Shimano have been doing some work on their most popular groupsets. The 6700 series Ultegra is now able to accommodate a 30 tooth cog. Of course Shimano have created a 12-30T cassette to match. This cassette, like all Ultegra cassettes has an aluminium sprocket carrier and Hyperglide shifting.
Shimano’s 105 and Tiagra groupsets have also benefitted from the technology. The rear derailleurs in both of these groupsets will now go up to a 32 tooth cog.
