This the equivalent of a winch for a bike!

I use this with a Wolf Tooth extension to provide me with an extreme climbing gear when I'm in the mountains, close to the end of a long day and down on watts.

Typical shimano product

Top quality Shimano cassette, this cassette is about an ounce lighter than a sram one for the same gear range and shifts a bit smoother on my one by cross bike. The extra low end is a plus on some of the steeper cross crusade courses like ninkrossie.

A few extra teeth allows for a spin instead of grind.

This cassette fits on medium cage rear derailleurs. The gear spread is perfect so you are able to adapt your gearing to cadence when climbing.

Crush the steepest climbs.

This is a great addition to the Shimano cassette lineup. Not only does it give you some lower gearing for steep climbs it is compatible with 1011 speed mountain freehubs as well as 10 speed road wheels. This has allowed me to use my mountain bike wheels with Ultegra 11 speed drivetrain.

Nice cassette, fits 10 speed freehubs

I bought this to give me a little more gear on the 20% climbs in my area. I had been using an 1132 on my Ultegra 6850 equipped Roubaix. It did what I wanted, with the added benefit that it fits my old 10 speed wheels. The carrier for the largest gears is concave so it will fit the slightly shorter 10 speed freehub body. You need to use a spacer for 11 speed hubs. On the down side, it's 45 grams heavier than the 1132. It works fine with the medium cage Ultegra derailleur.
