It is not always necessary to replace the entire bike, sometimes you only need to update the group-set or change the frame to give some new life. A new frame can be the best solution to discover new horizons, or to improve comfort and performance of the bike, going from aluminium to carbon, or by varying the size of the classic 26" to modern 27.5" and 29 inches. All choices are valid, each one will deliver their own performances being it competition or for tourism, they all have the same goal in mind and that is to 100% satisfy the demands of the rider.
