The Lab: Teravail Kessel enduro tire in review

If you often find yourself scared of ploughing into trees, you might want to reconsider your tire choice, and the portfolio of the US tire brand Teravail could have what you need. We put the Teravail Kessel Ultra Durable through its paces as part of a long-term review. Can the underdog disrupt the European tire market?

Teravail Kessel | Tester Peter & Simon | Test duration 5 months | Price € 89.99
Weight 1,273 g | Manufacturer’s website

Founded in 2015, Teravail are a US-based company offering eight different mountain bike tires. The Teravail Kessel on test is available as a 27.5 x 2.5″ version or a 29er, which is available in 2.4 or 2.6″ widths. Each of these gives you a choice of two different casing thicknesses and a Tan edition featuring light brown sidewalls and the lighter of the two casings.

The two different casings – Durable and Ultra Durable – both rely on a 60 TPI base with two nylon layers. The more robust Ultra Durable version relies on an additional 120 TPI layer and Apex inserts in the sidewalls. As such, it’s less likely to suffer a puncture or snakebite, which often happens when you’re running low tire pressures. The Teravail Kessel Ultra Durable tires on test weigh 1,273 g each and thus correspond to about the weight of a MAXXIS DHF DoubleDown or Schwalbe Magic Mary with the Super Gravity casing. For the rubber, Teravail leave you no choice but to go for the Grip Compound. Unfortunately, we couldn’t find exact details about the rubber hardness, but we’d say it’s on par with the MAXXIS MaxxGrip compound.

The most striking feature on the sidewall is the black-on-white Teravail logo. All other branding is kept very discreet.

On the trail, the 2.4″ Teravail Kessel performed excellently with its Grip Compound and Ultra Durable casing. It provides plenty of traction and grip on dry hard-packed ground as well as loose loamy surfaces and mud. If you push the tire to its limit, it feels predictable and controllable as it slides out, making it easy to get back on track. As such, it’s a good all-rounder and saves you from having to swap your tires around. We ran the tire at a similar pressure as we would with a MAXXIS DoubleDown or Schwalbe Super Gravity casing, which we were able to do without risking punctures or burping through the corners on our test rides. Nevertheless, it still provides feedback from the ground as well as sufficient rebound when jumping or popping off obstacles to support an active riding style.

Ultra Durable is the name given to the toughest casing in Teravail’s portfolio. With its Apex insert and dual fabric reinforcing, it offers plenty of puncture protection.
The tread pattern is like that of other manufacturers while offering a lot of grip on both wet and dry surfaces.

So far, we’ve had no flat tires on our extensive test rides on various trails and haven’t damaged our rims after slamming into roots and rocks. The excellent durability of the tire has proven itself over the last three months and it’s a good alternative to direct competitors such as the MAXXIS Minion DHF or Schwalbe Magic Mary. At the end of our test period, after putting the tire through its paces on very demanding trails, saving them no torture from hard braking, it doesn’t show any excessive wear and tear, proving to be very durable. Considering the key specs and the sturdy casing, the Teravail Kessel Ultra Durable performs excellently as a hard enduro tire.

If you dare to give the underdog in the tire business a chance, you won’t be disappointed: the tires offer lots of grip and excellent puncture protection. They’re very durable too. However, at almost € 90, you’ve got to reach deep into your pockets for the Ultra Durable version, though you can rest assured that the tires will last quite long.

About the author

Peter Walker

As editor-in-chief, Peter is as much a man of action as he is of words. This expert, screw-driver-flexing two wheeled-whizz has many envy-inducing characteristics, including a background in motocross, several EWS race plates to his name, and more than 150 recorded days at Whistler Bike Park. However complex the bike and however steep the trail, he’s probably already nailed it, twice. Oh, and he can do it all on skinny tyres too. When it comes to guiding consumers, Peter cut his teeth at Vancouver’s oldest bike shop and now puts pen to paper on the daily translating this know-how into our editorial plan. When not tearing up Stuttgart’s local trails while testing bikes, he loves nothing more than loading up his self-renovated VW T5 and hitting the road. The fact that he’s a trained paramedic gives his colleagues reassurance out on the trails. So far we haven’t had to call him by his alias ‘Sani Peter’, so here’s hoping he keeps it right side up for the rest of his time here!
