The button heads on the included longer bolts in the Bikeman spacer kit didn't clear my White Brothers fork.
The fork was purchased one year ago. I am using an Avid HS1 rotor, which is a little thinner than the G2 & G3 Avid rotors. My hubs are year old Salsa 2.
The silver colored bolts included with the spacer didn't have thread locking compound applied. With a thin coat of blue "Locktite" applied the bolts threaded into my year old hub a little to easy for my peace of mind. By that I mean by-hand all the way. I tried the bolts in other hubs with the same super easy to thread-in, almost loose, feeling.
Other than the bolts I was pleased with the spacer's looks, fit and feel.
I am in search of thicker, fast-drying, blue, thread locking compound and longer Ti rotor bolts with a flatter profile head.
