I just went through my 3rd pair of Sh_tmano barend shifters. This time the black outer casing and inner ring cracked on the right shifter. It can only be used in friction mode. I have 18k miles on my trike and 3 pair of shifters is unacceptable. I had over 20k on my Stratus with Sram x-9 and never missed a beat. Shifting gears frequently on a recumbent is like banging gears on a tractor trailer but I expect them to last more than 5k miles. I just ordered on eBay for $77 shipped, Microshift TT 3x9 shifters from Taiwan. Hopefully they will be better.
TRYING TO KEEP RIDING!!!
