An improved 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/or guide through a fastener. The bearing and/or guide is adapted to bear and guide, during its rotary motion, at least one transversal intersection element of the reel； the bearing and/or guide being 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.
