Brake Stud Light Mounts - 22mm diameter mount, about 38mm of clamping area. These came from our kinsman Greg at Calhoun Cycle here in Minneapolis. I was all excited for our QR Nut Light Mount; he thought it was okay...but immediately asked if we would consider doing a brake stud mounted version. Done and done Greg (sorry to keep you waiting; your set is on the way!)
I've been waiting for this one for a while. New and in-stock at Big Momma QBP. Call your local bike shop to order up a pair!
