Ian A, I believe the S1 and QB geometry is the same; however the largest S1 offered was a 62.
Regarding differences, the S1 was made in Taiwan, has a kickstand plate, and some (all?) came with cream accents. I've not found anything definitive on the tubing used, but some say the QB's tubing was a tad lighter. My (used to be Ben's) S1 has 42mm Continental Contact Speed tires and would easily take a 44.
