Seatstay to toptube / seatpost yoke

The top of the seatstays is another place mitres slow a build down and show every small error.

This seatstay to toptube / seatpost yoke is designed around your geometry so the seatstays meet the junction cleanly — whether that lands on the toptube, the seatpost / seat tube area, or your preferred layout. Cut the stays square, socket them in, and TIG weld. Same idea as the chainstay–BB yoke: a regular socket circumference is easier to join than an awkward mitre, and the finished bike looks sharp because the part was made for your angles, not a stock casting.

Print materials: 316L stainless or titanium.
Fit: straight tubes into sockets (other sections on request).
Configurable to your seatstay length, angles, tube diameters and how the junction sits relative to the toptube / seatpost.

Suited to road, gravel and XC frames. Pair it with the chainstay–BB yoke for a full printed-junction rear end, or use it on its own.

Set the geo in the online tools, pull mitre and jig drawings, and order the design files for your build. Printed parts in stainless or titanium available when you want us to make the metal.
