MAGENE – PES P515 Güç Ölçer Krankset – 167,5mm

The Magene PES P515 Power Meter Crankset in 167.5mm is a specialized length designed to optimize pedaling efficiency, particularly for riders looking to reduce hip angle closure at the top of the pedal stroke or those with specific bike fit requirements.

As of early 2026, this model is a top-tier budget alternative to Shimano Ultegra/Dura-Ace power meters, offering dual-sided data through its spider-based design.

## Key Specifications (167.5mm Model)

### Why Choose the 167.5mm Length?

• Biomechanical Advantage: Moving from a standard 170mm or 172.5mm to a 167.5mm can help open up the hip angle, potentially increasing power output in an aggressive aero tuck and reducing the risk of knee or lower back strain.

• Cornering Clearance: A slightly shorter crank provides marginally better ground clearance when pedaling through tight corners in criteriums.

### Compatibility & Installation

• “Drop-in” for Shimano: If your bike currently uses a Shimano crank (24mm spindle), you can swap this in without changing your bottom bracket.

• Chainring Versatility: It is compatible with standard Shimano 110 BCD 4-bolt chainrings (like R7000, R8000, R8100, R9100, R9200). Note that it is not compatible with GRX-specific chainrings due to different offsets.

• Auto-Calibration: Supports back-pedal calibration and active temperature compensation, so your data stays consistent even as the morning warms up.

### Turkey (Türkiye) Market Note

In Turkey, these are frequently distributed by retailers like House of Bike. The “Ultra Dark” or “PES” series components are popular because they provide high-end performance (ceramic bearings in the wheels, ±1% power accuracy here) at roughly half the cost of major European/Japanese brands.

Pro Tip: When installing, ensure you use a torque wrench to tighten the spider lockring and crank bolts to the specified 12–14 Nm to maintain power accuracy.
