Hello, I am 5’4" and ride a 48cm Cervelo S3.
I am not sure but I think my cranks are 170mm. I can’t find any markings on the cranks that confirm the length.
This is my only bike and I would use it for both road riding and triathlon.
I was curious to hear feedback if I should consider running 165mm cranks all the time?
I definitely don’t want to swap cranks depending on the ride I am doing that day.
If I should look at 165mm cranks, how do I shop for them in the second hand market and confirm they will work/fit on my bike. I always like to save a bit of money if I can but don’t want to buy a 165mm crank if it is not compatible with my bike.
Thank you for any feedback and guidance you can provide.
