Finish the assembled of the Front Wheels and the Drive Sprockets…without any problems.
There have 2 different styles of the Road Wheels. Found one group of the Road Wheels (Parts # A27 and A28) have about 0.3mm gap between the inside of the 2 halves of Wheels parts.
I trimmed down the boss of the Parts # A28 by 0.3mm. It is well matched now.
