Don't understand what you are asking me on the spring weightthanks todd...Do you think there is truth to the different spring weight?in a few weeks todd i will be contacting you for a sheave but wanted a little more aggressive spring.....like always todd thanks for the info your the man
We use the gold up to 28 tires and the purple is actually weaker and not worth using. We use a purple/black for 29" and tallerGold spring is good for up to 30" tires. You get to much spring and you'll just be bouncing off the rev limiter waiting for it to shift up. The next step up is the Purple spring.
