Speedline Parts | Tapered Full Carbon Fiber 20mm BMX Pro Fork
$ 399.95 - $ 429.95$ 0.00 - $ 145.00
The Speedline Tapered Carbon Fiber BMX Pro is the pinnacle of our carbon fork line. Produced from specialized Toray High Modulus, Nanocarbon Composite Material, it's our lightest and strongest fork yet!
The nanocarbon allows our engineers to build stronger, lighter, stiffer carbon parts with a higher impact resistance than ever before. It's 27% stronger than other carbon materials. It's also more flexible with a higher fatigue resistance. Through the high-impact compaction process, we produce more consistent products with denser material minimizing void areas.
The tapered 1 1/8" - 1.5" monocoque carbon fiber steer tube further enhances strength and weight reduction. The advanced engineering, paired with proprietary materials, produces a 20mm Carbon race fork weighing just 16 ounces!
Offset: 28mm
Axle to Crown: 362mm
All Speedline 20mm Pro Forks include Pro Adapters allowing the use of any 3/8" Female axle front hub, meaning you don't need a 20mm front hub to use these forks.
Forks also include a compression top cap for proper installation.
All Speedline Tapered Steertube Carbon Fiber Forks feature 20mm dropouts.
Available in Gloss Carbon, Matte Carbon, and White.
We recommend the use of the Speedline Tapered Sealed Bearing Headset with this fork for optimal seating and fitment.
This tapered fork can only be used on frames that feature a tapered head tube. For more information on this, refer to our tapered head tube blog right here.

These pair great with my Envy RS7. As a duo, these forks allowed my bike to have a very comfortable feeling geometry. My bike feels planted through the corners and straights while remaining nimble and maneuverable. 10/10 my favorite fork I’ve ridden!!!

The fork is lighter than any I have seen before. I haven’t had a chance to test it out yet, but I have always been happy with other Supercross products.

Let’s face it. When this sport goes beyond having fun and you have real talent to develop, these are the parts to get it done. If you want quality and results, buy Supercross and Speedline. Even if you’re a factory dad and building top shelf bikes for kids under the age of 9. Spend the money, it’s worth it.

Since my son was a child, today he is 17 year old- we love the supercross products.

Loved it all! My son was stoked when the polished mirror frame arrived! Just needed to supplement missing parts/out of stock parts, so it's taking a while to build a complete bike.
