Dartmoor Thunder BCD 35 mm Stem

Are you looking for an uncompromising stem that can handle the rough abuse on trails while giving you total control over your bike? The Dartmoor Thunder is an extremely strong, compact, and stiff stem designed specifically for modern, aggressive riding disciplines such as Enduro, Downhill, Freeride, and demanding e-MTB. Thanks to its short length and zero rise, it immediately sharpens your handlebar response to every body movement. Equip your bike with a component you can 100% rely on in even the most brutal terrain.

Key Features of the Dartmoor Thunder Stem

• Premium 7075 T6 Alloy: Made from high-grade aircraft aluminum for maximum strength while maintaining low weight.
• Machined from a Single Block: Precision full CNC-machined construction eliminates any weak spots.
• 35 mm Clamp Diameter: A modern standard ensuring high cockpit stiffness without unwanted flex.
• Ultra-Short 38 mm Reach: Improves bike handling and offers immediate steering response when changing directions.
• FEA Analysis Tested: The construction underwent computer and real-world testing for impact overload.

7075 T6 Aircraft Aluminum and Full CNC Machining

The foundation of the Dartmoor Thunder stem's massive strength lies in using top-tier 7075 T6 aluminum. Unlike standard cast or forged stems, the Thunder is completely machined from a single block of material. This manufacturing process guarantees a homogeneous metal structure free of internal defects or microscopic cracks. The result is an extremely solid, stiff cockpit that won't yield even during big jumps, harsh cased landings, or hard impacts on rock gardens.

Progressive Geometry and Uncompromising 35 mm Stiffness

Modern trail and enduro bikes require short stems for optimal weight distribution and lightning-fast front-wheel response. With a 35 mm clamp size and a super-short 38 mm reach, you get instant feedback from the trail. Forget about flexing or twisting handlebars when railing berms aggressively—the wider clamping area effectively distributes load and gives you confidence in fast technical sections as well as steep descents.

Perfect Safety and Clean Cockpit Design

The stem features a 4-bolt faceplate that clamps the handlebars firmly and evenly without risking damage or slipping. Smooth lines and rounded edges prevent knee strikes during wild maneuvers. Thanks to clever CNC weight optimization, the Dartmoor Thunder weighs just 155 grams, making it the ideal choice for riders looking for the ultimate balance between light weight and raw strength.

Frequently Asked Questions (FAQ)

Will the Dartmoor Thunder stem fit my handlebars?

This stem is engineered for the modern 35 mm handlebar clamp diameter. Please double-check that your handlebars measure 35 mm at the center clamping area before purchasing. It is not compatible with standard 31.8 mm handlebars without shims.

Is this stem suitable for e-bikes (e-MTB)?

Yes, the full CNC-machined body crafted from 7075 T6 aircraft-grade aluminum alloy provides more than enough strength reserve to handle the extra stress and weight of modern full-suspension e-bikes.
