What to Compare Before Buying
- Crank length: This model uses a 170 mm crank arm length. Compare that with the length you need for your bike build or replacement.
- Chainring setup: The chainwheel has 48/38/28T rings. Check that this triple setup matches your gearing needs.
- Rear-speed match: It is described for rear 8/7-speed use. Make sure that matches the rest of the drivetrain.
- Bottom bracket type: It is square bottom bracket compatible. Confirm that your bike uses that interface.
- Chaincase fit: If your bike uses a chaincase, confirm that this chainwheel works with your setup.
Compatibility, Size and Fit
This chainwheel is described as compatible with square bottom bracket setups and chaincase use. It is also tied to rear 8/7-speed drivetrains and HG chain use. Those are the main fit points to check before choosing an offer.
For a replacement or build, confirm the crank length, bottom bracket style, rear-speed match, and chainring combination against the bicycle you plan to use it on.
Before You Decide
Confirm the 170 mm crank length, 48/38/28T chainring setup, and rear 8/7-speed match before choosing this chainwheel. Also check square bottom bracket compatibility, chaincase fit, and whether you want the included chainguard.
Chainline and Drivetrain Clearance
For a replacement, also check that the chainline and clearance work with the bicycle’s frame and front derailleur. Matching the crank length, chainring sizes, and bottom bracket interface alone does not confirm complete fit.
