TEMPEST AL

The Tempest AL is a lightweight aluminium allroad bike built for long days, fast commutes, and weekend escapes. Its adventure-ready geometry offers wide tire clearance and a dependable 2x drivetrain, striking the perfect balance between speed and versatility. The T47 bottom bracket adds durability and easy maintenance, while the Seido Banjo carbon fork features internal hub dynamo routing and front rack compatibility for loaded rides and night missions. Shimano’s hydraulic Tiagra 2x10 groupset delivers smooth, precise shifting with powerful braking. Rolling on Seido Sinus i21 tubeless-ready rims and fast-rolling Schwalbe One 700 x 30C tires, the Tempest AL handles mixed terrain with confidence. With Seido Tau disc hubs and 12 mm thru-axles for added stability, this is your go-to setup for allroad riding—efficient, capable, and ready to roam.

¹ Our bike size recommendation generally represents a rough guideline for quickly narrowing down the sizes from which to choose based on the body height. Bike fitting is a complex topic and other measurements and factors have to be accounted for as well. Since no two human bodys are exactly the same it is not possible to give a 100% correct advice for everyone. Therefore Bombtrack cannot guarantee for the stated recommendations to be correct for every individual customer. The best way to work out the correct size is to consult a local Bombtrack dealer or a professional bike fitter and have them determine the needed size.
