In case you haven’t noticed, gravel riding is getting serious — and so is the equipment that goes with it. Bikes are more suited for gravel racing and no longer repurposed cyclocross frames. Unlike the gravel-aero-bar, gravel tires are something that will always improve ride quality. Ere Research hopes to bring performance to the gravel and adventure market with its full tire line, including a gravel race specific tubeless tire.
Ere Research comes from the mind of Piet van der Velde, who raced professionally in the 1990s before moving into product design and management, with a concentration on performance ergonomics. Hardcore saddle experts will remember his name from his time designing for Specialized, Selle Italia, and Selle San Marco saddles. More than likely, your current or former bike has a saddle designed at Piet’s workstation.
Ere’s Tenaci are designed around solid grip for riding gravel/dirt while maintaining a fast rolling centerline for pavement. The Tenaci is 700c only, 120 TPI, and is available in 30, 32, 36 (tested), and 40mm widths. The Tenaci retails at $89 for tubeless (with sealant and tubeless valves) or $70 for standard clinchers.
RoadBikeReview’s Ere Research tires arrived in a high-end presentation: A matte black box encasing the tire, a card explaining the tread, a tube of Stan’s No Tubes sealant and an alloy valve included. On the scale, the Tenaci tubeless weighed 406 grams. The tires are also noticeably sticky to the touch and the 65a compound offers a pliable, supple casing. Ere designs beyond just the racing application and it’s apparent thanks to the aramid bead-to-bead flat protection with a doubled layer just under the tread for extra puncture resistance, and reflective Ere logos all around.
Tubeless setup was easy. The Tenaci tires easily inflated with a floor pump. The tread itself is more flat than round and offers a large footprint on wider rims. Our Tenaci’s were mounted to FSA’s AGX gravel wheelset with a 21.5 mm internal width and felt great on an off-road. The first notable characteristic about the Tenaci is the grip, especially on deteriorating pavement with gravel overtop. Stopping traction is much appreciated when sliding down a logging road and unfamiliar territory in the Pennsylvania woods.
The grip is solid but not overpowering, as the center line file tread offers smooth rolling and grip over more massive rocks damp patches. The Tenaci offers non-slip grip on steep gravel climbs, keeping you grounded and moving forward. On singletrack the Tenaci is a rocket. Just make sure it’s dry singletrack. Like a file tread on steroids, the Tenaci flies on hard packed dirt and the tiny cornering knobs are just enough to keep you shredding. The Tenaci only suffered in soupy mud, but again this is a gravel tire and we wouldn’t expect it to perform in Euro-cross conditions.
However, the slow wear rate is what you would expect from a high performance tire. It wasn’t until around 500 miles into this test when I started to see the center line tread disappearing. That said, I’d recommend the Ere Research Tenaci to any rider looking for a performance advantage in the all road or gravel arena.
