happy with my purchase
Was glad to get hold of this for a replacement item - I search lots of sites, and was only able to find a Ultegra 8000 - This does not fit the 6800 - So Glad to find this at the right price

Reliable front blade from Shimano
Needed to replace my Ultegra FC-6800 blade as the current R8000 is not compatible with the front derailleur. Was glad I could find it here on Mantel. Admittedly more expensive than Amazon and BikeInn but wanted to avoid problems with fake components (Amazon) and three-week delivery times (BikeInn, according to rumor). Mantel's price was 15% more but the product was delivered quickly and works well! Attached picture showing the new blade compared to one that has run 31000km.

I am very satisfied.
Hello, I previously drove with the chainring size 50/34 and find the increase to 52/36 makes itself really noticeable, both in sprinting and at Maxspeed!

Good and cheaper than latest version, but fully compatible
This chainring is not the latest version (Shimano Ultegra R8000), but the predecessor (Shimano Ultegra FC-6800). Technically, both versions are compatible, so you can easily choose the version that is currently available. The hue has changed a little, however, so who puts special emphasis on the look, should look beforehand on the inside of his crank, which version it is on their own wheel.

Great product, great service
These are like for like replacements for existing Shimano Ultegra 6800 chainrings. The original ones had lasted more than 50,000 miles and, whilst there was some life left on the inner ring it made sense to replace both at the same time. Best price and quick service from Mantel

Great piece of quality kit from Shimano, ready for the next 30,000km!
Worn out the old rings, new chainset or replace the rings?...went for rings for funds reasons. Fitted it myself, so chuffed to be able to get out of the saddle again.

I couldn't find any of the other major retailers who had stock of this item who were not ridiculously expensive apart from Mantel. Really easy website to use and delivery was super quick.

Does what it says on the tin!
What to say about this? Bought this to replace one that had worn out after 2 winters and about 5000miles if this performs the same it will be well worth the cost.
