Frequently Asked Questions
What is the difference between the 31.8mm and 35mm clamp variants?
The 31.8mm clamp variant has a 20mm rise and fits stems designed for the common 31.8mm standard. The 35mm clamp variant uses a larger clamping diameter and comes with a 25mm rise, matching many modern direct‑mount or oversize stems. Always match the bar clamp diameter to your stem to ensure safe installation.
Can I trim the Descendant Riser to a narrower width?
Yes — the bar is sold uncut, and you can shorten the grips ends to tune width. Cut equal amounts from both sides, protect the bar ends with plugs, and re‑apply lockrings or clamps. Measure carefully before cutting and leave enough length for your grips, shifters and controls.
How much does the bar weigh?
The Descendant Riser ships at approximately 0.95 lb (≈431 grams). That weight reflects the 7050 alloy construction which prioritizes stiffness and impact durability for aggressive trail use.
What clamp torque should I use when installing?
Always follow your stem manufacturer's clamp torque specification. If the stem spec is unavailable, start with a conservative torque around 5–6 Nm and avoid exceeding 6–8 Nm on aluminum bars to prevent crushing. Recheck clamp tightness after the first few rides.
Are these bars compatible with dropper‑post levers and e‑MTB controls?
Yes — the Descendant's 760mm width and standard grip diameter accommodate modern brake levers, shifters, dropper levers and many e‑MTB control units. Ensure you have enough handlebar length for all controls and consider small relayout adjustments if running large remote levers or displays.
Is 7050 aluminum better than 6061 for handlebars?
7050 is a higher‑strength, heat‑treatable alloy that offers improved stiffness and fatigue resistance over 6061 in many applications. For handlebars, that means better long‑term durability and resistance to deformation under heavy braking and impact loads, making it a strong choice for aggressive riding.
Buying Guide
When choosing a riser handlebar, match width, sweep and clamp diameter to your bike and riding style. Wider bars like the 760mm Descendant increase control and stability on technical trails but may be less practical in very tight singletrack; consider trimming to a personal preferred width. Backsweep and upsweep affect wrist comfort and control — 7° backsweep and 5° upsweep offer a balanced, ergonomic position for aggressive riding. Material and construction matter: 7050 aluminum gives a higher strength‑to‑weight ratio and better fatigue resistance than basic alloys, making it a smart choice for riders who push hard and want a durable, precise cockpit. Finally, always confirm stem clamp diameter (31.8mm vs 35mm) and leave enough uncut bar length for grips and controls.
