hi eagle i beleave your pic but indeed i myself, can break those wheels like ones in picture in one bunny hop
my Cyclone is same model, diff PU, also my hubs are same material for now
there not that bad for scooters, your picture i want comment, indeed i have heaps pictures on my myspace of these same design of wheels broken
yet also video of me riding one on back

ive broken only 1 wheel like these 1 riding others yeah broken smashing the scooter not rolling or smashing it into cement yeah they break then
one wheel broken riding thats it, i do ride pritty big when testing them, example, the front wheel broken ALSO My scooter zone buff bars at same time image
will add more info later too busy & yeah i dont think comments above justifiy these wheels, ive got one one osame one on back when broken front & buffs of a treaded SR style fork

ive got the rear wheels still riding it going hard

the front broken 4 weeks back when snapped the buffs on landing & PU didnt break off we actualy did that after smashing it more so yeah thats honest result of above image eagle image sum are new & yeah i dont suggest these materials are to be used fresh anyway
