If one requires one to fit stock brake mount then this is no bother, and can be later modded by the end user if you decide to fit the TR mount. These are beefed up and based off the stock design weight comes in at 37.8g carbon stock is only 3mm and comes in at 42.6g TR rear plate 66.5g I've machined these on both sides because the pocket that's needed to clear the plastic brake hex washer, so fit and forget with no no binding washers. Ignore the steel dowels they are just used to line the part up to machine the underneath, these are also chamfered on the bottom side.
