Assembling the unit is simple!
Unfold the trainer's frame, attach the resistance knob bracket with the 4 screws, attach the fluid resistance unit with the bolt, exchange the enclosed rear wheel skewer with the one from your bike, loosen the lock rings and knobs on the trainer, line up your rear wheel with the couplings on the trainer, tighten the couplings, be sure the tension knob is fitted into the barrel bolt on the resistance unit, tighten against your rear tire, put the riser block under your front wheel, and get to riding!
