I've broken

[gb155]

The plastic bit that goes onto the "end " of my BB

Can I get a replacement or do I need a whole new BB ?

 

[gb155]

Is it called the cup?

 

[Alien8]

Yes, that will be an adjustable cup.

Never seen them for sale but if you pop in to your LBS they might have one they could let you have FOC from an old BB they have replaced.

Note that for BBs with plastic cups you should always install/remove the metal fixed cup first to minimise strain on the more fragile plastic cup.

If you can't get one quickly, then I am pretty sure I have an old square taper BB floating around in my bits bin, you would be welcome to the plastic threaded bits if you want.

I may have one or two - I will check later. Is this on the tourer ?

They aren't difficult to break.

Yup that's the one

I feel better you saying that :-)

Make sure the threads in the frame are really cleaned.

I'll get back to you later. I should have one unused plastic cup, and possibly an alloy one (although that's been used and may not fit that bb). My MTB tends to eat BB's every two years or so, so I re-use the alloy cup (for obvious reasons), but this time it would not fit the new BB.

I can drop one off - I'll text you if I find some !

Gaz, found the plastic one in the spares box.

I can pop it through the letterbox over the weekend if you wish (in an envelope to stop it rolling away )

Hehe , thanks dude , if it's easer I can call round to yours for it

The might make me look/sound mire stupid than I do! But the plastic bit, does it go drive or none drive side ?

Gaz

 

[rusty bearing]

plastic bit is non drive side.

 

[gb155]

plastic bit is non drive side.

Ahhhhhh

 

[fossyant]

Fit BB shell from drive side, don't fully tighten just yet. Now fit plastic cup and tighten slightly so it engages the BB casing. Now tighten drive side. Then continue to tighten the cup.

The cup may stick out 5mm or it may sit flush - depends on frame and BB. Tighten cup until you feel alot of resistance.

I'll drop it in over the weekend - need to go out and get petrol for my car at some point as it's running on fumes !

Thanks Foz - it's like learning to ride again

I've rode for 3 years and done bugger all "fettling"

This morning my front wheel cone was lose, I adjusted it then asked a guy at work to check it, he said it was spot on - I was well chuffed :-)

I'll get there - it's just the start of the learning curve

having the tools and the confidence\backup is important. A decent set of allen keys is a good start...having Cyclechat on hand is a very reassuring...having Fossy on call is fool proof!
