Nitto Stem Expander Bolt


Framebuilders who make their own stems often have a hard time finding expander bolts, because standard bolts don’t fit. We offer Nitto’s expander bolt as a spare part

An expander wedge is not included. Framebuilders can make their own wedge from the same tubing used for the stem — as shown in this photo by Corey Thompson.
