The hyper 7 pro is the old Pro model. There have been a couple of variations on the pro over the years depending on where you live or when you bought it. The TQ pro is the latest. The PCR pro is the Paul coleman racing version. This has PBS steering instead of C-hub and a lot of the bits are not compatible with the others (TQ, Pro, TQ pro etc).
They are all good but if I was buying now I'd probably get a TQ pro.
