Hi
The observant of you will know I just bought a Longitude (2017) F&F to build up. I ordered a medium. What has arrived was in a large box, I don’t know if it was the correct box. I had a bargain on the frame.
on the bb shell is stamped 8 L-480 opposite the frame no. The Genesis sizing for a large (centre BB to top) is 480mm or 19″. I measured my seat tube from mid bb shell to the top of the seat collar flush with the top of seat tube and its approx 480mm/ 19″.
I’m guessing then that I’ve been sent a Large. I just wanted to confirm this and that the convention is to measure to top of seat tube and not the top of the top tube where it meets the seat tube (Ie where you get the standover height) surely it would say this in the Genesis catalogue.
I’m 5’8″ on a good day and usually I ride a 17.5″ frame – my last genesis, a latitude is a 16.5″ and if anything thats a little too small.
Thing is, I don’t want to go build it and find out it’s too long/ high. I’d rather send it back, get the right size.
