Ok, so a recent eBay purchase left me with this. Clamp marked 34.9, but when it was WAY too big for my seat tube I looked closer. Other 34.9 clamps fit the bike just fine.
To my untrained eye it appears that someone went to the trouble of making a new hinged clamp band on this unit.
The edges are squared off compared to the rounded surfaces everywhere else, the finish is also different - without the polish present on the rest of the unit. A google image search confirms this.
The seller is being very cool about it, and I'll probably return it since it doesn't work - but someone (before them) went to a lot of trouble to do this - and they did a pretty decent job.
Was there some brand way back then that might have had these made for a non-round seat tube? Anybody have any ideas?
