On the [url=http://www.kingstonwheelers.co.uk/kwccforum/viewtopic.php?t=9995&postdays=0&postorder=asc&start=105]Kingston Wheelers[/url] forum I noticed a rather lively thread on 'wheel sucking'. Wow i didn't realise how much it peeves some people off. Before reading the thread I'd never given it that much thought. In my own case I may sit off someone wheel briefly (never real close unless I know them or its an official group ride) but I don't stick there religiously mile after mile unless I'm suffering. And in such cases I'll apologize after a short while and check if their OK about it.
On the other hand if someone sits on my wheel it doesn't bother me in the slightest. If we're evenly matched we may end op taking turns. If not they usually spur me on to ride harder but I will make my slowing, stopping, turning etc very clear with official ACC hand signals . What does everyone else feel about a stranger jumping on your back wheel?
