The 2025 Dissector keeps Troy Brosnan's fast-rolling signature tread and adds bigger, more stable side knobs for hard, rocky terrain. This 29 x 2.40 version combines next-generation MaxxTerra rubber with the tougher EXO+ casing on a tubeless-ready foldable bead.

Highlights

• Bigger, redesigned side knobs for grip on hard, rocky trails
• New MaxxTerra: Maxxis claims 30% more life, 15% more grip
• EXO+ casing with butyl bead insert
• Tubeless Ready (TR), E50 e-bike rated
• 1,045 g claimed weight

About the Dissector

Its redesigned side knobs have a larger footprint. The centre keeps the fast 2-3-2 layout but splits the middle knobs for better braking and terrain conformity, while the transition knobs sit further out for a smoother lean. Run it up front on a 130–140 mm trail bike, or as a fast rear on a 150 mm-plus bike in dry conditions.

MaxxTerra rubber and EXO+ casing

Next-generation MaxxTerra is an all-new formulation: Maxxis claims 30% more durability and 15% more traction than the original MaxxTerra, with no loss in rolling efficiency. EXO+ pairs a durable 60 TPI casing and EXO sidewalls with a small butyl bead insert that fends off pinch flats and rim damage.

Compatibility & fit

Fits 29-inch rims (ETRTO 61-622); Maxxis lists a 21–35 mm internal rim width. Maximum pressure is 50 psi. Check frame and fork clearance for a 2.40-inch tyre. Fitting isn't included; our workshop can mount it and set it up tubeless.
