Bought this cassette in anticipation of some sustained climbs. Normally have a 11-25 Dura Ace cassette but saved some money by going with Ultegra. Only a few grams heavier but offered the 28 cog to get me easily up the steep pitches. Shifted fine as you would expect.

I was suffering on the uphills against my friends that had a compact set at the front chainrings.

I upgraded from a 25 to this cassette which made a difference for the uphill parts of the terrain.
Also, the 11 is nice when going downhill.

Good compromise overall.

I bought this to replace my SRAM red cog after using a chain for too long and wearing it out. The weight difference is negligible and it actually shifts better IMO. I used to think all te components needed to be the lightest, but man it's expensive to think that way!! You can't beat the price either, locally in Miami thiis sells for $110 and the SRAM for $230 so this was a natural choice for me. Buy this instead of SRAM red or dura ace. Oh and a
Amazon is the bomb!
