Race XXX Lite Full Aero TTX

$179.99

Designed exclusively for Trek's Equinox TTX bikes, this extremely aerodynamic seatpost uses proprietary OCLV Carbon technology to keep weight low and strength high.

Symmetric design allows you to run either a 20mm rearward or 20mm forward offset, effectively changing your seat tube angle from a traditional 73 degrees to an aggressive 79 degrees.
