Ergonomic innovation is probably more critical to the higher standard of the new 10-speed S.T.I. levers than the added gearing.  The narrower cradle-style perch welcomes the high-on-the-hood riding style and accommodates all sizes of hands.  The shift internals borrow the robustness from our MTB
technology which results in a smooth and effortless shift.

    • Ergonomic design : Refined lever hood for improved ergonomics.
    • Robust internal mechanism
    • Effortless shifting : Shift effort is reduced on the release lever.
    • Short stroke shifting : Inward shift stroke distance is reduced by 10mm.
