Fitter or no fitter, one should never own/ride two similar bikes with different crank lengths. I know I will get howls of protest from the 41, but there it is. There is one that is right for you, and every road bike you own should be equipped with it.

170 on the fixie, 172.5 on the Scapin, 175 on the MTBs. I don't even know what's on the Lemond. Egads! They might be wrong 
If I had my druthers I'd go 172.5 on MTB and 170 on road but 172.5 MTB cranks aren't very common.

@RollCNY same question for you- why the different crank lengths?

Saying that you manage to deal with a variety of crank lengths os not the same thing as calling poppycock on the notion of them all being the same. When I am building a new bike, should I mot match the crank length with my preference? What is the upside of that?

Sometimes I ride with a 172.5 on the drive side and 170mm on the non drive side.

On a related note,
I've been obsessed with these since I learned of their existence.

Can you really tell the difference between a 170 crankset and a 172.5 one in a double blinded test ? Have you run this study ?
Where can I see the results ? What was your control group size ? Experimental group data ? Are you not at Lake Tahoe ?
Why are you not out watching the sunset ?

No, not you. It's was @rpenmanparker. Only because he didn't understand about my cycling crush.

...what's the purpose of the bike ? What's the BB height ? Are you always cornering aggressively so that pedal strike is a concern ?

Nah. I just don't want to get on one bike and have it be different than the others hanging next to it. It doesn't cost any more to have all your cranks match. What possible reason can you give for not? Saying it does not seem to matter to you is not the same as it being the right thing to do.
The sparrow was bought used with 170s and I will again have to pay $ to swap out.

Yes used is a different situation. But for new, crank length, bar width and stem length should be made right at no additional cost at the time of purchase. My opinion anyway. In my situation it is moot since I build my own bikes from frames and parts. It is no more expensive to get the right size than the wrong. And in your case the majority of the extra expense should be offset by sale of the original parts. So specifically you should be able to get a similarly used 165 mm crank for the Trek on ebay for little more than you can turn around and sell the used one that came with the bike.
