After a small scrap on my carbon bike chain stay after a chain dropped....looking at chain catchers

Anyone with experience with Rotor, K-Edge or Token?
Have 50/34 campy set-up

Are the bolts long enough are they easy to mount and test?

See all the pros have them now......looking at Giro bikes

    Do you have a braze on or band fitment front mech. All the chain catchers seem to be for braze on.

    I use the K-edge, it comes with 3 lengths of bolt to ensure that you can fit it without faff, (Braze On only) had no cause to test it but I think thats the best way. Looks good and seems very secure once fitted. Have serviced a friends Scott that has a Deda dog fang and did not find it clamped very secure very easily, but have no personal experience of it at work.

    The Deda dog fang isn't suitable for all frames i.e. you need regular round tubes. I have a Token on my CX frame which works fine. K-edge is over-priced for what it is.
    Make mine an Italian, with Campagnolo on the side..

    I've used K-edge, token and Rotor. All fine, although I smapped a token. There are cheap version on ebay too - see user bi_king

    Set your front mech so there is a slight rub in bottom gear.

    Then you will not need one unless riding Roubaix. Apart from marketing the only time you may need one is using oval rings and rough territory.

    Really if you set the bike up properly you never need one

    so what do you do if you've got a band fitment and don't want chain rub?

    I've had a Token one fitted for 12 months or more and it has worked flawlessly (in that I have not dropped a chain since!). I believe my front mech limiter screws are set perfectly, but you cannot rule out a dropped chain completely due to british road suffices etc, and it seems easier to achieve with compact chainsets. Setting the front mech to deliberately rub is the daftest thing I've heard in a while!

    Either use a Dog Fang if your seat tube is appropriatly shaped (I had to alter my Dog Fang on my Look as the BB lug got in the way), change your mech to a braze on sort with a band on adaptor or find one of the catchers that have their own band mount. Can't remember who makes those but they are pricey irrc.

    I have the Token on my Ribble and it's fine. Can't see a reason to spend up to three times as much for one of the other brands. The Dog Fang has been fine as well. Both bikes have Campag compact.

    even with a perfect setup you can still drop a chain. Every bike should have one. They weigh nowt, cost nowt and can save a whole load of potential hassle/damage. No brainer, as our yank cousins might well say.

    Rub in the bottom gear is to remind you that you're being a pussy and get back on the 17 where you belong

    They’re not uncommon on pro’s bikes (and not just during Paris - Roubaix).

    I guess the pro teams must employ incompetent mechanics who can’t set up a front mech properly. :lol:

    Brought a red Rotor chain catcher from Cycle Surgery in London for £20, works fine. Tested 1st time today with Campy groupset.

    ok your chain shouldn't come off, but when it does. Say goodbye to your nice looking paint job on your carbon bike! or chain stay! my test was manual and worked fine.

    Was told either K-edge or Rotor....forget the rest. they both use high grade T5 7076 aluminium

    Lol! Oh well then, I'd best be binning my Token because it isn't T5 7076. No wonder everyone keeps laughing at me :lol:

    Is all your advise based on bikeshop bollox? :wink:

    Agreed that they should not really be needed on the road with a well set-up drivetrain, but battering your way across a muddy field in a CX race means you do all sorts of horrible, forced gear shifts with a drivetrain coated in mud - dropping a chain can be the difference between 10th and 20th

    How strong do they need to be?? The chain only gives it a glancing blow as it passes by!

    I've just had one of these delivered

    Colour isn't as bad as I thought and it's half the price of the K-Edge equivalent

    I have similar/same as Petemadoc:

    http://www.ebay.co.uk/itm/34-9mm-CNC-Ch ... 2eb634da67

    It took about 2 weeks to arrive from china but is an unobtrusive piece of kit that gives me piece of mind when chaning gear. It is well engineered and has a little allen bolt for fine adjustment of the gap between it and the chain which is a nice touch.

    I am sure that I had my gears set up properly but once every couple of months I would drop my chain. I initially bought a dog fang but couldnt get it to sit properly because of the flared seat tube tube and I couldn't do the ziptie trick as the gap between my chainrings and seat tube was too great and I wasn't willing to pay nearly £40 either so this was a good compromise.

    Canyon do one that attaches to bottle cage bolts which is useful if you have a non-round seat tube / unable to attach to front mech

    You're correct, that is a very dumb question :lol:

    just get one that'll fit your front mech mount, there're a few variations

    Thanks guys- I couldn't think of a reason they'd be drivetrain specific but eBay had some that said Campagnolo specific?

    Anyway, cheers...off to the Bay now......

    Recently bought this, seems to work okay. Simply clamps around the down tube below the front mech.
