Overview
Our bike with transition and trail riders in mind. We took Sergio Layos and Josh Dove as inspiration to build a bike that even they could ride straight out of the box. The Orion comes equipped with the full range of Ruben Alcantara signature parts, including the new Ruben 2 Grips. For 2021, the Orion comes in a new Flat Metallic Green colorway, along with a Flat Black option with polished hubs, seat post, and stem that will catch your eye.

Frame Geometry
A: Top Tube Length: 21″ – Learn what size is right for you here.
This is a tall toptube.
Perfect for riders that are between 5’7″ to 6’4″
Getting a top tube that is taller than suggested will make the bike feel more controlled and less responsive
Getting a top tube size that is smaller than normal will make the bike feel a lot more snappy and responsive.
B: Chain Stay Length: 13.7″ – Learn About Chain Stays Here
This is a long chain stay.
This will make the bike feel stable and controlled.
A short chain stay makes the bike feel twitchy. Spins will be easy, but airing and jumping might feel hard to control.
A long chain stay will make the bike feel really controlled. Spins will feel sluggish, but manuals and air tricks will feel nice because it will be more stable and controlled.
C: Head Tube Angle: 74.5° – Learn About Head Tube Angles Here
Steep head tube angles make the bike “snappy” meaning more responsive to fast turns.
A less steep head tube gives you more control.
D: Seat Tube Angle: 71°
E: Bottom Bracket Height: 11.5″
F: Stand over height: 9.25″
This is a tall standover.
A tall standover gives the bike a responsive and snappy feeling. Good for barspins and controlled riding.

G: Rise: 9″
Riding a tall rise, will give you more leverage on the bike. Making it easier to pull back and lift the front wheel up.
H: Width: 29″
This is a medium width.
Narrow bars make barspins easier.
Wide bars give you more control and stability when steering.
I: Backsweep: 10º
What does backsweep do?
As far as I know, there is a sweet spot for backsweep. Too much will make the bike feel weird, and too little will make the bike unstable. It seems like the sweet spot is around 11º to 12º. If you need something a little more aggressive and straight feeling, go for 10º, but only do this if 11º is uncomfortable.
J: Upsweep: 2º
This is a normal upsweep!
What does upsweep do?
There is a lot of discussion about 1º upsweep vs. 4º upsweep. Some people are running experiments and testing if the greater upsweep will make drops feel better. It seems like a lot of street riders run 4º to 5º upsweep. This helps for wrist pain and lessens the impact of big drops.
