The Regolith is a trail tire, known for its speed and grip is now available in a vast array of sizing options while delivering a large, versatile sweet spot. It's a workhorse tire delivering what riders need the most in the majority of their trail rides.

Sure, soft and gummy tires with huge, blocky knobs get all the attention but when for the trail rides that many folks tackle in their weekly rides, a balance between weight, speed, and grip is desirable. The Regolight is lightweight, it rolls fast while providing excellent cornering and braking traction on wet.

Sizing - the chart below illustrates the huge size range of the Regolith, from kids bikes to Plus bikes. Heck, they even have 26er!

New versatile tread design - Predictability is one of the most important traits in a trail tire as terrain and trail conditions change all the time, with little warning. Thus, grip and handling that is confidence-inspiring is key to the rider's safety and enjoyment. And when a few thousand feet of climbing is part of the routine, low rolling resistance and low weight are important considerations.

New dual tread compound - Fast-rolling center compound and good tacky shoulder compound is offered in two different casings - TR (Tubeless Race), SCT (Sealant Casing Technology - sidewall protection)

Kenda Regolith Pro

The new dual tread compound has a fast rolling center compound and good gripping shoulder compound.​

The Kenda Regolith Pro comes in three casings, the light and fast TR for race and XC, the SCT with sidewall protection for trail, and the burly EMC (electric mountain casing) for e-bikes. The EMC, which is tougher, heavier, and stouter, meets European certification for e-bikes. The U.S. doesn't yet have a counterpart standard, meaning that most mountain bike tires don't address the additional weight and performance needs of e-bikes. But Kenda will be ready if and when certification comes stateside.

The Regolith Pro's one-tire, three-flavor approach is meant to keep things simple. Kenda believes only a human spreadsheet could master all the tread patterns, TPIs, durometers, sidewall reinforcements, and other specs. Throughout its line, Kenda is maintaining consistent casing designations for ease of choice.

"We want simplification," said Roger Hernandez, Kenda marketing manager for MTB and BMX. "We have a versatile tread design with dual compound offered in two or three casings, and that's it."

The Kenda Regolith Pro's unique tread pattern strikes a balance between speed and traction with arrowed center and reinforced side knobs.​

Regolith Pro widths range from 2.2 to 2.6 in both 27.5 and 29er wheel sizes (a 2.8 also is planned for 27.5). Weights start at a svelte 650 grams and stay comparatively light throughout the range. Pricing will emphasize affordability - from $70 to $75 for XC, and $75 to $80 for gravity.

So what does Regolith Pro bring to the mountain bike tire party? The dual-compound is hard and fast-rolling down the middle and sticky and pliant on the shoulders - no surprises there. But the tread offers some clever tweaks. Middle knobs feature siping and arrowed patterns for low rolling resistance, but where Regolith Pro departs from the usual is in the side knobs. Yes, they're sticky and springy, but they also feature raised shoulder knobs with siping and a clever tie-bar matrix for stiffness and stability. The aim is to firm up cornering, keeping the knobs compliant for traction but strong enough to prevent folding over under pressure on the berms.

The tie bar connecting the shoulder knob and transition knob improves transition knob and shoulder knobs stiffness, which is important because Kenda is using a very soft compound on the most outward shoulder knob.​
