i'm 70kg. when riding w diesel, I have to slow down on the climbs and pedal hard on the downhills. this implies Dan is big. constant wattage (or w/kg) doesn't stay tight. and if you blow out of the 'band' you have to start over on the drops multiplier and you won't get virtual kit that you don't like. which is also fine because its. just. a. game. dammit.
