Btw, if you ever decide to remove that cassette either to clean the cogs or repplace a drive side spok you can remove the cassette with ONE chainwhip. Put the bike into a large rear sprocket. Hold the crankarm firmly and use the chainwhip on the smallest cog to turn it counter clockwise. the chain on the large cog acts as a second chain whip. Once the smallest cog is loosened you can take the wheel off to finish removing that cog and then the rest of the cassette. Be careful not to lose the thin spacer that's often between and loose cogs and the riveted together cluster of cogs. I usually just use a strap to fasten the crankarm along a chainstay.

I like Uniglide cassettes because they are so easy to remove if on tour and I break a spoke.
