These tires came standard with my Creo 2 ebike. They roll smoothly enough on pavement, but emit a loud high-pitch hum that’s pretty annoying. I’m quite surprised that others are not noticing this— when I turn off the motor, the noise continues at the same volume, so it’s defy not motor noise.

I use the pathfinder as my main gravel tire but when I know I’m going to a loose surface like Phoenix I’ll put these on. Great fast traction. Tubeless I ride at 35/32 with tubes 40/36. 180lb rider with 700/42mm. Much more PSI than that your loosing performance/grip

The Specialized Tracer Pro provides supple ride especially at 70 PSI. Lower than 70 PSI diminishes performance somewhat. This is the 700 x 38 size and I have it mounted to a commuter rim with an internal rim width of 20 mm. Because of the very thick folding bead a 20 mm internal rim width or higher would behoove everyone to use. And use a Continental Hermetic inner tube. The extra support from a strong inner tube is in reality going to make a 2 Bliss ready tire perform better. This tire takes corner turns at high speed very well and with great control for anyone riding a chromoly Cyclocross bike frame. Enough said. Ron C

Great gravel tires as most of my miles have been on the hilly trails of Minnewaska state park and rail trails that are interconnect throughout this area.

Quiet, comfortable and grippy. So far so good (only been used a handful of times as yet).

I am using this as a front tire on my gravel bike. Performs well. No issues during install.

Great performing tire when the road/trail starts to get spicy. Minimal rotational weight. Definitely recommend for technical gravel/trail riding.

I rode a set of these tires for a year on my fixed gear gravel bike, held up to all my skids and poor line choices. That same pair ended up on my girlfriend's commuter build where they've been doing excellent in a myriad of conditions, and I expect they'll last a long time there as well

These came on my Crux. First thing I did was get rid of the tubes, put in tubeless valve stems, Orange seal 50ml in each. Held pressure well. They seem to stick well on off camber grass and tacky dirt, roll well on tarmac. Nice ride but would like to see them in a higher thread count

I have a set of these tires. I like the tread and soft rubber. Work great on pavement, dirt trail or light gravel. If the dirt turns to mud definitely not ideal. MY issue with these tires is that they leak from the sidewall. They simply do not work with tubeless set up. If you are using tubes then these are OK. Donnelly LAS gravel tires are superior.

700 x 47 on a Mavic A719 rim fit a 56cm Long Haul Trucker with just the right amount of clearance. Things would have to get a little bit ""custom"" to create a reliable fender install here though. Hope this size reference helps somebody. I am happy that this isn't another ""supple"" road tire. I wanted the highest volume ""mountain bike tire"" that would fit the LHT for loaded forest road touring. This is it. Sidewalls and tread still look brand new.

The low TPI pro version is my only complaint, they ride harsh. Hopefully at some point we get an S Works 120tpi like their mtb tires.

Rode these at the Lost and Found Gravel this past weekend 65 mile option. Was going to go with the Pathfinder but needed more grip for the course conditions so chose these instead. Ran them tubeless as this ride gets so many flats. The ride is 80 gravel 20 road, and these worked great. Fast on the roads and in the dirt. Plenty of grip on the climbs (inclines as steep as 22%), and total control on the downhills. Great tires for rides with more gravel than road.

I use this tire on my old Specialized Tricross ( a gravel bike before there was such a thing). The Trigger truly does it all...pavement, gravel roads, even some mellow single track. It's quiet and efficient on pavement and grippy in the dirt. No flats, knock on wood, in a season of mixed riding, including some rooty, rocky trails.

The new Tracer Pro has become my go to tire in grass and hardpack cyclocross races. It has so much grip in the grass. Just weight your bars, dig in your feet, the tires grips and the bike bends around the corner with a ton of confidence. I don't know what Gripton is, but it sure works. In hardpack, gravel or paved sections of the course the tire rolls fast and you can just lay down the power without wasting any watts. If you are looking for a tire that has a bit more grip than a file tread, but not as much knob as a intermediate tread, the Tracer Pro in the one for you.
