NEXT-LEVEL TRACK PERFORMANCE The Dolan DF4 builds upon the success of its predecessor, the game-changer that was the DF3. Having shattered world records and been the winner of over 80 World and European Championship races we’ve returned to the drawing board to dream it all up again.The DF4 has the same geometry as the DF3 but has been engineered for improved performance and handling. 115g lighter and 18% stiffer, we targetted those all-important areas in track cycling where the differences are really made. In a bike design streamlined for performance, in an aero design that’s UCI approved, the DF4 cuts through the air in the heat of competition.Trialled at the European Winter Six Day circuit, the DF4 has already won 3 European and 2 World Championships. And we at Dolan are proud to play a part in the track cycling revolution. WHO IS IT FOR? Those competing at the highest levels are often separated by the finest of margins. When it comes to performing at an elite level in track cycling, it often comes down to the equipment used. The DF4 was developed for those track cyclists who demand the very best in terms of performance and stiffness. The DF4 targets specific areas to eke out yet more performance over its predecessor. The stiff design ensures maximum power transfer through the pedals with negligible losses. While the lighter design ensures that every watt generated propels you forward ever-more efficiently as you reach the limits of what’s possible.
