Re: Just ordered my kit
First of all hope all works out well for you on the purchase from gasbike.net.
Second: I think the old 70's 10 speed will be a good candidate for a build if you make sure the wheel spokes are very good and you put some high quality tires and tube with the deal, skinny tires dont take a hard hit like the wider tires do so I would keep that in mind and not hit serious bumps at high speed.
the older bike frame is probably better and stronger than many of the newer frame people are using so I think you should be good there.
Best wishes and get us some pics when you can.
I dont always ride WOT, but when I do..I do my best to keep the rubber side down..Ride safely my friends!
