As the cliché suggests, never judge a book by its cover. Namesake and appearance alike, the DECOY MX and 29” are cut from the same cloth yet deliver two different on-trail experiences for real mountain bike enthusiasts looking to ditch the shuttle to the top and slash the most demanding terrain back down. Additionally, the new 720Wh battery is now available to everyone who just can’t get enough.

DECOY MX CORE 4 – Uncompromised descending dominance

YT Industries is a brand with its fingers firmly in the gravity pie. For riders looking for maximum amplitude, aggressiveness, and and roost worthy cornering characteristics– the DECOY MX fits the bill. The full carbon frame utilizes the V4L kinematic to drive 165mm of travel, enabling big bottom-out capabilities and heaps of traction. Up front, the Renthal Cockpit, ODI grips and SRAM Code RSC brakes direct the FOX 38 Float Factory fork, with 170mm travel controlled through an e-bike optimized GRIP2 VCC damper. Damping out back is handled by the FOX Factory Float X2 with four-way rebound and compression adjustability, ensuring all riders within the 150kg system weight can nail down their setup. YT’s 540Wh battery feeds the Shimano EP8 drive unit, which produces 85nm of torque within a svelte 2.6kg package, making it one of the lightest full power systems available. When it’s time to commit to the climb, Shimano’s Deore XT Hyperglide+ 12-speed groupset enables smooth shifting under load. The SDG Bel Air 3.0 saddle and YT Postman combination receive increased drop across the 5-size range, with up to 200mm for the XXL. For rapid acceleration and class-leading grip, the Crankbrothers Synthesis rims are paired with Industry Nine hubs and wrapped with the stickiest compound Maxxis Assegai up front and a DHR II out the back - both in EXO+ casings.

DECOY 29 CORE 4 – All-mountain adventure

If all-mountain epics, maintained trail flow and prolonged climbing efforts are a firm favorite, then the DECOY 29 will be right up your street. Akin to the MX version, the DECOY 29 CORE 4 receives the full carbon frame treatment. The V4L linkage provides a different, 29” specific kinematic this time around, and 145mm of rear travel damped by a FOX Float DPS Factory rear shock. The geometry reflects its climbing capability through a 77-degree seat angle and 458mm chainstay length, and is paired with the same powerful Shimano drive unit as it’s MX counterpart. The front end comprises of a 150mm FOX 36 Float Factory fork, including handy bleeder valves ensuring consistent performance at alpine altitudes. The Renthal cockpit features along with SRAM Code RSC brakes, a Shimano XT groupset, and a YT Postman seatpost, with increased drop heights. A Maxx Terra compound Maxxis DHF and DHR II combo balances fast rolling performance and climbing traction, complimenting the 29” front & rear tuned Crankbrothers Synthesis wheels.

720Wh Battery

Upping the ante of the DECOY platform, YT has developed a 720Wh aftermarket battery that equates to 30% more capacity than the stock 540Wh version. Off the shelf isn’t in YT’s vocabulary; the custom construction uses 21700 cells wrapped in a robust aluminum casing, mounted with two bolts accessible via a 5mm Allen key. This provides quick battery swaps and easy on and off-bike charging. Weight distribution and its effect on ride experience is a key consideration - the increased mass is kept close to the bottom bracket to retain the DECOY’s downhill capabilities. It's good news for previous, current, and future DECOY owners – the 720Wh battery is compatible with previous and current MX and 29 models in sizes M, L, XL & XXL.
