Hi Guys,

I have a question, I have bought shimano 105 chainrings, and I thought I had a shimano 105 crank, but apparantly it was another sort. Now I have mounted it temporarily, but there is a slight mismatch in the fit. I cant post a picture I see, so I have added a link to it. https://imgur.com/a/y8DdZYB

Ofcourse I will fix this, but could it hurt to have it like this for a ride or 2? I live in the Netherlands, so it wont endure massive forces in climbs etc.

For the fix I might have another question, my whole bike is 11 speed, but I can only find available 105 cranks with 12 speed. What exactly is the difference here in the crank?

Thanks for your help!
