Ready for the mountains in no time.
Changing the blade is very easy: just loosen a few Torx bolts and the old blade comes off. The new one is back on in no time.
Pros & Cons
4 / 5
Too bad the 46T outer blade does not include mounting bolts.
I wanted to go from 52-36 to 46-36, so I bought a new front blade. Beautiful front blade, but for some reason you can't just screw the 36T to it, for that I had to buy another set of nuts in Germany. Too bad. Otherwise a beautiful blade of course.

This product is just what I was looking for, and I'm going to buy the large tray as soon as it's available.

Top chainring
Shimano ultegra is always good. Mantel again had these in stock the fastest. (Corona perils) Great to get an email then so the coffee grinder could be converted back to a silent drive.

Its a Shimano chainring, enough said!
Exactly what I needed and at a good price. I seem to be getting through outer chain rings rather more frequently than I like. I usually just buy the whole chainset, but this time bought just the worn part which obviously saved me some money. Would also like to point out the excellent and speedy service by Mantel (10 stars for that). I usually buy from a competitor (name beginning with W) but they let me down badly earlier in the year, taking over a month to deliver a new chain. Assuming prices remain comparable, I will be using Mantel going forward.

Great product
Easily fitted chainrings to cranks, once fitted shifting gear was effortless again and the front mech only needed slight adjustment from the 50/34 chainrings which were on previously. Overall I am very pleased with the product.

Light stiff - doesn't fit 6800 slickly
Great rings, love them. Ligt and stiff. Only issue (my fault) I bought to replace a 6800 ring and they don't fit perfectly (lines dont line up) but that's fine.

Good product at great price
I needed to replace my Shimano chain rings and I prefer the 52/36 combination rather than the 50/34. Mantel offers these at prices better than anywhere else. Mantel are my go to internet cycling portal.

Does the job perfectly
I changed my 52/36 compact to a 52/34 and it works perfectly, even though Shimano do not recommend it. The chain may go slightly loose when using the 34 ring and the very smallest cog on the cassette. But I never use that anyway. Perfecto.
