The Allen Adaptor Bar adds a top tube to non-conventional frames. Adapt ladies bikes and full suspension Mountain Bikes to fit on rear mounted racks. Internal spring maintains constant tension. Quickly attaches to wide range of frame styles. Plastic coated hooks protect your bicycles finish.
Rick’s Comment:
I have sold and installed a lot of these adapters to ladies bikes over the years. Simple, quick to add and they work well. This is one of the least expensive Car Rack Frame adapters currently on the market.
