FSA 50T Chain ring bolts ??

[wam68]

Hi
I am gonna change the big chain ring on a bike after having noticed several teeth missing. Having read up on it it seems pretty straight forward ( he hopes ) however all the articles make mention of a special tool, in addition to the allen key, needed to stop the back of the bolts slipping when tightening. I don't have one and as such would rather not buy one if there is another way of preventing this slippage. Do any of the more knowledgeable members on line know if there is another method of tightening without resorting to buying another tool. Any help appreciated as I hope to do it tomorrow. Thanks

Get the correct tool and do the job properly. Quite how you "noticed" missing teeth without feeling anything is a surprise. Surely a quick visual check on a frequent basis (when you come in from a ride) is something we all do? Perhaps wanting to do things without wanting to do them correctly has led to this unfortunate state of affairs.

Use steel allen ones and a screwdriver will do the back side.

Have used screwdrivers or any bit of metal that stops it turning. Even a hacksaw blade. Some bolts are allen key fittings on both sides which eliminates the problem.

The tool is only a few pounds to buy, but as others have said, a screwdriver or suchlike will do.

Are the teeth really missing, or are they the specially shaped ones that help shifting?

Like your the world expert on everyone else's chain rings! Generally it's best to be helpful, amusing or silent.

I just use my big screwdriver on the slot at the back (It's about all I ever use it for as it is too big to fit most screws. )

Na, Tim just noticed it after an Aussie Pursuit. 2 really were missing. Anyhous thanks to some suggestions here got the chain ring swapped this morning without further ado. Have to admit sounds beautiful now
