Im about to begin my second mb build. my first bike was an "80" cc happy time on a huffy cranbrook, and while it was good as far as a first build, i'm stepping it up for this second one. I just purchased an Electra Cruiser 7d, another 80 cc happytime, a shift kit and a few other odds and ends. Now, im trying to figure out what i can do as far as adding some form of suspension. as far as i've found, there is not a whole lot of selection out there when it comes to 1in threaded suspension forks. so in my research i came across this: Converts conventional threaded headsets to us 1 1/8" threadless stems....S&H $5.95 or $2.95 >> DESCRIPTION: ... Alloy threadless adapter. ... Converts conventional threaded headset to use stem for 1 1/8" threadless. ... Has removable shim so it will fit 1" or 1 1/8" fork steerer, BUT MAY NOT FIT ALL OF THEM, SO PLEASE MEASURE TO BE SURE. The diameter of the bottom part that goes into the fork steerer is 22.2mm without the shim and is 25.4mm with the shim on it. is this all i need to run a newer 1-1/8 fork? or will i have to find a fork and take it to a machine shop and have it machined to a 1 inch tube. now if this is the route i take, will i still be able to use the original headset, or will i have to find a new one. sorry for all the newb questions. thanks for any insight!
