For me its rossco's pic. Looks like it could have ended nastily! Reminds me of the bridge over the road through the centre of the Malverns. Good times.
Ta for vote EarlofBarnet. It did get a bit sketchy mid flight but I did manage to get it rubber side down.
If I do say so myself, I do like my own photo, but my vote has to go to The Ken. Might not be true mountain biking, more council estate biking, but I remember jumping my Raleigh Commando, amongst other bikes, off any obstacle you could find.
Broke every bike I owned upto when I was about 14. Some bones too....Ahh they were the days. You just don't see kids building ramps out of planks of 2x4 and broken bricks found in the bushes anymore.
Its all nerdtendo pswii's and texting your mate who's stood next to you these days....I'm starting to sound like me dad
