The C8-Pro has an aluminium profile and footbar and all new 8 PU wheel carriage system for the quietest and lowest maintenance ride available. The C8-Pro, like all Align-Pilates commercial reformers, has our Rapid Change (RC) spring bar for the simplest and speediest adjustment available. In the group class setting, where the C8-Pro excels, the RC spring bar of the C8-Pro radically alters the ease and speed of adjusting your reformer. The spring bar can be adjusted with attached springs with just one hand and one action, saving up to 12 additional steps when compared to most standard reformers. The most important factors that determine the ride characteristics of a reformer are the number and kind of wheels, which are taken into account by many Pilates professionals when choosing their machines. The number and type of wheels affect the carriage's resistance, the machine's noise level, how cross loading is handled, and how much maintenance is necessary for optimum performance. The C8 has eight wheels, which are intended to provide a quieter and softer ride with slightly more rolling resistance compared to the ride provided by the harder nylon wheels used in a four-wheel system, such as on the C2-Pro RC, where the wheels run in a matched aluminum profile.
