Handlebar Shims

Color+ Shim From/To + Length:Stainless Steel Nitto 25.4/26.0 35mm

Oh shims. 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, it'll slip, we promise.
We stock 31.8 to 25.4 + 26mm silver and black shims from problem solvers and blue lug and velo orange (whatever is in stock that we can get our mitts on)  and 26mm to 25.4 steel shims from Nitto.


You can ride these off road, if you follow our do’s and don’ts.
