Hi all,
Got some issues with my bottom bracket at the moment and in need of an overhaul, I have a press fit bottom bracket and am struggling to identify exactly what make / brand I should be looking at. Upon searching for a "press fit" bottom bracket I can't seem to get any results. I'm running 105 running gear on an Avanti Quantam. Can anyone help?
Since you haven't been very specific, let me generalize by saying you should
replace like-with-like ...
If the crank is Campagnolo, for example, you would get a Campagnolo BB which is appropriate to the particular crankset.
If the crank is Shimano, then you should get a Shimano BB for the particular vintage of crankset. Because you are so vague in your description, here's a good instance of following the marketing department's suggestion that you match a 105 BB with a 105 crank, an Ultegra BB with an Ultegra crank, etc. to avoid getting the wrong BB.
In other words, identify the crankset, and then buy an appropriate BB + tool(s) OR
bring your bike to your LBS.
If you have an FSA MegaExo crankset, then you should probably consider getting a Shimano Hollowtech II BB as a direct replacement ... the Shimano Hollowtech II BB supposedly has better (longer lasting) bearings than the FSA MegaExo BB (I don't know if that's true, or not).
You CAN theoretically remove the plastic cover which shrouds the bearing, then READ the specific information molded onto the cartridge bearing's plastic cover, and buy the appropriate replacement bearings ...
OR, consider buying a new BB & crank combination if you happen to have an older, square taper BB (not that there is anything wrong with that design).
