cat 6 rules should be more generic. Ride what you have, be it a roadie in full kit with a backpack, a cross/touring bike with rack and panniers yellow jacket and blinkies, or a mountain rigid on knobbies or full fred upright bars.

The key would be to hammer relentlessly, attack off the wheel unexpectedly (usually masking any hard breathing by giving a lazy "mornin"), and chasing down anyone seen ahead.

Geriatrics on three speeds, prepubescents on bmx, clydesdales on walmart specials, safety-nannies in full day-glo and bearded recumbents are all equally valid "kills" for the day's tally.

Cat6 = Attack! Close the gap, never show pain, attack again, cheat the wind, dont merely pass them, drop them, slow for nobody, look 'em in the eye and ride off the front! . . . but. . . if you get dropped or passed, remember, its just a commute and not a race.
