Mr Kaye Good all-round performance
Mrs DAVIS Bought this so I have a spare cassette to Zwift online with ease! This is the cheapest price I could find online for this product, and I searched high and low. Great value and the order arrived early.
Jon777 As to be expected with any Shimano product it's well built and performs perfectly. A really great price from Merlin Cycles too!
RC One of the best choices for cassettes. Best bang for the buck.
Jiri Shimano Ultegra is a good line of products for reasonable price that must satisfy every avid cyclist. You don't go wrong with Shimano.
Mr Campbell Perfect triathlon gearing
Steve J Long lasting excellent reliable cassette from Shimano. Great value.
Thomas Purchased 12-25 to replace 11-28 for middle-gear range benefits. Ultegra - highest quality cassette with probably a little more durability than Dura Ace. (Obviously, a little heavier)
Mr Kinney I have ridden and raced Shimano casesettes pretty much exclusively for decades. This is my first experience with Dura Ace 9100 and using an 11 speed casette. The shifting is precise. As I have lost power through aging I found myself craving an 18 tooth for cruising at the most comfortable cadence for long miles. This left me with either 11-32 or 12 -25. Maybe there are options I am not aware of. At any rate the Shimano 6800 proved bang for the bucks right on.
Mr Mäkelä Smooth and solid shifting. Good quality and great value for money.
Mr Owen I can`t tell the difference between this 6800 and R8000, so as the 6800 was discounted.. An easy decision to make. Smooth changing and lightweight enough
Mr Munro Nicer finish than 105, only a tiny bit heavier than Dura Ace but massively cheaper - the sweetspot!
Edwin Really good 11 speed cassette, as it includes a carrier for the largest 3 cogs, and an additional carrier for the next 2 largest cogs. I find this ultegra cassette to be great as it does include all the splines for the freehub mounting, as opposed to the 105 level cassette which does have a carrier for the largest cogs, but only has some of the freehub splines/teeth? which could potentially bite into the freehub interface.
Mike This is a great cassette, only used for a few rides so far but the shifting is fantastic. Fantastic price offered by Merlin.
Christopher 12-25 cassette has good gear spacing for flat and moderately hilly riding. I find that having the 16 tooth gear is great for 39-41km/hr, this gear is missing from the 11-28 cassette and it is a noticeable gap.
David Super finish, light enough, I cannot warrant Dura Ace cost. Wish there was a 12-28 to combo with 39/53. Good service from Merlin as usual.
Jonathan It works but then cassettes always do. Pay more for lighter components. Ultegra is a reasonable balance of cost and weight for the race bike. Lasts as long as any other option.
Ian Exactly what I needed. 11-25 has tighter ratios than the 11-28 cassette I had previously fitted has filled the gap for flatfish time trials and triathlons.
Mr Stretton Direct replacement for a cassette that had done 5000 miles. Works perfectly straight out of the box.
Mr Fitzgerald Timeless classic....only cassette I'll ever need.
Mr Rollinson Just as good as the Dura Ace version only slightly heavier but half the price. Whats not to like
Mr Channing-Turner A great upgrade to my current setup and as with shimano your safe in knowing that quality is assured. If you ride a lot of hills I would go for the 11-28 instead of the 11-25.
Daniel Shifts great and light weight.
Peter Typical fantastic Shimano reliability and quality. I've been using Ultegra cassettes for when I don't need to watch every gram on a build. Ultegra simply works as well as Dura Ace for a fraction of the cost. My order arrived out of the retail packaging - which is great! Who needs to air freight more cardboard across the globe.
GC Great product and brilliant day-to-day training alternative to Dura-Ace. Solid and robust. Great value.
Benjamin Not the sort of cassette you can rewind with a pencil. (Dad joke). Top Ultegra quality, fitted to my wheel off turbo. Great price from Merlin, and very fast delivery.
Chris Taylor Trying to find this item on the internet had proved difficult as few companies had the gear-ratio that I wanted. One final search led me to Merlin Cycles who not only had the item in stock, but at a better price than most, if not all, other competitors; something of a relief all round!! With quality assured in the brand, I placed the order and confirmation was immediate. The Royal Mail tracked package was packaged well by Merlin and arrived within 2 days after the order was placed, well within the guidance on the website. I rate the product and Merlin Cycles as 5-star and have added the site as first port of call for future items I might need.
