The Microshift Advent MX 1x10Sp 3 Piece Groupset 11-48T is an incredibly reliable, wide-range drivetrain upgrade designed for mountain bikers, trail riders, and e-bike users who value simplicity over unnecessary complexity. Stripping away the fragility of modern 12-speed systems, this robust three-piece bundle provides a massive 11-48T gear range while utilising a wider, more durable 10-speed chain. Engineered to thrive on rough Australian singletrack and punchy climbs, the platform is lightweight, incredibly easy to adjust, and built to withstand the elements without demanding costly proprietary hub standards.
The heart of the groupset is the beautifully engineered Advent MX G-Series 10-speed cassette. It features bi-directional shift ramps that smoothly guide the chain up and down the cogs, delivering predictable, immediate gear changes even under heavy pedalling loads. To eliminate unnecessary weight, the large 48T climbing gear is mounted to an aluminium spider carrier, keeping the total cassette weight remarkably competitive while protecting aluminium freehub bodies from gouging. Because it mounts straight onto standard HG freehub splines, it breathes high-performance life into your current wheelset without a total hub replacement.
Controlling the action is the responsive Trail Trigger Pro shifter and the rock-solid Advent MX rear derailleur. The derailleur utilises a horizontal parallelogram architecture that isolates shifting movement from vertical trail chatter, keeping the chain firmly tracking across the gears over technical rock gardens. This is paired with an adjustable ratchet-and-pawl clutch mechanism that eliminates chain slap and can be switched off for effortless rear wheel removal. At the handlebar, the shifter features premium internal bearings for a light lever throw, distinct indexing clicks, and an integrated silicone traction pad to give you slip-free control in wet, muddy conditions.
Wide 11-48T Range: Provides all the necessary low-range crawling gears for steep climbs and high-speed cogs for fast fire-trail descents.
Ratchet-and-Pawl Clutch: Delivers exceptional chain retention and dampens noise over rough singletrack, featuring a convenient on/off switch.
Aluminium Spider Carrier: The largest climbing cogs are secured to a lightweight alloy spider to reduce rotational weight and prevent freehub body damage.
Silicone Shifter Grip: The Trail Trigger Pro lower lever is equipped with an integrated silicone traction pad for slip-free shifting in wet weather.
Standard Freehub Fitment: Fully compatible with ubiquitous Shimano HG freehub bodies, saving you from purchasing expensive, proprietary axle standards.

Ultra-Reliable 1x Simplicity: Perfect for shedding the weight and complexity of an old front derailleur while gaining a modern, secure single-chainring system.
Lightweight Performance: At an aggregate system weight of roughly 857g, it actually weighs less than several premium 12-speed configurations on the market.
Mud and Slush Friendly: The wider spacing of a 10-speed cassette provides significantly more room for clearing mud and grit compared to tightly packed 12-speed setups.
Cost-Effective Maintenence: Uses affordable, robust 10-speed chains and individually serviceable components, keeping your long-term running costs low.
No Hub Upgrades Required: Fits perfectly onto standard mountain bike wheels without forcing you to buy premium Microspline or XD freehub bodies.
❌ No Crankset or Chain: This is a 3-piece upgrade kit containing the cassette, shifter, and derailleur; you must supply a 1x crankset and a 10-speed chain separately.
❌ Larger Cadence Jumps: With an average gear jump of roughly 17.8%, riders who are highly sensitive to small changes in pedalling cadence may prefer a tightly spaced 11 or 12-speed system.
❌ Closed Eco-System: The unique, precise cable-pull actuation means you cannot mix and match this derailleur or shifter with standard Shimano or SRAM 10-speed components.
When installing the rear derailleur, pay close attention to the cable routing around the integrated redirection pulley. This pulley is Microshift's secret weapon for removing friction and keeping the lever action light and crisp. To maintain that flawless shifting, ensure your outer housing has a clean, smooth loop into the pulley without any tight kinks, and always use standard 4mm linear shift housing rather than brake housing to prevent unwanted internal flex!
