The Vision NS modular crankset is a great way to squeeze more aero out of your tri rig without breaking the bank.

For far less than most other aero cranksets, this Vision NS Modular Compact Aero Crank aluminum setup is ultra stiff for excellent power transfer and uses a modular design to give a wide range of chainring options from 50-34 to 52-36. This BB386 bottom bracket compatible crankset weighs in at 869 grams and is available in lengths from 165mm to 175mm. The Vision NS is also compatible with Shimano 10/11, SRAM 10/11, and Campy 10.
