We were on hols in Koh Chang when it happened. I take a morning ride a few miles to a posh resort and plonk myself on a sunbed for ten minutes or so. When I got back on the bike and started pedaling, that's when it gave way. Luckily nothing hurt but my pride, and no one saw it, and it was the last day of the hols. Left the bike lying there in disgust whilst Mrs Crank was summoned to rescue me in the car. She took ages getting to me as it was quite early. The resort is exclusive for Russians, and by now a few were up and walking past giving the bike strange looks and wondering what happened. Anyways, I'll strip the bike of all its parts and recycle them onto another project. I've got a Raleigh Twenty here that'll be my new travel bike - over engineered and built to last, they knew how to make a sturdy bike back then that's for sure
PS - The break looks clean, no track of failure. With steel you get some warning of imminent failure, but aly is different, and then there's carbon
