I'm new here and I also started skateboarding like a month ago. I bought new wheels and bearings. The new bearings are Shiver Abec 9. So I put them on yesterday and today I went to ride for a bit. When I came back home I freespined the wheels and the front ones are quite louder than the back ones. I just wonder why that is, beacause they are all the same bearings and wheels. I tightened them down the same way, and the bearings have built in spacers, so they are really nice.

So why are two wheels louder than the back wheels? Also I think the back wheels roll faster than the forward ones.
