    Kool Stop Brake Pads 4 Sora Tiagra RSX?

    I am trying to upgrade the braking on my Lemond Reno. It has RSX brake calipers s on it. Shimano pads, M50T or A410. (Not cartidge style)

    I purchased some 'Dura Type' holders and pads by Kool Stop but they don't fit. The threaded nut is too big for the slots in the caliper arms. I also have a set of 105 cartridge pads and have a similiar problem using them on the RSX calipers; the bolt receiver on the 105 cartridge is not flush on the back of the cartridge and is too large to fit into the caliper arm slots.

    Preferably I'd like to find cartridge holders to fit (narrow bolt) the caliper arms. Widening (drilling) the slots is not an option for me.

    I would also consider not upgrading to cartridge style pad but I didn't a direct Kool Stop replacement for them.

    Any help is greatly appreciated.

    Why not? I did this conversion on my son's bike with RSX levers and the amount of material I had to file off was very small. Use a small flat file and file on the "trailing" edge of the slot to remove material fron the less stressed part of the arm. That is, file the rear edge of the both brake arms.

    Kool Stop Continental pads. I have to use those because of the narrow slot as well.

    Thanks for the replies. I will attempt to widen the slots, if it becomes a problem I will use the Conti's. Thank you both.

    If you don't want to widen the slots, just file your brake pad posts

    The very best pads I know of for this type of calipers are the Kool Stop BMX/Mountain model. That's what I use, they work great.

    They have a very large contact area, and are curved above and below to match the curvature of the rim. They also have excellent hardware that fits all calipers designed for threaded shoes, and provides angular adjustment via "spherical" washers.

    I used Avid cartridge brake pads

    as well as Clark's road cartridge brake pads and both of them work very well.
