After a recent tweeking by my LBS guy, I have raised and moved my saddle. Still with the Max flite and really like it. I have a 1/4 inch leg length discrepancy that stumped my guy and he was unsure of my homemade washer wedges. I finally decided to try these wedges and WOW, glad I did. I wound up with 6 of them, measuring the same size as my heel lift given to me by my doc. My saddle issues with the left side rub are gone and I feel completely centered on the bike. SUPER cool I must say. Now I have no excuses!
