Which crank bearings ?

[Dean111]

Can anyone tell me what bearings i require for an old cannondale. I was told it is a standard 68mm bottom bracket.

Then would it be simply replacing bearings or is this a sealed unit that needs to be purchased ?

Photos of the bottom bracket will be a good start.

Good old fashioned sealed unit.  Shimano BB-UN55 68mm but you can confirm by measuring the width of the frame. 

Cheap and cheerful and most bike shops can sort it out.

Aah thank you Sir, i was quoted outrageous prices by some with questionable intentions. The width of the crank "tube" on the outside you mean ?

Good old fashioned Square tapper bearing just need the correct lenght 110mm 113mm up to 122mm. Cost around R180.00 and probably R50.00 labour. 

You need a crank puller to remove the cranks and a multi spline BB tool to remove and replace the BB.

If you in the south of Jhb  alberton I can sort it out
