I would like to get into touring but I'm afraid my current bike wouldn't be up for the task. I'd ideally like to go on multiday unsupported (i.e. not staying at hotels) tours across the northeast. I currently own is a single speed with a fixed/free flip-flop hub.

I think that I could bring along additional cogs and freewheels combinations to suit the conditions. If I encounter hillier portions I either flip the rear wheel or make a complete change. I'm thinking I could possibly use the seat post as a lever to attach to a freewheel removal tool to save some weight. They make lightweight lockring removal tools AFAIK.

For a single speed setup I would think hills would be especially challenging so the issue of weight would be more important. I intend to go rackless using Revelate Designs saddle bag, a front bar bag, water bottle filled with tools and other heavy items, along with a jungle hammock and down quilt setup. I've done extensive ultralight backpacking so I have all the camping gear. I'm thinking I can come under 8 lbs without food and water.

I'm sort of rambling and thinking outloud here. What do you think of this idea?
