I really like my 1Up rack as well. Fits all manner of bikes. Super solid. Bike on and off in seconds. Same for for the rack which can be good or bad. Agree that it looks like someone cobbled it up in metal shop.
@Patrick Since you have one and are the resident mech guru - question regarding disassembly. I have a first gen rack I bought on here which had one of the blue rotating tabs tweaked, cracking the center plate. I got the replacement parts, but find that the countersunk screws securing the plate use a small hex size and the screws seem to be really stuck - galvanic corrosion? I'm pretty close to stripping the hex area in the screw. Tried heat, PB blaster, no luck. Any suggestions? Was thinking to just have at it with an EZ out.
ez out. i think the sunken bolts are al, so it should break free without a problem.
might try heating it and letting it cool down a few times. not ripping hot, just enough to get the receiving side to expand/contract a couple times.
gl - report back!
