Yes Pat I agree that CCC has not only a fine springer shock but also a terrific build ongoing. This forum has really come to life again with 10 are so active, quality builds represented in the last month or so...really exciting.
You say archaic Pat & I say your shock is cool & obviously it works or you wouldn't be allowed to run the salt. Your right rodder's been using friction shocks/dampers for 7 decades at least. Don't have a shock towers & don't need like them, go scissors. T's , A's you name 'em especially running no fenders or cycle tins, friction shocks were the go to rebound and they've been back in vogue for some time.
Weight & speed factor into almost every area of a build design, fasteners & welding, material strength, brakes, tires etc. It makes a long list & suspension is in the mix. My Simplex is in that "taint" category. Taint real heavy & taint light neither. Same could be said about the speed. So as I refine. I will modify or replace any existing part which doesn't measure up. Tires, wheels, brakes drive chains etc. I ride what I build so eventually ugly flaws will come up like weeds after the rain & then be disposed of in order.
Third oil change yesterday, relatively little debris in any of them. Transmission is finally settling in and neutral is actually a location that can be found rather easily. Has always started well (when adequately grounded) & cranking up is really effortless. Pedal side has finally broken in and is much easier to power by leg now, but still not without effort.
