Nothing More is Needed. Nothing Less Will Do.

The Surly Preamble is a hard-boiled steel commuter built for comfort, durability, and buffoonery on pavement and gravel.

The challenge was thus: Build a serious steel bike and give it only the attributes that matter most. Make it quick and comfortable on pavement, as well as confident and compliant on degraded surfaces. What the Enginerds put forth is Preamble, a pavement and gravel utility worker that proves you don’t need to cut corners or clip coupons to make a more affordable steel bike. You just need to keep it simple.
