Colorado-based indoor cycling company, Caveworks Inc., is announcing its new flagship product, the Rivet indoor-specific bike. Caveworks says that the Rivet is a direct competitor of the Zwift Ride. Two-and-a-half years in the making, the Rivet is a high-performance indoor cycling frameset capable of fitting riders of all sizes and is compatible with all thru-axle direct-drive smart trainers.
The Rivet comes nearly ready to ride. Just open the box, install the included handlebars, add your pedals, and mount the Rivet to the trainer. Caveworks wanted the Rivet to deliver value without sacrificing quality. Complete builds are spec’d with high-quality components carefully selected for indoor use.
The Rivet conforms to bicycle industry standards making it easy to swap parts. Its 12×142 rear spacing works with any thru-axle smart trainer. And, the 12×110 front axle means it works with front-end accessories, like the Wahoo Kickr Climb. It also sports a 68mm threaded bottom bracket and a 30.9 seatpost. This makes it easy for users to swap parts to their desired components, making it easier to replicate their outdoor bike’s feel.
The Rivet can be used as a bike fit adjustment tool as well. Riders can apply their outdoor bike measurements to the Rivet before exploring the impact of minor adjustments. Or, even test the fit of a bike before purchasing in a controlled setting with minimal tools and effort.
One-Size-Fits-Most
Rivet is one-size-fits-most. Its geometry is designed to make use of a 450mm, 30.9mm diameter seatpost and Caveworks proprietary adjustable stem which is essentially another seatpost that allows for a huge range of adjustment. It’s designed to cover a wide range of riding positions, including replicating fits for mountain bikes, endurance road bikes, gravel bikes, cyclocross bikes, TT bikes, and performance road bikes.
It can fit riders ranging from approximately 4’10” to 6’6″, meaning multiple users in a household can utilize a single Rivet. Below are some of Rivet’s geometry highlights:
- The Rivet replicates virtually any reach or saddle-to-handlebar drop, regardless of your handlebar preference.
- The Rivets geometry lengthens as rider height increases due to its forward-reaching headtube. This replicates the progression of top tube length from smaller to larger bicycle frames, ensuring that riders of most sizes will be able to apply their preferred stack and reach to the same Rivet.
- The Rivet’s seatpost angle offers a typical range of saddle setback that progresses appropriately over the range of adjustment.
- Because the Rivet uses an industry standard 30.9mm diameter seatpost, atypical saddle positions are achievable simply by swapping out the Caveworks seatpost for the 30.9mm seatpost of the rider’s choosing.
- Multiple riders in the same household can have their own saddle and seatpost that they can swap out quickly and easily on a single Rivet.
Rivet Weight and Footprint
The Rivet is made of steel that has been shaped to look good and ride good. The powder-coating gives the Rivet an industrial look as well as protects it from corrosion. Yet, despite its hardy look, the Rivet is claimed to weigh under 30lbs across all of the build options.
For those who need to move their indoor setup around, the Rivet’s light weight means less strain and effort when compared to smart bikes or other indoor bike frames. Plus, the Rivets have a smaller footprint when compared to smart bikes and outdoor bikes. This makes it a great choice for those with limited space.
Compared to Zwift Ride
According to Caveworks, the Rivet offers several advantages when compared to the Zwift Ride. For instance, “the RIVET prioritizes quality and durability (more metal, less plastic); it has standard component compatibility, offering unlimited configurations and serviceability; it is compatible with all thru-axle direct-drive smart trainers, as well as front-end accessories like the Wahoo Kickr Climb; it offers more flexible fit adjustability through the full range of adjustment; and it is much lighter while still delivering exceptional mechanical performance”.
Obviously, there are no Zwift Play controllers built into the Rivet, but for those that want to run them, the standard controllers can be strapped to the hoods. It seems that Zwift Play also has the edge with an optional tablet holder, but it seems like that would be something Caveworks could add in the future.
