So I recently got a Topeak Handlebar Extender that I put my computer (light little cateye wired strata cadence), airzound, and cateye headlight on. Today was my first ride with it on and, at the end of the 2 hours (maybe 30 minutes was grocery shopping), I was maybe half mile from my house and the stem on the thing connecting the extender to the handlebars snapped and the extension dropped down. Fortunately the hose from the airzound and the wire from the computer kept it out of my wheel, but as my rear was overloaded with about 40 lbs (I counted because that's the limit of my rack and if you count my wald baskets I overloaded it) and I was going pretty fast down a hill so I freaked a bit but kept in control. Brand new extender gone.




I'd thought that stem was metal, but by looking at the cross section that's obviously not the case.

Anybody have some suggestions for one that's sturdier and won't fail on me on the first ride (or hopefully any subsequent ones)? And hopefully won't break the bank?

Or was I just unreasonable in what I wanted it to hold?
