Frame Material
The Spire carbon uses premium Japanese Toray fiber using a unique latex coated EPS molding process to create tighter edge radius control using less material. The Spire alloy features a frame made from tough and dependable heat treated 6061 aluminum to strike the right balance of strength, durability and ride quality.

Pivot Technology
Collet main pivot technology improves rear end stiffness and keeps your pivot hardware tight. Additional bearing shields prevent main pivot bearing contamination when washing your bike or riding in wet conditions.

Frame Protection
We keep your bike rides quiet and your frame safe from damage with fully integrated, flush-mounted rubber frame protection at all critical areas. In addition to downtube and seatstay protection, the ribbed chainstay protector features expanded coverage of the rear dropout pivot area.

Geo Adjust Chip
Change the attitude of the bike with a simple flip of a chip. Our high and low settings give you two very usable geo settings to suite your riding style. Our high setting is comparable to most other companies low setting so there is a high shred warning in effect.

Size Specific Chainstays
The Spire has two size specific chainstay lengths to provide balanced handling and rider weight distribution across the range of sizes.

Enduro Max Bearings
