Adjusting Chain Tension and Alignment on a StarTrac NXT

In this video, we show how to tension and align the chain and flywheel on a StarTrac NXT bike

• First, you see an example of a chain that is way too loose
• To correct this loosen the flywheel bolt on both sides of the flywheel
• Loosen the tension nut on the sprocket side of the bike and tighten the tension bolt until you get the proper deflection on the chain
  • A properly tensioned chain will have roughly 3/16" of deflection
• Tighten the tension nut and the flywheel nut on both sides as shown in the video

Check the Alignment of the Chain and Sprockets after Making a Chain Tension Adjustment

• Misaligned chains will look like they are walking from side to side where they enter and leave the sprockets
  • This can cause noise, premature wear, as well as making the chain look to be jumping from side to side during use
• To correct this, loosen the flywheel nut on both sides of the flywheel, then loosen the tension nut and adjust the tension bolt to move the flywheel in the proper direction needed to align the chain with the flywheel sprocket, as seen in the video
  • Note: If you have already achieved proper tension of the chain, adjusting the tension nut on the opposite side from the sprocket will help to keep the same tension on the chain
• Don't forget to check the chain tension after making an alignment adjustment
