (not sure if that matters for bike fitting?) I regularly mountain bike and used to compete in DH racing. I want to get into road biking and have no clue how sizing works. Some bikes i see use just a regular S,M,L,XL and some use some form of cm or mm for sizing. I can't afford a new bike so I'm looking for a used road or aero bike. (I'm leaning towards aero bikes cause they look so cool) based on the above info on height does anyone know what size bike i should be looking for?

Thanks!!!

I'd recommend you buy an inexpensive for you, bike from a bike shop and go with what the manufacturers sizing and bike shop recommendation is. While sizing of bikes is somewhat is somewhat the same from one to another mfr, the different type bikes and geometries will feel different so a XL in one may be a L or 60 cm or 58 cm in another.

Don't buy a bike for it's cool looks. Buy it because it's appropriate for the type riding you are going to do. Basing part of your decision on cool looking colors is okay if it comes down to two different road bikes or two different gravel bikes and etc.

Nope. Go to https://www.competitivecyclist.com/S...ke.jsp#results
Take your measurements and put them in. For you, I think the competitive fit. That'll give you a range of measurements. Compare those to your candidate bike. You can pretty much ignore seat tube length, go more by top tube length.

You'll have to research frame measurements for the used bikes you like the look of, should be available online, google.
