Shimano’s Ultegra range is race focused, but at a more affordable price than the top-tier Dura-Ace line. The R8000 offers 11 sprockets and is available in a broad range of ratios, so whether it’s a tightly packed 11–25-tooth block for time trialing or a wide ranging 11–32-tooth for conquering even the most epic climbs, there’s something for everyone.

Tough, Lightweight, Durable

Machined from a combination of aluminum and steel, an Ultegra R8000 cassette offers an excellent compromise between weight, durability, and performance. To keep the weight down aluminium is used to rivet the largest three sprockets and a fibre-reinforced composite the next largest two. Tipping the scales at a low of 232 grams for the 11–25T, and a high of 300g for the 14–28T option, regardless of your preferred choice you certainly won’t be weighed down.

But, not only is this cassette lightweight and high performing, it is also durable. Corrosion resistance comes via the nickel-plated steel sprockets, so you can ride without the worry your cassette will disintegrate at the sight of rain.

A Shift In Performance

Aside from weight and durability, the R8000 cassette performs its job well. In fact, there’s virtually an imperceptible difference in performance between it and a higher-spec’d Dura-Ace cassette. Shifting gears is exactly what you’d expect from a component maker as known for precision engineering as Shimano, in one of its top-tier products. It’s quick, smooth, and reliable. Hyperglide technology, the brand’s proprietary system, ensures that even under load you’ll be able to change through the gears.

Good cassette. Expensive these days, but what can you do. I use instead of Dura Aca, because price and basically the same.

Good price & original product

Such a shortage of bike parts at the moment, these guys were one of the only places that had this. Original packaging, arrived quickly, no issues. Fitted to a Specialized Tarmac

New Cassette

Good price, great product, short lead time, what’s not to like? 👍

New replacement cassettes

Need a new Cassette for indoor trainer as run ultegra set up replaced like for like, fast delivery and best price from PBK


Excellent purchase from ProBikekit at a very competitive price. The Ultegra cassette is a quality item, used on Di2 it's so smooth and quick to move up and down the block. Used on the summer bike I aim to get around 3000 before changing.

Usual Ultra quality and great value

I purchased a 14-28 cassette for winter use, it's the usual high quality Ultra cassette but with a very useable gear range for the winter.

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!
