Hopefully this will be a good solution for the added stress Paragon sliding dropout with disc brakes place on the CS.

The CS is a Nova S-bend and to match the taper the brace is a section from a chainstay I mangled a while back (I'm sure we all have one of those).

I mitered the CS as normal, brazed the brace on, cut slots in the brace to match the CS, and then brazed in the dropout.

Has anybody else been thinking about solutions to this problem?

Nice clean look. I like it.

Joel,

Can we really quantify it as a problem?

Between a few of the builders here that use the cantilever design with frequency (Walt, Steve, Dave, me), resulting in hundreds of frames, there have been few if any issues.

Key elements to consider are proper tubing spec at the dropout end, appropriate insertion length, and a proper brazed connection.

One point of consideration is the addition of a stay brace...personally I choose not to use one.

FWIW, a very elegant brazed gusset on your piece, certainly adds to the integrity of the stay.

cheers,

rody

I like the astetic of what you've done.

I think that the problems of the Paragon Sliders is the massive amount of alumium releaved below the brake tabs. I'm starting to think of getting some solid versions and giving them my own swiss cheese treatment.

Very nice!

As I've said before on other forums, I don't feel that it's a problem, but that's an elegant way to reinforce the chainstay.

Very nice! I too though have never had an issue, nor have I seen one personally. I am with rody and walt that if designed and brazed well, I think it is a non-issue.

A+ Rody pegs it on this one. steve.
