Astral

Outback 32" Alloy Rim

Astral Outback 32" Alloy Rim is built for long-distance riding on dirt, balancing durability and efficiency for lightweight XC mountain bikes and heavy-duty gravel builds. Its asymmetric profile is designed to even out spoke tension for a stronger, more stable wheel build—especially valuable when loads, terrain, and mileage stack up.

• Asymmetric rim design - Improves spoke tension balance by up to 30% for a more consistent, durable build
• Travel-ready alloy construction - Targets long-distance dirt use for XC MTB and gravel touring applications
• External nipples - Simplifies truing and service access without digging into the rim bed
• 23mm nipple depth - Supports secure nipple engagement for reliable wheel builds
• Tubeless-ready compatibility - Works with standard tires and can be set up tubeless with tubeless tape and a valve stem (sold separately)
• Build-critical measurements - ERD includes the slotted external nipple dimension; spoke bed diameter is 656.7mm
