We are not a bike store; we are a specialist bicycle repair house, we do everything that the suburban bike shop does, and everything that they can not do as well, all the too hard problems end up being sent to us to get sorted out. Aldo has designed and made his own all carbon fibre bicycle fork (Concept Z) which have been successfully fitted to his own and other frames.
