I had no idea how head tube angle and trail could change how a bike handles until I switched bikes with a friend last night. It may also account for some difference in ride quality.

I was riding my Giant Sedona comfort bike and my friend has a Specialized low entry cruiser style bike. The steering on my Sedona, Which I believe is based on a mountain bike frame is so much more sensitive my friend almost had trouble keeping it straight. And I noticed immediately how more relaxed the handling of the cruiser bike was. I'm guessing these two bikes are at the extreme ends of spectrum for handling. I'm good with both bikes, but was shocked at the effect different fork geometry can have.

I do find my Sedona less then reassuring on the rare occasion i approach about 35 kph. It feels unstable. I don't know the numbers on these bikes fork geometry, but I can see clearly the Specialized fork extends farther then on my Sedona.

bty, I really enjoyed the Specialized low entry cruiser. I might consider one next time. It makes getting on and off the bike SO much easier, especially with a trunk bag or panniers.
