What more can you write about this cassette! Top quality item at a very good price, says it all really
Just the job. No complaints whatsoever. Thanks. great
Very good price, easy shipping. The perfect cassette for performance.
Great cassettes. Usual shifting excellence from Shimano & PBK had the best price.
Really good service for the ultegra cassette quick delivery and the best price around
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.
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!
This is a great cassette changes are smooth it is light and great value for money. Bought with even more discount from pbk.
Very good value for the payment and exelent prouduct works the same as its uprated durace cassette, very recomended
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 !
