Hi,

does anyone use nylon bolts to hold bottle cages? Are these bolts strong enough for that kind of application (I use large bottles)?

Thanks!

No issues whatsoever, I've been using them for a year on my two bikes mtb and road with 750ml water bottles.

They came with my Santa Cruz mtb......and 3 out of the 4 broke.
The 2.7 g you save is not worth it. Cage rattling around on a ride and possibly messing up the frame. PITA

Hmm... Two comments, but two diametrically opposite opinions :S Maybe it depends on how are you pull/push the bottles from/into the cages? Gregorio, is it 2.7g weight saving compared to Ti bolts?

I like them but you need to be careful installing them. I even have hade a mini pump mount attached for about a year without issue. I do consider them a one time use however. If your going to change cages often go with something else.

What would be the recommended torque for these? Too low to use a torque wrench at all?

I used to sell them, but I stopped. Not recommended for continuous use. Great for filling un-used bottle mount holes though.
Really for the couple of grams I'd go Al, plus you can get pretty colours too :wink:

I was just saying ....a couple of grams is not enough savings to bother with for the hastle.

Ok just weighed my nylon bolt. .4 g
Alloy bolt is 1.4g from speedplay Nanogram cages
Carbon bolt from my Time is 1.1g
Some other alloy bolt was 2.4g
Steel was 3.7g

When in doubt always go with carbon :wink:

I haven't used them and had always thought of them as good for filling blank holes only. I'd be interested to give some a try and test them out but for the saving of a gram or two I'll stick with Al.

****I've used nylon bolts for bottle cages before and they held up ok for awhile with careful installation. Unfortunately, I have also had a bad experience with them on a super hot day on bumpy chip/seal roads - one bolt broke off at the head and not much further down the road the second one broke taking my bottle/cage with it. The cage and bottle rolled off into a field at 25 mph while I was in a pace line. This all happened about 5 seconds *after* realizing just how thirsty I was and just before going to reach for it... My other bottle was already empty.. :cry:

It took me a while to get the remaining parts of the bolts out of the frame, and my replacement bolts ended up being made of Ti. I took the weight penalty hit of about 3 grams for both bolts and have been much happier, and better hydrated since the nylon bolt failure issue I had earlier.. :smartass:
