My knees are getting pretty excited about the experiment Unfortunately, 'cause 165mm isn't very popular, many online shops don't even carry that size.
    Why don't you try with a 105 instead? That would be a pretty inexpensive try. If you like it, sell the crank and upgrade. At worst it will set you back 50$.

    You'll notice, no doubt about that.

    How many revs do you think you have done on your current ones? That motions is LOCKED IN to your brain. This will make your brain notice. Tell your brain to shut up and just get your spin going.

    Personally, I found it easier to spin smoothly in high gears and high rpms on shorter cranks. My spin "flew apart" later. So were I to care about top end sprinting, I would go short. YMMV.

    I haven't ridding my short crank bike in over 10 years now. It was never a big enough deal to make me care one way or another.... except when I went from 170s to 175s on my first MTB and clipped quite a few rocks and roots until I adapted. That was.... bothersome.

    Great advice.

    Going low for trying something you have doubts about is often a good idea. Stems are another example, though for fit, not function.

    Cool

    I decided that to save a few bucks to try the shorter crank thing, I'm just going to do the following to my new Ultegra R8000 cranks so I can switch back to the regular length for almost $0...



    Psych! If you believe I'd do that to my new cranks, I've got a bridge to sell you.

    Thanks, but I'm in the market for 165mm Shimano FC-R8000 cranks.

    Here is an interesting and thorough analysis of using a short crank for shorter riders.


    Super-simplified, it tooks that a shorter crank does not decrease torque, it does reduce instantaneous acceleration (force) and fatigue. Saddle fore/aft has more effect on opening hip angle than does crank length and may be a better option for that.

    Another interesting point for some of you. As one ages, you might get more pain in the hips, so a shorter crank reduces how far your hip rises and is pushed against, which could reduce pain. If you want to see the whole video, not just that summary:

    You could try it with 105's? I guess this was a joke? I'd try it if I was interested.
