The Kona LBF is a steel drop‑bar bike built for riders who want mountain‑bike capability with a more adventurous, upright cockpit. Inspired by the Pacific Northwest’s rough backroads and forest routes, it blends a 100 mm suspension fork, progressive geometry, and big‑volume 29er tires to handle everything from rugged trails to exploratory gravel missions.
LBF Highlights
- Reynolds 520 Butted Cromoly frame
- real-world capability, and the kind of durability that doesn’t flinch when things get wild. Custom bike builders worship steel for a reason: it rides better, lasts longer, and treats your body kinder on long days out.
- Rockshox SID 3P 100mm travel fork
- 100mm because it’s the sweet spot — enough travel for chaos, not so much that it dulls the fun. Oh, and it’s a fork you can actually get your hands on if you ever need parts.
- SRAM Apex Eagle lever w/ G2 4P calipers, hydraulic disc brakes
- Yep, this one’s custom. A fully legit, SRAM-authorized combo built specifically for Kona. A performance drop-bar lever finally meets a burly MTB brake caliper. It shouldn’t make this much sense, but it does.
- TransX RAD+ dropper post w/ DL butterfly lever
- Tried and true — the dropper that just works, even when conditions say it shouldn’t.
- Ritchey Beacon Comp handlebar w/ Comp Trail stem
- This combo is all about control, comfort, and stability when you’re adventuring into the unknown.
- Maxxis Dissector 29x2.4” fr / Forekaster 29x2.4” rr tires
- Fast where you want it, grippy where you need it.
- RaceFace ARC Asymmetric 27mm rims
- Strong. Simple as that. They’re light enough, tough enough, and ready for everything you’re going to throw at them.
- Fit Geometry is corrected for drop bars, optimizing posture for stability.
- Dialed specifically for drop-bar riding — the posture is stable, confident, and ready for long days or sketchy descents. No weird compromises, no Franken-geo. Just right.
- 67° HTA feels like a modern mountain bike
- Feels like a modern mountain bike because…it basically is.
- 75° STA (across all sizes)
- Keeps you centered, efficient, and powerful no matter the frame size.
- Sliding UDH dropouts
- Maximum adjustability, clean setup options, and future-proof compatibility.
