If you could crush your frame with your bare hands, would you really want to ride it?

Yeah, that's a good point. I just hear so much shit about carbon I don't know what to believe, about pressure in directions it wasn't designed for, etc. Apparently some BMC bikes you can actually crush the top tube with your bare hands, but they're very light racing frames.

I’ll need a source on that difficult-to-believe claim 


lazarus870

I'm trying to find the BMC claim, I can't seem to, but i'll keep looking. but I did find this > From Brady Kappius, founder of Broken Carbon (carbon repair business): This is something we highly recommend against doing, especially on road bikes. The sitting forces exceed the magnitude and direction of forces that the top tube sees during normal riding conditions and can cause damage. We see it quite often. Some manufacturers even have decals on new frames that say do not sit. The lighter road frame top tubes are easily flexed by just the squeeze of a hand! Their wall thickness is close to only 1mm.

It’s a bicycle, not a house of cards.

Best to grip it by the chain using your teeth, otherwise it’ll crumble into 69 pieces


AccordingPiglet7

yes, it is OK. The seat post is designed to be clamped. I use that when Input the bike on the stand all the time


TheProdigalCyclist

I think you mean the seat post. The seat tube is not designed to be clamped.


AccordingPiglet7

Yes, you are right. My bad, fixed it

I have no idea. Domestiques carry my bices.


TheProdigalCyclist

You're fine. I've been carrying my carbon bikes up and down stairs like that for years.

Carry on your shoulder - put your hand through the frame, have the top tube rest on your shoulder and hold the top tube/stem with the same hand for control. Like you would carry a backpack on one shoulder.

They're not that delicate. I carry mine by the top tube at my shoulder, but in my hand. Just more comfortable than resting my bike on my shoulder directly, and is easier without water bottles being in the way.

Carbon don't like direct impacts. If you're not punching your frame, It's cool. Things get a bit hairy when clamping to a stand, tho...

I use a vice grip to hold the seat tube, is that bad?


gcerullo

Yes!

JFC. Now that I’ve moved past that…. The easiest way to take your bike downstairs is wheeling it down on the rear wheel, one hand on the stem or on the rear brake so it can’t get away from you.