Ricardo Solid performance. Light, durable, lasts longer than Dura Ace with same performance
Mr Filipek The 11-32 cassette gives me that extra gear needed for climbing big hills. The performance of Ultegra components is without compromise.
Adrien R. Awesome, no faults and as to date have ridden up to 5000 miles since March. Will be changing it soon during my full service before winter time :) Bought this along side the Shimano Ultegra XT CN-HG701 Chain.
Stephen Top of the line in terms of performance and longevity from Shimano - not as light as Dura Ace but lasts longer.
Kevin Nice to have a 32 for the mountains. Shimano delivers again.
Scott. 11-32 cassette works well on the 2003 era steel frame I put it on. Changes are fast and crisp. Hard to differentiate between what impact the RD has and what the cassette design has. All good!
Munro Last about 3 chains over the winter and 2 seasons when used in the "summer" - works and cleans up nicely.
Ed Ng It's an Ultegra cassette. Nice and lightweight and well-made, smooth shifting to boot. What would one expect?
Danilo Upgraded for my current Shimano 105 cassette to a Di2 and I have to say it's worth every penny. Shifting is flawless and quick. I would definitely recommend this to anyone who ask.
Ms Ferguson Can`t go wrong with Shimano Ultegra - I prefer these to their Dura Ace as the quality is just as good and they are half the price. Ran this cassette on the weekend for 2.6km of climbing and it was faultless!
Mr Smith Replacement spare for what is a fantastic bit of kit. I do a lot of miles and it has never skipped a beat.
Mr Gregory The Ultregra 6800 gear is good stuff. Smooth and accurate gear changes and a cheaper alternative to Dura Ace. Once again Merlin delivered within 7 days to Australia.
Mr Slomp Very nice close ratio cassette, perfect crisp changes every time
Mr Burton Good shimano quality and decent durability provided you keep the chain clean. I do tend to find the lockrings aren't as good as other cassettes
HT Great ratio cassette for when you live in very hilly areas. Smooth as you'd expect from the Ultegra range and not too expensive, given how far up the options of model it is.
Bryan The workhorse cassette. Far cheaper than dura-ace, but exactly the same level of performance. I had the Dura-Ace on my race wheels last season, but couldn't justify the price again. Ultegra all the way.
Munro Just works - smooth changes and lasts well. Cleans up really nicely due to better quality finish/materials than 105 equivelent.
Bob Kirkwood More durable than Dura-Ace. Works just as well. No point in buying Dura-Ace considering the price difference.
Mr hutt I decided I wanted a good quality cassette but didn't want top top end but better than standard. I always review before I buy and these are the best value for money. Smooth and precise gear shifts so really impressed. For great value, Merlin are unbeatable.
trahan Well built, reliable with quick clean shifts
ferrara The only problem of Dura Ace is...Ultegra. Sure a bit heavier but it last almost the same and it has the usual Shimano high quality.
Mr AYAZ I replaced my old 105 cassette with this set...I bought 11/28 combination and good for climbing...Light and strong...Classic..
Naccarella All the gears and quality you need. Lot cheaper then Dura Ace can't notice the difference on my bike to be honest.
Mr EKİCİ This casette have a low chain resistant and easily gear changing. More rigid then older model only added 20 gr. Good choose, recommended that.
Minier Light weight and durable good for road or 'cross.
Saylor Shimano Ultegra. It's the standard to which all other components are measured.
Mr Gatward I needed help for climbing those impossibly steep hills so decided to replace the 11-28 with the 11-32 cassette. My first ride on it was in the Peak District and I was so glad of the bigger ring towards the end of the ride. Worked faultlessly with the medium cage derailleur. My LBS fitted was prepared to fit it for me as he could not match Merlin prices.
ferrara I have Durace 9000 on my bike, but I decided to use the Durace cassette only on my racing wheel, while I wanted to try the Ultegra one on my training one, since it saves me 100$! It works perfectly and it weights only 60g more.
Mr Bowen Arrived promptly and in good order. I installed it, replacing a 11-25 cassette. What a difference the 28 tooth cog makes on steep hills.
Jenkins Great performance and a weight saving over 105. I think they are worth the bit extra and last well if looked after.
