Bottom bracket bearing mode of failure
i had a gxp bb go kaput on me, the peddles seized up and wouldn’t turn, so I just lowered the saddle and straddled it, pushing along on the ground like on a victorian solid wheeled bike. They give you a fair bit of warning before they give up entirely ime, the noises really ramp up on every turn and there was fair bit of play in the cranks so you could tell it was on it’s way out.
Why not fix yourself? once you’ve done it once you wonder why you didn’t before, it’s dead easy.Posted 4 years ago
My BB is on its way out and is creaking and banging like one of those more mature ladies that Wayne Rooney used to enjoy spend time and money with. The problem is that I can’t get it sorted before my next ride. I can put up with the noise and the nasty feedback through the pedals, but I don’t want to be stuck in the middle of nowhere if it seizes up.
So, what is the worse that can happen?
Fixing it myself, before anyone says it, is not an option.Posted 4 years agobigyinnMember
You dont actually say what type of BB you have fitted to your bike.Posted 4 years ago
Dont leave it too long as there is a chance you can damage the axle with seized bearings, if its a HT2 BB.
Failing that remove the old one and fit a new one.
Out of interest if you dont want to fix it yourself why are you bothering to ask the question?binnersSubscriber
I’ve mad a Howitzer bottom bracket fail in pretty catastrophic manner. The bearing races completely disintegrated and dropped out of the frame!
Trying to turn the cranks resulted in a sound like a large group of German skeletons having a wild, debauched and vocal orgy inside a biscuit tinPosted 4 years ago
