could be, really hard to say

[AndreZA]

YOu could always just ask it "BB, is jy in jou tjops?"

 

If you don't feel grinding/tension while you spin it then it should still be fine.

[Mudsimus]

Your crank is not suppose to spin. I'm sure your bb is fine. But like mampara said if you feel it grinding....let it go.

[FanieFiets]

nope no grinding. Maar my fiets trap so moeilik en ek gaan nie vinniger nie, daar moet mechanical fout iewers wees! Of dalk moet ek meer train....

... of jou toolbox by die huis los

Jou BB's is klaar as jou Crank Arms nie net in n ronde aksie beweeg nie maar ook lings en regs play het, dan is hulle in hul moer, soms val die berrings sommer by die BB gebeelte uit, dus hoe ek gewoonlik weet dus tyd vir nuwes.

Faan as jou fiets moeilik trap, kyk of jou briek kabels nie te kort is en nou trek hulle heeltyd die briek blokkies teen die rim va,

 

 

 

Of vra oom Borman (net voor 3uur) anders gaan jy 2 ure vat om sy reply te lees en nie voor 5 klaar maak met tjaaila tyd .

 

 

 

want jy gaan seker more in C-D wegspring saam oom pops , trekker, smallrebel en die blou train narre?

[lowracer]

oo gaats. miskien is dit jou fiets wat die gasket geblaas het, nie jou buddy s'n nie.

wel, nou het jy 'n verskoning om of 'n nuwe raam, of sy fiets te koop!

 

 

 

[FanieFiets]

ja, dalk moet ek 'n wyfiefiets soek vir bietjie relaxation, te tense die afgelope tyd.

 

Sien julle manne more by Durbanville in C-D. Die blou train gaan loop, stukkende BB of nie!

Checking on your BB is another good reason why your chain should be fitted with a magic link.

 

To check your BB:

 

1) Fit a magic link (quick link, missing link, snap link...call it what you like) to your chain.

 

2)Wash your bike by putting it in a service stand, remove the chain and clean that in a bottle of degreaser. Shake like a cocktail.

 

3) Now inspect your BB. Put your ear against the seatpost, well out of harm's way. Spin the crank which is now liberated from the chain. If you hear smooth rumbling noises, your BB is fine. If you hear rough grinding, your BB is kaput. If you hear crushing sounds accompanied by pain, your head is too close to the crank and the pedal is hitting you in the teeth.

 

BB health has nothing to do with how much the cranks spin relative to the wheels. A very worn BB will spin freely when activated by thumb and forefinger whereas a new BB will have a lot of seal drag (good) and not spin at all.

can you change the bearings on a bb nowadays, or do you buy a new one?

[dirtrider]

You can change the bearings on anything that has bearings BUT in most cases you may need special tools like a good press to start with . Changing bearings on the "external" cap models in actually very easy and you can buy those bearings at half the price from bearing man , just take sample with .
