Trek Fuel Ex 7 review

It’s an impressive bike that challenges a number of age-old approaches to frame – and component - design. Lennard Zinn saw the technology first hand, reported on it here and has a more detailed impression in the latest issue of VeloNews, issue 13, due out July 9th. Following that tough act, Trek’s mountain-bike suspension designers, engineers and product managers unveiled a completely new version of the Fuel EX, as a side note to the Madone
