My 'best bike' and summertime daily ride, Rossin Record Pista in its different guises since I got it in 2008. Evolution or compulsive upgrading of parts for no reason at all? Not sure, probably both.
What's more interesting is that initially I thought it might be bit too big for me but I've since swapped the stem for 2cm longer one and set the saddle a notch further back. Also, during the time I've had the Rossin, I've bought and sold bunch of track frames because they all turned out to be way too small for me. Live and learn.
