This custom handle was built by brycer1969 on a rail adapter. It’s super stiff, straight and ready to go on your Muni. In addition, if you have a KH handle, or plan to get one, you can probably cut off the handle part and it should slide into the KH handle mount.
If you’ve every wanted to try a handle, this one is a great way to start.
27.2mm rail seat post included.
Seat NOT INCLUDED (Included pic of what it looks like with saddle attached for perspective only)
