This results in a 58% decrease in ULTEGRA rear derailleur operating time and a 45% decrease in ULTEGRA front derailleur operating time over the previous DURA-ACE RD-R9150 rear derailleur.\n\t<\/li>\n<li>\n\t\tAbsolute reliability from a wired connection where it makes sense. New smaller diameter SD-300 wires connect the Di2 battery (BT-DN300) to front (FD-R8150) and rear derailleurs (RD-R8150). One internal battery makes for a simple charging solution and ensures a stable and high voltage connection to the derailleurs, contributing to Shimano\u2019s fastest-ever shifting. Tests show that the BT-DN300 battery lasts for 1000 km between charges. The STI shifter buttons are powered by coin-style CR1632 batteries which last for approximately 1.5-2 years of usage.\n\t<\/li>\n<li>\n\t\tA high security, fast processing and low power consumption proprietary chip circuit, which significantly decreases the chance of interference from external devices.\n\t<\/li>\n<li>\n\t\tThe new ULTEGRA rear derailleur is now the point at which the system is charged (replacing Shimano\u2019s SM-BCR2 charger) and it provides the wireless connection to STI shifters and other 3rd party devices (replacing the EW-WU111 wireless unit). Plus its integrated design provides the control point for changing Di2 operations and Synchronized Shifting modes, replacing the previous handlebar or in-frame Junction-A (SM-RS910) button.\n\t<\/li>\n<li>\n\t\tWhere the ULTEGRA derailleurs differ from DURA-ACE is in the construction. The DURA-ACE R9200 front and rear derailleurs weigh 96 g and 215 g respectively, versus ULTEGRA R8100 weights of 116 g and 262 g, resulting in a combined 67 g difference.\n\t<\/li>\n<\/ul>\n<div class=\"grid grid-cols-12 gap-4\">\n<div class=\"col-span-6\">\n\t\t<img decoding=\"async\" alt=\"202865_irmo_keizer.jpg\" class=\"ipsImage ipsImage_thumbnailed\" data-fileid=\"1689754\" data-ratio=\"66.67\" data-unique=\"1oq233yh8\" style=\"height: auto;\" width=\"1200\" src=\"https:\/\/wp-media.bikehub.co.za\/production\/uploads\/2023\/02\/202865_irmo_keizer.80cc207d76008439207de3be603e8593.jpg\" title=\"\">\n\t<\/div>\n<div class=\"col-span-6\">\n\t\t<img decoding=\"async\" alt=\"202868_irmo_keizer.jpg\" class=\"ipsImage ipsImage_thumbnailed\" data-fileid=\"1689753\" data-ratio=\"66.67\" data-unique=\"bk4gbgnpp\" style=\"height: auto;\" width=\"1200\" src=\"https:\/\/wp-media.bikehub.co.za\/production\/uploads\/2023\/02\/202868_irmo_keizer.8c021b30d800af30e1bc8610305a196e.jpg\" title=\"\">\n\t<\/div>\n<\/div>\n<p>\n\t<br \/>\n\t<strong>ULTEGRA control interface<\/strong><\/p>\n<p>\tFor climbing, sprinting or time trials, Shimano has balanced ULTEGRA\u2019s comfort, looks and aerodynamic gains with unparalleled ergonomics.\n<\/p>\n<p>\n\t<img decoding=\"async\" alt=\"399164-ULTEGRA_R8100_Cockpit.png\" class=\"ipsImage ipsImage_thumbnailed\" data-fileid=\"1689751\" data-ratio=\"51.75\" data-unique=\"19fsvihj2\" style=\"height: auto;\" width=\"1200\" src=\"https:\/\/wp-media.bikehub.co.za\/production\/uploads\/2023\/02\/399164-ULTEGRA_R8100_Cockpit.cf9b250d72e989383a5b297c38c6df69.png\" title=\"\"><br \/>\n\tNew ULTEGRA 2&#215;12-speed wireless hydraulic disc brake shifters (ST-R8170) now come with a raised head portion with a slight inward curve and increased area between the shifter and the handlebar to bring improved comfort and control.

Dual-sided data is provided by Shimano\u2019s proprietary strain gauges on both crank arms. ULTEGRA powermeters uses Bluetooth and ANT+ technology to transmit data.\n<\/p>\n<p>\n\tPower meter and non-power meter cranksets come in either 50-34T or 52-36T gear combinations with crank arm lengths of 160, 165, 170, 172.5 and 175 mm.

The result is a quieter system, achieved through less heat deformation of the rotor and less temporary interference between the pad and the rotor.\n<\/p>\n<p>\n\tFurthermore, brake maintenance has also been improved. Now it is possible to bleed the brake without removing the caliper (BR-R8170) from the frame thanks to a separate bleed port and valve screw. A new funnel and bleed spacer also help improve the bleeding process.\n<\/p>\n<p>\n\tNew ULTEGRA brake calipers weigh 282 g per pair versus the DURA-ACE weight of 229 g.\n<\/p>\n<p>\n\t<br \/>\n\t<strong>ULTEGRA wheel system<\/strong><\/p>\n<p>\tThe last pillar in ULTEGRA\u2019s development is the final point between the rider\u2019s input and the speed output.
