Several months ago the metal plates on my durace pedals came away from the body (the holes where the screws went gave way). I removed the remains of the plates and carried in using them as I couldn't get a replacement plate. Which was annoying as I got these pedals "free" when I bought the bike a few years ago. Now, the body of the pedals have worn due to the missing plate and cleats la now sit quite loose. my only option is to replace them. I have been looking at the current 105 and ultegra r8000 pedals. I have read a review about the bearings on the 105s being on the outside and needing regular maintenance, whereas the ultegras are on tge inside. Also the 105s appear to have the metal plate screwed to the top in the same way as my durace pedals which failed, the ultegras appear "bonded". Has anyone had any of the above issues with 105 pedals (bearing life/top plate failure) ?
