Shimano still lists 11-32 11-34 11-36 because clearly 9s road bikes don't exist.
Have some sympathy for people who are still on seven speed, which has replaced six speed as the rock-bottom sub-entry-level quality. SRAM lists only a 12-32 (apart from their "gravity" 7s) Shimano has 11-28 12-28 12-32. Microshift has 12-28, SunRace lists 12-24 11-28 12-28 - the only 24t low out of the whole lot. What do I do about replacing my 12-21 7s? Even now when there's 7s stock still in the system, I'm not seeing any 12-21t from regular suppliers, just used or overpriced stuff on eBay.
