We have a large range of Supercross cromo forks that just might be what you are looking for.
The newest forks out of Supercross, the Pro SLT are just 835 grams with a built in headlock(for the 20″ fork) and have NO rider weight limit, have been selling like hot cakes. Unbeatable strength, weight and an awesome price tag to match. How do they compare with carbon forks? You do the math. If you are racing, hitting up the dirt jumps or skate park these are the fork for you.
If you want to go lighter you could look at the Pro LT forks which are 775 grams with a built in headlock (for the 20″ fork) with a rider weight limit of 170lbs.
If you want to save a few bucks check out the more traditional looking Pro fork, they are just 950 grams with a built in headlock (for the 20″ fork) and have been in the Supercross product line up for 20 years.
There’s also a heat treated cromo Mini/Jr fork with a 1″ steer tube for the little Radsters which are a scant 540 grams (no built in headlock).
