FiR derailleur main image

This FiR derailleur was part of a mountain bike groupset that came in boxes carrying the words 'La Nuova Dimensione' (The New Dimension). For this reason the derailleur is often called the 'FiR La Nuova Dimensione'. But I think that 'La Nuova Dimensione' was more of a strapline and less of a model name.

This derailleur was manufactured by DNP of Taiwan. DNP marketed this model as the DNP Epoch 1. However the FiR version was markedly more attractively detailed, markedly better finished and markedly more expensive. It was one of the very first Taiwanese-made derailleurs to sell on quality rather than low-price.

I have seen photos of a road version of this derailleur with a shorter pulley cage. This would make perfect sense, as DNP also offered a shorter version of the DNP Epoch 1.
