SILCA's owner and chief designer, Josh Poetner, was formerly
technical director at Zipp, the legendary carbon wheel company. His
ability to think outside the box and find inspired, creative
technical solutions continues with the innovative SpeedBalance
What is it?
SpeedBalance is the world's first Aerodynamic Wheel Magnet AND
tunable balancing system for high performance cycling.
SpeedBalance replaces your spoke magnet with a rim mounted
aerodynamic magnet that can save up to 1 watt at 30mph.
4 Tungsten slugs inside the SpeedBalance weigh 2.5 grams each
allow for custom wheel balancing up to 10 grams to offset valve
stem weight and create perfectly balanced wheels to eliminate high
speed vibrations and improve handling.
SpeedBalance Kit comes with:
- 2x SpeedBalance Pods (each pod contains 1 magnet and 4 Tungsten
- 2x SpeedShield Aero Valve Stem Pod
Upgrading 2 Wheels with SpeedBalance and SpeedShield will save
just over 1 Watt at 30mph, slightly more savings than upgrading
that same wheelset to Ceramic Bearings.
Who Needs It?
Performance oriented cyclists with carbon wheels can all benefit
from SpeedBalance. Balanced wheels improve handling, comfort and
confidence, particularly on high speed descents, while the
aerodynamic benefits of the SpeedBalance magnet over spoke mounted
magnets results in a wattage savings equivalent to a full wheel
ceramic bearing upgrade at a tiny fraction of the cost.
