Riser Bars with 26.0 mm clamp diameter...where?
 

Where can I find an affordable (between 10-30) riser bar with a 26.0 mm clamp diameter?

also I noticed the higher you put your stem the easier it is to do bunnyhops!

get a MTB riser bar and shim it.

As far as I know, all mountain bike bars are going to be 25.4. I would advise buying a 25.4 stem (any mtb stem, some nitto road and track stems) and any old mtb riser bars. If you already have a 26.0 stem, buy any old mtb risers and shim the bars with a beer can. If the beer can shim disturbs you, Nitto makes some fancy stainless steel shims to allow you to run 25.4 bars with a 26.0 stem.

On a tangent: I often see deep drop stems paired with riser bars. I hate that. Buy a stem with less drop and run a flat bar. You can get the exact same hand position with less weight. If you want a sturdy and swept back bar, buy a surly flat bar.

and more places to grab the bars. holding on to the risey part of the riser bars is no fun at all.
