i hope not to ruffle any feathers here...
but is this what you mean?
for me, it is a two step process...
build the bike with the best parts and with keen atention to every detail (you covered.)
then build the power to match it.
much the way we built sprint cars 20 yrs ago.
i started with the largest frame i could find
with top notch suspension parts (had to be K2 EVO)
those are 8 inch hydrualic discs on 30mm front axel and 20mm rear
the bearings up front are greasless.
phase two will be power...
i will go slowly now,
my thoughts pull me in so many directions.
perhaps this forum may be the catalyst..
tell me how you would power this bike?
meanwhile.....
i am testing this "platform"
need to lear to walk before i run...
so far i have broken a crank,
had the disc bolts work loose,
and gone over the bars twice (at slow speeds, thank god.)
(hydraulic brakes on something this light, are very "touchy")
does it look like it matches the "qualifications"
i am seeing a quility helmet and leather britches in my future.
