Best value for an 11 speed cassette. 1/3 the price for Dura ace and stronger.

I bought this new 6800 11-speed cassette to put on my spare race wheels. I use Dura-Ace on my race bike but couldn't justify the much more expensive DA cassette on a backup wheel. It's fine for the purpose!

This cassette keeps being the best value, for a small weight penalty you get longer lifespan, and is hard to tell any performance difference compared to a Dura Ace cassette for half the price.

Ultegra cassettes work great with both SRAM and Shimano setups. Highly recommend the lower price cassette.
Can hardly wait for this one to arrive from PBK! Ordered Dec 1st and still waiting…

This is typical excellent quality Shimano Ultegra and PBK pricing. I use 11 speed 9000 mechanical Dura Ace on my race bike which is a Trek 2013 Madone 7.9
That set up is incredibly light. Race wheels still get the Dura Ace cassette, but the Ultegra Cassette is just as good in every way except for a small difference in weight. Ultegra for training days, Dura Ace for race day wheels seems to be the perfect balance.
