BikeRide finds and shows you the best prices of the bikes you want to buy. Prices constantly change and it’s impossible to compare them all yourself.
We search for prices on over 120 bike retailers to guarantee that we find the lowest prices – to save you time and money.
It’s a promise we stand behind: If you find a lower price on a bike elsewhere, we will sell it to you for 10% less. For example, if you find a bike for $480 that we have listed at $500, we will offer you to buy it for $432 through BikeRide. The bike must be the same color and size, sold in the US and not include the use of a coupon.
If you find a lower price, email us at [email protected] with documentation of the price. We’re committed to making sure that the cost of a bike does not keep you from cycling!

Summary of Reviews
We have read all expert and user reviews on the Argonaut GR3. In summary, this is what cyclists think.
12 reasons to buy
- The GR3 is available in two Supernaut builds (SRAM Red XPLR or Shimano Di2 GRX/XTR) or Custom with bespoke geometry, layup, and component choices.
- The Supernaut comes in eight frame sizes with 505–605mm effective top tube lengths.
- Supernaut builds include free customization of stem length, bar width, seatpost setback, crank length, and gearing.
- Testers relish the pedaling efficiency, agile handling, and climbing ability provided by the super-stiff, super-short 415mm chainstays.
- The long, unusually slack 68.5° front end, steep seat tube, and short chain stays combine to inspire confidence descending at high speeds, even on messy singletrack.
- Reviewers savor how the frame provides comfort and compliance without slowing forward motion or dulling the responsive steering.
- Argonaut frames are made in Bend, Oregon.
- Argonaut engages in a conversation with every buyer to ensure the build suits their needs.
- At 17.2lb for an XL, the Supernaught (Shimano) is very light for a gravel bike... or even a road bike.
- Experts praise the GR3’s mouthwatering looks and beautiful finish, which is protected by a Cerakote ceramic coating.
- This bike has clearance for 50mm tires.
- The GR3 uses a round, 27.2mm seatpost, so a dropper or suspension post can be fitted.
6 reasons not to buy
- The GR3 is extremely pricey, although some experts deem the Custom version relatively good value.
- One expert complains of wheel flop at slow speeds. Another bemoans the “swimmy” steering when climbing.
- The super-slack front end gives the GR3 a sluggish feel when out of the saddle, especially on pavement or smooth gravel, according to a tester.
- Delivery times range from weeks (Supernaught) to months (Custom), though this isn’t unusual for bespoke, premium bikes.
- The in-house stem clamps the carbon steerer with only one bolt and proves finicky to tighten properly.
- One tester is unhappy with the road drop and unwanted flex of the ENVE handlebar.
Bottom line
Argonaut’s GR3 takes high-end gravel to even higher levels of personalization, performance, and price. Buyers can choose from two standard builds (Supernaught) or pay even more for bespoke geometry, layup, and specification (Custom). The GR3 wows reviewers with its low weight, pedaling efficiency, comfort, and ability to maintain high speeds on and off roads, even in terrains typically reserved for MTB. The only real complaint is the inevitable slow-speed sluggishness resulting from the slack front end, but testers agree the trade-off is worth it. The GR3 isn’t for slow pokes, bikepackers, or paupers. For everyone else, it’s pretty much perfect.
