The Omnium Trainer features an automatic resistance increase (IPR) that provides an authentic road feel and operates almost silently. The rollers are gentle on the tires, eliminating the need for a wheel change before racing. The resistance increases progressively, and the magnetic resistance unit is infinitely adjustable. The trainer comes fully assembled and is easy to fold. Weighing only 6.2 kg, this roller trainer is easy to transport (a carrying bag is included). When folded, its dimensions are just 66 x 18 x 20 cm. It is compatible with quick-release and thru-axles from 12-15 mm. The wheelbase and fork height are adjustable for different bikes (Road, MTB). Size: 26" - 29".
