mine are as far back and down as Attack Performance rearsets can go, but I’m going to move them up just a bit now that I’m more use to them.
But, I’m 6’3” and 240 pounds, down from 270 pounds when I first set them up.
It’s really important to set the bike up so it’s as comfortable as possible FOR YOU right now, what’s comfortable will change over time as your riding and body does, try as much as possible to shape the bike to your body and how you are comfortable riding it instead of trying to change your body to fit the bike.
There are a lot of guys on here with way more experience than me, but one of the things I’ve learned, is that in about every way the body should lead the bike, the bike shouldn’t lead the body.
