Help choosing first gravel bike. Giant revolt 2 (2024) for $1300 CAD or something else?

I’m looking to buy my first gravel bike and could use some advice.

I found a 2024 Giant Revolt 2 on Marketplace for $1300 CAD. The seller says it was only ridden once, and based on the condition of the chain and cassette, I believe them. They’re firm on price.

I’m planning to use the bike for rail trails, gravel/farm roads, and occasional pavement riding. I also want to use a smart trainer in the winter — I really missed the health benefits of cycling this past winter.

My question:
Would the Revolt 2 suit my needs, or should I wait for something else on the used market?

Other options I’m considering:
• Specialized Diverge E5 brand new from my local shop, priced below MSRP
• Decathlon Triban gravel bikes, currently on sale
• Canyon Grizl, though it’s more expensive than the others
• My local shops also carry Trek, Cannondale, Giant, and Surly, and so I’m open to exploring those too. There’s also Salsa and Marin but that one is an hour away.

I don’t mind going slightly over budget if the value is there long term. This is a big purchase for me, so I want to get it right.

Any thoughts or input would be really appreciated!
