Specifications

What are the spindle dimensions?

Wert cranksets feature a 29mm diameter spindle and support the following outer bearing width (OBW):

• Road: 93.5mm for 68mm BB shell & DUB BB with 3mm spacer
• Gravel: 98.5mm
• MTB: 113.5mm

These dimensions are optimized for modern bottom bracket standards and proper chainline configurations.

What crank arm lengths are available?

Wert crank arms are available in: 157.5mm, 165mm, 170mm, 172.5mm, and 175mm to accommodate different rider sizes, riding styles, and terrain preferences.

What Q-factor do our cranks have?

Q-factor is the outside-to-outside distance measured between the pedal surfaces of the two arms.

• Road: 144mm
• Gravel: 149mm
• MTB: 159mm

Note: While most MTB frames provide clearance for Wert StW MTB cranks, some frames may give interference issues that added spacer with may solve, providing there is enough driveside spline overlap. Wert can supply a custom length axle for a surcharge.

What chainring interface does Wert use?

Wert cranks utilize a 8-bolt compatible direct mount interface. This interface accommodates various single chainrings and is compatible with aftermarket spiders (with or without integrated power meters) that support different bolt circle diameters (BCD) for your existing or preferred chainring setup.

What chainlines are supported?

Typical chainline measurements with Wert cranksets:

• Road 1X: 44.7mm with compatible direct mount chainring
• Road 2X: 43.5mm with compatible road spider
• Gravel 1X: 47.5mm with compatible direct mount chainring
• MTB 1X: 55mm with compatible 3mm offset chainring

How much do Wert Cranksets weigh?

Wert cranksets start at 294 grams for arms and spindle (without bottom bracket, chainrings and bolts), making them among the lightest titanium cranksets available.

Installation & Maintenance

What are the recommended torque specifications?

For optimal installation:

1. Apply 0.7 Nm bearing preload torque using an HG cassette tool when installing the drive-side crank arm onto the axle
2. Secure the drive-side crank arm and axle with 25 Nm using an 8mm hex key bolt

We strongly recommend using a calibrated torque wrench for installation.

Do Wert Cranks require special preparation?

Use Ti-Prep anti-seize compound or standard petroleum-based grease on all titanium threads (spindle, bolts, pedal threads) to prevent galling and to ensure smooth operation.

Are pedal washers required?

No, pedal washers are not required with Wert cranks, unless specifically recommended by the pedal manufacturer. We generally prefer installation without washers.

Warranty

What warranty do Wert Cranksets include?

Wert provides a 3-year limited warranty to the original retail purchaser against manufacturing defects. This warranty excludes normal wear, crash damage, and issues resulting from improper installation.
