Why do you use a 44mm headtube?

A 44mm headtube allows you to run either standard 1 1/8” or tapered steertube forks depending on the headset you use.


What kind of headset do I need?

To run a 1 1/8" straight steertube, you need a 44mm Semi-Integrated headset. It is a Zero Stack internal headset where both upper and lower cups are pressed in the headtube.

Here's an example.

To run a 1 1/8" - 1.5" tapered steertube, you need a ZS44/EX44 headset. The upper cup is internal (Zero Stack) and the lower cup is external. 

Here's an example.


What is the difference between MTB spacing and BMX spacing?

The difference is the spacing for the rear hub. The standard for Freestyle MTB is a rear hub axle measuring 135mm wide by 10mm in diameter. That is the most common option, which we refer to as "MTB Spacing".

Some Freestyle MTB riders decide to build a 26" rear wheel on a BMX hub for various reasons ranging from strength, cog size or to have a Left-Hand drive hub. The standard in BMX is a rear hub measuring 110mm wide by 14mm in diameter.

The "BMX Spacing" version has the exact same geometry as the "MTB Spacing" one, but it allows the use of a BMX rear hub (110mm X 14mm) instead of a MTB rear hub (135mm X 14mm).

Note that the MTB version allows the use of a Disc Brake, while BMX version is Brakeless Only.

I received my frame but it's missing the Seatclamp Bolt & Cable Guides.

The seatclamp bolt and cable guides are included in every box. They are located in a plastic bag taped to the short flaps inside the box.
