Rated 5 out of 5 by Good upgrade. Got this as an upgrade from a 105 cassette. Shifting is improved slightly and it's a bit lighter than my old 105. I've done over 400 miles on it so far and had no problems. 25 August 2009
Rated 5 out of 5 by great value 07 August 2009
Rated 5 out of 5 by Perfect buy! Do you want a lightweight product and superb value for your money? Do you think Dura Ace is overkill? Buy the Ultegra Cassette. Maybe some more weight but the functionality is perfect! 06 August 2009

Kids who race have restricted gearing with role outs from 5.5m, 6m upward. These are the rules set on us by cycling gov. Bodies.

To achieve 5.5m we are limited to 14T rear, 36T chain ring or 13T, 34T chain ring.
6m needs 14T and 39T chain ring.

Shimano Ultegra 6600 is one of the limited choices.
Why not support kids globally and sell the 14-25T ultegra 10 speed cassette?
They would sell like hot cakes! Must be well priced to compete with wiggle, £30 about. Thank you.
