Not to hijack the thread but I have a similar question. I own a 2004 Kona Shred which came with a bash gaurd in place of the largest chain ring and I have realized that for the type of riding I do I just simply don't need the bash gaurd and since about 75% of my riding is done on the road I would like to add the large ring back on. Anybody have any links to where I can get a decent 42 - 48 tooth ring for a reasonable price? Anything else I should know before adding one?
