Reviews over the

Shimano Dura Ace R9100

I have always used original Shimano Durace parts the Toop of the range My policy has always been that the more you spend the less you spend

Pros & Cons

From Japanese quality you are always sure it will work well. Haven't mounted it yet (waiting for 53X39 front blades to be available). That it will work well is already a certainty.

Pros & Cons

Everything perfect the type of article and its shipment in the indicated time.

Pros & Cons

Dura ace cassette, quality, durability and very wide range of sprockets

Pros & Cons

Durace the top is the second sprocket I change excellent quality best to replace the chain early x make it last

Pros & Cons

The parcel was delivered very quickly, great site

Pros & Cons

Shimano Dura Ace for me the best

Pros & Cons

Product arrived in a few days. Excellent packaging. Everything ok

Unbeatable value for money.

The top of the range from shimano pays off not only in terms of lightness, but also in terms of robustness.

Pros & Cons

11-30 is a good all rounder for me paired with a compact chainset. Dura-ace looks and feels top end and when paired with dura ace chain provides near silent chain running- a marked improvement on the ultegra cassette and chain Combination I had previously paired with dura ace Chainset and derailleurs. It costs more but ultimately is worth it if you value the silence!!

Pros & Cons

Pros & Cons

The perfect compromise with the 52x36. A wise purchase

Shifts perfectly, should do for that price.

The most competitive prices plus good delivery service make Mantel an easy decision when buying.

Pros & Cons

Versatile development range with reduced weight.

Pros & Cons

Bought a new Dura Ace Shimano cassette and it arrived with great speed and the quality was excellent. I thoroughly recommend this product as replacing it has made my bike feel like new again. Very durable and light.

It's a real treat, the speed of the sprockets, the smoothness and all in silence, it's not cheap, but it's the best!

Pros & Cons

Replaced the previous DuraAce cassette after 19,000 miles approx. Always works well, light weight and reliable.

Pros & Cons

Good price, excellent delivery and easy to purchase. I'll be back

This item has been purchased as part of an upgrade ad is not fitted as yet. I have an 11-28 R9000 cassette which has been exceptional and hope the R9100 cassette will prove to be at least as good.

Pros & Cons

Better gear ratio for climbing. Best price from Mantel.

Dura-Ace quality and looks give a bike that little something extra and the addition of this 30 tooth climbing cassette in the range adds a whole new dimension for amateur riders. Mantel's service, communications and the best price by a mile impressed me as did the fact that that they are obviously as mad about bikes as I am!

Pros & Cons

Shimano has excelled itself with this latest version of Dura-ace, even lighter than before. Cassettes do not get better than this, but you pay £££ for it!

Pros & Cons

Works with Dura Ace 9070 ( first gen 11 speed dura ace) rear derailleur , smooth shifting, looks amazing!
