Getting a ti bike from Planet-X. Is it ok to use a carbon cage with it? Planet X bottle carbon cages seem competitively priced and seem to get good comments.

    No, the frame will break! :roll:

    ti bottle cages are more comfortable on a full day ride.

    Well I didn't think it was going to break the frame and I know carbon fibre is a plastic therefore I couldn't see why there would be any problem however no harm in just checking is there?

    I'll ask the second part of the stupid question. Does it matter what the bolts are made of?

    As long as they are not titanium you should be fine- my Zinn book says never use ti bolts on a ti frame as they will gall and seize.

    With steel or aluminium bolts ti-prep/anti sieze is recommended but I just used lithium grease myself and so far so good.

    That maybe so, but carbon ones are more responsive

    Carbon cages can be made laterally stiff yet vertically compliant, an important consideration if you care about your water's comfort as well as performance. Road buzz can disturb water's delicate structure and potentially lessen it's rehydrating properties. I found this to my cost on a recent 200km sportive (using a harsh aluminum cage.)

    :Dblorgs post is excellent :!:

    Yeah, too much road buzz can cause the H20 molecules to separate and you might end up with a gob full of hyrdogen and oxygen :shock:
    What do I ride? Now that's an Enigma!

    Oh, right. Didn't realise you were actually serious...

    On the other hand, having a bottleful of hydrogen and oxygen would surely make the bike lighter.

    Perhaps there's a market for this
    - some sort of vibrating device which splits water (fuel-cell technology)
    - you carry a big tank of water, switch this thing on at the bottom of hills, it separates the water and you float-up the hill with a tank of H2 + 02
    - at the top you open a valve and let the gases out, storm down the descent with your usual weight
    - top-up at a tap at the bottom of the next climb

    Would sell like hot cakes to lardy sportive riders.

    doyler, just to bring a smidge of sense to this thread.
    YES carbon bottle cage is fine for the PX Ti frames (I have the frame, I have a PX carbon cage...its fine!)

    PX carbon bottle cages are very nice, you have a choice of matt or gloss carbon.
    I chose matt, apparently most choos gloss.

    The comment on Ti bolts is interesting. There is a risk of Ti/Ti galling and seizing, but NOT with the bottle mounts on the PX Titanium frames. The bottle threads are inserts (kinda threaded rivets. I am not sure what metal these are made of, but it ain't titanium.
    For bottle mounts you are best off using Alu bolts, though because the threads in the frame are NOT Ti, then you can also use Ti bolts with reckless freedom!

    Glad you decided to get yourselve a sportive, they is good.

    Just looking for a nicer looking carbon front mech band for mine, as stock looks like something from a cycle clearance sale.

    Thanks CHB01. Do the bottle cages come with bolts or do you have to buy these separate as I notice they are sold separately on the site so not sure if that's just for spares.

    I do hope I end up with the sportive however it is looking increasingly unlikely. I will know more come the end of play on Monday. Looking at alternatives as we speak. Still the bottle cages are well regarded so will probably get it no matter what bike I end up with.

    What is a front mech band?

    The frame comes with bolts. They are functional round headed alu bolts. Nothing to look at, but do the job.
    I have nicked the black alu bolts from my sons on-0ne inbred to put on the down tube as they look better (tart).

    The band I am looking at getting is this...

    I have also swapped the seatpost with a carbon SASO one from Ebay. Nothing wrong with the PX alu one, but my son needed a new post and the law of the cycling food chain means that my bike gets the poshest bits!

    How the hell could it NOT be? Though I prefer plastic (cage, that is) on grounds of spoiling the ship for a happorth etc etc.
