    Is there anywhere to get brake caliper drop bolts?

    I just really like the double pivot brakes that I currently own, nice Shimano RX100 which look identical to 105 brakes. But I need a drop bolt so they will reach my 700c rims.

    I can't find any and I really don't want to resort to home made klunky looking fixes.

    Cheaper/easier to just buy standard reach calipers. Modern ones are available from Shimano, Tektro, and others.

    If you are able to find a drop-bolt that works for your caliper, go for it! However, those were only popular with the old-style single-pivot calipers. I've found making these brackets work really well for modern dual-pivot brakes. Thanks Sheldon!

    NB: those are for single pivot calipers, the groove is to carry the return spring.
    a replica of the older part, when Campag single pivots were tops.

    as OP was asking to retain their dual pivot brake , that piece[in#3]
    does not help.

    So, shopping for a longer reach caliper, in reality, will be tidier ..

    Wow, those drop bolts are beautiful but damn, 150 dollars for a pair? Really nice machining.

    Now what makes those usable with only single pivot? I'm just wondering.

    I'm going to be shopping for longer reach brakes now.

    wow, shoulda stocked up on drop bolts back when you could get them for $10. Although they wouldn't work for a dual pivot brake

    Ahh, I figured it out. Dual pivot brakes have the bolts going the other way because of the pivots. Obvious when you look at one up close.

    Single pivot brakes..Symmetrical return spring goes thru that slot
    to a stop on each brake arm, where it opens up the brakes.

    I had the same issue and came up with this. There are no guarantees that it will work, especially on the front. I used it on the back brake for a while and it worked fine. It's made from a cable ferrule.new2.jpg

    Sorry, but looking at those homebrewed "solutions", I look at them and ask myself "Would I trust my life to that approach?"

    In all of those cases except for an actual purpose-made drop bolt, the answer is "no".

    Just buy new calipers and be done. Saving a few bucks won't matter when you're dead because you grabbed a handful of brake in an emergency and they failed. Even filing the bottom of the pad slot would be safer than any of those approaches.
