Road Gravel Bikes: Where to Spend $160 to $699 on a Bike, Computer, and Saddle

Choosing a road or gravel bike setup means balancing a complete bike, a cycling computer, and a saddle. See how the Garmin Edge 840, Felt F30, Motobecane GRV Comp, and Selle San Marco compare.

Last updated Aug 17, 2026

Choosing a road gravel bike setup usually means juggling two questions: what kind of riding you actually do, and which part of the setup deserves your money first. A complete bike, a GPS computer, and a saddle all compete for the same budget, and the listed prices here span from $160 to $699. That's a $539 spread, so it pays to be clear about your priority before you spend.

Product Notes

Garmin Edge 840 GPS Cycling Computer

Garmin Edge 840 GPS Cycling Computer (Black

The Garmin Edge 840 is a wireless cycling computer that pairs with ANT+ sensors and is power-meter compatible, which makes it a natural fit for anyone training with data. Its compact body weighs just 2.8 ounces, and the included one-year manufacturer warranty adds a little reassurance, even though this is an Excellent - Refurbished unit. The plastic build keeps weight down, and the riding-time and alarm features are straightforward to use. If you already have a road or gravel bike and want to track your efforts without replacing the frame, this is the upgrade to make. The trade-off is condition: it's not a new-in-box product, so if you insist on pristine electronics, that's the catch.

Felt F30 Super light Red endurance Bike

Felt F30 Super light Red endurance Bike

The Felt F30 is a red endurance road bike with an ultralight aluminum frame, a carbon fiber fork, and upgrades that point toward comfort: front stem suspension, a rear elastomer seatpost, and padded handlebars. This is a used bike, so the condition is the main thing to weigh. The 25mm tires and added suspension make it more capable on rough city streets and light trails than a typical race-focused road bike, while the endurance geometry suits longer days in the saddle. It is not a gravel bike, though, and used bikes always come with previous-owner history. If you want a fast, comfortable road ride for mixed pavement and are okay with pre-owned, this Felt deserves a close look.

Motobecane Triple Diamond GRV Comp Women's Gravel Road Bicycle Shimano WTB

Motobecane Triple Diamond GRV Comp Women's Gravel Road Bicycle Shimano WTB

The Motobecane Triple Diamond GRV Comp is a new, women's-specific gravel road bike built around a 45cm frame, with drop bars, derailleur gears, an adjustable seat, and mechanical disc brakes. It is the only gravel-specific model in this group, which makes it the straightforward answer if you want a purpose-built bike for dirt roads and loose surfaces. The 45cm frame is described as fitting riders around 4'11" to 5'2", so it's aimed at shorter riders, not a one-size-fits-all machine. If that size range matches you and you prefer buying new, the seafoam-colored GRV Comp gives you a complete gravel bike without needing to assemble a parts list.

Selle San Marco 3D Printed Saddle Bike Seat Road Mountain

Selle San Marco 3D Printed Saddle Bike Seat Road Mountain

The Selle San Marco is a new, universal saddle with a 3D-printed structure and a racing-style profile. It weighs about 172 grams, which makes it a lightweight way to improve an existing road or mountain bike, and the breathable material is designed to keep things cool on longer rides. At 245 x 145mm, it fits a wide range of standard seat posts, and compatibility is listed as universal. Because it's a saddle rather than a bike, it works best as an upgrade, not a complete solution. The racing shape favors a forward riding position, so if you want a plush, upright cruiser seat, this is not that. But for performance-minded riders, it's a focused contact-point upgrade.

Final Recommendation by Use Case

If you need a complete, new gravel bike and fall within the 45cm size range, the Motobecane Triple Diamond GRV Comp is the pick. If you already own a bike and want to track power and ride metrics, the Garmin Edge 840 adds that ability for less than a new wheelset. If you're chasing comfort on a used road bike and ride mixed pavement, the Felt F30 offers a fast platform with suspension touches. And if your current saddle is the weak link, the Selle San Marco gives you a lightweight, breathable upgrade at the lower end of the price range.
