Description

Colony are back with another dialled street orientated frame. The Colony Prisma BMX frame has the progressive geometry we've come to expect from Colony, with a steeper head angle of 76.3°, a nice and short rear-end of 12.7" slammed and your choice of either a 20.7 or 21 Inch top tube length.

Features
  • Progressive street geometry. A 76.3° head tube angle with a 12.7" slammed rear end makes the Prisma quick to turn and easy to bring around.
  • Full CrMo construction. Gussets on the top tube, down tube and between the chain stays put material where street riding loads the frame hardest.
  • Heat treated at the stress points. The CrMo head tube, mid BB shell and dropouts are heat treated, so the joints that cop the most abuse are the strongest parts.
  • Ovalised down tube and chain stays. The shaping is there to resist denting when the frame comes down on rails and ledges.
  • Removable mounts and tensioners. Chain stay brake mounts, gyro tabs and chain tensioners all come off, and the brake hardware is included if you run them.

Specifications
  • Sizes: 20.7" and 21" top tube
  • Chainstay: 12.7" slammed
  • Head tube angle: 76.3°
  • Seat tube angle: 70.0°

  • Bottom bracket: Mid, heat treated shell
  • Material: Full CrMo
  • Tubing: Ovalised down tube and chain stays, gussets on top tube, down tube and between chain stays

  • Brake mounts: Removable chain stay mounts and gyro tabs, removable brake hardware included
  • Head tube: 125mm, heat treated
  • Weight: 2485 grams (20.7")

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.
