Find Your Perfect Fit: Custom Crank Setup Made Easy

1. Choose Your Spindle Length

Your frame dictates the spindle you need. We offer three options to match most MTB frames:

2. Nail the Chainline

Want buttery-smooth shifting and max efficiency? You need the right chainring offset:

Model of cranks	standard	wide	superboost
Q-factor, mm	168	174	177
Chainrings 8-bolts	Chainline, mm	Chainline, mm	Chainline, mm
Boost, offset 3mm	52	55	56.5
Super Boost, offset 0mm	55.0

Match this to your rear hub spacing (O.L.D.) to ensure the chain runs straight and smooth.

3. Check Compatibility

Stellar works with most modern MTB drivetrains and accessories, including popular power meter spiders. Just make sure all parts match up — and you’re golden.

Installation Tips

We know you like to DIY — just keep these tips in mind:

• Crank bolts: 8 mm hex, 55 Nm (left-threaded on non-drive side!)

• Preload ring bolt: 2.5 mm hex, 2 Nm

• Pedal torque: 35–40 Nm

Use a torque wrench — your cranks will thank you.

Style Points: Pick Your Color

Why settle for boring black when you can ride with color? Stellar cranks come anodized in 8 stunning shades:

Black | Silver | Red | Purple | Blue | Green | Orange | Gold

Because performance can look good.

Why Shorter Crank Arms Are the New Normal

Longer cranks are out. Modern MTB geometry and riding styles favor shorter crank arms — for better clearance, more control, and fewer pedal strikes.

Stellar cranks are available down to 145 mm — so you can keep your flow even on tight, technical terrain.
