I just bought my first mountain bike after years of road biking. It's a Cannondale F-400, with a Super Fatty Head Shock. After two days of riding, the Head Shock leaked down. I pumped it back up to 150psig and the same thing happened after only an hour of riding. I took it back today, they checked it out and pumped it up again. Two miles later it's spongey again. Obviously, I have a leak.
I've had this bike for three days. Is the Head Shock by Cannondale reliable? I am not really sure they checked it thoroughly at the shop and I have to take it back again.
Also, I weigh 250 pounds. Am I too heavy for it?
Does anyone have any opinion/advice/commentary they can offer?
