As the number of bikes in the house grows, storage becomes more of a problem. I have some hooks that I hang my touring bike and the gravel bike on (hanging from the front rim), but they both have durable aluminum rims.

I now have to find a way to store a new all-carbon road bike, one that has aerodynamic carbon rims, a carbon seat-post, etc. I don't want to leave it sitting on the floor, lest I forget to keep the tyres pumped up. I don't want to hang it from a hook, since I'm sure that's not how the rims are expected to be loaded. I could use a clamp to hold it by the seatpost, but again since that would leave it under a certain amount of torque for months, I'm not comfortable with it.

A quick search didn't turn anything obviously better, and I thought it best to ask for suggestions before trying to bodge something together.

    Dedicate a bedroom for bike storage? Clean out the garage and sell/dump/give away some things you don't need? Build another garage/shed for bike storage ? Buy a bigger house ? – Criggie Sep 28 '20 at 21:26

Vast majority iof carbon rims will be fine taking the weight of a bike. If yours have very fragile fairings and its not suitible, a couple of options that are common come to mind.

Hang from bars and seat https://tradetested.imgix.net/catalog/product/_/0/000bom-bike-ceiling-hoist_ceiling_storage_hoist-1_bike.jpg?auto=format&h=1300&w=1450&fit=fillmax

Hang from frame enter image description here

Can't find an image - hang from handle bars with seat to the wall and wheels sticking out, can hang from just the seat. You can get any style of brackets from very cheap and agricultural to art pieces that match the most upmarket apartment to hold the most hipster single speed you can imagine in the style you would expect.

  • Ooh! I like that last one!! I could even use my existing spare hooks, I'd just need to bolt some scrap pieces of framing lumber to the wall to screw them into. (That also puts the handlebars opposite to the others that are hanging by their wheels, so I can pack them closer together.) – DavidW Sep 28 '20 at 21:03

    All you need now is a significant other cool with a living room full of bikes – Argenti Apparatus Sep 28 '20 at 21:52

    These option adhere to The Rules, #49 "It is completely unacceptable to intentionally turn one’s steed upside down for any reason under any circumstances...." – mattnz Sep 28 '20 at 22:22

I don't see a problem hanging a bike from a carbon fiber composite rim. The amplitude of the load would be much, much lower than when riding over even moderate bumps. OK, the load is radially outward rather than radially inward but the wheel is not weak in that direction.

Maybe of the inside edge of the rim is particularly narrow in profile you could damage it, but suitable padding would prevent that.

  • I think David may have been confused with rims with non-structural carbon fairings, e.g. the Hed Jet. Those are definitely not safe to hang by hooks, and I believe that roof or trunk rack straps might also be a concern. These represent a minority of carbon wheels, especially with the advent of disc brakes. I believe you're correct that most carbon rims can easily withstand a hook. – Weiwen Ng Sep 28 '20 at 19:21
  • The inside of the rim is quite narrow; the bearing point accounting for roundness (both the rim and hook) would likely be under a few mm^2. Perhaps I'll look into forming a conforming support from hard foam. – DavidW Sep 28 '20 at 20:54

Some carbon wheels, like the Hed Jet and the Bontrager Aeolus Comp, have an alloy rim, and a non-structural carbon aerodynamic fairing bonded to that rim. "Non-structural" means I can bend the fairing by pushing it lightly with my finger. I've tried this (very lightly) on my Hed Jets. These wheels certainly can not be hung by hooks. That fairing is designed to do nothing apart from modify the airflow. The spokes go through holes in the fairing.

In most carbon wheels, the carbon is structural, i.e. it's full carbon construction that has to resist the pull of the spokes. These should be more than able to withstand the weight of the (presumably light) bike. Pad the hooks if not already done so.

I don't see a real issue with storing the bike upright on the floor unless you have tubular wheels. With my cyclocross tubulars, the recommended best practice was to hang the wheels, lest side forces dislodge the tubular from the rim entirely or just force it off straight. With tubeless wheels, if you let the wheels lose air entirely, you might need to ensure the tire beads are seated properly in the center channel before reinflating. If the tires got dislodged, I suppose it's possible you could spill sealant.

  • The rim is structural carbon, so that's not an issue. As to not storing it upright, it's partly (and increasingly) a matter of limited floor space; if I don't get it off the floor I won't have space for the workstand... :) – DavidW Sep 28 '20 at 20:59

    Sling a broad strap around the front hub and hang it from there. Or just replace the front wheel by an unserviceable front hub/wheel from the LBS's junk and store the carbon wheel separately. – Carel Sep 29 '20 at 7:44
  • Ooh, I like the front hub idea! – user7761803 Sep 29 '20 at 13:57
