After my stock guide bent I went with this and have never been happier. seen on friend's bikes as well. Came highly recommended by friends that are woods riders and they all agree hands down this is the way to go.
I Recently replaced my stock unit with one of TM Design Works chain guide. I gotta say its worth its weight in gold. I do alot of tight trails and single track trails and its taken a fair amount of direct hits without phasing it. I recommend this to anyone looking for a much better upgrade from stock.