Hitz I love the 6800 series. It offers all the technological benefits of the DA9000 stuff without the exotic, and expensive, materials. Life is fantastic and performance is great.
Kim More durable than Dura-Ace cassette. I wish there was 12-28 like the Dura-Ace though.
California rider Great quality silky smooth shifting, basically dura-ace quality without the dura ace price. It's not as light as the dura ace component but operation is flawless on my dura ace di2 setup
Mr McNicholas I have a number of these cassettes and rate them all highly. Easy to fit and delivered quickly. I highly recommend the product and Merlin.
Mr Britten Great Cassette, lasts a lot longer than Dura Ace and the weight penalty is minimal. They also stay bright and shinny compared to the Dura Ace version
Mr Munro Works flawlessly and cleans up nicely due to having a better finish than cassettes lower down in the pecking order.
Mr Zeiders Excellent cassette for the cost. Shifting is smooth and if you didn't look you wouldn't know it wasn't a Dura-Ace
Mr Marsh Smooth and reliable changes, the ultegra cassette is bulletproof.!! Would definitely recommend.
Mr Santos Excellently lightweight, easy to fit, beautifully crafted.
Mr Witthoff I am a big fan of the 32t cassette. The Ultegra Cassette is such a good value. Nothing but positive things to say about this cassette.
Mr Simpson As expected, top quality and smooth changing cassette from Shimano. Excellent service and price from Merlin, too!
Mr Pennington Bought to complete my Dura Ace set up without splashing out on the 9000 cassette and chain. Works brilliantly and only a few grammes difference. Arrived super quick as usual from Merlin. Best price on the Internet. Great service.
Mr graham Nice cassette. Shifts great. It is a little loud though.
Pierre Very good cassette, and Merlin had an excellent price on it. Usually Ultegra cassettes are a good choice over Dura-Ace as they are much cheaper and last longer.
Mr kawashima Very good shifting response and good finish.
Mr jenkins Excellent quality, very good gear changes
Mr Jerham Excellent value for money, light and perfect gear changes every time why buy anything else !!!!
Mr Shane Awesome shifting performance and beautiful machine work on the teeth of the cogs. At Merlin's price, I should have bought several for the future.
Mr Kocher Gorgeous piece of equipment; shifting beats Sram hands down; hard to justify the $$$ for Dura Ace on a consumable part like this.
Paul Goulden Light, cheap, quiet, smooth. Full marks.
Mr Han I went to 11spd, and this was my choice of cassette. Awesome choice! Smooth and quiet paired with my dura ace chain!
Mr Logan I decided to purchase this after struggling with a standard 53/39 crank on long rides with very steep gradients of 15-25%. The 32 cassette allows high cadence with those gradients which is reassuring knowing you can tackle just about anything that crops up on centuary rides. Being 11 speed and going down to an 11 tooth cassette means no sacrifice in speed on the flats or downhill. Highly recommended!
Mr Cushman Fantastic. Do yourself a favor and ditch all your SRAM cassettes and get Ultegra (or if you have the money, Dura Ace). Lighter and better all around.
Mr Newman Changing gear is just as fast and quiet as my Dura Ace 9000 but for a third of the price. Great value
MarkS The 11-32 cassette makes those hills a bit easier but requires the longer Ultegra derailleur. Very pleased though.
Mr Lloyd Great product that works just as well as Dura-Ace without the cost and minor weight imposition
Mr Scott Nice looking, super smooth and not massively heavier than Dura Ace (and in the centre of hub where rotating mass makes little difference) but a LOT cheaper. Excellent.
Grinta23 As with every Shimano component that I have, it works flawlessly.
Mr Hepworth Great product, smooth, quick, precise shifting.
Mr CARVER I've moved up to 11 speed Ultegra from 105. The Ultegra 11 speed shifting is much lighter feeling and very precise. The extra 11th gear does make the ratios a little closer for smother changes. The 11 speed ultegra cassette is also lighter that my 10 speed 105 cassette. Over all excellent.
Mr Puttick I find the Ultegra cassettes last considerably longer than the Dura Ace, are considerably cheaper and work with no noticeable difference. O.K. the Ultegra is heavier but you can always have a smaller cake on a Sunday :-)
Mr Stevens At half the cost of a Dura ace cassette its perfect for your training wheels if you run the 11speed Dura Ace group. Great value and performance as always from the Ultegra range.
