    Forearms going numb

    Long story short my forearms sometimes get tingly on the outer bottom like following the pinki back when bombing downhill. Just wondering if its cause of the vibration or something because it doesn't feel as bad as my hardtails vibration but I also dont go nearly as fast downhill and this doesn't happen.

    Relax your death grip on the bars, set up your levers properly, square away your cockpit and controls in general. Basic setup can be a big factor when it come to arm pump and fatigue. Also remember to relax between rough sections when you can.
    I'd rather have a bottle in front of me than a frontal lobotomy.

    I get the same tingly numbness every once in awhile while on the bike but more in everyday activies. Mine is attributed to pinched nerves in my back.
    There also has been times I have had numb arms/hands from the combination of my pressuer suit and riding bag being too tight. When I go for trail rides I adjust my back as I am not using body armor but then I forget to readjust when I get back on the dh rig.

    Mine tingle and sting its bad back (back injuries x4) and broken tail bone as well.... Saddle does it for me time to time.

    Best thing is adjust position like stated above grip and reach as well, all this helps...

    Yup forgot to mention that saddle position has done it also.

    Try ergon grips, they work for some people.

    all that, and get off the brakes....(brake harder and then stay off (off/on instead of slow dragging) and ride more

    All of the above and also when you are off the bike, sat watching tv, pretending to work... Get a squash ball and keep squeezing, I don't know how it works, but over time it helps!

    Perhaps check the angle of the bars too? I've noticed that my hands will have issues with certain angles. The outer parts will hurt if the bars are angled too far forward, and likewise the portion near my thumbs will hurt if they are too far back.

    It took me like 2 months of riding to get everything just *right* on my bike. Good luck!

    Lots of people were spot on with braking and bar ergonomics. It is also a strength issue. I spent a winter in a rock climbing gym a few years ago, arm issues went away.

    My fingers still ache after a full day, but moving around the brake levers and turning up the HSC reduced it a great deal.
    You have just been mentally Rick Roll'd. Yup you're thinking about it right now aren't you? Don't fight it.

    ergon grips, strength training and plush suspension.

    I did all 3 problems went.
    Why would I care about 150g of bike weight, I just ate 400g of cookies while reading this?

    Normally you get some tickling on your arms after a long descend.
    Vibration+shock = to muscle fatigue... it's normal.

    Normally numb hands are related to smashing the nerve (don't recall the name! Sorry) that goes from your arm to the hand.

    You can have a disc in your vertebra being in bad place... but normally that gives you numbness while your seating and not DH.

    Like all told:
    try the position... normally I see people using saddles pointing to high... or low nose.
    Brake levers that looks like they're not suppose...

    Personally, I have my saddle nose pointing a little down, in order to have a paralell to the ground while seated (saged).
    and the brake levers with the same angle has I have with my arms (parallel).
    post your improvements!

    Having the appropriate thickness grip is important as well. I've got big hands and I can not run small grips, my hand compresses too much and causes me pain. Also, as people mentioned, the position of your bar rotated forward/back makes a big difference as well as brake lever position both in/out on your bars and rotationally.

    Yep, once you get that bar angle right, you will know what stem you need. Get one of those grippers to build strength

    What I do before enduro MX point to point races and when i go ride resorts is hydrate big time a week before, like a 1.5 gallons a day, plays a big role in arm pump and blood flow. Also advil or alcohol thins your blood and lets it flow better to white knuckles/ tensed up arms.

    You sure Advil thins the blood? I know aspirin does but not sure about Advil.
    I used to know a girl who raced pro who'd take a 2 shots of vodka and 2 aspirin before her race run... yikes.

    the two nerves for numbness are your ulnar nerve for the little finger and ring finger and median nerve for the other two.

    You do not want to damage these nerves, trust me.

    I have a damaged ulnar nerve. The ulnar nerve is also known as funny bone. It feels like I have hit my funny bone, but for about 3 months now. Numb tingly ultra sensitive fingers pain in the arse.
    Not as bad as median nerve though.
    Common route of failure on that one is carpal tunnel syndrome, good by to using that arm for a few months.

    make your suspension more plush, vibration damages nerves and it is fking painful.
