We have a TIG welder in our shop, so they'll be welded in place. If you don't have access to a welder, basically any motorcycle shop near you will have one and you could work with them for a sponsorship.

Mostly to not over constrain things as stated above. Secondarily to make it so that I don't have to keep track of left and right versions of the tubes since putting a hole in the middle of the tube would cause the tube to interfere with the gear on the rail.
