    Reba RL 29er losing air overnight

    Hey folks,

    I just got my new '13 Stumpy on Tuesday and the Reba RL fork is losing air-pressure overnight. Tuesday, and Wednesday night the pressure was set appropriately for my weight, and while riding I didn't notice anything at all. I used about 80-90% of the available travel on the trails so it was good while riding. The shop tightened up the schrader valve on the top of the air fork, to see if it would still leak before I rode yesterday, and it still does. I can ride the bike (for how many miles continuous, I don't know) but by morning it will have no/low pressure and bottom out just by sitting on the bike. I will be getting a new fork, under warranty early next week, so that's not a problem and I'm not even upset since I'll be able to ride in the meantime, and I live about a mile from my LBS.

    Has this been a common problem or did I just get unlucky? Just curious.

    Thanks.

    When my forks were new (Reba RL and Revelation RCT3), they both lost a good amount of air the first week or so of riding. Then they both settled down.

    I don't think it's supposed to lose ALL the air, though.

    The valve actually has two seals-- the one to the stanchion and the valve core(which could be loose).
    Put soapy water on both areas to look for bubbles.
    You can get another valve core at a tire store.

    Reba RL 29er losing air overnight

    One day I noticed that my new Reba RLT lost a bunch of pressure overnight. I pumped it up again and went for a ride. During the ride, I did a little jump and it blew out the wiper. Ended up breaking it down and replacing all the o rings. Pretty disappointed but at least they give you a rebuild kit when you buy the fork( maybe they know?). Been pretty solid since the rebuild though

    It's all good for me. I decided to not ride the bike in the meantime after feeling how much air pressure is lost. I went from 130 to 90 psi in about an hour of easy riding on a flowing, fast trail. I lost even more than that on a more technical trail with frequent "expert sections" of log piles, rock gardens etc. Thankfully the weekend rides have been with the wife, so I'm not pushing hard at all.
    I may grow old, but I will never grow up.
