An 18" mid 80's MTB will make you look and feel like a monkey humping a coconut. At least that's how I felt. If you need any realistic or "built" measurements of any vintage MTB's, let me know. I purposefully scour the land for them. I am also the guy with the High Sierra in the classifieds section. Here's another I just picked up.

Mid 80's Kuwahara. Did a little mock-up tonight actually.



To me, the most important thing when choosing a vintage MTB is top tube length and head tube angle. I have had vintage MTB's with 22" seat tubes and 57cm top tubes. I've had vintage MTB's with 20" seat tubes and 57cm top tubes. Then there are the ones with 21" seat tubes and 59cm top tubes like the High Sierra I have. I thought it would work but I just decided the top tube length wasn't for me. Especially when I had so many other frames at my disposal.

Here's another that will be built when I have time to strip the raddy paint and clean up the rust.
