riding in flood water, my friend and i went into a drain with heaps of water, like a small river, it was over our front hubs, the current was too strong to get out, the water pinned us up against a bridge, i bailed and let my bike float towards death, my friend stayed pinned to the bridge now with 2 bikes stuck on his legs, i had to pull him up onto the bridge. as it was a low foot bridge, the bike rubbed up against the concrete on his stauntions for a while before we lost it in flood water for about an hour. we found mine straight away.
hahaha, similar thing happened to me, but no bike damage or loss, rode into what I thought was 1" deep water, came up to my waist (while on a high seated XC bike, I'm 6"6' so that gives you an idea of how big/high my bike was), current was ridiculous, so was the drag. Had to granny gear that shit for about 20m, took me over 5 minutes and the lactic acid burn when I got out made me spew. Wasn't sure what would have happened if I'd hopped off with falling over etc..having a fair amount of valuables in my bag and all didn't help.
Bad. Don't ride through flood water, even if you know the passage underneath, it still could be brutally tough and deep!!
Another time I watched a guy as he proceeded to "lube" his chain with WD-40, he also accidently lubed up his rotor which I didn't see haha, fool. Then we went out, the hill right next to his place goes down at a nice angle, but it's only a shortcut to the trails, and is really grassy.
*puts on back brake; nothing*
*puts on front brake to compensate back brake's lack of brake; over the bars and rolled about 10m getting totally coated in grass and shit*
Then his bike came to party, with his head, 4 stitches later he decided WD-40 wasn't good to lubing bikes.
So good.
