First introduced on Shimano MTB groupsets, this unique chain-to-cassette interface smoothly guides the chain up and down the cassette for fast, precise shifting in both directions, even under extreme pedaling loads. So you no longer need to reduce the pressure on the pedals before shifting. HYPERGLIDE+, in fact, guarantees smooth and efficient gear changes, always.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHOLLOWGLIDE\u003cbr\u003e\u003c\/strong\u003eThe high-rigidity hollow structure reduces weight while maintaining rigidity.

The rigidity of the crankset guarantees Lefficiency in pedaling, while lightness, a key element of the crankset, facilitates the cyclist on long distances, where it is necessary to pedal more. The HOLLOWTECH technology, which consists of an ultra-light hollow crank that maintains the rigidity unchanged, was developed by SHIMANO with Lthe use of its exclusive forging technologies. LThe addition of HOLLOWTECH II technology integrates Lthe bottom bracket axis with the right crank, ensuring greater rigidity, weight reduction and high dimensional stability. The bottom bracket's axial bearing system ensures better weight distribution, which translates into more efficient power transfer. The HOLLOWTECH II crankset was developed pursuing an optimal balance between stiffness and rolling performance, and thus an ultra-light and very elegant design was achieved.\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 derailleur\u003c\/li\u003e\n\u003cli\u003ex1 Shimano Ultegra Di2 FD-R8150 2x12V 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 shifters\u003c\/li\u003e\n\u003cli style=\"font-weight: bold;\"\u003e\u003cstrong\u003ex1 Shimano Ultegra CS-R8101-12 12V 11-34T sprocket pack\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 EW-EC300 USB Type A charging cable\u003c\/li\u003e\n\u003cli\u003ex2 EW-SD300 Di2 electronic harness cable\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 can be shipped in aftermarket box or OEM packaging depending on the 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":55505930027384,"sku":"gruppo-shimano-ultegra-di2-8170-pressfit-165-52-36","price":1277.95,"currency_code":"EUR","in_stock":false},{"title":"Crank length: 165 \/ BSA SM-BBR60 \/ 52-36","offer_id":55505930060152,"sku":"gruppo-shimano-ultegra-di2-8170-bsa-165-52-36","price":1277.95,"currency_code":"EUR","in_stock":false},{"title":"Crank length: 170 \/ Pressfit SM-BB72\/41 \/ 52-36","offer_id":55505930092920,"sku":"gruppo-shimano-ultegra-di2-8170-pressfit-170-52-36","price":1277.95,"currency_code":"EUR","in_stock":false},{"title":"Crank length: 170 \/ BSA SM-BBR60 \/ 52-36","offer_id":55505930125688,"sku":"gruppo-shimano-ultegra-di2-8170-bsa-170-52-36","price":1277.95,"currency_code":"EUR","in_stock":false},{"title":"Crank Length: 172.5 \/ Pressfit SM-BB72\/41 \/ 52-36","offer_id":55505930158456,"sku":"gruppo-shimano-ultegra-di2-8170-pressfit-172-5-52-36","price":1277.95,"currency_code":"EUR","in_stock":false},{"title":"Crank Length: 172.5 \/ BSA SM-BBR60 \/ 52-36","offer_id":55505930191224,"sku":"gruppo-shimano-ultegra-di2-8170-bsa-172-5-52-36","price":1277.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0646\/6384\/7052\/files\/SHI-8435572994419-U_100_35678218-f87d-41c7-9b58-151c38a3fdc9.webp?v=1773965153","url":"https:\/\/evolutionbikesse.myshopify.com\/en\/products\/shimano-ultegra-di2-8170-12v-disc-groupset","provider":"Evolution Bikes COM","version":"1.0","type":"link"}
