I have the need to replace the chain and sprocket on my bike and was wondering if anyone knows of an online retailer that sells quality chains/sprockets at reasonable prices? Is it just easier to go to Honda and pay their crazy prices? Also the rear sprocket is worn a reasonable amount but not damaged at all, so should I change just the chain (streched) or is it best to change front/rear sprockets at the same time. I haven't taken the guard off to inspect the front sprocket for wear yet. Also if anyone knows of good brands or ones to stay away from then some advice on that would be great as well.
