As the Drive sprocket for RD 50, the largest number
The number of StandardDrive sprocket for RD 50 is 12, but this time I bought 15.
Even though we had 15 when we purchased it in July, even if we choose to write Impression, we can only pick up to 14.
Even if you do not go up with Engine Power, you can not increase the maximum speed even if you increase the number, but it is a lot of fun to try. I currently own 12, 13, 15, but both are well-structured and use properly according to circumstances.
