Ensure you measure your frame’s hose routing to confirm the 800mm front and 1450mm rear hose lengths are suitable, as adapters are not included.

This WAKE stem is a superb upgrade for anyone looking to improve their bike’s handling and achieve a more aggressive riding position. The short 45mm length significantly quickens steering response, making technical descents and tight trails much more manageable. Crafted from high-strength CNC machined 6061 T6 aluminum, it feels incredibly solid and inspires confidence, while its low weight of 130g won’t hinder performance.

Installation is a breeze, requiring just a few bolts to secure it to your existing fork and handlebars. While the 31.8mm clamp diameter is standard, ensure your handlebars match this size. If you’re seeking a responsive and robust front-end upgrade for your mountain bike, this stem is an excellent, budget-friendly choice.

They are designed to minimize noise while delivering confidence-inspiring performance on trails and city streets alike.

Compatibility is key, so double-check your caliper model before ordering, as they fit select Shimano, TEKTRO, and TRP systems. While they offer excellent value, extremely aggressive riders might eventually seek out more specialized compounds. For most mountain bikers needing a dependable and affordable brake pad replacement, these are an outstanding choice.
