You find probably the best workshop in the whole country here. It's 20 km south of of Malaysia's capital Kuala Lumpur. At the University "UPM" in Serdang. The workshop is run by Akmal, a total cycling lover with lot's of knowledge about everything around the bike. He has pretty much every single tool you need to make your bike blink and shine again after thousands of kilometers touring. He lives and works in the workshop. Usually it's also possible to stay a few nights there as well.

Tell him Hi from the two Germans and the one broken arm if you meet him :-) We had a wonderful week living in his workshop: http://querfeldeinerichtung.wordpress.com/2013/06/10/katzen-auf-fahrradern-cats-on-bicycles/
