Hi, I bought a cheap 5 speed lead brick to ride about 20 years ago, six months after that I bought a custom built mountain bike with a 50-12 (112 inch) big gear on it, a year and a half later I had a custom hybrid frame built and dropped all the mountain equip on it. I still got it to this day. It is as strong as any steel bike can be, weighs 11kg. I still have it to this day and I love it to death but ! THE BIG BUT ! It is too heavy and too slow. My next bike which is now in the planning stages is going to light and fast, at 55 years of age I'm not going to compromise on anything. Why you may ask ? For the same reason people jump out of airplanes and not off chairs. Don't make the same mistake I did. Know your heart....
