Does anyone have any experience/owned a 2009/10 Corratec Air Tech? I am looking at purchasing one online for a very good price but don't have any bike shops that stock it near where i live so don't have chance to try one out for size first.

I am aware from comments online (such as the one on bike radar http://www.bikeradar.com/gear/catego...utant-09-34462) that they are on the small side for their sizing.

I know it is down to personel preference and everyone is different but as a general comparison I am 5' 11" and currently ride a Kona Kula 18" which is a perfect fit with a short flat stem and low risers. The sizing appears to be in metric: 49cm and 54cm - not sure what sizes these are in old money!

Thanks in advance, Andrew
