I'm building up a new bike and found this part on the floor under my work stand. So far today I've fitted the front and rear derailleurs and the sti levers. Does anyone know where it could of come from?
For reference it's a Specialized allez sprint and the group set is Shimano 105 di2. I've also unboxed and offered up the brakes but not started fitted yet so it could of come from there?
TIA

Looks like brake parts. Them washers are usually for setting brake calipers
Brake pad leveling washer perhaps …. Often they are a cone and a cup style washer that fit together and when tightened allow your pads to parallel the wheel perfectly. So they arnt tight on the leading or tailing edge ..
Brake caliper alignment washer.
Spherical washer
Too tall / round to be a conical brake washer. Looks like a washer for a seat post rail clamp
I agree with the others saying brake washers
For the cleats on your shoes.
Looks like an olive from some type of fluid line?
