DMR Defy50 Vapour Blast MTB Stem

DMR Defy50 Vapour Blast MTB Stem

The DMR Defy50 Vapour Blast MTB Stem combines a 50mm reach with a low-profile design for trail, dirt jump and all-mountain riding. CNC-machined from 6061 aluminium, it features a wide bar-clamping area, internal steerer clamp and rounded rear profile for a clean finish.

The Defy50's internal clamping design keeps the rear of the stem smooth and uncluttered, moving the clamping hardware out of the way. The body is also machined to reduce weight while retaining the wide bar-clamping area, internal steerer clamp and strength of the design.

With an 8.1mm rise and 31mm stack height, the Defy50 provides a practical combination of reach and handlebar position for a range of MTB setups.

The Defy50 is available with either a 31.8mm or 35mm handlebar clamp. Its Vapour Blast finish gives the stem an ultra-smooth matt appearance, with Bronze, Silver and Black options available.
