Bbmoozer,Stor,Alright Hybrid riders!My hybrid Diamondback Ambition was my first love.6 years of trouble free riding,6 events ridden in comfort.Weighs 30lb though so I really got a work out.As for speed,I don't really see a big jump since I went to a 25lb roadbike.I know many think 25lb is still heavy but 5lb off the bike and 5lb off me hasn't changed my average speed any.When I rode the HillyHundred last year,I thought I was in trouble when almost everyone was on a roadbike.Then I saw people that were way into their golden years,people that had to weigh 300 pounds,and a couple on handpowered cycles cranking their way over those hills,and I knew I could do it.Thats my best advice.Be comfortable as you can and draw energy from those around ya.I wish I had the wind to talk to others when I ride.I'm lucky if I can let out a gasp when confronted with a monster hill ...KC
