Hey guys,

Currently working on converting my single speed to a fixed without shelling out the money for a flip-flop, though I know this would be easiest. I'm having an issue with getting a lock ring to fit the single speed hub. I have searched high and low online for solutions, sizing and info without yield. Does anyone know a way to solve this issue? Best description is:

Single speed hub
Removed single speed cassette
Replaced with 16 tooth cog
Everything goes on securely there
Two different lock rings, neither will thread the hub
Hub is too wide for Lock rings to fit: 1) All city 1.29" x 24 tpi left-hand thread 2)Avenir lock ring, same size
Hub set up: SE 36H Hubs w/ High-Profile Double-Wall Rims
Is there a specific size that would work?
Am I better off just putting together the money for a flip flop set up?
