What is the RIDER T1?

It’s a new, premium tire, designed to achieve optimized fit, superior function, and period-appropriate style on vintage, retro, classic, cult, and old school mountain bikes.

Is the RIDER T1 a reproduction?

No, it’s a me production. I closely studied many of the most popular mountain bike tire designs from the 1980s while designing the RIDER T1. You may discover hints of your personal favorites, but this is the tire that I would have designed in 1987, if I had been around since the beginning of our sport, and not just getting started in it at that time.

Who created the RIDER T1?

Terrance Kevin Malone, Founder and Managing Director of Terra One GmbH.

Where can I buy the RIDER T1?

Here on the Terra One website, as well as through a few, trusted organizations committed to spreading our passion for vintage mountain biking.

Mountainbike Museum, Arnhem, Netherlands –

Génération Mountainbike, Grenoble, France –

Chouchin Cycle, Tokyo, Japan –

dp Bike Garage, Seletan, Indonesia – @bikegarage.commuter on Instagram

Why should I use the RIDER T1?

To preserve MTB history, ride more frequently & build our community. After you’ve tracked down the vintage mountain bike of your dreams, don’t lock it away for another thirty years. Swap out the irreplaceable, original tires with RIDER T1s, get your treasure back on the trail, and inspire others to upcycle classic MTBs instead of recycling them.

Where did the name Terra One come from? What does it mean? What does it stand for?

Removing the middle of my legal name revealed the name of my brand: Terrance Malone, the individual, became Terra One, the company. We only have a single world to explore and enjoy: our earth, a.k.a. Terra One. Riding bicycles more often improves our own health, as well as that of the planet we’re fortunate enough to call home. Terra One products for vintage mountain bikes are designed to preserve history, build community, and allow us to ride our classics more frequently.


What colors are available?

Only one available at the moment: black tread with beige sidewalls.

Which sizes are available?

Only one available at the moment: 26 x 2.125″, legally known in Europe as 54-559.

A second Terra One tire design, in 26 x 2.0″ (50-559), is in development. Unfortunately, the boom in demand for bicycle tires caused by the COVID 19 pandemic will likely delay its availability until early 2021.

What does the RIDER T1 weigh?

The weight range of the RIDER T1 in production is 750g ± 40g.

For comparison, the 26 x 2.125 tire which was specified on one of the first, mass-produced mountain bikes, and shares its model name, was claimed to weigh 890 grams in an advertisement from 1985.

What puncture-protection features are used in the construction of the RIDER T1?

Aside from rubber tread blocks which are significantly taller than most modern tires, none.

I considered and tested two specifications with additional puncture protection, but initial feedback suggested that most preferred the RIDER T1 to be as light and efficient as possible.

Is the RIDER T1 available with a wire (non-folding) bead?


While folding bead mountain bike tires were extremely rare prior to 1987, I suspect fellow enthusiasts will overlook this period-inappropriate detail in the name of improved performance.

Also, while a version with a wire bead could cost significantly less, because it couldn’t be packed into as small a carton, it would cost significantly more to ship in small quantities due to dimensional weight calculations and oversized parcel surcharges.

Is the RIDER T1 tire position-specific?

No, but it is mildly directional.

While the first front and rear specific tire designs were available by the end of the 1980s, the initial designs didn’t yet fully deliver on that concept’s promise.

My design doubles up the direction of every third transitional tread block, so the tire creates additional lateral grip when oriented to the front and more driving traction when reversed for use in back.

Which rims are the RIDER T1 compatible with?

It has been designed for optimal fit and function with vintage, 26″, crochet-type rims.

The tighter tolerances required for proper tubeless function make many modern tires a very tight fit on many popular rims from the 80s & 90s. I designed the RIDER T1 for you to ride on as many of your classic bikes as possible, so I intentionally didn’t make them tubeless ready.


Which vintage tire models influenced the design of the RIDER T1?

I studied many tires while designing the RIDER T1, from motocross bikes where the original, off-road, two-wheeled tread patterns came from, through BMX, where they were adapted to bicycles, and finally to mountain bikes, where they were scaled up to 26″ diameter.

Key influences:

Mitsuboshi (later re-branded as Tioga) Comp II

National (later re-branded as Panaracer) knobby

IRC Racer X-1

The tire whose name inspired the Rumpstomper MTB races, held between 86 – 88 in Sonoma, CA

Fisher Fat Trax

Will the RIDER T1 fit between the chain stays / seat stays / fork blades of my bike?

The RIDER T1 measures slightly larger than the nominal 54-559 size would suggest.

The tires measure 57.5mm wide between the outer edges of opposite tread blocks, when inflated to 50 PSI / 3.5 bar, mounted on a rim with 25mm inner width.

If your rims are narrower (most are), and you run lower pressures (most do), then the tires are likely to measure between 55.0mm and 57.0mm in daily use.


Where is the RIDER T1 made?

In Thailand, where rubber is grown & harvested. Logistically and environmentally, it makes sense to build tires as close as possible to the source of the primary material used in their construction. Vee Tire Co. has produced tires from locally grown rubber in Samut Sakhon, Thailand since 1977. Their high level of vertical integration allows them to be more involved in the development process, produce tires more efficiently, and partner with passion-driven, low-volume customers like Terra One.

When can I expect the RIDER T1 to arrive?

Terra One tires are stocked in Switzerland, Norway, the EU, the UK and the USA. Customers in these regions should expect to receive their tires within a week to ten days after placing an order through this website.

Customers in Indonesia and Japan should order Terra One tires through our local partners in those countries. If you order through this website, the international shipping charges will be high, the wait long, and import duty may be due upon delivery.

Customers in other countries should expect two to three weeks delivery time. I am in discussions with potential partners in additional countries to stock Terra One tires locally, which should eventually reduce shipping charges, delivery times, and potential import duties.

Does the RIDER T1 have a warranty?

Terra One products are warrantied for a period of two years against manufacturer’s defects. However, wear & tear, as well as damage caused by improper assembly or abuse, are not covered.

What is Terra One's refund policy?

Refunds will be very carefully considered on a case-by-case basis.
