Ultegra 6800 cassette

I'm a bit of a Shimano fan (shame on you say all the Campag fans). This is part of the new Ultegra groupset range which is one step down from Dura Ace. The differences between the top end groupset and 6800 are in my opinion miniscule. The cassette is well made, engineered and excellent valu for money. Need I say more.

Shimano ultegra 11 / 28

Hi all, Just a quick note to say that this cassette performs very well, just as I had expected, with shimano quality. I needed a bigger 1st gear so had to swap the old 25 for this, and the results are very pleasing, don't waste your money on dura ace, buy this!

Large gear range

Bought this as i already have two 11-25 cassettes (on different wheelsets). Just got this for 100 mile sportive that was especially hilly. The extra cog on the 11 speed really improves this cassette over the older 10 speed ones as there are less noticeable big jumps between cogs . Still i would much prefer the 11-25 !
