Carbon road bike and speed bumps

Hi, my mate decided to take my carbon framed Trek out for spin - but he decided to go (at speed) onto a slightly gravelled track with quite a few speed bumps without telling me! :( Should I be worried? I have checked the bike over, haven't noticed any cracks so far...

    yes
    and I would check the wheels for broken spokes

    and while your at it - look under the crank for road kill



    ??????


    and by the way you have heard of "Paris Roubaix?

    Ever watched the Paris Roubaix?

    Your bike will be fine!

    Welcome to the forum by the way :D

    Cheers NapoleonD. First carbon bike so being a bit sensitive about it I guess - I am sure everyone was the same on their first one :-)

    BTW, have certainly heard of the Paris Roubaix, but always thought they had special set ups for their bikes unlike bog standard off-the-shelf machines.

    My lugged carbon Bianchi cracked at the junction of the seat tube and top tube when I hit a pot hole. I got a replacement on warranty and the 2nd one cracked in the same place sometime on the cobbles during the Tour of Flanders sportive and was replaced on warranty The 3rd one - well I sold it without building it up and am now riding a Cervelo.

    So, most carbon frames are OK, but it is worth checking over.

    If it won't cope with speed bumps or rough road surfaces it isn't fit to ride anywhere. I'm sure it'll be OK. If it's not, it's faulty.

    Your frame will be fine. Just don't let it get wet :wink:

    It should be no problem. My 2000 Trek 5200 has done the Tour of Flanders sportive and then the Scotton 100 which is 100K with 50% off road, some of which is more suitable for MTBs. I was passing some of these as well so it got some stick. The only damage was a puncture. Good carbon is plenty strong enough.

    I got passed last night by a guy on a shiny new carbon bike. I swear I caught up with him 5 minutes down the road where he had stopped to carry his bike over the cattle grid

    They do, at the end of the Tour during blistering heat, all the pro's bikes look like they were moulded by Dali.

    I swear I have a friend who does this with his Alu Pinarello :roll: . He also wont take it out in the rain and the LBS owner swears its cleaner now than when he sold it straight out of the box :lol:
    Cobbles are all very well but I'd rather be riding towards the South of France

    I with Geoff_SS and NapoleonD. They are bicycles and they had better be able to stand up to the usual, and sometimes unusual, road conditions(carbon, steel, whatever).

    Carbon fibre is actually a form of liquorice, if you are ever lost in the out-back, simply leave your carbon frame in the sun until soft ... and you have a supply of nourishment until help arrives ... :wink:
    .. who said that, internet forum people ?

    A carbon road bike will be fine as long as it's make from diamond rather than graphite or bucky balls.

    What about cracks in your [former] mate, after you'd beaten the censored into him?

    I haven't laughed so hard on a bike forum in all my life. Especially "Carbon fibre is actually a form of liquorice..."


    FWIW - my carbon bike hangs on my living room wall. Too afraid to ride it. Ever.

    It's all new to me...
    I've never heard of this carbon fiver... Is it a new credit card or sumthin'?
