well let me try to make a long story short as possible. my name is jason and i have a SDG speed mini. i was racing it and the rear rim failed. spokes pulled threw and the rim calapsed. i tired to contact SDG for a week strait. i left messages and no one would return my calls. SDG's rear hub has 32 spokes. everyone else like BBR and others use a 28 spoke rim and hub. so getting a new rim became almost impossible. i found out pitsterpro uses similiar wheels. so i contacted them and they actually answered the phone (unlike SDG), and treated me awesome. they sold and sent me out a wheel the same day. so i really wanted to say thanks to the guys at pitsterpro.com and if you have a similiar problems contact contact them and they will treat you right for sure.
