Shimano SF-1200 freewheel
Hey...for whatever reason, there are weirdos out there who like to coast.
• for use 1/8" chains
• bronze finish
• sizes, 16, 18 or 20t
• uses wacky two-prong removal tool (Shimano TL-FW40)
It is perfectly safe to install a freewheel on either the fixed or free side on any standard rear track hub!
