when i kitted my first bike i changed the springs following a suggestion of 3 turns in and thought i clarified it was 360 degree turns. i realize now that was wrong, but the bike ran fine, good in fact for 16/40 gearing off the line, so i never went back and changed them. now i need shoes. will grab some claws when they are back in stock. sourced another e50 2 shoe to hold me over
