Going from 172.5mm to 170mm cranks
Hi all,
So a crankset that I recently bought only comes in 165mm, 170mm, and 175mm sizing. I've generally been running a 172.5mm on my bikes for years. I ended up buying the new crankset in the 170mm size and did a test ride yesterday. Didn't think I'd notice a difference but when out on the test ride everything just felt "right". I couldn't have imagined that a 2.5mm change would make that much difference, but something just felt better. The q-factor on the new cranks is also about 5mm wider so this could also have contributed. Thoughts from those with a bit more experience appreciated. |

What do you need to know if it felt “right”

Different crank length also slightly changes your bb-saddle height feel as well.

I started out in 170's and rode them for years, then I switched to 172.5's for cycocross and have them on 4 bikes. I've thought about switching back as it them helped me spin better but I don't think I can easily replace all my campy cranks.

You have to make some adjustments in my experience but they are not prohibitive. Rode 172.5 for many years. Think I like the 170 better. Slightly higher saddle. Kept the same setback as that feels like the appropriate balance point . I would err towards shorter

you know what Sheryl Crow would say...
If it makes you happy it can't be that bad.
