  • 6mm CNC machined dropouts
  • Short 12.75" chainstay, 75.5° head tube
  • Straight gauge tubing

Description

The Nemesis is Radio's street focused frame, built to last and take a serious beating. It is fully heat-treated chromoly with straight gauge tubing for extra dent resistance, and super thick 6mm CNC machined dropouts at the back.

Geometry is short and steep: a 12.75" chainstay and a 75.5° head tube angle for a responsive, agile feel, plus a taller 125mm head tube so you need fewer spacers under the stem. Removable brake mounts and cable guides, and it includes a lifetime guarantee.

Features
  • Fully heat-treated chromoly frame. Put through all kinds of hell by the Radio team across street, park and dirt, and backed by a lifetime guarantee.
  • 6mm CNC machined dropouts. Thick and heat-treated where the rear end takes the most punishment from grinds and hard landings.
  • Short 12.75" chainstay, 75.5° head tube. A tight rear end and a steep front end make the Nemesis quick to turn and easy to throw around.
  • Straight gauge tubing. Chosen for dent resistance rather than the last few grams, so the tubes stand up to knocks and impacts.
  • 125mm tall head tube. Puts your bars higher without stacking spacers under the stem, with removable brake mounts, cable guides and rotor tab holes.

  • Top tube: 20.75", 21"
  • Chainstay: 12.75" to 13.25"
  • Head tube angle: 75.5°
  • Seat tube angle: 71°

  • Bottom bracket: 74mm mid size, CNC machined
  • Material: Fully heat-treated chromoly
  • Tubing: Straight gauge, extra thick for dent resistance
  • Dropouts: 6mm thick, CNC machined and heat-treated

Top Tube Length - 20.75

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.
