TGM skateboards in Michigan has a 4 dollar spacer kit + ship, that includes 4 longer spacers & 8 thin min. diameter washers.
The bearings on your tensioner are the same size as on skateboards ect.
The stock MM & Doodle bug ect. tensioners do ''not'' really have long enough spacers in them normally anyway,, which can put the bearings in a bind when tightened up.
The min. dia. washers in the TGM kit also just contact the inner races. of the ''outboard'' side of the bearings,, so the bearings won't potentially get pinched with the frame side spacer, & lock washer & ''or'' lock nut.
They work great, & I have them on all the bikes.
