BOMBTRACK Cale GX Eagle - Metallic Burgundy

The Bombtrack Cale GX Eagle is the steel version of the Cale platform: a modern hardtail built to push you deeper into the backcountry while still feeling fast and fun on your local trails. A double-butted 4130 crmo frame, RockShox Revelation RC 130 mm fork, Sram GX Eagle 12-speed drivetrain and KS dropper post all come together in a bike that’s ready for technical singletrack, alpine loops and loaded overnighters.

• 4130 double-butted crmo steel frame with Boost spacing, thru-axles, rack and fender mounts, and stealth routing for a dropper seatpost.
• RockShox Revelation RC, 130 mm travel for more control and adjustability when trails get rough and fast.
• Sram GX Eagle 1x12 drivetrain with a 30 T chainring and 10–52 T cassette – huge range for steep loaded climbs and fast transitions.
• Sram Guide RE hydraulic disc brakes with Centerline 200 / 180 mm rotors for powerful, modulated braking on long descents.
• WTB ST i29 29" rims with Maxxis Ardent 29" x 2.4" tubeless ready tyres – fast rolling, with enough bite for mixed terrain.
• KS E20i dropper post with 150 mm of travel so you can get the saddle out of the way at the press of a lever.
• Metallic Burgundy paint that highlights the steel tubeset with a deep, premium finish.

Within the Cale family, the GX Eagle is the benchmark steel trail bike: a stable, precise and adventure-ready hardtail designed for riders who want one bike to cover everything from demanding trail riding to multi-day off-road trips.

Performance & Ideal Terrain

The Cale GX Eagle is a steel trail hardtail at heart: long and stable with a compact rear end, giving you confidence at speed and agility when the trail tightens up. The 130 mm fork and 29" wheels make it a natural fit for technical trails, big mountain rides and ambitious bikepacking routes.

How it rides on and off-road

• Climbing: the 30 / 10–52 T gear range lets you spin up steep gradients, even with bags on the bike, while the steel frame smooths out trail chatter.
• Descending: a slack head angle, Revelation RC fork and 2.4" tyres give you grip and control through rock gardens, roots and fast corners.
• Mixed terrain: 29" wheels and the Ardent’s rolling profile keep you moving quickly on forest roads, doubletrack and the inevitable bits of tarmac between trails.

Best for

• Trail centres and all-mountain riding with technical sections and long descents.
• Alpine routes with varied terrain, from smooth forest loam to rocky ridges.
• Off-road bikepacking if you want a comfortable, durable steel frame with plenty of mounts.
• “One bike” setups mixing trail riding, chunky gravel and rugged everyday use.

Recommended setups

• Trail / All-Mountain: run the Maxxis Ardent 29" x 2.4" tubeless at moderate to low pressures, keep the Bombtrack Illusion 35 mm bar and short Seido Drift stem for maximum control and stability when things get steep.
• Adventure & bikepacking: use the frame and fork mounts for extra bottle cages and bags, add a light rear rack if needed, and consider a slightly faster-rolling rear tyre if your routes include long hardpack or gravel sections.
• All-weather / rugged commuting: fit compatible fenders and a rear rack; the 2.4" tyres deliver comfort and grip on wet, broken or unpaved roads.

Bombtrack Cale GX Eagle – Size Guide

These height-based size suggestions are general guidelines to help you narrow down the options. A proper fit also depends on your inseam, torso and arm length, flexibility and riding style.

Because no two riders are exactly the same, there’s no recommendation that will be 100% accurate for everyone. The most reliable way to choose your size is to combine these guidelines with a more detailed look at your measurements or, if needed, a professional bike fit.
