Objective was to take tires, wheels derailleur and front fork from a 2005 Schwinn Rocket 3 donor bike which I bought for $5 at a swap and merge these parts to a Schwinn Heavy Duti frame from ind-chuckz. I'm very happy how this project has worked out. Very comfortable and solid ride. Feels great to bring 8 speeds and front suspension to this classic styled frame.

Thanks for the complements. Wanted to put stock chainguard back on but could not get a fastener in the front mounting in time - blocked by seat tube and solid sprocket. Then again kinda like the looks of that sprocket anyways!
