Thanks for your support! The caveworks team will ship your order within 3-5 business days once your order has been received. An email including your order number and tracking information will follow.

Adding the RIVET of your choice to your cart is the most effective way to calculate shipping -- estimates are provided by our courier partners based on your shipping address. Don’t worry, these estimates are provided before you enter any payment information/complete a transaction, and caveworks does not save personal information you enter to check shipping costs.

Yes, the RIVET can be purchased outside of the U.S. however, please note that all orders will ship from the U.S. Accordingly, riders outside of the U.S. may expect to see higher shipping costs.

We continue to evaluate this, and hope to do so. This requires regional warehousing, which for a humble operation like ours is currently infeasible.

The RIVET will accommodate riders ranging from approximately 4’10” up to 6’6”. Bodies are unique, though, and proportions vary. Riders at the extreme ends of this height range should evaluate the RIVET’s geometry before purchasing and consider working with a bike fitter to be confident. Riders within this range but not at the extremes can expect that the RIVET will ably suit proportions of all kinds and adapt to a wide range of bike fits.

The caveworks saddle allows for approximately (+/-) 3cm of total adjustment. Should you choose to spec your own saddle, this amount may vary as different saddles may have different lengths of rail in their adjustment range. The RIVET is spec’d with a 30.9mm seatpost with a 20mm offset, so additional setback (+/-) can be achieved with low additional investment in an aftermarket seatpost appropriate to a rider’s needs.

Currently, single-speed and geared RIVETs are offered with 170mm,172.5mm, and 175mm cranks. A 165mm option will be available in late 2025. The caveworks team is working on sourcing a multi-length crank (subject to supplier arrangements that we are happy with and that preserve our emphasis on performance for good value). More to come on that in the future.

In our testing of 1x12spd drivetrains, we worked with 42t, 44t, 46t, and 48t chainrings. We found that anything less than 46t was likely to be insufficient at the top-end in "sim" mode (e.g., during hard efforts in groups, or sprinting for a segment in a group ride or for the finish line in a race). Further, while the 46t worked, it was arguably too spun out...right on the boundary of offering a quality experience for the stronger riders out there. We assessed that a 48t would solve that issue, and reasoned that it would work well on the lower end via simple adjustments to “trainer difficulty,” which corresponds to the degree to which a smart trainer’s resistance matches the real-world resistance for a given gradient. Essentially, “trainer difficulty” adjustments are analogous to gear ratio adjustments, allowing riders to toggle to their low-end needs to a suitabl range, and this is easy even with a 48t chainring. There is no real concern about using a chainring of this size when using ERG mode.

Please note: Our direct mount caveworks branded crankset is compatible with 3 bolt X-sync-style chainrings, so it can be swapped out to a different size if desired.

Yes, the seat tube is a standard diameter (34.9mm) and a common angle (74.5 degrees), so a front derailleur clamp can be installed.

The indoor riding enviroment can be extremely corrisive due to the amount of sweat a rider may produce while training.

Follow these simple preventative maintenance steps to keep your RIVET in peak condition!

• Sweat Removal: Wipe Down After Each Ride
  • Simply wipe down your RIVET after each workout to remove sweat residue.
• Component Protection: Clean and Grease Seat Post and Stem
  • Periodically remove and wipe down the seat post and stem assembly, grease can also be applied for added protection against corrosion.
• Chain Longevity:
  
  • Wipe down your chain after each ride and apply a wax-based chain lube to reduce noise and extend its lifespan.

The caveworks team believes in your right to repair. Note that parts are available from caveworks should you need any replacements.
