Shimano 10 Speed Cassettes

I have many 10 speed cassettes with no home after the 11 speed upgrade. All of which are shimano and have never been worn out. I would say average of 500 miles on them, some less some slightly more. All are cleaned and ready to mount. Shipping will be covered by buyer. $7 for priority mail to usa. Shimano Ultegra 6700 12-30 200 miles $40, Shimano XT M771 11-32 100 miles $40 i have 2 of these. Shimano XT M771 11-34 brand new no box $45. Shimano Tiagra 4600 12-30 500 miles $30, I have 2 of these as well.
