View Full Version : Different left/right stays?

Hey all -
I didn't find much when searching. My question is about using different stays for the left and right side seat stays. I'm planning on using heavier left stays and a gusset to counter disk brake forces (on a custom TIG'd steel trials bike). So...I'm wondering if my rear triangle will end up offset after welding. Ie if the two sides were to deflect the same amount inward post-weld, and the left side was significantly stiffer, it'd deflect the drive-side outward more when I stick the hub in, offsetting the whole shebang. Any experience or advice for countering this?
Thanks!

T&T

PS
I have an adjustable skewer (anywheres from 110 to 150mm) on my jig, so offset would be pretty easy to do.

I'm not sure which stay would suck in more. I'd set the rear spacing to 10mm or so larger than the rear hub, then after brazing in the stays, some builders use a torch to warm the outside surface of the stays to offset the shrinkage and reduce the inter stress.

Thanks mang.

When it comes down to it, I guess I'm not too concerned with perfect alignment since it's a trials bike.
