That's not correct. 2nd gear is 1 to 1. It's similar to the AW except for wider range.

It's not that they're fragile, but that they tend to skip, particularly in high gear. I've got one of 'em myself on a "Q ship" Raleigh Sports with a full chaincase and lightweight 27 x 1 wheels. I've got it geared pretty high, so I don't wind up using high gear all that much.
