So not a question of etiquette then, simply courtesy. I guess next time I’ll just have to drop down the cassette and give ’em a run for their money.
And therein lies the answer. If someone doesn’t like you on their wheel, they can always try and drop them. If that works, sweet, if not, the tailer will get bored after a while and pass.
I would say if you’re going fast enough for someone to *have* to stick on your wheel rather than passing then you’re probably up for a race anyway. I know I am. Nothing makes me happier than looking round and seeing someone there (edit: although in reality this has only ever happened after I’ve passed them first), waiting. I don’t care if they beat me in the subsequent sprint, it’s all good fun.
