CLOSEOUT: Backbone Gen. 1 Wheelset, 27.5", Astral Stage 1 hubs

The original Backbone, this first generation wheelset hearkens back to 27.5's early days as snappy, xc-oriented mountain bike wheels designed to maximize the smaller wheel size's fast acceleration and quick spinning on climbs. While we have since replaced it with a burlier 32mm internal enduro-style counterpart, a handful of these OG offerings lingered in the warehouse. With today's emphasis on big, fast-rolling tires for gravel riding, the application for this light, quick, 30mm wheelset has again increased. Grab a set today at a killer price and use them as it suits you - be that a fast and lively mountain bike or a cushy gravel/adventure bike. 

All Astral wheels feature a Tubeless Easy rim profile for painless tire installation and are hand-built in Eugene Oregon by people that care.
