Bicycle stem designed to sharpen steering and reduce unnecessary weight for riders upgrading their cockpit. PLATT Bike Stem helps riders feel more confident and connected on technical trails and busy roads. Is it the right upgrade to improve handling and fit on your bike?
⚡ At a Glance
- • Handling Precision: Stable steering response thanks to a stiff aluminium construction and a secure four-bolt bar clamp
- • Best for: Cyclists upgrading road, mountain, BMX, downhill or track bikes who want firmer control and tailored reach
- • Not ideal for: Bikes with non-standard handlebar or steerer sizes outside 31.8mm bar clamp and 28.6mm steerer
CNC-machined 6061 T6 aluminium gives a durable yet lightweight structure. Available in multiple lengths with a four-bolt clamp and a 31.8mm handlebar interface, plus a 28.6mm (1-1/8") steerer clamp.
Lower weight, with CNC-machined 6061 T6 aluminium
Machining from 6061 T6 aluminium removes excess material while preserving structural thickness where strength is needed. The alloy grade balances tensile strength and fatigue resistance suitable for cycling loads.
Reduced mass helps decrease steering inertia and rider fatigue on long rides, while maintaining the stiffness required for precise control.
Fine-tuned fit, with multiple length and rise options
Seven length options are available, covering 60, 70, 80, 90, 100, 110 and 120mm, and the stem offers a rise of plus or minus 17 degrees. These choices change handlebar reach and height in predictable increments.
Riders can adjust reach and bar height to match riding style and body geometry, improving comfort and handling without changing other cockpit parts.
Secure clamping, with a four-bolt bar clamp and standard interfaces
A four-bolt bar clamp secures the handlebar across a broad contact area, while the clamp diameter is 31.8mm and the steerer clamp is 28.6mm (1-1/8").
Strong clamping reduces the chance of slippage under hard effort and makes installation straightforward for compatible handlebars and forks.
