Shimano Ultegra 6800 11 Speed
5 / 5
Great cassette
Slightly lighter than the 105 that it replaced. Nicely machined and the applicator was very useful, making the installation very simple. The 11 32 works well in my area suiting the climbs with enough on the smaller cogs to give good speed.

Best price by far... what more could you want?!
Lightweight and reliable.... better than Dura-ace..... probably! Only a bit heavier and ALOT cheaper.... and will probably take longer to wear out!!

Always Ultegra when Dura Ace is too Costy
1 speed Shimano Ultegra 6900 11-28 compact cassette is on all my bikes whilst running Dura Ace as it saves a little on the pocket and not too much difference in weight.

Great Value and quality
Superb delivery of this product, really good quality and I always buy Ultegra. No need to buy dura ace unless you are a pro and looking to shave a few grams off your bike. Easy to fit and off you go.

Did what was expected and an easy upgrade!
Switched out the stock 11-28 cassette (on Cube Agree GTC SL Carbon Compact) to this 11-32 cassette, as I'm relatively new to road biking after years of mountain biking and struggled with the reduced gear range on the climbs. The change had an immediate benefit. I read up beforehand and spotted numerous forum posts about potential issues with the derailleur compatibility with this shift to '32...but cross checked on Shimano's website and as I wasn't using the short cage derailleur (the bike has Ultegra RD-6800GS fitted) the only thing that was needed was a new chain to add length.

Pros & Cons
5 / 5
Thes are marginally heavier than dura ace but less than half the price.
I have moved to shimano 11 on all bikes including my TT bike. The ultegra cassettes are great - I even had one milled to fit an 'old" zip disc. I have 11-23 and 11 -25 set ups with compact on road bikes and 56-44 on my TT. Just buy them.

Super light and slick smooth changing.
I bought one of these for a new set of wheels so that I could easily swap between the two. 11-32 gives me the spinning I need on the hills.

Best price for quality cassette
Great price for this cassette. Use this rather than dura ace which I find too expensive, a bit heavier but works just as well
5 / 5
Great performance to price ratio
Had a few of these through the years and would not look at any other manufacturer other than Shimano. Great quality product and performance for the money, not far off Shimano's top of the range Dura Ace. Trouble free shifting for the life of the product - fantastic!

Good stuff
I was looking for a new cassette for junior racing. Previously had to use miche ones (which were rubbish). Thrilled when I found a genuine ultegra one in a 14-28. Mantle are the only place I found it within the UK. Speedy delivery and great service.
Pros & Cons
5 / 5
Cost Effective All Rounder
If one desires dependability with regularity, then the most obvious choice is Shimano's Ultegra 11speed components. Entirely practical without egregious cost, one would be silly to ignore the benefits of running Ultegra, in this case their most excellent 11-23. A cassette that, when paired with either a 36 oor 39 inner will get you up any hill, contrary to what "experts" may profess. The added benefit with this ratio is that from 11-19, there are no gaps, just one tooth difference. A boon when on the local chaingang
Pros & Cons
5 / 5
great item, great service
The 11 speed ultegra cassette is what it is, high quality as always from Shimano. My first time shopping here but will definitely be back - great price, great service and quick delivery.

Ultegra cassette
I really rate the Ultegra cassette for it's crisp changing and very light. More cost affective for me on my budget without too much performance difference compared with dura ace.
Pros & Cons
5 / 5
Smooth shifting at a reasonable price.
Shifts as smooth as the DA but is harder wearing and a fraction of the cost with only a small weight penalty.

What it says on the tin
Great quality backed up by great sevice, I'll be back for another when it wears out
5 / 5
A brilliant compromise for me.
I have two bikes, one is fitted with Shimano 105 and the other is fitted with Shimano Dura Ace. I fitted this cassette to my spare wheel and can use it in both bikes. The cassette works perfectly with both systems.

Smooth shifting and low gears for the hills.
I bought this cassette for my direct drive turbo muni. I have the same cassette on my summer bike and the 105 version on my winter bike. Both are super smooth to use on the road and have great ratios for climbing the hills.

These Ultegra cassettes are the business - they work as they should, and last well as lomg as you keep them clean and the drivetrain well-lubed.

Great quality with improved climbing
Just made the change to a 11/32 ratio with this cassette which delivers the trusted quality and reliability of Ultegra 6800. The first ride on this set up delivered an improved performance in a regular tough local climb that has 20% gradient in parts. Very pleased with the results.

Very good cassette, I wish it was available in 105
This cassette is ideal for NL. Why would you need bigger sprockets on 100% flat courses? I really like it, perfect cadence all the time. Only drawback is that is expensive, I wish there was a 105 version
Pros & Cons
5 / 5
Fine proportions for riding in flat Groningen.
Ideal for flat country. 11-23 nice mix. Exactly what I expect from it. Unfortunately they are going out of the range in the future.

Best value for money
For on the flat, the 11/23 is the best cassette. Transitions are per tooth only the last 2 skips 1 tooth. Rides super and shifts very smoothly like this. Cassettes last a long time for the amount you pay for them.
