Quick help when needed

On a recent Saturday I was using my Juggernaut off road and unfortunately caught a branch in my derailer and tore it up badly. I sent Biktrix support an email outlining my problem and included pictures. By 9 Monday morning Pacific time I had a reply and was able to order a new one that day. The new one arrived Wed. Wow, I was and am blown away. So happy with my bike and the responsive nature of Biktrix. I've even had the owner answer questions I had online. Who does that today?
