How rad is this? Back when mountain bikes were “allowed” to race cross, J.P. Weigle took to the course with his self-made bike. This was in 1986, hence the hairnet and other components from the period. Here’s what Weigle has to say about it:
“The rules allowed mountain bikes back then, and some of us were very competitive against the classic cross machines, those rider’s were upset when we did well.
I raced at 110% effort and pretty much collapsed at the end of each race.”
