Quick question... anyone know if it is possible to mount the low stack kit *under* the base bar with the cup/pads mounted directly on the base bar (lowering the overall stack by the thickness of the low stack extension mounts. The bottom side of the base bar has the same flat spot near the mounting holes so it looks doable but just not sure if there is a screw/bolt combination that would make it work since the base bar is part with the threads (right?) Maybe a screw from the bottom through the low stack mount and a screw from the top for the pads, but they would have to be shorter than normal since they would only be able to thread 1/2 through the base bar. Anyway.. just a thought and I was curious if anyone has attempted this.
out of the box, it won't work. but maybe possible with some modding.
there is a couple of issues with it.
1) the whole basebar/shim/lowstack mount are all countersink/inverse-countersink so they fit into each other. the bolt is also a countersink bolt that fits into a countersinked hole from the bottom of the basebar.
2) the arm rest is mount onto the lowstack mount via separate holes. if you put the lowstack under the basebar, then there is no hole to mount the arm rests.
now there multiple potential solution to this problem. all require a bit of tweaking.
1) you can invert the whole thing. now the basebar/shim/lowstack will mount like it used to. there are 2 issues: a) arm rest still have no where to go; b) the basebar handle/brake lever will now point downwards (you can cut it to have it horizontal.. but probably not advised.
2) you can keep basebar right way up. you probably need to add some homemade shim between basebar/lowstack just in case they don't interface properly. you still have the issues with the armrest having no where to mount to.
the armrest probably need to be solved in either case, since the mount point is on the lowstack which is now under the handlebar. possible to fabricate one i guess.
