The Bombtrack Tempest is a modern endurance bike for riders who want to combine the comfort of steel with the precision of a latest-generation road groupset. The 4130 double butted steel frame helps absorb vibrations and delivers a solid, natural ride feel, while the full carbon fork keeps the steering precise and responsive even at higher speeds.
The Shimano 105 2×12 drivetrain gives you a wide, well-spaced gear range, ideal both for long climbs and for holding speed on the flats. Tubeless-ready wheels with 700×32C tires complete the package, making the Tempest a perfect companion for granfondo rides, endurance road use, secondary roads, and rough asphalt sections.
If you are looking for a smart road bike, capable of supporting many hours in the saddle without becoming tiring, with options for fenders and real-world use 365 days a year, the Tempest is built for exactly this kind of riding: less stopwatch obsession, more riding pleasure, distance, and consistency.

¹ The bike size recommendation is intended as a rough guideline to help narrow down the options based on rider height. Bike fitting is a complex topic and also requires considering other measurements and factors. Since no two human bodies are perfectly identical, it is not possible to provide a 100% accurate recommendation for everyone. The best way to determine the correct size is to contact your Bombtrack dealer (info@bikejamming.it) or a professional bike fitter.
