Enough for the hills

Normally run a 27 tooth with medium cage rear mech (Ultegra). I was able to to change to the 30 tooth without having to get a longer chain or different derailleur (after asking a bike mechanic) which a 32 tooth would have required. So my trip to Peak District, I was able to do the challenging climbs. So if you want to tackle those 20%ers without too much too much effort, then this is a good compromise.

Good piece of kit

Excellent component noticeable weight difference. Easy to fit and great performance. Clean crisp gear changes ensuring a great ride.

A Proper Bargin

So much better than the Dura Ace cassette it's funny, and at this price I brought 3.

OK But

Cassette is working fine as you'd expect BUT I discovered when I tried to fit it to the free hub that it needed a 1mm spacer behind the cassette to allow the lockring to tighten. Fortunately 5mins of rummaging turned one up in a box of bits. This was a Shimano compatible free hub on a new Campagnolo Neutron Ultra wheel so there may be a specific problem here. I don't use Shimano often but seem to remember that 1mm spacers used to come with the cassettes. Shimano 11 and Campag 11 are interchangeable between both gear systems which is very good to know!

ult cassette

nearly always use ultegra cassettes when i need a new one. great quality at a decent price. works really well with the dura ace chain i purchased at the same time. highly recommended. good delivery and excellent service from PBK.

Junior gear

Excellent to found the neccessary gear for our juniors cyclist

Cassette review

Very Smooth, easy to setup indexing with a slight weight penalty over the dura-ace.

Too easy

If you ride a uphill to faster another one, You installed 11-32T.


I like it very much. It's easier and less demanding when you go up the hill. I will recommend

Shimano quality as per usual

After struggling with hill climbing and refusing to capitulate to a compact crank, I've settled for a new cassette. Hopefully my knees will thank me. Smooth shifting, but what else would you expect? PBK offered the most competitive price compared to other online sites at the time of purchase & fast shipping.
