They are too flexible/flimsy for that application. A reason we no longer even stock that cage (at our shop).

I once rode a couple miles wondering why I was sucking air so bad, thinking perhaps I was either having a very bad day, maybe overtrained, perhaps the air quality was worse than usual. Stopped to take a break and in rolling the bike to remount found the back tire dragging against the left chainstay.Ronsonichttps://www.blogger.com/profile/03084095209525920755noreply@blogger.comtag:blogger.com,1999:blog-13887692.post-87955467094264342792009-08-21T13:14:22.071-04:002009-08-21T13:14:22.071-04:00Density of orange juice? that is so nerdy.Density of orange juice? that is so nerdy.cwghttps://www.blogger.com/profile/11815585725243317055noreply@blogger.comtag:blogger.com,1999:blog-13887692.post-4773797904878619152009-08-21T10:47:13.327-04:002009-08-21T10:47:13.327-04:00Gsport : I know it cracked because of the overload...Gsport : I know it cracked because of the overloading of one of the mounting holes since the other screw was missing. How it went missing is beyond me but that doesn't matter now. Surely this is a bizarre event to happen to me :) but I think I'm to blame for not checking my equipment. However, like I mentioned to someone else before in the comments section, it would be nice if the cages had a tad bit more base support for the bottom of the bottle.Ron Georgehttps://www.blogger.com/profile/18394865788996482667noreply@blogger.comtag:blogger.com,1999:blog-13887692.post-60007273547891765692009-08-21T04:57:54.994-04:002009-08-21T04:57:54.994-04:00Well I just poured Tropicana ("with juicy bit...Well I just poured Tropicana ("with juicy bits") into a measuring jug on a zeroed digital scale (accurate to about 2g). 1/4 of a litre weighed 250g, which is a relative density of 1 and exactly what I expected... Perhaps fancier grades of squeezed orange juice are denser though. Perhaps you can weigh your brand that was involved in the incident?<br /><br />Even then I think that a 20% overload should not have broken the cage on its own, perhaps the cage was never designed to be mounted overhanging like this and it has slowly fatigued the plastic at the crack point and the subsequent loss in structural integrity has allowed the cage to flex and take the tension off the mounting screw which subsequently worked loose and fell out...gsport georgehttps://www.blogger.com/profile/10070707288565019602noreply@blogger.comtag:blogger.com,1999:blog-13887692.post-55442701125583938332009-08-20T22:01:36.651-04:002009-08-20T22:01:36.651-04:00plastic cages suckkkkplastic cages suckkkkAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-13887692.post-6359531684461111462009-08-20T21:46:30.306-04:002009-08-20T21:46:30.306-04:00Gsport : Good question.

Orange juice does not contain rind. Rind is thick and porous helping oranges to float because of pockets of air. The theory of why they float is consistent with that of pumice rock floating in water. <br /><br />As to the value of 1.2-1.25, I picked that up from someone who already measured the density using simple Archimedes principle. See : http://wiki.answers.com/Q/What_is_the_density_of_orange_juice_with_pulp. I don't know what the errors are in his calculation but I judge it must be close to the density of water but still higher.Ron Georgehttps://www.blogger.com/profile/18394865788996482667noreply@blogger.comtag:blogger.com,1999:blog-13887692.post-68532323459078228632009-08-20T20:32:18.745-04:002009-08-20T20:32:18.745-04:00"...The density of orange juice with pulp is ..."...The density of orange juice with pulp is more than that of water, about 1.2 to 1.25 g/cm^3...."<br /><br />REALLY?!?!?!?<br /><br />That seems massively unlikely to me, do you have a source?

Any plastic cage I've used has cracked sooner than later, my carbon ones have been great for several years and they've taken some good hits<br /><br />The carbon ones I've got hold tight, they don't rattle, etc, etc.<br /><br />The only risk I can see is they could cut you bad if broken during a serious crash.<br /><br />Lesson learned as well why MTB'ers favor hydration packs for more than just hands free operation.<br /><br />As another anecdote of wheel rubbing - I was cycling in russia for a while this past month, and after a certain point on a busy, relatively debris strew road I started hearing a periodic clicking noise that went away if I stopped pedalling hard. Did a quick stop to check but couldn't fine the problem so I kept going but gentler. Then I got a flat. I took the whole tire off the rim and I found multiple steel slivers had penetrated the tire but only 1 made it through the kevlar bead. One of the slivers was huge though (small guitar pick like) and was close to the brake caliper - I guess the extra tire flex was enough to bring it in contact with the caliper when i pedalled.Unknownhttps://www.blogger.com/profile/00403695097675640092noreply@blogger.comtag:blogger.com,1999:blog-13887692.post-53358625378512515302009-08-20T14:03:18.630-04:002009-08-20T14:03:18.630-04:00My guess is you can patch that hole up with some m...My guess is you can patch that hole up with some molten plastic and let it cool.
