Yes, the actual toptube length on the short is 20" centre to centre - super short but perfect for me

. Not sure how much bigger the 'long' is. I use
mine for my short commute, d/h and everything in between and love it to bits. It's no lightweight but pedals well and gets me up most stuff with 1x9 - there's a bit of noticeable bob in the very lowest gears but I guess you'd get that whatever the suspension design.
