hey everyone. i've got a bike with regular 1 inch threaded fork, but recently switched to 1-1/8th using a stem adapter. now, being that there's no top cap or star nut, it's just the stem gripping the adapter's neck, it tends to slip fairly easily.
anybody have any solutions for me here?
the only thing i can think of is taking some gritty sandpaper to the adapter and the stem to maybe rough up the surface and offer it some friction but i'd rather not.
