Well it looks like Koyo have stopped doing the bearing for out cranks . so its Tai bearings only now . Lucky i have a reasonable stock for a few more of my cranks but then they will be no more . The tai ones you can get now are Ok not like 20 years back but do like to use jap if possible but like it or not if you cant get them you cant get them simple as that .
Yes yam still have them in stock at a fortune and engine ones are still ok its just the crank ones they are no longer doing . As i say i have anough stock to do several more rthen i just do them with 10 ball as standard there are other makes that can be used but no more Koyo
