You’re absolutely right. I have the original roller cams from my Cannondale but I’m missing the studs with the male thread (see top right hand corner of the montage) but by using the Brake Stuff stud Pierre’s friend should be able to use a standard M5 bolt (I tried it this morning) and if he’s not happy with it protruding then he could always increase the rebate depth on the spring tension bolt (see yellow arrow). What do you reckon?
