HMN420 Guide Nut
HMN420 Guide nut for Sturmey Archer hub with 13/32" axle.
This is the replacement guide nut for hub gear equipped Bromptons.
This is the shorter version which protrude slightly less than the factory equipped long version. No difference in functionality versus the longer version originally equipped on Bromptons.
This version is chrome plated, which is more corrosion resistant.
