I still can't get my brain wrapped around the fact that Shimano is not releasing any 11spd cassettes with 34t or 36t max cogs. You only get a 32t or a 40t cassette choice for big cogs
Regardless, it's neat to hear someone has already jumped on the super-sized cog setup.
Thank you for making sense of this....now I get it...the mix and match of MTN bike cassettes with the non 36 tooth Road cog (Shimano) was making me nuts.....probably just stick with the mountain bike cassettes.
Did I hear right on the rumors that Shimano is coming out with a 36 tooth road cassette? Will require a longer hanger over the current Ultegra derailleur?
