ACS Crossfire Bicycle Freewheel Reviews

Customer Ratings:

Only the models with 16T or more are standard ISO thread, which is what flip-flop hubs have. 15T and less are for M30 thread, which is only on weird BMX bikes.

I have a formula flip flop hub and I am in the middle of having a terrible time removing this freewheel. The removal tool does not fit over the inner axle nut and removing the inner axel nut is proving to be a close to impossible task since you need to leverage against a second inner axel nut, but you cannot get your wench over the second inner axle nut because the freewheel covers it.

I used this on a Flying Pigeon PA-02, replacing the stock 18T freewheel and dropping the gear-inches to make hitting the hills easier.

It went on perfectly, and runs without a hitch. The three locking pawls make for fast engagement, no more than maybe 5-8 degrees at the crank.

The ratcheting action of the three pawls is incredibly smooth. Unloaded my wheel will spin upwards of a minute with a single pedal stroke. Click-a-click-click.

No problems otherwise after 300-500 miles in a cold-dusty environment, and one full immersion in water. (whoops)
