Mr ryan Definitely an upgrade on my old crank: easy installation, super-light, buttery smooth motion and pedal stroke, appears to maximize pedaling efficiency. Changes gears with beautiful efficiency and certainty. Expensive but worth every penny is the bottom line.
David Surprisingly lightweight to hold but It feels strong In use on the bike.
Disneysland Superb finish as is usual with Dura Ace, the best you can get?
Dylan Did not come in a Shimano box but other than that speedy delivery and what was inside was from Shimano. Stand out crankset, I needed to change down from a 53/39. I upgraded from a 9000 series and it looks much cooler on the bike. Marginal gains with a small weight saving over the old but but a chunk lighter than their 105.
Mr milnes This is an amazing product. Silky smooth, accurate chain engagement. Merlin Cycles delivery was even more amazing - they were so quick, particularly during these unforeseen circumstances. I was hoping to get the chainset quickly so as to avail of the great weather. You can order with 100% with this company. SUPERB
Sarah Excellent service as ever from Merlin. This has transformed my Bianchi. 5 stars!
Greg What can you say. Shimano quality crank, light stiff works a treat. Ramps on chainring result in precise shifting
Mr Hernandez Lighter , Stiffer , best looking Crank in my opinion. What is there not to like
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.
