DMR Defy Vapour Blast Stem

The DMR Defy stem is the considered choice for your trail, dirt jump or all-mountain bike build. The CNC-machined MTB stem features a low stack height, a top-close clamp design, a 35mm or 50mm reach, and a 23.5mm rise. The stem has a wider clamping area that enhances bar stability, and its compact size complements modern mountain bike geometry. For confidence-inspiring riding whatever riding-level you are at, choose a DMR Defy stem every time.

The Defy50 comes with an internal clamping design – this creates a super-clean look and a rounded-out back end – if you’ve ever banged your knees on your stem bolts, you’ll thank us for the unique design here that tucks everything out of the way.

The Defy 50 stem comes in two clamp sizes – select Defy 50 for the option with a 31.8mm handlebar clamp diameter, while the Defy 50+ stem comes with a 35mm bar clamp diameter.

VB stands for Vapour Blast – our exclusive new process which creates an ultra-smooth matte finish, and available in Black, Silver, and Bronze.

Here’s what MBR Mag said about the DMR Defy stem, “The Defy stem is designed to be a perfect match (aesthetically speaking) with DMR’s own handlebars, but has a few features that make it a very attractive package for any cockpit combination. Twin face plate clamps use a Top-Close clamp design where you tighten both top bolts until they touch the stem body before tightening the lower bolts, ensuring simple, safe and effective bar installation.”

Also bear in mind, the Defy50 is not designed to be super-lightweight with tiny little bolts or flimsy construction that many MTB stems have these days – our Defy50 stem is built to last and built tough. Bikes that come with a long front centre, slack head angle, and fast-AF geometry will experience noticeable improvements with the DMR Defy stem.

"Warning: after you install this stem on your bike, you might forget about it entirely. It won't move, it won't make noise, it won't be damaged in a crash. Its shape won't remind you of its presence... it's perfect. The definition of fit and forget – the Defy Stem!" – Olly Wilkins
