Solid cassette replacement choice

Needed to replace the cassette on my 2017 Cannondale SuperSix Ultegra Disc so I chose this cassette, which was a close equivalent to the original. Shifting is flawless in combination with a new chain and shifter cable.

32t is just that little extra
by GDS PDX

I got a set of climbing specific wheels and wanted a cassette that would leverage that even further. The 32-11 was a good call. I really don't use the 32 that often (most climbs are fine with the 30) but when you hit a wall and need just a little more leverage and a little more confidence, the 32 is nice to have. I was worried about chain length because my other wheelset has a 30-11, but I have had no problem. If I was moving from a 28 to a 32, I'd probably need an extra link or two, but the 30-32 switch has performed fine on an Ultergra Di2 longcage derailleur.

I use it for mountain climbing. Long grades above 10% require me to stand in a 34x28, so this just makes the difference between sitting and standing.

Not much to say about a cassette - other than works well, WBW has great prices and fast service - and Ultegra level has great value.
