Two different crank lenghts?
I have one bike with 170 cranks and one with 175. Are there any potential problems with switching back and forth between the two crank sizes?
Thanks.
Thanks.

Maybe you should switch them so you have one of each on each bike

If you feel it and don't like what you feel, that is a problem. Otherwise no. One does have to wonder how such a thing happens. Is one bike also much bigger than the other. That could be a bigger problem than the difference in the cranks. If both bikes are your proper size, the cranks shouldn't differ by more than 2.5 mm. Unless you mistakenly bought the wrong crank for a build that you did, of course.

I have 170 on fixed gear. One roadie with 172.5, one with 170, a couple of MTBs with 175.
I like long cranks in the hills, short ones on the flats.

Thanks, it sounds like I shouldn't worry about it unless it becomes a problem.
Both bikes seem to be the right frame size and, as far as I know, have the original cranks. The 170 cranks are on an old Schwinn Le Tour which is about 20 years older than the other bike.

Ha, I thought this was going to be a thread about leg length discrepancies - i.e. two crank lengths on the same bike!
As others have said, it's very common for the same rider to use different crank lengths for track, road, or MTB.

My crank lengths vary from 167.5 on the fixed gear to 180 on the bmx race bikes, with in-between lengths on road and mountain bikes. Personally, I can feel the difference, but after a few cranks, my legs seem to switch into to the right mode, and no problems.

Not to knock on an established rider like bob, but do you have a good sense of how long 5mm really is?
It's about | | <-- that long. Over the length of your entire leg, were talking about a single digit percentage of difference.
That said, I can feel the difference between my bikes with shorter and longer cranksets.

I honestly can't tell the difference.
