The bike in question, if I buy it, would be bought through the bike shop though they would order it online. I'm looking at a Koga Signature with that Pinion 18 speed gear box that is mounted where the front derailleur would be located ... between the pedals. The frame of course is tailored to accommodate the Pinion though the frames are only offered in two sizes.
