Guys i have to anounce that for the time the middle Koyo bearings for the MC21/28 is out... I have only the outer bearings left... I am trying to contact Koyo to find out if they are going to produce these bearings again but i don't have a clear answer from them yet... They told me to order the bearings but they don't know yet if they are going to deliver to me... I am also searching for alternatives factorys that produce bearings and i have came up with someone that claims that he produce the same bearing as the Koyo middle bearing... But i don't believe anything till i see it my self... If i have any news i will post it right away in the forum...
