Featuring everything that makes the caveworks RIVET the most useful and best-performing indoor machine available: suitable for any geometry; easy, continuous adjustments to dial in fit; built to industry standards so you can swap in parts of your choice; and mechanical performance that delivers every watt to your smart trainer. No more transition adjustments for the outdoor bike, no more outdoor drivetrain contaminants, and no more expensive parts that play no role in your indoor training. One frame works for multiple riders. The geared RIVET is equipped with 1x12 Shimano GRX, ideal for those already running 12-speed-compatible smart trainers. Together with dialing in your trainer difficulty settings, this 1x12 can offer every gear you need for training and racing without sacrificing smooth steps between gears.
