BOMBTRACK Tempest Frameset - Storm Blue

The Bombtrack Tempest Frameset in Storm Blue is a modern steel road platform built around comfort, precision and all-day endurance. The lively feel of a steel frame is paired with a carbon fork for accurate steering and vibration damping—ideal for fast road riding with “all-road” tolerance when the route turns rougher than expected.

If you want a road-first frameset that stays confident on imperfect pavement and compact backroads, Tempest is a clean, practical base for a performance-oriented build.

Use cases

Road endurance with real-world comfort

Tempest is a road bike frameset at heart: responsive, efficient, and made for long days in the saddle. Steel brings smoothness and composure, while the carbon fork adds precision when the pace goes up.

All-road tolerance (within stated clearances)

With clearance for 700C × 35C tyres (frame and fork, without fenders), the Tempest can be tuned with more volume for rough tarmac, broken backroads and compact gravel—without losing its road character.

Light touring / daily practicality

Rack and fender mounts plus internal light cable routing make it a strong choice for a fast commuter or a light, minimal touring setup—still keeping the handling sharp and road-focused.
