    Blizzard derailleur hanger question

    I have a 2004 blizzard frame that I built up using parts from another hardtail, this is my first steel frame.

    My question is; are you supposed to use a breakaway derailleur bolt on these frames since the derailleur bolts directly to the frame?

    In simple words, NO.

    The steel derailleur hangers are much stronger than the aluminum ones. Aluminum ones NEED to break or bend before the frame they protect does. If you bend a derailleur hanger on a steel frame bike, just take the derailleur off and bend it back straight with a cresent wrench.

    better a fragged bolt than a mangled derailleur

    There is still some advantage in using an aluminium pivot bolt for the rear derailleur, if you do catch it on something it's generally cheaper to replace the bolt rather than a pricey derailleur. Not that it makes it any easier to get home again with the derailleur ripped off versus having it mangled.

    Err, well, you are right that there is no need for the break-away hangers, as on Al. frames, but, you should have a shop put a proper derailleur hanger adjustment gauge on the frame (Park makes 'em) and be sure that the hanger is true. Even if the hanger is out by a few degrees, it is almost impossible to get the rear derailleur to perform as it should, no matter how much you tweak the set screws. Just my $0.02!

    I heard of fix once

    A friend of mine years ago would take his derailer off and cut 1/4 to 1/2 of the way through the main bolt so it would break well before the frame could get damaged. I have never done this my self but I have never had a steel frame.

    I decided to use an aluminum bolt to avoid any potential problems. It was cheap enough.
