So my pump has been off. It turns out that before a race a couple weeks ago I was checking my air pressure with a buddies new pump. I realized that I had been riding and racing with 20psi for a couple years now. yikes! I went ahead and raced that afternoon with 20. Didn't want to change anything the day of the race.

I run stan's with nanoraptors, the regular kind.

Do you guys think the extra low pressure could be slowing me down? I know I can corner really well, but maybe it's more sluggish going on the smooth stuff?

I've never had burp problems on my bike or had the tire roll off the rim. I have had burps on the SS tho when using eclipse.

Should I keep riding the 20psi or bump it up to 30?

I weigh 150.

If it's not broke, don't fix it.

I imagine you'd go faster on the flats with 30 but you'd be sacrificing traction. I guess it depends on what's more important to you.

What's stopping you from just incrementally increasing your pressure say by 2psi and seeing how that treats you? You'd learn a lot more doing that than anything else IMO.

The bike will sure ride smoother with 20psi in them. Adjust in small increments on a variety of terrian to find out where your sweet spot really is.

Get yourself a Zefal pressure gauge. I've never found the gauge on floor pumps to be accurate, it usually reads too low. With the Zefal gauge you'll be able to use anybody's pump and just ignore the built-in gauge.

If your tire pressure was truly too low you would notice your tire squirming and losing grip around corners, and every time you went over logs and big rocks you would feel the rim hitting. If that's not happening, you're probably using enough pressure.

I usually pump mine up to 30-35 and I weigh 180. I also go by the squeeze the tire guage

I know my tire pressure is too low when Im doing turns and feeling the tire fold.
I always ran lower pressure then my friends they insist higher is better
