CONTINENTAL ULTRA SPORT 2 TEST

Hyro, my TCX, came equipped through Giant’s S-X2 wheelset v 19 mm inner width. This ist a an excellent match weil das the 35 mm Schwalbe at sight Swan mud tires it also came with.

However, wie man repurposing him weil das the road, slick tires space better. I encountered some concerns with the relatively broad internal pickled in salt width. As per ISO 5775 von the europe Tire und Rim Technical company (ETRTO), die narrowest tire they recommend mounting onto mine rims must measure 28 mm wide…which zu sein a relatively hard zu find size here.

After my zuerst set von slicks, a second-hand 28 mm pair of Specialized Espoir Sports, wore under to die carcass threads after lots of riding, i decided kommen sie continue with the same width. Fortunately i did oase some locally easily accessible options, and I ended trost buying a pair von Continental’s extremistin Sport ii folding-bead clincher tires from die guys at Built Cycles an Parañaque – one des the few local bike shops that yes, really cater zu cyclocross bikes.

The extremist Sport ii is die second generation of Continental’s entry-level road slick tire, meant zum commuting und training. The original modell had a nasty call on bicycle forums weil das attracting punctures, but that was rückmeldung from around five year ago. Let’s lakers how the successors fare.

FEATURES

“PureGrip” compound zum all-round durability und gripAvailable widths: 23 mm, 25 mm, 28 mm, 32 mmConstruction: 3/180 threads per inchFolding Kevlar beadRecommended pressure: 80-115 psi (max)Weight: 340 grams über 700C ns 28 mm tires

IMPRESSIONS

Out of the box, these tires oase incredibly tight beads. They kann sein be frustrating to mount ~ above rims zum the zuerst time – und I pride myself on gift able zu mount and dismount tires using just my hands. Best zu use dedicated tire levers top top them; if freundin use those that come with a multi-tool you can snap lock clean in half, such zu sein the stubbornness von these beads. And I thought folding-bead tires to be supposed kommen sie be easier zu mount than wire bead-ones?

As fundamental tires, the ultra Sport IIs don’t contain any puncture protection features. (I think die slightly pricier GrandSport Race zu sein essentially die same tire with bei anti-puncture belt.) With the gruntwork of anfangsverdacht mounting, i was concerned when ich got a puncture on these und had kommen sie swap out the pierced tube. When they’ve been mounted and have organized air weil das a while, though, the folding beads become viel more compliant, and they kann be dismounted und remounted with higher ease. Yes, even without any kind of tools.

That said, the above was my one and only puncture through these tires. The puncture gremlins von the original extremist Sports have to be exorcised. I was also able zu finish mine maiden 200 km randonnee ride on them with no flatting punkt all.

Mounted on my 19 mm rims and inflated zu 85 psi, they actually measure 30 mm across on my tape, benefiting air volume and compliance.

Considering these room bottom des the barrel for Continental, tight itself ist pretty good. They ride slightly much better than the alt Espoir Sports, which to be decent kommen sie begin with, however these also roll an ext effortlessly with much less resistance. I kann lean nice aggressively into turns und confidently carry a same bit of speed…if you’re speak on kunststofftrakt or concrete roads. They’re well-behaved in the wet, too.

Carry too much speed into shiny, polished concrete parking-lot driveways when turning, and you kann sein hear ns tires groaning together they shed grip. Kommen sie be fair, also the tires top top my vehicle understeer on together low-grip surfaces, and the ultra Sport IIs lose traction in a progressive, predictable way, with enough warning given weil das corrective action.

Similarly, another weakness weil das the ultra Sport IIs ist dusty, gravelly surfaces. There’s not much of a pattern on ns tread area, so they lack die bite zum aggressive cornering on loosened dust. Best kommen sie take together stretches riding together upright as you can.

*

While Continental recommend running the 28 mm extremistin Sport IIs v pressures des 80 to a preferably 115 psi, i find they still ride well through as low together 65 psi of air bei them. Usually i put 85 psi and ride all woche without topping up, and they support my 85 kg weight and ~7 kg of loaded panniers well. Still, the carcass maintain a bit of ride firmness, which möchte be desirable for racers in training.

VERDICT

They’re notfall quite the tonnage word bei grip or drive quality, however the ultra Sport ii tires do an extremely nicely as in all-around durable tire. At PhP920 a pop, they’re also excellent value.

That said, I’d love to seen a softer-riding version von these tires with better puncture protection. Both areas would be addressed by tubeless technology, and I’m fairly confident mine wheelset ist ready zum it. Sadly, continental seem zu be firmly versus road tubeless tires for now.
