Ho Im doing front end conversion on my er6 2010. And now looking for a front rim, since zx6 yokes take 25mm axle and my current rim is 20mm. But i just tough of taking er6 6004 (20x42x12) and replacing it with 6905 (25x42x12) one. Only concern is will this bearing do the job for me? I read some forums and found some info on it but no exact answer. And anyone would know where i could find 6905 bearing as it seems like there is only 2 options costume made one for£100 a piece, which is not worth the trouble. Or getting one from China, which would take ages to get here and would want to try avoid it. Help appreciated
