Shimano Dura Ace R9100 Chainset - 11 Speed
The R9100 series crankset achieves the ultimate in optimal power transfer. It does this through its broader Hollowtech II arm and a more reinforced outer chainring on its unique asymmetrical four-arm spider construction. The new R9100 cranks set the highest standards for ridity and lightness.

Carlos This is my second Dura ace groupset , I can’t say enough things about this , smooth shifting and beautiful looks.
Frederick Great service from Merlin. They are wizards at this. Shimano DA cranks really impress me. Power transfer is far superior to the carbon cranks I replaced, even though they are slightly heavier, weighing in at 632 grams than the carbon at 614 grams (458 from chainring side plus 174 for the other arm.) If you want to go FASTER, get these.
Mr Aruga リピート購入です。しっかりした作りで、美しく滑らかです。踏んだ分だけパワーに変えてくれるようなとても良い商品だと思います。合成もあるのに軽量でおススメします。
Roberto Great purchase. Fit and looks well in my bike. Very lightweight and small crankarm (165mm) makes pedalling smooth on my Triathlon bike. Recommended. Bought from Usa and arrived fast and good condition.
martyn The usual top quality product from Shimano and works really well with very smooth changing. Very pleased with the prompt delivery too.
Mrs cabon Super fast service again from Merlin. This great Dura Ace 9100 replaces my 9000 and I can tell you its stiffer as mentioned by Shimano. The rings are slightly closer than the older 9000 and the di2 gear changes are slightly better, and it looks great on my black Cervelo S5
Lenny Excellent crankset - very smooth, quiet, and stiff
Henri Excellent chainset. Running 170mm with my C60. Perfect match
Stanley Wong Very nice crankset from Shimano, very light but feels extremely solid when riding, improvement in power transfer is immediately noticeable. Merlin's customer service is very quick and helpful when answering my enquiry, very quick delivery and products arrived in perfect condition.
