this is just a public thanks to Doug Heim for the excellent service he provided for me!!! i ordered a 72 tooth sprocket, shipping was super super fast!!! very quality part. everyone i showed the sprocket to was super impressed!!! and now that the 72 tooth is not gonna work out, Mr. Douglas is trading me for a 60 tooth, which is effin badass.... thanks a ton Doug!!!!!! If anyone is on the fence about buying from Doug, you would be stupid not to!!!
