HH, not for nothing my friend & this is not meant to be an insult, flaming or trolling. But your posts about BL's are getting as bad as mine about helmets. This is turning into what others have called a "dead horse" issue. I'm not saying to stop posting about them, I won't stop posting about helmets if I feel it is appropriate, I imagine you feel the same way.
just expect satrical comments from me & others as well as serious comments similar to what I have received about helmet threads.
And BTW the second part of my first response to this thread is meant to be serious. Why do that & why require speedometers on bicycles?
