It’s just a little bit bigger, and that’s what cyclists are looking for. Schwalbe’s new Racing Ralph Mountain Bike tire is a full 29 inches in diameter.
“That size is starting to take off now,” said Jeff Clarkson, who works in customer service and technical support at Schwalbe. “Mountain bikers now are moving to the 29-inchers.”
Velocity has just introduced a 29-inch rim, so Clarkson might be onto something.
The Racing Ralph comes in two sizes-- 29 X 2.25 and 29 X 2.4. “And it’s a lightweight tire with semi-aggressive tread, so it rolls very fast,” Clarkson said.
He said the Racing Ralph proved to be instantly popular: “We brought in a couple hundred of each size about one month ago, and they sold out almost immediately.” Another shipment is due in mid-January, when the Ralphs will be back in full stock.

SCHWALBE MARATHONS – THEY KEEP YOU ROLLING
People who are tired of getting flats while cycling want a solution that works, without slowing them down. That’s what makes the Schwalbe Marathon Plus our most highly recommended tire: it’s tough, but it’s still fast.
Now the Marathon Plus has a lightweight brother, the Marathon Supreme, with a secret ingredient – from outer space!
The Marathon Supreme incorporates Vectran in its design. NASA was the first to use Vectran fibers; they were in the crash balloons that helped bring the Mars Lander to the surface of that planet.
“We’ve taken that material and turned it into a puncture-resistant material with a patented, highly dense weave,” said Jeff Clarkson, who works in Schwalbe Canada’s customer service and tech support, “so it’s very flat-resistant--just because of the material.”
The Marathon Supreme is lighter-weight and not as thick as the Marathon Plus, and it has another advantage: it’s a folding tire. “That way, you can take a spare with you,” Clarkson said.
Schwalbe Marathon tires are so durable, scientists at Schwalbe in Germany had to develop new test procedures in order to puncture them; just rolling the Marathon Plus over glass shards and thumbtacks (killers for most rubber tires) would not give researchers the flat they needed!
The Marathon Plus is made with a 5 mm-thick India rubber belt. India rubber is extremely flexible, so it curves away from most potential tire-busting sources – yet the same flexibility gives this material a low rolling resistance. Technicians in the Bohles laboratories, who developed the tire, have applied for a patent.
The true enemy of bicycle tires isn’t the broken bottle in the middle of the road; it’s the tiny bit of glass that becomes wedged in tire tread and is slowly but steadily driven into the inner tube by the rolling of the wheel. You can swerve around that broken bottle, but if you pick up even a small fragment of glass, your tire may go flat many miles down the road. But not with the Schwalbe Marathons.
The Marathons were designed with a tread pattern that resists picking up these tiny, sharp “time bombs.” So you’re protected from flats today, and tomorrow.
Now that’s the kind of technology that makes it likely you’ll never be stranded on the roadside with a flat tire again.
