TR Line pistons, based on an adjustable resistance device, usher in nine positions that reduce or increase resistance levels so that the trainer can handcraft the circuit for the client target. Ever attentive to detail, TR`s piston carter ensures safety for users and people near the equipment. The solid, thick, silvergrey-colored frame is durable while elegant. Facilitating flexibility, each piece can be easily moved thanks to an integrated wheel system-optimising club space according to needs.
