Start liking some of the bike brands on facebook and checking for their demo days. I went last weekend to the Downeyville classic mtb race and demo'd some Niner bikes. They let me clock in over 5 hrs of riding on the two bikes and over 35 miles. It's so awesome you just show up with a helmet fill out a demo form and get them your drivers license and your off, guy tells me to just be back before 5pm
So fast forward a week and after several emails negotiating parts and price, I just dropped more on a bunch of parts to build my new race rig then most ever spend on a ninjette
She'll looks something like this
I'll post pics of the build in a few weeks when it'd done
