First introduced on Shimano MTB groupsets, this unique interface between chain and cassette smoothly guides the chain up and down the cassette for fast and precise shifting in both directions, even under extreme pedaling loads. So there's no need to reduce pedal pressure before shifting. HYPERGLIDE+ ensures smooth and efficient shifts, every time.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHOLLOWGLIDE\u003cbr\u003e\u003c\/strong\u003eThe high-stiffness hollow structure reduces weight while maintaining rigidity.

The crankset's stiffness ensures pedaling efficiency, while its lightweight, a key feature, helps the rider on long distances where more pedaling is required. HOLLOWTECH technology, consisting of an ultralight hollow crank arm that maintains stiffness, was developed by SHIMANO using its exclusive forging technologies. The addition of HOLLOWTECH II integrates the bottom bracket axle with the right crank arm, ensuring greater stiffness, weight reduction, and high dimensional stability. The bottom bracket's axial bearing system ensures better weight distribution, resulting in more efficient power transfer. The HOLLOWTECH II crankset was developed to achieve an optimal balance between stiffness and rolling performance, resulting in an ultralight and very elegant design.\u003c\/p\u003e\n\u003ch4\u003eIncluded:\u003c\/h4\u003e\n\u003cdiv class=\"expander\"\u003e\n\u003cdiv class=\"tab-expander\"\u003e\n\u003cdiv class=\"tab-expander-content\"\u003e\n\u003cul\u003e\n\u003cli\u003ex1 Shimano CN-M8100 Chain\u003c\/li\u003e\n\u003cli\u003ex1 Shimano Ultegra Di2 RD-R8150 12V Rear Derailleur\u003c\/li\u003e\n\u003cli\u003ex1 Shimano Ultegra Di2 FD-R8150 2x12V Front Derailleur\u003c\/li\u003e\n\u003cli\u003ex1 Shimano RT-CL800 160mm Disc\u003c\/li\u003e\n\u003cli\u003ex1 Shimano RT-CL800 160mm Disc\u003c\/li\u003e\n\u003cli\u003ex1 Pair of Shimano Ultegra Di2 ST-R8170 (disc) + BR-R8170 2x12V Shift\/Brake Levers\u003c\/li\u003e\n\u003cli style=\"font-weight: bold;\"\u003e\u003cstrong\u003ex1 Shimano Ultegra CS-R8101-12 12V 11-34T Cassette\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli style=\"font-weight: bold;\"\u003e\u003cstrong\u003ex1 Shimano ULTEGRA FC-R8100 Crankset\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003ex1 Shimano Di2 12V Wiring Components\u003c\/li\u003e\n\u003cli\u003ex1 Shimano Di2 BT-DN300 Internal Battery\u003c\/li\u003e\n\u003cli\u003ex1 USB Type A Charging Cable EW-EC300\u003c\/li\u003e\n\u003cli\u003ex2 Di2 Electronic Wiring Cable EW-SD300\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003ePressfit SM-BB72\/41 Bottom Bracket\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"expander\"\u003e\n\u003cdiv class=\"tab-expander\"\u003e\n\u003cdiv class=\"tab-expander-content\"\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eThe product may be shipped in aftermarket box or OEM packaging depending on supply\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Shimano","offers":[{"title":"Crank Length: 165 \/ Pressfit SM-BB72\/41 \/ 52-36","offer_id":56508498510204,"sku":"gruppo-shimano-ultegra-di2-8170-pressfit-165-52-36","price":1257.0,"currency_code":"EUR","in_stock":false},{"title":"Crank Length: 165 \/ BSA SM-BBR60 \/ 52-36","offer_id":56508928000380,"sku":"gruppo-shimano-ultegra-di2-8170-bsa-165-52-36","price":1257.0,"currency_code":"EUR","in_stock":false},{"title":"Crank Length: 170 \/ Pressfit SM-BB72\/41 \/ 52-36","offer_id":56508928033148,"sku":"gruppo-shimano-ultegra-di2-8170-pressfit-170-52-36","price":1257.0,"currency_code":"EUR","in_stock":false},{"title":"Crank Length: 170 \/ BSA SM-BBR60 \/ 52-36","offer_id":56508928065916,"sku":"gruppo-shimano-ultegra-di2-8170-bsa-170-52-36","price":1257.0,"currency_code":"EUR","in_stock":false},{"title":"Crank Length: 172.5 \/ Pressfit SM-BB72\/41 \/ 52-36","offer_id":56508498477436,"sku":"gruppo-shimano-ultegra-di2-8170-pressfit-172-5-52-36","price":1257.0,"currency_code":"EUR","in_stock":false},{"title":"Crank Length: 172.5 \/ BSA SM-BBR60 \/ 52-36","offer_id":56508928098684,"sku":"gruppo-shimano-ultegra-di2-8170-bsa-172-5-52-36","price":1257.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0756\/2051\/6162\/files\/SHI-8435572994419-U_100.webp?v=1773842049","url":"https:\/\/evolutionbikes.com\/products\/gruppo-shimano-ultegra-di2-8100-12v-disc","provider":"Evolution Bikes IT","version":"1.0","type":"link"}
