This XC Comp hollow axle rear hub has 130mm axle spacing and is sold without the quick release skewer. This hub requires the use of a Suntour 7 speed non-microdrive cassette where the smallest cog is a thread on cog AND has 12 or more teeth. We have 8 speed Micro Drive cassettes which will fit this hub, by removing the smallest cog and using 7 gears in non-MicroDrive fashion. The small cog is difficult to remove in this case. You can also use the 6 gears of an 8 speed cassette and a standard bottom bracket lockring to cinch the whole thing. Makes a great compact cassette on hub this way. NEW old stock!
