How to install your Bones erasers:
Bones, originally, it is the brand of wheels of Powell & Peralta, it has developed for a few years its own identity and a real range of wheels divided into several programs: STF (Street Tech Formula) for street / SPF (Skate Park Formula) a softer hair to have more grip on the ultra smooth surfaces of Skate parks / ATF (All Terrain Formula) soft wheels perfect for cruizers and very difficult terrain. Here too the team is up to the task with among others: David Gravette, Adam Dyet, Ben Raybourn, Taylor Bingaman, Jordan Hoffart, Chris Haslam, Chad Bartie, etc ...
There are several hardnesses of rubber for skateboard trucks: soft, medium and hard. The trucks are originally mounted with medium gums. If you ride very tight, replacing your tires with hard ones is a good calculation, so you will get the setting you want without crushing your tires and damaging the threads of your King Pin. Likewise, if you ride really loose, go for soft gums.
