I had a giant racing bike that was under $400 new, about 1986. The thing was great but I won’t take the kind of risk associated with riding it on the road now. I was concerned with flat tires at high speed on those skinny little rims. Now I have a Haro mountain bike, about $750 plus some good slick tires for the road and trainer. I regret that it has a “soft tail”. You lose a lot of energy on trails when the back end and front end spring are working.I can put a solid insert where the spring mechanism goes if I want.It seems to go out of tune-up easily not sure if that is normal for mountain bikes. You have to remember that some of the front and back gear combinations don’t work properly due to travel limitations of the derailleur.
