For those of you who are grip shift experts, what does the SRAM alphabet names mean on SRAM grip shifters? I know Shimano use names and SRAM use numbers. I'm a little confused by the designations ie: MRX, SRT and ESP. Is one a better level or just marketing.
Beware there are two different lines of SRAM grip shifters:
2:1 ratio which is Shimano compatible: MRX, Attack, Centera.
1:1 ratio only for SRAM: All other models.
