The Universal Derailleur Hanger (UDH) has solved many problems. If you’ve ever had a cycling weekend cut short due to a bent or broken derailleur hanger and not been able to find a replacement, you know what I’m talking about.
The UDH eventually gave way to SRAM’s direct-mount derailleurs, both electronic and mechanical. However, these direct-mount derailleurs posed challenges for some indoor trainers, often requiring users to fiddle with tricky adapters or ditch them altogether.
But, not anymore! Well, hopefully. While this new thru axle from Saris still technically falls in the “adapter” category, it seems pretty easy to use.
Saris says, “As more bikes adopt the Universal Derailleur Hanger (UDH) system, riders need a trainer solution that keeps up. Our new thru axles deliver exactly that: a modern, secure, and universal connection for Road, Gravel, and MTB bikes on Saris wheel-on trainers and most major wheel-on systems.”
Each adapter kit includes a thru axle adapter with both 1.00 and 1.75 thread pitches. The kit comes with spacers, end caps, a UDH spacer, and 40mm hex bolts. It also includes a shorter bolt-action tube to replace the longer one currently in the trainer.
Saris offers 142mm x 12mm thru-axle adapter kits for road and gravel bikes, as well as 148mm x 12mm thru-axle adapter kits for mountain bikes. A 148mm x 12mm adapter with a 1.50 thread pitch is also available. All retail for $59.99.
