Robert Axle Project 12mm Thru Axle Trainer – 175mm/183mm 1.0mm Thread

Robert Axle Project Thru-Axle Adapters
Upgrade your modern bike frame for seamless indoor trainer compatibility! Precision-machined from aerospace-grade 7075 aluminum alloy, these adapters bridge the gap between thru-axle equipped bicycles and popular trainers (1UP Fitness, Blackburn Tech Trainer, Cyclops VR Pro, Kinetic Flow, Tacx Neo 2T).

Key Features:
✅ Universal fitment for QR/quick-release frames via included adapters
✅ Hard anodized finish resists trainer clamp abrasion & corrosion
✅ Extended 15mm ends clear most frame stays & chainrings
✅ Tool-free installation with integrated 5mm hex access ports
✅ Tested to withstand 400+ lbs of trainer clamping force

Smart Fit Guarantee:
Before purchasing:
1. Measure your trainer’s maximum clamp width (typically 135-148mm)
2. Check rear hub spacing on your bike (142mm thru-axle standard)
Note: Adapter extend 15mm beyond frame width – ensure your trainer can accommodate this clearance
