### ⭐⭐⭐⭐⭐ Decent
*by R***Y on 9 September 2024*

I like it, riding to work with this daily on my 2014 Norco Heart single speed bike and have had no issues so far. The hardest part of the process was getting my old freewheel off, I ended up having to take quite destructive measures. After that, the new one just threads on and you pedal away. Looks like this one can be removed with a traditional freewheel tool too if necessary. It's relatively quiet but has a satisfying tick and engages well. Very happy.
