The HOLLOWTECH II technology concept was designed to create an optimized crankset that minimizes the rider&#039;s effort required for propulsion. The crankset&#039;s high stiffness ensures efficient power transfer while pedaling, while its low weight reduces rider fatigue, especially on longer rides. The crankset was developed with an optimal ratio of stiffness to low weight in mind. HOLLOWTECH technology enables extremely lightweight, hollow crank arms, manufactured using SHIMANO&#039;s exclusive forging technology to achieve maximum stiffness. Additionally, on the HOLLOWTECH II crankset, the right crank arm is rigidly connected to the bottom bracket axle, achieving an optimal balance between maximum stiffness and minimum weight. The external bottom bracket provides better weight distribution and increased stability, resulting in more efficient power transfer.<\/p>\n<p>In the development of the HOLLOWTECH II crankset, emphasis was placed on an optimal balance between stiffness and rotational efficiency, as well as low weight and attractive appearance.<\/p>\n<p>High-quality precision seals. The HOLLOWTECH II crankset also features high-quality precision seals in the bearing area to extend durability and maintain excellent rotational efficiency in the long term.<\/p>\n<\/div>\n<div data-role=\"scope\">\n<h3>Scope of delivery<\/h3>\n<ul>\n<li>1 x Shimano 105 FC-R7100 crankset (see item description for details)<\/li>\n<\/ul>\n<\/div>\n<div data-role=\"video\" style=\"margin-top:30px\">\n<h3>Product video<\/h3>\n<div data-colname=\"de_ytvideoid\" style=\"margin-top:30px\">\n<div class=\"brlbs-cmpnt-container brlbs-cmpnt-content-blocker brlbs-cmpnt-with-individual-styles\" data-borlabs-cookie-content-blocker-id=\"youtube-content-blocker\" data-borlabs-cookie-content=\"PGlmcmFtZSBmcmFtZWJvcmRlcj0iMCIgaGVpZ2h0PSIzMDQiIHNyYz0iaHR0cHM6Ly93d3cueW91dHViZS1ub2Nvb2tpZS5jb20vZW1iZWQvS2lUcGFKVXJ0UW8iIHdpZHRoPSI1NDAiPjwvaWZyYW1lPg==\">\n<div class=\"brlbs-cmpnt-cb-preset-c brlbs-cmpnt-cb-youtube\">\n<div class=\"brlbs-cmpnt-cb-thumbnail\" style=\"background-image: url('https:\/\/stage.hibike.com\/wp-content\/uploads\/borlabs-cookie\/1\/yt_KiTpaJUrtQo_hqdefault.jpg')\"><\/div>\n<div class=\"brlbs-cmpnt-cb-main\">\n<div class=\"brlbs-cmpnt-cb-play-button\"><\/div>\n<div class=\"brlbs-cmpnt-cb-content\">\n<p class=\"brlbs-cmpnt-cb-description\">You are currently viewing placeholder content from <strong>YouTube<\/strong>.
