Cycle Shop thing...

Right Ive had enough of this disturbing clanking noise on my bike, and had enough shying away from riding it.

So I called a bike shop. :)

Explained the clanking noise im getting from the bottom bracket, asked if I tightened the lock ring on the bike recently and I had done about 4 months ago (noise started about 3 months ago), and he instantly said something about cartridge bearings breaking up when tightened up too tight.

So... £18.50 for a full strip out of the bottom bracket, and remove the broken cages/cartridge bearings, and replace with grease and new bearings (non-cartridge), as he doesnt rate cartridge bearings... apparantly theyre good, but you can fit more bearings in without one so less load for each to bear, and they wear out too fast.

Sound reasonable?

They are caged bearings, not cartridge ones.  Sorry to be picky :D

Caged bearings are a stupid way to go on a bottom bracket, as the cage takes up space which could be occupied by another couple load bearing quality grade 25 bearings. Only reason for them is speed of manufacture. Your shop is right. Using caged bearing in headsets is  quite reasonable and common on the other hand.

As for the price. Thats fair enough, hes got to pay lights. In the future, if youre threaded properly for it, a bog standard cartridge bottom bracket costs £10 or so and can be screwed in with a cheap tool in a couple minutes.

This is what a cartridge bottom bracket looks like:



Its not necessarily more durable than a well adjusted servicable cup and cone model, which is still the best choice for trips to Timbuktu, but a Shimano or generic one is cheap enough to make them practical.

Your first paragraph is exactly what he said well pretty much.  :lol:

"Stupid machine built bikes, thats why they use em see, bloody stupid idea, ill whip em out pack it full of grease and shove a load of bearings in, should sort you out nicely. Bloody stupid caged bearings." :lol:

I have BB removers and crank pullers and all sorts of schnanigans as part of that bike toolkit I bought a while ago, just if I do something myself it takes months... I start doing it, break something, or get bored then do nothing for months, seems easier to shove bike in in the morning.. get bike back in the night and it all done.

Brake adjusting, gear adjusting... now that is a five minute job, tyres and wheels... again 5 minutes, but things that involve stripping things out and gunk, I will just f**k up somewhat im sure of it.

Got on my bike today for the first time in 2 months, despite the clanking (dont care now I know its getting done tomorrow), its was such a bloody brilliant ride down here, didnt last nearly as long as Id hoped. Higher average speed too... think I was happily "stuck in a rut" of 9th and 10th gears for riding around, today I knocked it up 2 notches and my average on the ride to work was 15.7mph. Gonna see if I can keep it that way. May even ride it to the Gym later for kicks, instead of a "ah crap work" I got a "Woo!!! bike ride!" feeling :D
