any of you guys use/try Kaisei tubing? they are/were the old Ishiwata. my next build is a road build and it's gonna be almost all Kaisei. i'll post some material specs/highlights if ya'll are interested. this shit is NICE. i've done a few bikes out of it. if they made MTB sizes I would be seriously swayed to use it on everything. like Tom Kellog said of the old Ishiwata: "it's like little men polished the inside" let me know if you have any Q's. steve.
