You did not make a mistake if this is your first mountain bike. The geometry appears to be identical so the difference is probably weight and material. Just ride and beat the crap out of it. One of my friends rides a Specialized Hardrock which is Specializes low end bike. There is no way a high end XC frame would have survived the way he rides.Tamu8104 said:I'm just bought my first mountain bike, a C-dale F400 and I was noticing that the frame for the F600 is different. Can anybody tell me what the difference between the Furio and the Furio-X frames are? Is there any difference in weight? Did I make a mistake and should have paid the extra for an F600?
