Compatibility, Size and Fit
Confirm that the frame accepts a bolt-on rear hub and check the required axle spacing. Also verify that the rim, spokes and 1-speed freewheel are compatible with the hub. The listing title includes “28 x 110” but does not explain what “110” measures, so do not rely on it as a fit specification until its meaning is confirmed.
What to Compare Before Buying
- Check the frame’s axle interface and required spacing against the hub.
- Match the hub’s 28-hole drilling to the rim and confirm the spoke fit.
- Verify compatibility with the intended 1-speed freewheel.
Before You Decide
Confirm fit with the frame, rim and freewheel, and clarify the “110” notation if that measurement matters to your build.
