I bought a pair of Shimano brifters from eBay, brand new. They have a few bumps and marks on the plastic and metal parts that look like poor quality manufacturing to me. Can anyone tell from these photos whether these are legit? The model is Acera ST-EF65.
My tinfoil hat is on because they shipped from China, brand new without original packaging.
I was thinking maybe a good test is to dip the cables in water for a few hours and see if they rust. To see if they are truly stainless.
Update: While installing this, I noticed it does not have a hole to adjust brake pull between V or caliper style. The dealer manual says it should have this. Hmm...
