I had my LBS install my Q-Ring on my Catrike Road Friday. Rode my trike 50 miles on Saturday with a group of bents calling themselves the Foot First riders. Had a good time and got a chance to get the feel of the Q- ring. I only installed the middle ring. After 50 miles I think they help. My peddaling is smoother and I seem to get up the hills a little easier. Not that we have big hills in FL. I shifted between the middle ring and the large ring and after a while I perferred the middle ring. I may just go and order the big ring.
