I recently switched over to some Soma El Toro bullhorns on my Jamis Sonik (which I adore) and I want the option of mounting my aerobars (Profile Design t2+, which I also adore) when going on longer rides, etc. I currently have the aeros mounted on some drops that are 31.8 at the clamp and don't taper for a while so there is no problem at all and currently when I want to use them I just swap out the bars. I'd like to be able to put them on the El Toros, however, the El Toros are 26.0mm clamp (which I have shims for my stem that work fine) and they quickly taper to 23.8mm diameter...
So basically I need some way of either getting a shim from 23.8mm to 26.0 (the aerobars came with specific 26.0 shims that could do the rest of the work) and be double shimmed (which I really would rather not do). Or find a shim that is from 23.8 - 31.8. I've been searching around for a while now and can't really find any thing.
Anyone know a DIY solution that isnt too sketchy for shimming? Or have better google skills than I to find a 23.8-31.8 or 26 shim? Its not the end of the world if not since I only want the aerobars maybe at most once a week or so, not daily use. But it'd be nice, ya know?
Thank's all, hope this isn't too dumb/petty.

Why not just try to find another stem that fits your needs and keep it mounted to the El Toros?
The stem's fine, its the fact that the El toros taper to 23.8 and thats too small of a bar diameter for the aerobars to hold onto, and a shim that size doesn't seem to exist anywhere. Sorry for the confusion.
