The Bombtrack Beyond 1 – Metallic Black is an adventure bike for riders who want to go far beyond paved roads and not worry about what the surface looks like. A 4130 double-butted crmo steel frame and fork, 27.5" wheels on sizes XS–S and 29" wheels on sizes M–XL, a Microshift Sword 2×10 drivetrain and TRP Spyre disc brakes: a tough, repairable package built for bikepacking, off-road touring and long days on dirt.
The geometry combines loaded stability with off-road control: long chainstays for tracking and traction, a taller head tube for comfort, and the Bombtrack Beyond travel bar (with strong flare) for multiple hand positions and better control off-road. It’s a drop-bar adventure bike that stays “lean”, yet is ready to handle distance, luggage and rough terrain.
Why It’s a Beyond 1
- Proven adventure geometry: stable under load, controlled on technical surfaces, comfortable over long distances.
- 4130 double-butted crmo frame and fork designed to absorb hits, vibrations and real-world abuse.
- Size-specific wheel setup: 27.5" on XS–S and 29" on M–XL to keep handling consistent across the size range.
- Off-road focused drop bar with wide flare for better leverage and control on rough descents.
- Plenty of mounts on frame and fork for racks, bottles, bags, lights and expedition setups.
Key Strengths
- Microshift Sword 2×10 drivetrain with 40/28T chainrings and 11–38T cassette: climbing-friendly gearing even with heavy loads.
- TRP Spyre C mechanical disc brakes: robust, easy to service and reliable even far from a workshop.
- WTB ST i23 tubeless-ready wheels and WTB Ranger 2.0" tyres: grip, comfort and control on gravel, dirt and light singletrack.
- Steel fork with triple mounts, rack mounts and internal dynamo routing: ideal for low-rider racks and front-load bikepacking.
- High system weight capacity (up to 140 kg) and MTB standards (BSA 73 mm, MTB ISO test) for long-term compatibility and durability.
Short Description
Beyond 1 is Bombtrack’s drop-bar adventure platform: a rigid steel bike built for long trips, rough dirt and flowing trails. A tough, serviceable chassis that mixes MTB components with a gravel cockpit, offering comfort, control and reliability almost anywhere on the map.
Ideal For
- Bikepacking and off-road touring on gravel roads, forest tracks and mixed terrain.
- Multi-day trips with bags, racks and significant luggage.
- Demanding gravel, light singletrack and remote doubletrack.
- Everyday use on broken roads, farm tracks and rough urban routes.
- Riders who want one bike to explore, travel and have fun off the beaten path.
Technical Highlights (Overview)
- Frame: 4130 double butted crmo, thru-axle, rack/fender mounts, internal light cable routing, 73 mm BSA BB shell.

- Brakes: TRP Spyre C mechanical disc, 180/160 mm rotors.
- Wheels: WTB ST i23 TCS 2.0 (27.5" XS–S / 29" M–XL), 32h, tubeless-ready.

Tyre Clearance (official)
- Frame – max without fenders:
XS–S: 27.5" × 2.1"
M–XL: 29" × 2.1"
- Fork – max without fenders:
XS–S: 27.5" × 2.1"
M–XL: 29" × 2.1"
Technical Interpretation
The Beyond 1 uses a split wheel concept to keep handling consistent across all sizes: 27.5" wheels on XS and S, 29" wheels on M to XL. Smaller sizes stay nimble and manageable, while larger sizes benefit from the roll-over and momentum of 29".
The 2.1" maximum clearance (frame and fork) places it between an extreme gravel bike and a rigid MTB tourer: you can fit serious off-road tyres without turning the bike into something cumbersome on tarmac.
The BSA 73 mm bottom bracket and MTB ISO testing make it easy to find compatible parts even during long trips, while the 15 mm front and 12 mm rear thru-axles ensure stiffness and steering precision with luggage and on technical sections.

¹ The size recommendation is meant as a general guideline to narrow down options based on rider height. Professional bike fitting considers additional body measurements and personal preferences. Since no two riders are exactly alike, these suggestions cannot be 100% accurate for everyone. The best way to confirm your ideal frame size is to contact your Bombtrack dealer (info@bikejamming.it) or a professional bike fitter, who can determine the most appropriate size for your needs.
