Technical Q&A with Lennard Zinn – Murky water, nasty roads
Dear Lennard,I have an ’04 Specialized S-Works E5 frame. I’ve noticed after a ridein the rain when I tip the bike up some pretty murky water runs out thechain stays near the rear wheel. Last night I was changing my bottom bracket(the new Dura-Ace 10-speed, if that matters) and it made a nice little pondon my garage floor. Since water and probably some nasty road salt, gritand grime are getting into my frame, do I need to strip it down on occasionand flush it out with some clean water?MattDear Matt,Yes, that is a very good idea. Also, a drain hole in the bottom bracketshell is a good idea – or
