Includes the following: 13 tooth #1 cog. 1mm cassette spacer
Spare rear hub dustcap.
Note that this hub is a 6-speed unit, but in a 15 minute
operation it can be fitted with a any current Shimano 7, 8
or 9 cassette freehub. The axle (a $3 part) can also be
replaced and left-side spacers added to for mountain bikes
or hybrids (130-135mm rear stay spacing).
I will also include at no charge either a 7 speed or an 8/9
speed Shimano Hyperglide cassette freehub for the
conversion. Buyers choice. 8 and 9 speed freehubs are the
same. The freehubs are lightly used and have been flushed
out with solvent and then lubricated. 100% functional. I
will also include at no charge the wider rear axle if you
are going to use this hub on a hybrid or a mountain bike.
