What to Compare Before Buying
- Chain size: This chain is 1/2" x 1/8". Compare that with your drivetrain’s required size.
- Speed type: This is a single speed chain. Check that your bike uses a single speed setup.
- Link count: The chain has 100 links. Confirm that the length works for your setup or sizing method.
- Bike type: The chain is aimed at BMX freestyle and track bikes. Make sure those are the right application for your build.
- Included configuration: Confirm the selected offer matches the chain configuration you want, including quantity and length.
Choosing the Correct Version
For this chain, the main version checks are the 1/2" x 1/8" size and the 100-link count. Those two details matter most when comparing offers.
If your drivetrain needs a different chain size or a different link count, choose a different version before ordering.
Before You Decide
Confirm the 1/2" x 1/8" size, the 100-link length, and the single speed setup before choosing an offer. If your bike does not use a single speed BMX or track chain, this is not the right match.
