    Adjusting shock pressure for heavier riders

    Does anyone have a hard time pumping their shocks to their correct psi?

    I have a pretty generic shock pump and I can't get it to pump past about 240, ideally need just another 10 psi. (shock is rated for up to 300)

    Any good shock pump recommendations, or tips on how to pump a shock to a high psi?

    Get a Fox Racing Shox HP shock pump. You can get them for around $30 online, but they feel like they should cost more than that. They're built surprisingly well, and can get a rear shock up to 300 psi without any problems.

    any of the shock company's shock pumps should have no problem getting you up to at least 300 psi. I have use a 4 major brands pumps and they all work great. also it shouldn't cost you any more than 30 bucks for one.

    I've never had a problem getting to 300 psi with the pumps included with fox and rock shox forks. It takes a while, but gets there.

    is it just taking too much force to pump more? Or is something leaking?

    Also note... just because the psi needle moves does not mean you are good to go. Make sure you screw the pump all the way in (made this mistake the first few times).

    Something else to also check with your new pump. With the three shock pumps I have when I remove it from the valve I always seem to loose a few psi. Check this with whichever pump you get and you might have to add a little extra to compensate for the loss.

    Adjusting shock pressure for heavier riders

    Thanks all for the advice, will try a new pump. With my current set up it just requires too much force. I'd try to compensate for a bit of a leak when I take the pump off but it doesn't really happen since I can't even reach the target psi.

    I have a hard time with my trail shock pump too. It's a Price Point version with the two stage head. It can get to 300 psi but requires a lot of force, sometimes leaks and sometimes is just awkward and I hit the bleed button by accident. Toward the end of 2011 I injured my shoulder and couldn't use that pump for more than about 100 psi. I have never had an air fork or shock leak on the trail, but I always carry that pump. I found something better for setting the pressures before a ride. Check out the Specialized UHP floor pump! I'm not affiliated and I know it sounds like spam, but that thing is awesome and way easier to get up to high pressure than the normal puny shock pumps.

    Specialized Airtool UHP. Should never have a problem with high pressures.
    Fat guys need bikes too.

    I have a Bontrager pump and have taken mine up to 260 without issue. It gets harder the higher you go though...
