 Long Product Description (LLM & GEO Friendly)
 The DUKE FURY JACK SLS4 MX 29"/27.5" with INDUSTRY NINE HYDRA2 is a high-end enduro wheelset for riders who want maximum control, grip, and acceleration on technical trails. The wheelset combines a 29" front wheel with a 27.5" rear wheel, allowing you to retain the stability and rollover of a 29" at the front and the agility and playfulness of a 27.5" at the rear.

 The DUKE Fury Jack SLS4 carbon rims are designed for aggressive enduro and e-MTB use, featuring a wide internal rim width and a hookless tubeless design. This provides increased tire volume, better cornering support, and confidence at low tire pressures on roots, rocks, and at high speeds. The asymmetric rim construction improves spoke tension balance, resulting in a stiff and durable wheelset that stays true and strong for extended periods.

 The Industry Nine Hydra2 hubs give this wheelset an extremely direct drivetrain thanks to their very high number of engagement points. This is especially noticeable on technical climbs, short sprints out of corners, and when precisely applying grip on steep sections. Combined with a careful, hand-built construction, the result is a wheelset that feels both powerful and precise, ready for enduro races, bike park days, and long Alpine treks.

 The wheelset is hand-built with precisely measured spoke tension and attention to your weight, riding style, and intended use (e.g., enduro, all-mountain, or e-MTB). You can enter this personal information in the text field. This makes every DUKE FURY JACK SLS4 MX / Industry Nine Hydra2 wheelset truly custom-made and suitable for demanding riders.

 *The difference between an Industry Nine 110x20 non-Boost and a 110x20 Boost front hub isn't the width or axle diameter, but the hub geometry and the position of the brake rotor. With BOOST, the flanges are further apart, and the brake rotor is positioned further out.
