The Astral Backbone is a bomber 32mm internal 27.5 trail mountain bike rim. Astral has improved the stiffness, strength and longevity of this rim by using an asymmetric rim design than improves spoke tension balance by up to 30%. On the trail, this translates to balanced handling you can rely on. With a 32mm internal width it’s perfect for wide trail tires.
We primarily build with Sapim spokes and nipples made in Belgium.
- The Sapim CX-Ray (~4g/spoke — $3.80) is our top end option and offers not only the best performance and ride quality but also the most durability. It has the longest fatigue life and is guaranteed to make every wheel build feel more alive and vibrant through the hands while also managing to dull unwanted road buzz. Their incredible low weight and vertical compliance may come at a price, but they have the tendency to turn otherwise good builds into seriously special ones. Excellent for virtually every application.
- The Sapim CX-Sprint (~5.5g/spoke — $2.70) is the mid range performance spoke on offer. They still offer low weight and agreeable flex, but are a higher effective gauge and provide more substantial lateral and torsional stiffness. Very strong, fast, spokes that are an absolute joy for us to work with as builders. We can always guarantee a well balanced and predictable build with these.
- The Sapim Race (~5.8g/spoke — $1.30) is our standard double butted option. Its 2.0mm at each end 1.8mm in the center to reduce weight and improve ride quality. They’re light, strong, and are an excellent choice for just about every application from carbon road wheels to heavy-duty commuters.
