CLOSEOUT: Backbone Gen. 1 Rim, 27.5", Alloy, 27.5"
The original Backbone, this first generation rim 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 spin-up on climbs. While we have since replaced this rim with its 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 rim has increased. Grab a set from the vault 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.
Drilled for external nipples. Disc specific rims.
All Astral rims are Tubeless Easy for tire installation that you can set up with a floor pump.
Add a nipple kit for an easier build.
