Frequently Asked Questions

How do I know if I need a 1.00kg spring?

Spring rate depends on your weight, riding style, and bike setup. Race Tech offers over 500 rates — measure your current springs or consult Race Tech's spring rate calculator to confirm the right weight for you.

Will this improve my bike's handling?

Yes — proper spring rates eliminate the wallowing and unpredictability caused by under-sprung forks, giving you more control and predictability in cornering and braking.

What's the advantage of chrome silicon construction?

Chrome silicon wire has a high strength-to-weight ratio and resists fatigue, ensuring consistent spring rates and durability even after years of hard riding.

Will the spring sack out over time?

No — these springs are shot-peened and heat-treated to resist sacking-out, maintaining accurate rates throughout the life of the fork.
