Le SHIMANO Dura-Ace Di2 R9270 2x12V groepset  vertegenwoordigt het toppunt van technologie en innovatie voor RACEFIETSEN. Na jaren van onderzoek heeft Shimano zijn snelste en meest geavanceerde aandrijving tot nu toe ontwikkeld. Deze 12-speed groepset is ontworpen voor fietsers die hun grenzen willen verleggen, met elk onderdeel geoptimaliseerd om kostbare seconden te besparen tijdens wedstrijden of intensieve tochten. Dankzij de Di2-technologie schakelt elke versnelling direct en nauwkeurig, zelfs onder de meest veeleisende omstandigheden. De compacte, ergonomische versnellingspook biedt optimale controle onder alle omstandigheden en biedt meer comfort en perfecte controle, ongeacht de rijpositie.

Het systeem biedt een aanzienlijk voordeel doordat de rijder energie bespaart en zich kan concentreren op het rijplezier en de vereiste inspanning zonder zich zorgen te hoeven maken over storingen in de transmissie. De versnellingen worden automatisch geschakeld door middel van een schakelaar, waardoor de schakelweg die nodig is voor mechanische systemen overbodig wordt. Deze functie is vooral handig om de versnellingen aan te passen aan veranderende wegomstandigheden.

Shimano D-FLY overbrugt de kloof tussen componententechnologie en Di2-software. D-Fly maakt connectiviteit mogelijk tussen Di2 systemen en ANT+/Bluetooth®LE compatibele accessoires zoals computers/GPS en verlichting. Het biedt ook een draadloze verbinding met Shimano's E-TUBE PROJECT Cyclist voor smartphones, waardoor de configuratie van de versnelling kan worden aangepast, op firmware-updates kan worden gecontroleerd en componentstoringen kunnen worden opgelost.

De verhouding van minder dan 1:1 van de SHIMANO Dura-Ace 12-speed aandrijving maakt het mogelijk om ambitieuzere uitdagingen bergop aan te gaan met meer controle over de inspanning. De gesynchroniseerde voorderailleur zorgt voor constant trappen en soepel schakelen, terwijl de E-TUBE PROJECT-applicatie aanpassing op maat mogelijk maakt. Of je nu de legendarische wegen van de Tour de France bedwingt of de plaatselijke heuvels beklimt, de DURA-ACE R9270 is ontworpen om je snelheid te maximaliseren en je prestaties te verbeteren met elke pedaalslag.

Loved it ♥️♥️♥️
Color: Blue, Size: Standard
Very comfortable and cool for sleeping. The memory foam provides excellent neck support and helps you rest better throughout the night. I loved the cooling cover because it truly feels cool and soft. Plus, it is easy to wash and maintains its high quality. Highly recommended.

Perfection!
Color: Blue, Size: Standard
This pillow is so good! Perfect firmness and enough support. It’s very comfortable and does help with sleep especially on hot nights! The cooling gel does a great job of keeping the pillow cooler. It’s a good size pillow for a twin bed. I also like that it can be very compact when taking with you, the memory foam compresses very easily and fluffs back up quickly, so it’s very adjustable. Great value for the money! I definitely recommend!

Good pillow that becomes warm faster than competitors
Color: Blue, Size: Standard
I have bought several cooling gel pillows and am quite happy with this one with one caveat, that it doesn't retain coolness as long as other cooling pillows like my sealy that fell apart. Now, a cooling pillow will never retain coolness indefinitely, neither will a normal pillow, but this one tends to become just a normal gel warmth about 30 minutes before my old Sealy so I can't give it a full recommendation. It does however seem to be a nice pillow otherwise with a nice supportive firmness and provides a nice sleeping experience as a pillow, and when it's cool it's quite cool. It holds up the coolness for about an hour while sleeping in a case normally and maybe close to two hours when I have the AC on.

Great cooling pillow, and cat-approved!
Color: Purple, Size: Standard, Color: Purple, Size: Standard
I've been using this EGOHOME cooling gel memory foam pillow for a few weeks now, and the cooling feature is definitely the standout for me. The reversible cooling cover really does what it promises — it feels noticeably cool to the touch, especially when the AC is on, and makes a big difference on warmer nights. It helps create that fresh, cool sleep surface that makes it easier to relax and fall asleep. Beyond the cooling comfort, the memory foam strikes a great balance between soft and supportive. It keeps my neck aligned whether I sleep on my side or back, and I’ve been waking up feeling more rested with much less neck stiffness than before. The removable, washable cover is also a practical plus. One small note: the cooling effect does gradually fade after an hour or two without AC, so pairing it with a fan or air conditioning helps maintain that cooler feel longer. And perhaps the highest endorsement I can offer: my cat Duoduo claimed it immediately. She’s been loafing on it with a look of complete ownership ever since — I’d say that’s the ultimate comfort test passed.

Cool, Supportive, and Very Comfortable Pillow
Color: Blue, Size: Standard, Color: Blue, Size: Standard
I really liked this pillow from the first night. It feels soft but still gives very good support to the head and neck, so it feels comfortable in different sleeping positions. I also liked the cooling side, which feels nice especially at night when the room gets warm. The pillow has a good shape, feels well made, and the cover is easy to remove and wash, which is very helpful for regular use. Overall, I feel this pillow is worth buying if you want comfort and support together. It gives a nice balance, not too hard and not too soft, and I woke up feeling more relaxed. The cooling feature, washable cover, and memory foam support make it very practical for everyday use. I am happy with this purchase and would definitely recommend it.
