This is the method I've used to insert shims (which -- as others have said -- work great once installed) as well as handlebars.
https://janheine.wordpress.com/2012/01/17/inserting-a-handlebar-into-a-stem/ It works perfectly, and the little nut/bolt/dime jig holds the stem open so you have both hands free to position the shim. I haven't found the that the masking tape is always necessary. Hope this helps, Eli -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
