For Sale: *BRAND NEW* Condor Pista

I emailed Condor about my confusion and this was their response...

Sorry for the delay. A 52cm is the correct size for you in that frame.
You might be looking up information on a different type of bicycle
frame to get the numbers you've found, without sounding a bit to
geeky, there is sloping and non-sloping. Non-sloping is a traditional
frame and the cross bar is horizontal with the ground and is general
4cm smaller than modern frames. So yes, you are correct if you were
getting a traditional geometry frame you would need a 58cm.
