what brands of spur gears will fit the red aluminim spur gear adapter? i have the white robinsons spurs and black kimbrough spurs. will these fit without modifications? or are they too thick and will rub the belt and chassis sides? thanks for any info 
Trinity and Integy will fit. Both Robinson and Kimbrough will rub the white pulley.......Unless they both have come out with narrow gears in the last couple of months.
seamous- Are you racing this Saturday???
