The True Spirit of the Sport
Pro Tour Technology: The ULTEGRA series is "pro-proven" as it is a direct trickle down from the DURA-ACE group. It stands for state-of-the-art technology, proven in pro races.
Traditionally seen as the benchmark groupset for high-end but not necessarily racing road bikes, Shimano Ultegra is an 11-speed system with a lot of the same technology as Dura-Ace, just wrapped in a less weight-conscious packaging. It’s still lighter than 105, though, and features the same performance benefits such as smooth gear changes and excellent braking. The rear cassette will work with sprockets of up to 32-tooth, and again the dual-pivot brake calipers also come in direct-mount versions. So it’s a great system that’s only been slightly overshadowed by the emergence of the cheaper 105 set-up.
