Blur XC. I find I need to put air in every few days as I seem to lose 20-30 lbs after a few days. I pump it up to about 190 and then a few days later it is down to about 150 or so. How long do these shocks hold air? Is this normal? If it is leaky, how does one get it fixed? Send back to Fox? Send to PUSH? Or can my LBS fix it? Thanks.
