I agree with the cable stop. When I have bought mine, there were no cable stop, and the owner used it with Vbrake, and with adhesive tape around the horizontal tube for fixing it, like Monkeeeeee01 did on his
.
Until 95 or 96, Kona should use the specific seat collar for the canti's. After, for V brake, just a cable stop was needed on the back of the horizontal tube.
I phoned yesterday to a Canadian friend who run for Kona in the beginning of 90. His kona heihei was 1991, the first one welded by sandvik, and had a classic cable stop. The "dog collar" appeared around 1992.
He told me that "BG" front was written on many kona, for "Bicycle group".
So, his bike would be the 24th 18" kona hei hei welded; so, a first one : 1992 or 1993…
And the decals are not the good one (Gil has sold me very amazing decals !)
