For those of you that know me even in the slightest way know that i am anal about things, be it the right parts, right bike or being clean and detailed. I have had this since last August and finall got all the parts I needed. The last thing being a 40 tooth sprocket, while not a Columbia original piece, it was the best I could get and it was NOS. It is a Wald replacement, which is just fine with me. Let me know what ya think of it. My son is very happy!
