The e*thirteen Grappler is a no-compromises gravity tire built for riders who spend more time pointing downhill than counting grams. Available in 29" and 27.5" x 2.5", it comes in two casing options and two compounds so you can dial in the exact setup your trails demand. The Flux GR Radial casing brings improved bump absorption and terrain conformity through radial ply construction, while the Flux AM casing keeps things lighter with a 90 TPI dual-ply build and Armor Weave sidewall protection for trail and all-mountain use.
On the compound side, MoPo is a pure 42a single compound designed for maximum grip, with a soft durometer and slow rebound that locks in traction in corners, under braking, and through the loose and ugly stuff. Momentum is the dual-compound option, pairing a firmer 50a center for better rolling efficiency with the same 42a MoPo rubber on the shoulders so you never give up cornering confidence. Reviewers at Mountain Bike Action and Vital MTB both called out the smooth transition from center knobs to side lugs as a standout feature, keeping grip consistent all the way through a corner.
Real-world testers praised the Grappler for punching well above its price point, calling out its consistent grip, solid puncture resistance, and sidewalls that stay supportive at low pressures without folding. Whether you run it front and rear or pair a MoPo up front with something faster rolling in the back, the Grappler earns its place on rowdy terrain.
Gravity-hungry enduro and DH riders get a tire that matches their aggression, with compound and casing combos that let you tune for your local conditions rather than settle for a one-size-fits-all approach. Your front end stays planted through loose, blown-out corners thanks to that 42a MoPo rubber, and the robust sidewalls keep you rolling even when you find the chunk. If you ride an e-MTB and need a tire that can handle the added torque and weight without crying about it, the Grappler has you covered there too.
