In his May 21 Outspoken Cyclist interview, Rob English talks about his education, his Obree tribute bike and why tiny seat stays are a lot stiffer than many people might think.

..."These are terms that have an engineering basis that are bandied about by marketing and the press without really giving them any data. To my mind, if you're going to use a term you've either got to say this is entirely subjective or you've gotta put some numbers behind it. The people say 'this frame is more compliant than this frame,' and I'm like, 'well, is it? Or have you got a different seat post, different saddle, different wheels, different tyres, different tyre pressure, are you wearing the same shorts as when you rode the other bike?' The human perception of what you're riding is so subjective and so it frustrates me when people look at a bike and say 'oh, it's got small seat stays, it must be compliant,' but no, the triangle is a rigid structure by definition. If someone tells you they're getting some compliance out of their rear end, ask them for some data, the deflection numbers, to prove that's happening," said English in his interview with show host Diane Lees.
