Product Details

Overview & Technology

Precision forged construction: The Omega stem is 3D forged from AL6061/T6 and finished with CNC machining to optimise wall thickness and remove excess weight while preserving stiffness where it matters. The result is a lightweight stem that resists flex under sprinting and hard cornering. Durable clamp hardware: A cold‑forged 4‑bolt alloy faceplate secures 31.8mm handlebars with even clamping pressure, while chromium‑moly (Cr‑Mo) bolts provide corrosion resistance and proven strength. With a 40mm stack height and a ±6° angle, the Omega balances low profile fitment with small ergonomic adjustments.

Key Features & Benefits

Lightweight, race‑ready performance: Weighing just 122 g for the 70mm length (139 g for the 100mm), the Omega delivers a clear weight saving without sacrificing rigidity—ideal for riders trimming grams or building fast gravel and road bikes. • AL6061/T6 3D forged + CNC: Optimised strength‑to‑weight and consistent quality across sizes. • 4‑bolt cold forged faceplate: Even load distribution reduces point pressure on bars and avoids deformation. • Cr‑Mo bolts: Tough, corrosion‑resistant hardware engineered for reliable clamping torque. • ±6° angle & 40mm stack: Small position changes for personalised fit without adding bulk.

Fit, Compatibility & Installation

The Omega is built for a 31.8mm handlebar clamp and a 1‑1/8" (28.6mm) steerer tube—standard sizes on modern road and gravel bikes. Available lengths: 60, 70, 80, 90 and 100mm to fine‑tune reach and steering geometry. Installation notes: Use a calibrated torque wrench and tighten faceplate bolts evenly in a cross pattern. Typical recommended torques: faceplate bolts ~5–6 Nm and steerer clamp bolts ~6–8 Nm, but always follow the handlebar manufacturer's torque specs if using carbon bars. Apply carbon assembly paste for carbon handlebars and recheck bolts after initial rides.

Who It's For

The FSA Omega is aimed at road and gravel cyclists who want a lightweight, stiff stem with clean aesthetics and reliable hardware—bikepackers who prioritise durable parts and racers trimming grams will both appreciate it. It's a versatile, value‑packed option for upgrades and builds. If you run carbon bars, the Omega works when paired with proper interface prep and conservative torque settings; alloy‑bar riders get the full clamping advantage straight away.

Frequently Asked Questions

What torque should I use on the faceplate and steerer bolts?

Typical torque values are ~5–6 Nm for the faceplate bolts and ~6–8 Nm for the steerer clamp bolts. Always tighten bolts gradually in a cross pattern with a calibrated torque wrench and follow the handlebar manufacturer's torque recommendations—especially for carbon bars.

Is the Omega stem safe with carbon handlebars?

Yes, the Omega can be used with carbon handlebars if you follow carbon‑specific assembly practices: use carbon assembly paste, reduce clamp torque to the bar manufacturer's maximum, and inspect the bar face for damage. If unsure, consult the bar maker or choose a stem specifically certified for carbon.

Which length should I choose—60mm, 70mm or longer?

Choose stem length based on rider fit and handling preference: shorter stems (60–70mm) quicken steering and suit tight handling or compact frames; mid lengths (80–90mm) give a balanced reach; 100mm and above lengthen reach for more stretched positions. When in doubt, make small incremental changes (10mm) from your current setup.

How much does the stem weigh?

Weight varies by length: the 70mm Omega weighs approximately 122 g and the 100mm option is about 139 g. Exact weight depends on the length chosen and manufacturing tolerances.

Can I use this stem on a tapered steerer or an oversized fork?

The Omega is designed for a straight 1‑1/8" (28.6mm) steerer. It will not clamp an oversized or tapered (1.5" lower) steerer without an appropriate shim or adapter—ensure compatibility before installation.

How often should I check the bolts after installation?

Re‑check bolt torque after the first 50–100 km (30–60 miles) of riding and periodically thereafter, especially after heavy rides or if you ride in wet conditions. Regular inspections catch loosening, corrosion, or clamp mark issues early.

Buying Guide

When choosing a stem, match clamp diameter (31.8mm) and steerer size (1‑1/8") first—these are non‑negotiable. Then pick length and angle to tune reach and handling: shorter lengths make steering quicker; longer lengths stabilise high‑speed tracking. The Omega offers a lightweight, stiff alloy option that suits riders who want performance without the premium price of forged carbon. Consider your bike's intended use: racers and weight‑sensitive riders will prioritise the Omega's low mass and stiffness, while endurance and mixed‑terrain riders may prefer a slightly taller stack or angled stem for comfort. Always factor in handlebar shape and brake/shift lever position when finalising stem choice.
