Jesus, what a load of fuss!You can always TALK to people you know, maybe say 'I'd rather you didn't draft me' or 'Get on the back, mate'....
I think some are missing the point of my OP. I'm not a roadie but bought a road bike to get some fitness back. I don't know the roadie norms & I didn't know someone was on my back wheel until I heard the 'oh shit *smash, crash, aaaargggh* ouch'
