A telescopic reel includes a telescopic supporting frame and a central module including at least one bracket constrained to the supporting frame and connectable to a bearing and guide through a fastener. The bearing and guide is adapted to bear and guide, during its rotary motion, at least one transversal intersection element of the reel. The bearing and guide is positioned on the at least one intersection element at a first distance from a longitudinal central shaft of the reel, the first distance being greater than or equal to a second distance between the central shaft and a crosspiece of the reel.
