These adaptors simply replace the standard cups on frames with oversize bottom bracket shells. Available in versions compatible with bottom bracket shells with 86.5 mm diameters and with BB30 bottom brackets, they are 20 grams lighter than standard cups. The new tool, UT-BB140, specially designed by Campagnolo®, is required for fitting them.
