so i got in 4 sets of the normal shape wheel from troy fingerboard.
the bearings on them are fast - all the craftsmanship is top notch. they all fit on with no issues and all of them roll smooth and are likely to last as the bearings are large in them - requiring the shim on the axle.
the only fault i can say is - they do not provide enough traction for my personal liking. that being said - they do however make a screech sound when you powerslide on paper. mostly because the machining tool marks are still on the wheel at first and will probably wear away with use after a bit. the contact area of the wheel to the surface is extremely small. that is probably why they are not so grippy to use - but a fantastic shaped wheel / fast and seemingly durable. .. with an un usual desing .
im verry happy to have them. thanks
