The Shimano 5800 has gone 11 Speed for the latest incarnation of the 105. The 5800 has been inspired by the innovations of the more upper end Shimano Ultegra and Dura Ace; you can see the technological influences across the design of the 5800 components. More advanced and lighter than its predecessors and with a more eye catching design, the 5800 promises high performance and is one of the latest cycling must haves.

Great all around cassette! The best if you ride around hills and do a lot of climbing. This is my second purchase and I highly recommend it. Pair it with a compact chainset and you can still use a short cage rear derailleur. Great price too.
Great cassette, no issues at all!
Great price for a superb performing piece of kit. Not that much heavier than 6800, and smooth shifts make this an absolute bargain!
Bought this for my trainer wheel. Great price, great reliability, no complaints. Very prompt service from Merlin. Will definitely order from them again.
Nearly as good as Ultegra but just a little heavier. Save the Ultegra for racing and run these 105 gears for everything else!
The best cassette for all around riding and climbing. Combined with a compact (50/34) chainring, you can still enjoy the high gear for all out sprints and a low gear for real steep climbs. A must have if you do a lot of climbing.
Usual Shimano quality, I replaced an Ultegra cassette (25-12) and the shifting quality is just as good with this next tier down 105 cassette. I cannot yet comment on the long-term wear qualities but first impressions are good!
Good quality, cheaper cassette. Perfect for use in winter when you don't want to wear out the "Sunday best".
I bought two of these cassettes - they were the best value cassettes that I could find anywhere on the net. I am sold out on 105 cassettes - they are not the lightest that you can get, but extremely durable, and work perfectly with my ultegra and dura ace bikes.
I bought the 11-28 to replace my 11-32 on the stock bike, and have managed the hills to date, and appreciate the closer grouping in mid range.
Works as advertised, and is essential for crazy hills. Barely heavier than the ultegra version (it's on with my ultegra everything else), and comes out of the box so very shiny!
Shifts really nicely, hopefully it will be durable too. I have an 11-28 and the extra cog with 11 speed really makes all the difference over 10 speed 11-28 with the way it ramps up - the gears are more evenly spaced, it's like a 10 speed 11-25 with a 28 added on top
