Description

The Joris Coulomb signature Om has been a staple in the Subrosa lineup for years, and this is its biggest upgrade to date. It sticks with the modern geometry Joris and other riders already love, and it is still one of the shortest frames in the collection.

To run a chainstay that short, Subrosa added an investment cast yoke at the bottom bracket junction. It creates a larger welding surface around the shell for more strength against bending, and it leaves room for the widest tyres available. A built in seatpost clamp, new decals and new colourway options finish off the Om V2.

Features
  • Investment cast yoke junction. A larger welding surface around the bottom bracket adds strength against bending and clears the widest tyres available.
  • Short 12.9" back end. Chainstays run from 12.9" to 13.7", making this one of the shortest frames Subrosa builds.
  • Double butted chromoly tubing. 4130 chromoly with a double butted top tube and down tube, at 2.3 kg for the 20.5".
  • Three top tube sizes. 20.5", 20.75" and 21", so you can match the frame to your height and how you ride.
  • Built in seatpost clamp. One less part to buy, alongside a 75° head tube and an 11.7" mid bottom bracket.

20 inch BMX frame sizing

Frames are sized by top tube length. Start with your height, then let riding style decide where in the range you land.

Rider heightTop tube
147 to 157cm19.75 to 20.25"
157 to 168cm20 to 20.5"
168 to 175cm20.25 to 20.75"
175 to 183cm20.5 to 21"
183 to 190cm and up20.75 to 21.5"

The height bands overlap on purpose. If you land in two of them, riding style breaks the tie: longer for flow, trails and transitions, shorter for technical street and park. Plenty of riders, pros included, deliberately ride longer than a chart suggests.

How to measure

Top tube is measured from the centre of the seat tube to the centre of the head tube, so it is not the length of the tube you can see. Measure your current frame that way and compare.

  • Size up for stability through trails and transitions.
  • Size down if you want the bike quick and twitchy for spins and grinds.
  • Top tube is fixed once you buy, but chainstay length, stem length, fork offset and bar position all change how the built bike feels.
