Re: finally, a new project....
I'm not sure you WILL find any supporting material, just goin with my gut on this one and gonna say "I'll be just fine"
I know bearings are not commonly used, but I pretty much figured it was usually a price factor which made the decision or some attachment to "the way its always been".. as I've stated before using these on my skateboards as a kid has proven their durability to me! I've had these thing put up with dropping down very large sets of stairs, all the New Mexico dirt and dust, fights, and about 3-500 ollies a day....YEAH- THEY'RE THAT TOUGH, LIKE TONKA MADE!!
