This is a Harris Cyclery exclusive, designed by Sheldon Brown, based on a Shimano CS-6500 Ultegra cassette.
This is intended to provide nice low gears and still preserve reasonably close spacing in the cruising range, without wasting gears by devoting space to ludicrously high gears. This is intended to be a good match for bikes with traditional "full sized" chainrings.
It is generally good practice to replace the chain when you replace the cassette.
We recommend the SRAM PC-951 chain for use with this cassette.
This cassette will index with any Shimano-type 9-speed shifter, but does require a wide-range (touring/mountain) rear derailer.
This cassette will fit any Shimano 8/9/10-speed hub.

I just put this cassette on my Koga Globe Traveller. I have also changed the crank to a 22, 32, 42 XT. On a heavy touring bike the stock higher gearing was unusable. I still very rarely use the highest chainring. I find with this cassette the jumps do not cause pain in my knees when shifting up one gear. Having close ratios is important. I wish I had experienced how much nicer it is to have 14, 15, 17, 19 steps on the rear. I can now keep my cadence in a comfortable range, without feeling I am spinning in too low a gear or shouldering into too tall a gear. Just because you are not riding a road racer does not change how much better close ratios are. Having close ratio, lower gearing has been an enormous improvement. Harris is so far ahead of the industry on this overlooked design element.
Over the last 5 years I cycled over 60.000 miles, visiting 50 countries and carrying everything needed for a long trip including a tent and winterproof sleeping bag (see www.jkoelstra.nl for maps and pictures). On average the cogs are getting worn out after some 7000 miles when not changing the chain or after some 10000 miles when changing chain each 2500 miles.I don't want any other cassette any more (unless it would start with a 15 or even a 16 teeth cog)The pro's: = No highspeed gears that I will never use on my heavy loaded bicycle = Steps between the gears are small all the way up to the lightest mountain gear
when touring fully loaded i am never in my high gear ratio so this allows much closer shifting and i get to use more of the gears that are available to me. it just makes sense
