cheap mtn bike. <$100 new. knobby loud tires. barely rolls on pavement. if you put on nice smooth tread tires, would bike glide better? or do you need to step up to better hubs/bearings/lighter rims as well to improve performance?
Give it away and get a real bike. "Performance" doesn't belong in the same sentence with any description of such a bike. I'm not being a snob, that's just the reality. You can only get so much for $100, and performance isn't on the list.
i already knew the answer when i typed it. kids bike. we got it 6yrs ago? but even a POS will roll ok with nice wheels/tires? in a straight line? a 35lb bike frame will hold the wheels just the same as a 15lb CF bike. technically that is.
Kee-rist, what a bunch of snobs. If the guy could afford a $1000 bike, he would have bought one. I rode for 25 years, up to 8,000 miles a year, on a succession of bikes the most expensive of which cost $350. The average was probably $175 or so. I did my first century on a sub-$300 mountain bike with $6 slick tires on it. Now that I can afford better, I HAVE better, including an Atlantis and Rambouillet, which I love, but they aren't any more fun than the cheapies. Lighten up.
For the OP: Skinnier, higher-pressure tires will make a big difference. The bike will still be sort of a junker, but it will be a faster junker than it was. Ride it and enjoy it.
i loaned out my bike to kid #1 who lives 200 miles away for the summer. i am shopping for a different style bike now and was just playing around with the cheapo mtn bike. kid #2 now says she wants it at her apartment. she probably won't ride it much.
