Oh shims. So denigrate. So misunderstood. The woeful life of an underrated bike bit.
Here’s the stem shim low down. They work fine, if you use ‘em right.
Use them with 2 or 4 bolt stems
Use them with steel or aluminum handlebars
Use a shim that is wider than your stem clamp
Do torque your stem bolts properly
Stack shims. IE don’t use a 31.8 to 25.4 shim and then a 25.4 shim to a 22.2 shim on the same stem. That's a recipe for failure.
Use 4 piece shims.
Use a shim with Bosco bars
We stock 31.8 to 25.4 + 26mm silver and black shims from problem solvers and 26mm to 25.4 steel shims from Nitto.
You can ride these off road, if you follow our do’s and don’ts.
