fellow freewheelers... i have decided to purge my regina oro cog collection. i will systematically list them for sale over the next several days. at this time i am offering the following cogs that are designated as position '3'. they will fit the top two spaces on both five and six speed regina freewheels that are 70s/early 80s oro and grand sport types. today, i am listing cogs with these teeth: 27t 28t 29t 30t 31t i have a good supply of each size. the price per cog is $12. first come, first served. please contact me off list if you are interesting. i mean 'interested'. remember, you don't have to use these to restore that old freewheel... they'd look good on a necklace, too. after all, accessorizing is EVERYTHING! e-RICHIE in chesta'
