The other day I realized that the handlebar binder bolt on my stem had a nearly-stripped head, enough that it took an SAE size key to loosen it. My bike is an '83 Miyata 210, a $25 CL find back in late August (thanks again Bill), so it has a few issues like that, no big deal. The bars are the original SR Sakae 'Road Champion' with the charmingly spelled 'RANDNNER' designation. They are kind of narrow so I have been looking for a (cheap) wider replacement, and have just left the original foam wraps on them.
I went to the LBS today (Uptown Bikes, salute) and got a new bolt along with the proper seatpost binder the bike needed. Even got some bar tape for my eventual first-ever bar wrapping.
So I put the bars to the angle I wanted, tightened the bolt, went for a ride, switched from drops to hoods and...the bars slipped and rotated down. Not in a dangerous way, but just kind of a surprise.
When I got home I tightened the bolt again. And again. And again. And still each time I found I could make them rotate around.
When I pulled the foam back I found the problem: the bars are not one piece. There is a central sleeve, which has the Sakae text on it, and the rest of the bar (duller finish) is within that. So I am tightening up the sleeve but not really tightening the bar.
Why in the world are the bars this way? Is there a workaround? Any suggestions?
There's a set of the same bars on eBay.au where you can see the difference in the metal finish in the sleeve. Sorry but can't grab the pic by itself. http://cgi.ebay.com.au/ws/eBayISAPI....m=390107202954
There's a C&V ride tomorrow and I simply can't show up with my handlebars at the wrong angle!
Thanks for any advice!
