Coker handlebar woes

[FlyByTire]

I just received the new Coker handlebar and am having trouble with installing the thing on my Coker Big One that I bought earlier this year. Here's the handlebar...



The problem is that the inner diameter of the clamp that goes onto the seatpost is slightly smaller than the seatpost itself. I have the aluminum seatpost from Coker, rather than the steel version. Has anyone else had this problem? I tried to force it on, but you can see the results below. In the process of trying to get it to fit, both the clamp and the seatpost were damaged. I tried prying the clamp open, but any attempt to do this just damaged it more by gouging the aluminum through the painted surface. It springs open and then immediately back again, so there is no point were I am able to slide it cleanly onto the seatpost.

Has anyone successfully installed the handlebar on an aluminum seatpost from Coker?

Thanks,
Aaron

Hmm, that's strange indeed! The OD for the coker seatpost, whether alum or steel is purporedly 25.4mm. They should be identical OD. The only thing I found different with the big one, compared to my radial in that area, is that the big one's Seat *tube* OD requires a seatpost clamp that is 27.2mm!

This is because the alum seat tube's OD is significantly thicker than the radial's steel tube. But again, the *seatpost* OD 25.4mm should fit the ID of the coker handle, but apparenltly there is a discrepency between the alum and the steel seat post OD's, which should not be-if they are *both* 25.4mm. (I guess I'll have to find out for myself as I just got a call from Jamey of uniproshop, informing me that my coker bar has been delivered!)

Thanks Terry. I look forward to hearing how yours fits. Do you have a steel seat post, or alum?

It's a KH rail type and I think it's chromo.

I'm a bit confused. So, the new coker handle is designed to fit over a 25.4mm seatpost? So I could buy one and put it on my Nimbus fr ame? I've been wanting a handlbar, and this one looks better for my uses than the T7.

Also, does the coker handlebar act as the unicycle's seatpost clamp? Or is it supposed to slide up under the saddle?

Sorry haha I guess I should not have confused the issue by mentioneing the seat tube, lol.

But yeah, both the new coker, the nimbus and the radial all use the same size seatpost: 25.4mm. So it shouldn't matter whether the post is alum or steel. As long as its OD is 25.4mm.
