Shimano FC-R9100-P Dura-Ace Power Meter HollowTech II Road Chainset
The Shimano Dura Ace R9100 Power Meter Chainset is the most accurate and technically advanced power meter available. Using cutting edge Japanese technology Shimano have created a power meter capable of measuring strain, tension and pressure at precise levels that have previously been unobtainable. Shimano’s own power meter is one of the most aesthetically pleasing options on the market too, with very little bulk to impact on the already beautiful Dura Ace R9100 chainset it sits neatly within the crank arm and measures power from both the left and the right crank arms.

Mr HillGreat power meter chain set. Fantastic bargain price by Merlin. Easy installation and straightforward set up. Left / right balance within 2%, so none of the widely claimed problems in my case. A top class dura ace chain-set and power meter for the price of a double sided power meter! Looks the db’s too!
markSuperb upgrade from previous power meter (Stages) and paid less than what I paid for the single arm meter. Excellent price which was the reason for purchase
Mr GillesTrès bonne affaire, la qualité au top
Mr Moñux CalaviaUn producto perfecto para entrenar por vatios de calidad y precisión muy contento con la compra.
Mr KirbySo happy with this product (and the price from Merlin!!). The crank was pretty easy to install and get up and running. I have never had a problem with Shimano products. The finish on a crankset is beautiful and it came in perfect shape. Since I've been riding I've really enjoyed the accurate power numbers it sends to my Garmin head unit. I have tried all kinds of power measurement including cranksets, pedals, hubs and this one is by far the best.
Mrs AzevedoSimple to install, very clean in the bike, work good.
Mr ChanGood quality, delivery on time, very light product, internal battery, no more 2032.
ClaudioPurchased to replace Garmin Vector 3 pedals. Was easy to fit (recommend downloading and following shimano instructions though). Paired with Garmin 820. L/R balance seems a bit off (as reported by numerous reviewers) but otherwise working great. Would definitely recommend unless you want accurate L/R balance data.
Mr CONNELLGreat item, works exactly as its supposed to, installation easy, paired with edge 520 straight away, super looking quality chainset, expensive but with the discounts offered by Merlin fantastic buy
