SRAM X9 3x9 Speed Trigger Shifter 2013
Updated with XX/X0-inspired cartridge ball bearings in the pull-lever/trigger for smoother shifting over traditional bushing design.
I put these on my Bike-E recumbent which by its design has extra long shifter cables which can be problematic. These X-9's work flawlessly. If there is a con, it is that they do give you an indicator of just exactly which gear you are in. You can glance down and see which gear your front derailleur is in, but for the rear it is, am I at stasis, or do I need an up or a down shift? Is that a problem? Hmmm, not sure that it is.
