JONES H-Bar Shim Set
This is a set of two shims to make a 25.4mm handlebar fit into a 31.8mm stem.
These wide shims extend out past the stem clamp on each side to reduce the chance of crimping or gouging of the bar from a crash or from over tightening of the stem by spreading out the stress over a greater area at the edge of the stem clamp.
Stem clamp surface width is 45mm
Overall width is 66mm
CNC machined aluminum, anodized black with laser etching.
For use with all H-bars that have a 25.4 mm cross tube or for converting any older 25.4 mm bar to the current 31.8 mm standard.
The new Jones H-Bars are now built with a 31.8 mm center section and do not require the shim set.
