    What makes for smooth shifting?

    Is it the derailleurs, the trigger, or both?

    I was just wondering because I have XT triggers, XTR rear derailleur, XT front derailleur, and the shifting feels rough. I wonder maybe because my components are over 5 years old.

    Shifters make it feel smooth...but you need a good clean stiff der to make the feel happen.

    Oh and let off power when you shift.

    You need to tear down clean the gunk out of the RD springs and reassemble...easy to do big reward.

    Clean cables and housing contribute to smooth shifter more than anything.

    Everything contributes to the whole. Some things are inherent in the system like the shifting gates and chain working well together. Stiffer RD, combined with smooth running cables and shifters with crisp detents improve the action and finger feel of the system. A well maintained and lubed chain is more supple and responsive to the shift commands and engages sprockets more smoothly, and last, but definitely not least,how you shift; your timing, pedal rpm and pedal pressure probably makes the biggest difference of all.

    Listen to some riders shift, a quiet "clickety-click", like a train going through a switch. Other riders sound like a 30 year old truck with beat up synchros and an inept driver, "grind,crunch, clatter, pop doink" resonating and shaking the whole rear end of the bike.

    The key to solving any problem is to understand and address the underlying cause.

    Everything significant, in order of importance IMO:

    1. New and clean housing and cable.
    2. Absolute optimal cable tension.
    3. Straight derailleur hanger
    4. Good shifters (Sram X9 / Shimano XT upwards)
    5. Cassette / Chain in good condition and well lubricated.
    6. Good Derailleur. (Yes derailleur is at the bottom of list - have found it doesn't play a big role in crisp shifting).
