    SRAM Grip Shift Help

    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.

    The MRX is worthless the plastic breaks I fish these out of bicycle shops trash and use the rubber grips. The older models ESP are indestructible I put 60000 miles on 2 sets and only changed when I went from a 7 cog to an 8 cog rear setup. Try to find a front shifter with 7 or 8 clicks some times they are called friction they are less finicky that the ones with 3 clicks. I have never used the newer ones for 9 rear cogs I do know they use different rubber grips than the MRX these grips last one year and cost $10 to replace. If you do buy these remove the handlebar fixing bolt and put antiseize on them they are prone to corrosion. If you have problems removing these bolts from older frozen ones it is possible to use the slightly larger english size hex wrench in stripped bolts.

    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.

    I know there's a Shimano and SRAM version. What I don't know is what's the difference between the Shimano versions?

    Poached from another forum:

    Yep.. ESP means 1:1 ratio. For sram, anything that has a number (X.0, X.9, X.7) is 1:1. Anything with a name (Rocket, Attack) is Shimano compatible.

    I am resurrecting this old thread to give what I think is a solid answer. If I understand the question, it's about the product hierarchy of SRAM's Shimano-compatible 2:1 grip shifters.

    From the SRAM spare parts catalog: http://cdn.sram.com/cdn/farfuture/x2...pc_rev_c_0.pdf

    pg. 44: SRAM X.0 / SRAM X.9 / SRAM X.7 / ROCKET / ATTACK - TWIST SHIFTER (2005-2011) 3x9
    pg. 45: 5.0 / CENTERA - TWIST SHIFTER 3x9
    pg. 46: 3.0 COMP / 3.0 / MRX COMP / MRX - TWIST SHIFTER 3x9

    So, Attack is somewhere near the upper-end products, Centera is similar to 5.0, and MRX Comp is similar to 3.0
