tube sizes
Hi Everyone,

Does anyone know the typical dia. and wall thickness of a central boom tube on a recumbent. Not sure if it changes if the tube is bent or straight.

You might try this link it has dia. and thickness info at the end of the page.

That's a pretty vague question. My V-Rex is 1.5 x 0.035" in chromo. My Baron is 60mm x... more, in aluminum (7005?)

My Tailwind's main tube, not a boom, is 1.5" diameter Chromo. Newer Tailwinds have 2.0" diameter tubes. Don't know about wall thickness. Tailwinds are not monotube bikes.

Sometimes, a vague questions results in answers not anticipated and leads to new questions :>) .035 is a very typical wall thickness for straight gauge crmo on diamond frames. Seems like the larger diameter 1.5" could use a thinner wall than .035. Thank you for your reply.
