SRAM introduced the WiFLi rear derailleur as a solution to allow a rider to use upto a 32t cassette with ease. Previously it meant having to put a long cage derailleur on a bike, you'd need to put a longer chain on too. Simon is joined by Jason from SRAM who is the team liaison and finds out how products can be bettered for the professionals, this technology, when implemented, is available for consumer use too. Meaning that everyone can take advantage of advances in technology. Tony Martin is a classic example of a rider who wants to stay in the big chainring for as long as possible and with a 58t chainring paired up with a 32t sprocket on the cassette means that he can do so by using the WiFLi medium cage rear derailleur.
