Another take, Cav is so shit as an all rounder if he were dopeing his keeping up with the Pelaton would stick out like a sore thumb.
I’m not having a pop at Cavendish here, just using him as a (hopefully) clean example of a cyclist who is by far the best at his speciality and will therefore attract the inevitable attention and whispers.
BTW he can and does keep up with the peleton (and even worked hard on certain stages for teammates in the TDF) otherwise he wouldn’t complete tours and win stages! Mind you, if he started winning mountain stages………….
