Bub Marley Posted July 30, 2013 Share How often do you cycle and what sort of mileage do you do? If you are an avid cyclist which goes out everyday then it might be better to have a professional fit done. However if you're not that serious, then I don't think the difference is that important. Either size would work. The 58cm frame would probably mean you would need to lift your seat higher to get in a more aerodynamic position but you can modify both frames to get your seating correct.

quintonb Posted July 30, 2013 Share Well guys its says From 55cm to 59cm i can consider ...Thats a pretty wide range. You sure you input the correct info. Shouldnt give such a wide range.But honestly with that inseam I would say the 56 may just do the job. Who knew.

Then you will be 100% sure its the right size for you, and any bike you buy in the future can be referenced off that fitment. Link to comment Share on other sites More sharing options...

Helpmytrap Posted July 30, 2013 Share Well that's what I thought ( current. Frame is a Raleigh Rc ) but I don't think it's such a good fit . My inseam is 780mm so I'm not sure i think a 60cm ? Do u perhaps know ?Are you sure that it is 780mm? I'm 1.73m with an inseam of 840mm, I can't see how you are 16cm taller with 6cm shorter legs.Let us know what the LBS recommend.

shaper Posted July 30, 2013 Share Nice looking calculator.Will help a little better with regard to reach and inseam measurements, will be a little more accurate, but not as good as a proper bike fit Link to comment Share on other sites More sharing options...
