How many of you have went to longer cranks? I had a stint on a set of 175's and feel like sometimes I would be better off. My legs are long!

I tried it, but couldn't get used to it. Like everything else fit related, I guess that it will be different for everyone.

I experimented with up to 180s, but settled on 175. My inseam is about 84.1
Its a long story, and if you search you can find this topic discussed extensively.
My summary would be: try it.

Been talked about ad infinitum on this forum. The answer would be use what is best for you.

I have long, long legs (over 90cm) I am 183cm (6foot) and going basically the opposite way with 172.5s. If anyone is interested, I have a set of English BB Sram Red cranks in good condition in 175 I will trade for 172.5 or even 170s. I need them for my TT.

My inseam is about 82cm and I am 1.76 tall. I rode 175's for 10+ yrs and now have the knee issues to show for it. While I cant, and wont, blame the crank length I cant help but wonder if shorter would have helped a bit. In my opinion there are horses for courses and this is true with crank length. Pedaling style will have a big impact on what feels right too.
I miss the Jerk because your stem is still too short.
Your saddle is probably too high as well.
Oh, and your cleats too far forward.

Bit more complicated than just changing cranks.
I am 5'10 Mr. average with pretty much standard proportions. Anything from 170 to 175 which I rode before is fine.
That said, I think the range of crank lengths available does not reflect the variation in people out there.
Also, the knee is quite capable of a wider range of motion, changing length by a few mm is fine, if you change the setup on your bike. On longer cranks, I lower my saddle obviously, and slide it back a bit more as well. I prefer 175mm cranks now that way.
