Just bought my first Carbon bike

heard stories of peoples frames cracking due to bottle cage bolts ...

Anyone know a good grease to use ? Any tips on avoiding anything bad happening ?

Elite cages on a boardman carbon ... anyone had any issues ?

Thanks :D:lol::D

    Just get stainless bolts and do not over tighten.

    Crappy alloy ones get stuck fast.

    Never heard of that before as long as you dont overtighten them (as with any bolt) you should be fine.

    I changed mine to these in black, blend in better with the black bottle cage and frame for me;

    Coloured ones are even worse for sticking fast than the plain alloy ones. Make sure you put copper slip on them.

    What size are the bolts for our bikes ?

    Thanks mate.

    My carbon bike has nice black nylon 66 ones in, very very light, perfect for the job!

    I made titanium bottle cage bolts which are on all my other bikes, they rock! :D

    Stainless bolts and aluminium are actually very bad. Galvanic corrosion caused by the two dissimilar metals can cause corrosion of the aluminium and sieze the bolt.

    There are some stainless bolts that are availbale that have a special coating to prevent corrosion.

    On carbon cages - I broke one a couple of weeks ago when my bottle did not quite slide back in right. Expensive drink!

    Never had any problems on my TC, the lugs are good, just use a washer on the bolts.

    The Boardman carbon cages are to die for. Beautifully made carbon fibre and only 28g each. They are sub £40 and come with good bolts and washers.

    Those Boardman cages look suspiciously like the Blackburn ones (which are indeed excellent).

    You can get them in gloss and others colours as well.

    The Boardman one is a bit more slender but they are not too dissimilar.

    My current ones are over 3 years old and still perfect.

    Galvanic corrosion could be relevant. Personally I suspect that even on an alu frame the threads for things like bottle cages are probably steel (but I'm going on guesswork not knowledge so anyone who knows please chip in), as a result Alu bolts are probably a bad idea as you'll have alloy on steel at a junction which you very rarely maintain.

    I'd use normal steel bolts or if you want to really weight weenie it nylon. No idea if nylon ones can take the stresses though.

    Apologies, I read the title but did not fully digest the content! I thought it was about securing carbon bottle cages to any frame (bulk of which are alu).

    I thought the bottle cage inserts in my frames were alloy.

    Got some stainless bolts today copper slipped them up and they are working a treat.

    Need to get some washers yet but i'm not sure how much they will do

    Thanks for all the input ! :)
