Frame Geometry

A: Top Tube Length: 21″ – Learn what size is right for you here.

Check the size guide to see if its right for you..

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: 13.2" – Learn About Chain Stays Here

This is a medium chainstay.

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.

C: Head Tube Angle: 75° – 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: 11.75″

F: Stand over height: 9.5"

This is a tall standover.

A tall standover makes your seat higher up and will allow you to pinch it easier when learning barspins.

G: Rise: 9.5"

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: N/A

This is a wide width.

Narrow bars make barspins easier.

Wide bars give you more control and stability when steering.

I: Backsweep: N/A

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: N/A

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.


There are two different 2021 Stolen Sinner FC options. The Sinner FC is $609, while the Sinner FC XLT is $709. The reason for this difference is because the XLT is the super high-quality version. Which includes more high-quality stolen aftermarket parts. This does make it worth the $709 price tag.


Along with FULL chromoly 4pc bars, forks, and frame, the 2021 Stolen Sinner XLT comes with strong 48 spline cranks, stolen sumo sprocket (with guard), and stolen hive tires to name a few. Overall, this bike has everything that you'd expect from a high-level BMX bike.

There is a reason that this is one of their most popular bikes.The amazing quality will keep this bike rolling for al ong long time. The frame geometry is mostly for a taller rider so make sure you double check that before buying.

If you are brand new you can still get this bike, but be sure that you plan to ride for a while, otherwise you will be wasting your money. Especially if you quit right away.

A mid-level rider will enjoy the specs and the quality, but so will a high-level rider. The Sinner XLT can take anything you throw at it. $709 is a lot, but it is totally worth the price.
