Hi All

Can anyone tell me what size and where i go for some gen 2 profile crank bearings.

The spindle is 19mm and the inside of the cups appear to be 41.3mm Not sure what thickness i need and what actual outside diameter bearings i need. In a hurry as well as its for the bike i am building for Macmillan on the 21st. All mad panic now as i have left it till the last minute  :tickedoff: :uglystupid2:

Gary72:
have you got the old bearings, if you have there should be a ref no. on the side something like    6004 2rs.
The 6004 refers to the bearing size and the 2rs refers to the no of rubber seals. If you put the 6004 number into ebay some should come up.

virtualmeuk:
Sadly no. All i have are crank arms, spindle, bolts and cups :'(

steve:
they are imperial bearings
3/4, not 19mm, they are 19.050mm, which is 3/4 of an inch

virtualmeuk:
Cool. Thanks for the info. Any idea what size the outside needs to be and the thickness?

Cheers
Steve
