I ride on paved streets, sidewalks, and occasionally a trail. Is the NitroPro what I need?
mountain bikes. The nitrogen gas spring suspension absorbs cracks in sidewalks to massive potholes as you ride. NitroPro uses a progressive coil spring available in a softer street version or the standard off road version. If you change your riding style or just want to experiment, springs can be exchanged at no cost except for shipping (USD $3.00). Gas springs have a 90 day exchange policy. See below.
