The 47mm Pathfinder Pro will fit the Giant Revolt just fine with the flip chip in the standard position. This tire is the de facto gold standard for gravel.

This tire comes completely folded up like a piece of paper which makes it more difficult to install. As a result my tire has a flat spot on it which makes it wobble.

I chose the 38 size tires and they are perfect for my use. I found 40's were too large and 35’s too narrow. I have had other gravel tires that were too light and failed or too heavy. The Specialized is perfect for light to medium gravel and with the center strip perfect for the road. This tire is a perfect balance of tough and good tor the blacktop.

Easy to install tubeless, tires feel smooth on tarmac

Durable and reliable

I had the TLRs installed on my BMC Alpenlite commuter e-bike hardtail. I added Fox forks which makes it very comfy for gravel, trails or road. I can flip onto gravel from road without any problem. I use lower tire pressure for wet or snowy roads and single track and road and still have a great ride. They wear very well. Hard sidewall takes a lot of punishment from rocks, goatheads and other debris. This is definitely an all-weather tire

I ride 70% tarmac, 30% dirt. The center strip holds up very well to miles upon miles of asphalt. I got 3900 miles out of one set with a rotation after 2782 miles. I have gotten some punctures with these tires, but they might have sealed up if I had been more careful with adding/refreshing sealant. I have noticed that these tires can develop what looks like wet spots over time. This didn't seem to result in loss of pressure. Just for reference I currently have a set of Trigger Pro 2Bliss tires on my bike. The center strip of the rear tire wore to slick after 525 miles. They grip better than the pathfinders on some of the dirt terrain that I ride, but they just don't hold up to the asphalt. The pathfinders are great tires for me. The price is also good.

Coming from the mtb side with big tires and inserts, I installed the 47c version on my epic hardtail for an awesome "groadeo" bike. They roll smooth in the center, handled great when pushed into gravel corners and have impressive sidewall protection considering running them with fairly low pressure on some chunky CO gravel and washboards!

These are excellent tires for gravel!
