Perfect for all your bike accessories
6 sizes:

  • 1 1/8-inch for handle bars, seat stays, etc. (minimum diameter 3/4 inch) 
  • 1 3/8-inch for steel frames and forks
  • 1 5/8-inch for 32mm suspension forks
  • 2-inch for aluminum tube bikes, 36mm suspension forks, etc.
  • 2 1/4-inch for bikes with larger tubes
  • 2 1/2-inch also for bikes with larger tubes, or get creative!

Sizing is for the maximum diameter

We suggest electrical tape or cloth rim strip to protect the frame or fork legs. Rubber inner tube will lead to clamp breakage. Tighten clamp after use.

Doesn't work with the Salsa EXP Cage - The plastic on that cage it too think.

Great product

Really clever solution to adding mounting points where there are no braze-ons. I was able to add a rack and fenders to my Klein Quantum TT which doesn’t have any besides the water bottle ones.

The only thing I might change is making the bolt a bit longer for attaching thicker supports, could barely get the nut on a couple of my rack support arms.

support bolt

Works well.

Good Enough!

Just a pipe clamp with a tab tack welded on and a small bolt. The band is narrower than it looked in pictures, but it works.

What a great Idea!

Very pleased with the Universal Support Bolts. I added 2 water bottle cages to a touring bike for an adventure on the Ohio to Erie Trail. Very practical idea- i can see a lot of applications for it. Thanks!

Excellent Strong Support

Mounts worked great on mtb forks for a trip. Mounted 2 gear cages with bags.
Even over rough terrain no slippage or movement.
