BOMBTRACK Cale AL SX Eagle - Matt Black

The Bombtrack Cale AL SX Eagle is an aluminium hardtail built for riders who want to push hard on technical trails but also strap on bags and head out for off-road adventures. A 6061-T6 hydro-formed frame, RockShox 35 Gold RL 130 mm fork, Sram SX Eagle 12-speed drivetrain and KS dropper post as standard: a modern, aggressive and ready-for-anything package.

• 6061-T6 hydro-formed aluminium frame with Boost spacing, thru-axles, rack and fender mounts, and stealth routing for a dropper seatpost.
• RockShox 35 Gold RL fork, 130 mm travel with rebound adjustment and trail-focused support for fast, technical riding.
• Sram SX Eagle 1x12 drivetrain with 30 T chainring and 11–50 T cassette: a wide range for steep climbs and fast descents.
• Sram Level hydraulic disc brakes with G2 Cleansweep 180 / 160 mm rotors for powerful, consistent braking.
• WTB ST i29 29" rims with Kenda Hellcat Pro 29" x 2.4" tubeless ready tyres, ready for roots, rocks and rough trail surfaces.
• KS E20i dropper seatpost with 150 mm travel to lower your centre of gravity on descents at the push of a lever.
• Matt Black finish for a stealthy, clean and aggressively understated look.

Within the Cale family, the AL SX Eagle is the most trail-oriented option: it keeps Bombtrack’s adventure DNA, but adds a higher-end fork, 35 mm cockpit and Eagle 12-speed drivetrain for riders who are not afraid to ride hard on demanding terrain.

Performance & Ideal Terrain

With modern geometry, 130 mm of front travel and 29" wheels, the Cale AL SX Eagle is a hardtail that feels at home on demanding trail networks, alpine loops and fast off-road adventures, always offering a stable and precise ride feel.

On-road & off-road behaviour

• Climbing: the 30 / 11–50 T gear range gives you the low gears you need for steep ramps, while the aluminium frame keeps the bike responsive when you get on the gas.
• Descending & technical trails: the RockShox 35 Gold RL fork, 2.4" tyres and KS dropper post let you tackle steep chutes, rock gardens and tight singletrack with confidence.
• Transfers & mixed surfaces: the centred position and 29" wheels make it efficient on fire roads and fast gravel, yet still manageable on paved sections.

Best suited for

• Trail centres and all-mountain routes with technical sections.
• Alpine rides with long descents and rough terrain.
• Off-road bikepacking for riders who want a more “trail-ready” setup with a dropper post and aggressive tyres.
• “One bike for everything” use for riders mixing trail riding, gravel and rugged everyday riding.

Recommended setups

• Trail / All-Mountain: keep the Kenda Hellcat Pro 29" x 2.4" tyres set up tubeless at moderate to low pressures, pair the Bombtrack Illusion bar with the short Seido Drift stem to maximise control and confidence.
• Aggressive bikepacking: make use of the frame mounts for bags and lightweight racks, and consider a slightly faster rolling rear tyre if your routes include long stretches of hardpack and tarmac.
• All-weather / rugged commuting: add full fenders and a compatible rear rack; the 2.4" tyre volume brings comfort and grip on wet, broken or unpaved roads.

Independent Opinions & Technical Highlights

• A build featuring RockShox 35 Gold RL, Sram SX Eagle 12-speed and Sram Level brakes is widely regarded as a solid foundation for a modern trail hardtail, with a good balance of control, reliability and value.
• The combination of a 35 mm cockpit, 2.4" tyres and a long, stable geometry places the Cale AL SX Eagle firmly in the category of hardtails ready for demanding trails and sustained descents.
• The KS E20i dropper post is often seen as a real-world advantage rather than a luxury: a key feature to increase safety and fun on steep, tight or technical sections.
• The aluminium frame with rack and fender mounts keeps the Bombtrack adventure spirit alive, making this SX Eagle version suitable not only for “pure” trail riding but also for mountain touring or more aggressive bikepacking setups.

Bombtrack Cale AL SX Eagle – Size Guide

The size recommendations above are indicative guidelines based on rider height. Proper bike fitting is more complex and should also consider inseam, torso and arm length, flexibility and riding style.

Because no two riders are exactly the same, it is impossible to provide advice that will be 100% accurate for everyone. The best way to find your ideal size is to consult your Bombtrack dealer (info@bikejamming.it) or a professional bike fitter.
