before we can do the good work we need the right tooling, and most of the time it means we have to make it… this is a new mandrel for the popular 31.6 seat post… it goes in while i weld the seat tube to keep the tube round and true, and not ovalize… its also good for displacing oxygen which, much like when we purge with argon, which makes for a stronger, more long lasting welded joint… Kelly® Bike Company
