About this item
- This bike stem riser is designed to fit standard 1-1/8" (28.6mm) fork stems, seamlessly compatible with MTB, mountain bikes, road bikes, and BMX. No more worrying about mismatches—whether you’re commuting, off-roading, or casual riding, it’s the reliable riser that saves you from repeated returns.
- Choose from 6 precise lengths (90mm/115mm/135mm/150mm/180mm/210mm) to adjust your handlebar height freely: 90mm for mild lift, 115-135mm for daily commutes (eases neck strain), 150-180mm for off-road MTB control, 210mm for max extension. Each size is clearly marked, so you pick the perfect fit without guesswork.Choose from 6 precise lengths (90mm/115mm/135mm/150mm/180mm/210mm) to adjust your handlebar height freely: 90mm for mild lift, 115-135mm for daily commutes (eases neck strain), 150-180mm for off-road MTB control, 210mm for max extension.

- Crafted from forged 6061-T6 aluminum alloy, this bike stem riser handlebar extender is corrosion-resistant (handles rain, mud, and outdoor wear) and lightweight (113g-287g, no extra bike burden). It withstands daily bumps and off-road impacts, while the smooth finish prevents handlebar tape damage.
- We include 2 hex keys and a step-by-step guide—install this bike stem handlebar extender in 6 simple steps, even if you’re new to bike DIY. No professional tools needed: just remove the original handlebar cover, attach the extender, adjust height, and secure screws. Done quickly!
- This bike handlebar extender lifts your handlebar to an upright position, reducing hunching and neck/back strain during long rides. For MTB riders, it improves steering response on rocky trails; for commuters, it makes city navigation more comfortable. It’s not just an extender—it’s a ride upgrade.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
