I agree. I also have hung bikes by their rims for extended periods of time with no problem. I have had more problems with bikes sitting on their tires, slowing losing air, and as a result flattening, then cracking the tire. I have recently bought some fixtures at Home Depot which have two arms that fold out from the wall. The bikes hangs from the top tube on the arms, like on a Hollywood rack. I like this setup. You get a nice view of the bike, it doesn't sit on its rubber, and you can pedal the bike while it's hanging. chris ioakimedes Fairfax California -----Original Message----- From: classicrendezvous-bounces@bikelist.org [mailto:classicrendezvous-bounces@bikelist.org] On Behalf Of Steven Willis Sent: Friday, April 02, 2004 9:03 AM To: FujiFish1@aol.com; classicrendezvous@bikelist.org Cc: tadams@ns.sympatico.ca Subject: Re: [CR]Hanging bikes ... and potential wheel stress

Think about how a wheel is made. The spokes are keeping a rim pulled in. When you ride a wheel the spokes loosen up when they make contact with the ground. That is why when you take a hit it sometimes will start a wheel loosing up the spokes. When you hang a wheel the load goes from the rim to the spokes to the hub. Very strong in my opinion. I have been building wheels for over thirty years and have had bikes hanging almost as long, never enough time to ride them all, and have never had a problem with anything except scratching the rim when the coating come off the hook. They only other problem that does not work with hanging is some MTB suspension forks can leak oil if you hang them.

Ah, but doesn't a wheel rim in use get a lot of its strength through the principle of an arch ... i.e, pressure from contact with the road is spread over a larger area with the use of a tire, and pushes into the CONVEX curved side of the rim (the "arch"), which pushes onto itself for support. Much like a brick or stone bridge built with an arch. On the other hand, doesn't a hook pulling OUTWARD on the CONCAVE side of the rim, pull in the weaker direction for the rim, AND in a much more concentrated contact area, which is just the opposite of when in use? That's my thinking when I look at my bikes hanging there, wishing I could see them better, and it has bugged me a bit. I too want to protect all these beauties that I have invested so much time and love into, as best I can. The wood stands that were discussed made me think of a more permanent application for my basement gallery. The plan will orient each bike in the correct position. They will be supported by the top tube, cradled in a nicely curved half tube, lined with soft stuff for years of paint-safe use. They will be "riding" off the wall at 45 deg. or so to the right, displaying all the Campy cranks and gears ... whoopee! Once employed, I'll take photos and email the list.

I do not know about you but I weigh way more then my bike does and my wheels hold up fine with my big body on them. Hanging is fine just use coated hooks so you do not scratch the rims up.
