ok here's the rub. or the lack of it. this picture shows what i've done, but the darn thing keeps slipping on the spindle inside and it goes like molasas uphill in january. it's june. it's great on the flats. had it up to 25 on the speedometer. just dogs down going up hill. and not that big of a hill. any suggestions on how to make it faster? in 17.jpg you can see i have a rubber roller from a freeze plug for your car. it is one and 1/4 inch diameter. put inside the bmx bike peg and the whole things is tightened with a 3/8-24 nut. help???
