Good Morning,

I am in the process of purchasing parts to build an extruded aluminum frame jig and am having a difficult time finding options for cones for the headtube, bottom bracket and top of seat tube.

I see that Chopsource sells a set of 5 stainless cones with max OD of 2" and minimum OD of 7/8" for $164, so these may work, however would like to have other options such as finding three that are stepped so the BB and bottom of the HT fit to hold them in place a bit better.

I do not have access to a lathe or other tools to make my own, so would prefer to purchase them.

If anyone knows of a better place where I can find these or if you have other suggestions I would appreciate it!

Thanks for your help, especially this being my first post.

Cheers!
JD
