i'm doing a sales demonstration in my class on the St. Martin Ringo Flat sprocket cause I've got a brand new one sitting around i can bring in. if anyone can provide me with pictures of them riding that sprocket... i'll use it in my presentation. i'll be making a power point so i'll also need as much info about it as i can gather, and anything compared to the competition... which i can probably make up, considering the huge industry were part off. so if anyone has nice pics of them tricking with that sprocket, post em.
thank you
