I used to own a Berlingo - bikes fitted in no probs at all - my Giant was a Large and the seatpost was almost a foot in the air -

Where are you based? I have the first model of the Minoura Vergo - doesn't look as 'nice' as the one shown above as mine looks a bit more industrial - it works for 2 bikes with front wheels off and QRs...I believe 15mm and 20mm adapters work on it. It sits in my garage doing nothing...if it is of any use, I'm more than happy to sell it on...
The version I have is a double version of this -
- except it doesn't have the wee stabilising leg as the rack is twice the width and very stable...if this is any use to you let me know.
