TruShift Technology

Buttery Smooth

Folding bicycles, with their unique geometries, pose difficulties for front shifting. TruShift Technology optimizes the critical elements so you get nothing but smooth front shifting.

Custom Braze-On

Tern bicycles feature an offset bottom bracket. A custom-tooled braze-on positions the front derailleur optimally relative to the chainring for smooth front shifting.

Custom BB Spindle Length

Tern bicycles feature an oversized seat tube and require a custom spindle length for smooth shifting function. We’re fortunate that our friends at FSA are happy to make their top range MegaEVO spindles to our custom spec’s.

Pulley Position

TruShift Technology includes an optimized pulley position because lower friction equals lower shifting force.
