    Does stand and mash smaller cog affect chain more?

    Question.. When we sit and spin on a climb in a big granny cog it feels nice and easy with little resistance. When we stand and mash a climb in a small cog it feels like we're generating an insane amount of torque on the chain.

    So is standing and mashing a smaller cog affecting the chain more and going to stretch it more?

    Yes. Riding in a smaller front chainring is harder on both the chain and the cassette, because there is greater force being put through the chain than with a larger cog.

    Chainline and amount of force aside, more teeth engaged with the chain spreads the load across more of the chain and will wear the drivetrain less than fewer teeth engaged with the chain to do the same job.

    Yes, IME mashers pushing big gears stretch chains faster than spinners.
