    Seems like the standard go-to size crank length is 172.5. I went from 172.5 to 175.0 on a bike mainly because the on sale cranks I wanted weren't available in 172.5. I can tell absolutely no difference. Look at a ruler and see how big 2.5mm, or even 5mm is. You can probably move your saddle twice that distance up or down and barely notice. Cleats and shoe soles probably differ by more than 5 mm.

    IMO, buying a set of 172.5 mm cranks, when you have a perfectly good set that's only 2.5 mm shorter is a waste of money. There's people on this board who say they feel the difference between a butyl tube and a latex tube, or a carbon versus aluminum seat post. I'm not one of these people.

    Kinda surprised at the responses here.

    Mountain bike background, about 5'11, Large (18-19in) MTB and 56cm CX bikes.

    My MTBs always came with 175, CX bike came with 172.5, was very noticable, I hated it and switched to 175, but I mash a lot.

    Oh, good idea! Why didn't I think of that?

    Except of course I did. Almost anyone who takes the time to post a thread has researched it first because google is now well known. However, they sometimes feel unsatisfied and or want new opinions.

    You should consider going to a library and burning all books on what you deem redundant subjects

    I went from 170mm to 172.5mm crank arm and did notice a difference in torque. I like 172.5mm better. I guess I'm a masher.

    Look at a ruler and see how big 2.5mm, or even 5mm is.
    When you are tightening or loosening a big bolt with a wrench, try changing the hand position by 2.5mm and see what happens.

    Although I haven't tried the 172.5 yet I imagine this is how I will feel and I'm pretty much set on moving up from 170 on my new bike.
