SILCA has announced a new product called, SpeedBalance, which is designed to correct imbalances found in carbon fiber wheels by using a simple counterweight application.
“As carbon wheels become deeper and valve stems become longer and heavier, light carbon wheels become susceptible to imbalance – roughly 10-20 grams,” says SILCA. “At high speeds this is a big deal, and the SpeedBalance solves this issue.”
Most imbalances occur as a result of the long valve extenders associated with deep section wheels, along with the internal reinforcing weight that’s found in the rim.
The aim of SpeedBalance is to offset this imbalance by placing counterweight(s) in discrete locations along the rim of the wheel.
SpeedBalance uses 2.5g tungsten weights with adhesive backs, which can be placed in problems area, particularly in and around area of the valve stem.
“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,” adds SILCA.
The SpeedBalance is available for $36 directly from SILCA.

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:
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.
