Details
FAST. STABLE. CAPABLE.
The Collosus T is a new breed of all-mountain machine, built on a full ACX Carbon frameset with a stiff, one-piece rear triangle. Its solid linkage and 160/140 mm travel deliver exceptional rigidity and precise tracking. Hitting the sweet spot between all-mountain and enduro, it’s the natural upgrade for more capability without the weight.
ADAPTABLE IFS PLATFORM
The IFS Compact System uses a clevis-style linkage and ultra-wide pivot bearings for maximum stiffness and steering precision. Dual flip chips offer MX/29” compatibility and a high/low setting to tune geometry and progression. Refined kinematics enhance mid-stroke support and braking stability, giving the Collosus T a composed, confident feel that rides far beyond its 140 mm of travel.
RIDER-READY DETAILS
Every detail is designed for real riders. Integrated Poly-Pocket frame storage keeps essentials secure for pack-free adventures, while a UDH hanger future-proofs the frame for next-gen drivetrains. A threaded bottom bracket ensures reliable, hassle-free maintenance for years to come.
ULTIMATE VALUE
Built for riders stepping up to true all-mountain performance: the ACX carbon frame with IFS suspension delivers 140 mm of controlled, efficient rear travel, paired with a Marzocchi Z1 fork and Bomber Air shock for confident support on demanding trails. Shimano Deore 12-speed shifting, MT420 4-piston brakes, and Maxxis Dissector EXO+ tires round out a durable, trail-ready build.
