  • The Noster S is the fourth version of Simone Barrco’s frame from Subrosa, so they felt that a change in spec was needed.

    With Simone’s riding always evolving, he’s constantly trying to improve the way his bike performs so when he mentioned his ideas, Subrosa were happy to accommodate them.

    The rear end has been shortened, the Noster III was sitting at 13.75″ but that's been shortened up to sit centered in the rear dropouts at 13.55″, or 13.35″ with the axle fully slammed in the dropouts. A nice length for the rear end that will make the frame more responsive, but not feeling too short and twitchy.

    The Noster III was a completely brakeless model, meaning, no brake mounts at all. While most riders are brakeless at the moment, there are a ton of riders that love using brakes. No mounts creates a smooth clean look, but there’s no way to mount U-Brakes to the frame, so for the Noster S the mounts were added back on. The Noster S also has a new seat stay bridge.

    There is a smooth, curved 5mm thick plate that adds to the side to side strength of the frame and also improves braking performance. While the rear end of the frame is shorter, it has been kept wide, so even with your wheel fully slammed you will still have clearance for any size tyre.

NEED SOME HELP UNDERSTANDING FRAME GEOMETRY?

bmx frame geometry can look daunting but thanks to our handy guide below you will have it figured out in no time, and remember we're all bmxers here, so if you have any questions just ask.

Frame Size Chart


Frame Sizing is very much a personal preference, some riders like them longer, others shorter - here's a rough guide - if you have any questions remember we are here to help! 

3ft - 4ft - best suited to a 16" or 18" wheeled bike
4ft - 5ft - 18" to 20" top tube
5ft - 5ft 4" -
20" to 20.25" top tube
5ft 4" - 5ft 8" -
20.25" to 21" top tube
5ft 8" - 6ft -
21" to 21.25" top tube
6ft Plus -
21" top tube or longer

Frame Geometry

Frame Geometry can take a bit of understanding - but here at SourceBMX we are here to help! The first thing to understand is that BMX frame Sizing is best measured by the length of the Top Tube - shown here as TT. Keep reading on to understand how the angles change how your frame will feel and check out our sizing chart below! 

Headtube Angle (HT)

Head tube angle determines the angle of your forks. A steeper HT (i.e 75°and higher) will make the bike turn quicker than a mellower angle (i.e 74.5 and lower°). The more responsive the frame, the more twitchy it will feel, especially at highspeed!

Chain Stay Length (CS)

The chain stay is essentially the length of the rear end of the bike. A shorter CS length will make the bike more responsive and a longer one more stable. As a rough guide a 13.5" long chain stay is about average.

Seat Tube Angle (ST)

Seat tube angles don’t vary too much (around 71°) and affect the centre of gravity. The steeper the angle the shorter your bike will feel. Some frames have a mellower seat tube angle (example 69˚) which makes for a longer frame without actually being longer and reduces how fast your frame turns.

Stand Over Height (SO)

Standover height is essentially how high your frame is. A frame with a low standover height is more responsive and easier to ‘throw around’ whilst a high SO height is more stable; particularly useful when going fast.
