My road bike gets a little unstable feeling at higher speeds during downhill runs... starts around 30-35+ MPH. The gyro effect from the front wheel is not increasing enough to over come "the shakes". Tire pressure, front/rear alignment, front hub play, headset play, fork rake and trail... anything else to consider? It bugs me to see mountain bikers on the same roads doing 40+ comfortably! Your thoughts?
