Shimano Ultegra R8100-P cranks zijn voorzien van een dubbelzijdige vermogenssensor, ontworpen voor rijders die op zoek zijn naar precisie en prestaties. Met sensoren in beide cranks bieden ze een extreem betrouwbare vermogensmeting met een geclaimde nauwkeurigheid van ±2%, ideaal voor het analyseren van de links-rechts vermogensverdeling en het optimaliseren van de trapefficiëntie. Ze zijn compatibel met Shimano 12-speed groepen en ideaal voor intensieve training en wegwedstrijden.

De R8100-P cranks zijn gemaakt met Hollowtech II technologie en combineren lichtheid en stijfheid voor maximale krachtoverbrenging. Leverbare lengtes van 160 tot 175 mm en kettingbladcombinaties van 50-34 T of 52-36 T maken een nauwkeurige aanpassing aan je rijstijl en behoeften mogelijk. Het holle ontwerp van de aluminium cranks en kettingbladen biedt uitstekende sterkte en vermindert tegelijkertijd het gewicht, voor optimale prestaties op de weg of in tijdritten.

De vermogensmeter is voorzien van ANT+ en Bluetooth LE connectiviteit, voor naadloze communicatie met GPS-meters, trainingsapps en real-time coachingsystemen. De oplaadbare Li-ion batterij biedt tot 300 uur autonomie, waardoor lange trainingssessies zonder onderbreking mogelijk zijn.

Tot slot zijn de R8100-P cranks compatibel met een breed scala aan press-fit trapassen, waaronder SM-BB9000 en SM-BB72-41B. De montage is eenvoudig en veilig dankzij de precisietoleranties van Shimano, waardoor een stabiele montage en trappen zonder vermogensverlies gegarandeerd zijn. Deze cranks zijn een essentieel gereedschap voor ambitieuze fietsers die op zoek zijn naar kracht, betrouwbaarheid en geavanceerde technologie.

Excellent value for an automatic watch, keeps VERY good time.
Color: Grey, Color: Grey
I've only had the watch for a day but wanted to leave a quick review on it to share a couple of notes. So far it keeps VERY good time, better than any of the automatics I own (including a Rolex Submariner, Tag Heuer Aquaracer, Tag Heuer Formula One, and several other sub $1k watches). I set it to an atomic time app on my phone yesterday and 24 hours later it's still SPOT on - hasn't gained/lost even a 1/10 of a second. I was shocked to see it's kept PERFECT time for the last day, I'm really blown away so far. I've worn it the entire time, we'll see how well it keeps time while being stored in a winder. This picture shown is the watch with a 22mm leather band on it, fit's without any issues (just need to squeeze in the leather a tad). I doubt it would work with a 22mm metal bracelet, but leather works great. Just FYI since the 21mm lug width is kind of odd. The face isn't quite a lustrious as the images make it look, but it's still a great-looking watch. For a sub $1000 automatic you can't go wrong, this is a fantastic watch at a great price. It'll be my daily driver for some time I'm sure. If I have any issues in the future I'll update the review.

It looks really cool and striking.

Really cool and beautiful watch. Although my specific unit runs 5 seconds fast every day—at first it’s annoying, but eventually you stop caring. 🤣

A Beautiful Timepiece at an Awesome Price!!
Color: Grey, Color: Grey
I have lusted after this watch for four months. I first tried on a similar model (stainless steel band with a green face) in a local jewelry shop (Spitz Jewlers, Walnut Creek, CA, USA). It was "love at first sight," even if I didn't love the white lines on the face from 12-6 and 3-9. At the time, the MSRP was $775. The MSRP has since increased to $795. But I bought this beauty on Amazon.com for only $524.99; after applying the cash-back from my Prime credit card, this watch costs only $498.75. This was "the offer that I could not refuse," to quote from "The Godfather." Accuracy could be better: after only a few days, it is now 7 seconds behind my phone (to which I set my new watch). But I don't really care about that all that much. This is why I rated "accuracy" at 4 stars, but my overall review is 5 stars. My video shows the date changing suddenly at 11:59:59pm, just how I want it; in another photo, you can see that my Seiko changes the date more slowly, which I do not like. This watch is absolutely phenomenally beautiful. If you're on the fence over whether to make this purchase, then I would say "go for it!" You will not find a prettier, more accurate watch at a lower price in ANY store in the entire USA.

Classy and sporty. Great value!
Color: Grey, Color: Grey
Excellent watch for the price. Looks sporty and dressy. More towards dress watch. Blue is dynamic. Strongly recommend blue for sporty feel. I was thinking of aqua terra. This come close to it with a price less than what i would have paid my state tax for omega aqua terra. My only concern is bracelet which i feel kind of OK. Better bracelet design would have made this watch much superior. 21 lug width is awful. Other than that, nothing to complain.
