is 58mm 101a wheels good for street skate?
58mm is pretty big for street skating. Bigger wheels are usually used for vert because they are faster. I would recommend 52mm. 101a is fine for street skating. Its the hardness of the wheel and thats a really hard wheel. I like to ride a little softer but thats just my opinion. They are probably going to work ok though if you already have them and don't want to buy new ones, or something like that.
Cool them and help stop squealing in certain brake pads.
THE ONLY REASON WHY DISK BREAKS HAVE HOLES IS BECAUSE OF HEAT TRANSFER. THE HOLES FUNCTION AS A HEAT DISSIPATION. FRICTION IS PRODUCED WHEN THE BREAK PAD MADE CONTACT WITH THE DISK BREAK. IT HELPS COOL THE DISK BREAK, TO LET THE HEAT TRANSFER TO ATMOSPHERE! - MECHANICAL ENGINEERING ;)
Gives water a place to go which improves wet weather performance, better heat dissipation and lighter weight-those were the original reasons. However, I noticed that the latest BMW cars no longer have drilled rotors, don t know why.
