I have a 2011 Force 1.0 and need to replace the rear derailleur. Can anyone tell me, what size cage I need? Long, medium or short?
Or can you tell me where I can find this information? I can't find any website with the info. All the websites just say Sram X9 10 speed, but I already know that.
How can I measure my derailleur to figure out which one I have?
Thanks for any info.
