Geax

Goma 26in TNT

The word "goma" in Spanish translates into "rubber" in English. Geax perhaps didn't intend us to think of its use of the word "rubber" for this tire the same way Mr. Dundee refers to his gigantic machete as a "knife," but that's what happens when a tire is this good. The Geax Goma TNT 26in tire is serious goma that brings massive capability to your bike.

The Goma's tread pulls out all the stops for an all-mountain tire. A super-sticky compound is formed into large, aggressive knobs that are siped and stepped for excellent mud-shedding and true high-speed tracking over both mild and highly technical terrain. Cornering is superb and progressive. Rolling resistance is low. Braking is right now. But what makes this tire so special is Geax's amazing TNT sidewall technology. TNT (for Tube-No-Tube) sidewalls maintain the durability of UST sidewalls while keeping weight in check (around 100g lighter than an equivalent UST tire), and the casing maintains the flexibility of a standard clincher, so ride quality is delectable. Also, speed can be kept higher over technical terrain because the tread can deflect around obstacles rather than bouncing over them and altering the course of the wheels' momentum. It weighs only 770 grams (2.25in version), but the Goma is easily burly enough for cased or off-camber landings, too — it'll take hit after hit and keep coming back.

The Geax Goma TNT 26in mountain bike tire comes with black sidewalls and in 2.25in and 2.4in sizes.
