Oh my goodness. Now you've gone and done it. You mentioned the "T" word. Good that you didn't make the mistake of posting this in Road Cycling.

Everyone knows that you'd be 10 to 20 miles per hour faster with a compact double, not to mention they are several pounds lighter than a "T", and "Ts" can never be properly adjusted and you'd win the TDF if you'd just use a compact double etc.

I've been unashamedly using "Ts" for years and love the versatility.
