    Lefty Carbon air loss?

    Just recently purchased a used {like new} 2003 Scalpel 3000, with the Lefty Carbon fork. The previous owner just had the fork recently re-built/serviced by Cannondale, and I received it with 0 miles on it. Having just recently added some air Ė about 150 psi, I noticed that within 2 hours the air pressure is down to 100 psi, and thatís just with the bike sitting still. Obviously, it leaks, which is pretty discouraging, especially since I have not even had an opportunity to ride the bike yet, and was hoping to do so tomorrow. Guess; Iíll have to forget the ride, or carry my shock pump for constant re-fuel. My question is how much does Cannondale charge for a fork service/re-build, and how long does this usually take, once I drop the bike off at my local shop?

    You probalbly know this but you do lose some air every time you check the pressure. Instead of checking the air pressure, check the sag. You likely do need a new o-ring, or if it's the air valve you can spray soapy water on it to see.

    Yeah; this goes beyond air loss from pressure check ...

    I just pushed down on the fork a few minutes ago - 10 hours later - and although I did not check the pressure, I bet that's it is only around 30 psi; in other words, it's soft as butter. Definitely have a major leak somewhere! I will check the valve area; but kinda doubt that its coming from there?

    It may be easy.

    The valve core may be loose or bad. I think they use a removeable valve core. If you have a bad seal, it is no big deal for any decent Cannondale shop.

    You said it was rebuilt and sold to you? Do you have the RA paperwork from the recent rebuild? Perhaps Cannodale can help. I might call them directly, explain the situation, and see what they say. They might have a way of tracking the work done.

    Hopefully its something as simple as that? I will contact the previous owner, and see if he has some paperwork on the work that Cannondale did. You would think that since it was just rebuilt, that they would honor their workmanship. Prior to doing so, I'll take it to my local Cannondale shop to have them take a look at it. When these forks do have to be sent in for rebuilt, does anyone know how much that generally runs, and what the turnaround time is? Thanks!

    turn around time varies. I've had it take about 2 weeks. but when I received a defective carbon lefty/elo fork and sent it back and paid an extra $25 rush request I got it back in 2 days!! just in time for my 24 hour race(had a spare though). could not believe it.

    Lefty Air Loss Update & Scalpel 3000 pic

    Well; I rode my Scalpel for the first time today. What an incredible ride! Most responsive bike I ever rode; and I have owned a number of nice mt bikes. I have never felt so comfortable/confident on a first ride with a new/used bike. My air loss problem is very real though; as I lose about 60 psi on a 30 minute run. Ironically; this worked almost perfect, as our local State Game area trail is divided into 4 aprox 2 mile sections; with the last section being the fastest & most technical, where a softer ride comes in handy. Talk about automatic variable travel! Regardless; itís no fun having to pump the shock after every run; so I'll be heading to my local shop this week. Hopefully, as suggested in previous posts, itís something that they can fix locally. If not, that $25.00 extra rush ship sounds like a good investment to me. Here is a pic of the bike:
