while I am not going to build a bike like that, I really do think he has good work with it. The guy has other bikes to ride too, someone has to have the lightest bike, don't they?

The fact that there is a photo of him riding it says a lot. In fact i'd bet he is in better fitness than 99% of the folks having a go at his bike also.

Some peolpe have old bikes, some have lots (mtb, track, road, bmx etc) others collect lightbulbs or stamps or even spend huge amounts of money on old cars that are rubbish compared to more oor less anything modern.

wow, let it go folks. He does more than look on the internet and buy bike parts and bolt them together.
