I rode a tiny portion of the Rainbow with HF a few years ago on our little bitty GasGas trials bikes and when he asked me what bike I thought would be good to ride the whole trail on, I asked him what is smaller and lighter than a trials bike?
Those 6" wide side-hill trails puckered me up good on my GasGas and I couldn't imagine riding it on anything bigger than that.
You are a crazy man, HighFive. Crazy in a good way, but still crazy.
Carry on . . .
