HOTCHECK S-Grade Titanium SRAM UDH Derailleur Hanger

Precision Without Compromise.

A precision-engineered titanium derailleur hanger. Supplied with matching titanium UDH mounting hardware.

The HOTCHECK S-Grade Titanium SRAM UDH Derailleur Hanger brings together exceptional craftsmanship, advanced manufacturing and an uncompromising approach to materials.

Far removed from a conventional replacement hanger, this meticulously engineered component embodies HOTCHECK's belief that even the smallest mechanical details deserve extraordinary attention.

Manufactured from HOTCHECK S-Grade Titanium Alloy, with material originating from BAOTI Group and sourced through specialist suppliers in Baoji, China, the hanger features an intricately sculpted profile, precisely defined surfaces and exceptional attention to finishing.

Produced using 4-axis CNC machining, its distinctive geometry reflects a deliberate balance between mechanical functionality, dimensional accuracy and visual refinement.

Behind the complex machining lies an equally considered manufacturing philosophy. HOTCHECK specifies dimensional tolerances as tight as ±0.01 mm for assembly-critical features, carefully managing cumulative tolerances to maintain consistency across production batches.

Supplied with a matching titanium UDH fixing bolt and washer, the complete hanger and mounting assembly weighs just 33.0 g.

For riders who appreciate the difference between a component that simply fulfils its purpose and one that elevates the entire build.

Performance is the baseline. Aesthetics is the obsession.
