Got my tinman sideracks earlier this week and took a few minutes to put them on. I dont think I will ever take them off except for doing maintenance so I replaced the hand knob nuts (or whatever you call them) with regular nuts. Dont have bags to put on them yet but will soon. The entire cyclerack/tinman rack is so solid its as if its one with the bike. I like em a lot. Oh, got something else from him he wanted me to try out, can you guess what it is?
