VO HOLLOWGRAM

The Vo series marks out our double-cam chainrings with Osymetric profile. Their distinctive variable-geometry shape lets you get through the dead spots faster, delivering a more effective and powerful push and bringing out a rounder, more productive pedal stroke, which translates into better traction and higher performance (laboratory tests on the Osymetric profile show that, compared with a traditional round chainring, you get an average 10% increase in power, a 12% reduction in lactic acid and less stress on the joints). N.B. For Vo chainrings to work correctly, choosing the appropriate offset is essential, as is careful adjustment of chain length and tension. We recommend checking all of these parameters before purchasing rather than relying solely on the standard configuration. If in doubt, our technical department is always at your disposal.
