I don’t have a lot

I don’t have a lot to compare it to, but wow! Super light, very responsive, and elegant. It just wants me to go fast and smash the terrain.

Update

After about 1,200 miles, I'm happier with this bike. I'm still not totally sold on the geometry, but I've grown more confident in the bike's performance with time. Pros: Light, fast and compliant. The AXS shifting is very good - not perfect, but very good. The shifting is crisp, and stays in adjustment, but the drivetrain is unforgiving of poor maintenance. Keep it clean and lubed or it'll be loud and cranky. The brakes are excellent - great modulation, and fantastic stopping power. With a spare set of wheels and "roadier" tires, there's no need for a road bike. The power seat is very comfortable, and keeps you firmly planted. This is an all-day comfortable, "do-everything" bike. Cons: Price and availability. Too slack a frame makes it feel numb compared to my old cyclocross bike, but I found that I eventually got used to it. The turn-in is not confidence-inspiring, and the handling is twitchy - it doesn't track well. Matte paint: looks cool, seems fragile.

Excellent Gravel bike and ended up replacing my road bike too

I am 6'4" 185 lbs, have been riding over 30 years, and purchased this bike thinking I was adding a bike, but after putting approx. 500 miles on it, about equal gravel and road, I sold my road bike. I am still running the stock tires and they are amazing as a mix of road tire and light gravel tire, they are fast and confidence inspiring on my trails. The seat is a home run, I'm now thinking of replacing the Fizik on my Mountain Bike with a Specialized Power Saddle. The frame is compliant enough for my demands, but strong enough for me to climb and sprint without flexing all over the place. The component mix is great and really only leaves me wanting to replace the handlebars with carbon to be a bit more compliant. As another reviewer stated the tall stack is really nice, keeps the bike comfortable by allowing you to remove spacers as needed to set your preferred bar height. This bike makes me want to go ride more, allowing dirt and road sections in a single ride.

Light and Fast

I’ve put about 400 miles on this bike, which replaced a Felt Cyclocross bike. It is indeed light, and I can find myself pushing it faster even when I’m gassed. The Rival group set functions well, and the ratios are well-spaced, although the top end is a bit short for road riding. The OEM stem seems a bit long, and even after swapping to a shorter stem and backing the seat, I feel like the weight is too biased to the front wheel. It’s a compliant set-up, and should function well as my “do-it-all” bike, I just wish it felt a bit more nimble. Time will tell if I grow to like as much as the old ride.

It's all about the stack!

No Future Shock necessary, the carbon frame, fork and seat post (along with wider tires run with low air pressure) soak up the bumps! This bike (2022 model) is simple, light, fast and smooth. I did replace the very capable Pathfinder Pros with 42mm Rhombus Pros only because the "gravel" roads in my area are poorly maintained, loose, slippery, and weather beaten rutted tracks that barely pass for roads at all. The overall deciding factor in purchasing this bike was that it had ample (35mm) spacers between the headset and the handelbar stem, plus I was able to install a shorter stem which was 2/3's the length of the stock one. When riding off the pavement, and when descending steep loose trails its better to be positioned further behind the front axle with more weight over the rear wheel, versus riding a bike with typical road geometry. If you don't need to haul around a lot of gear with racks and packs and such, get the Crux rather than the Diverge.
