Very nice parts good value for money great colour

### ⭐ Too wide for purpose.
*by M***S on 26 March 2025*

The tensioners are too wide and stop the wheel being tightened within the dropouts, making these useless. Look nice but not suitable for the job on my bike.

### ⭐⭐⭐⭐⭐ I had these quite a while
*by J***R on 5 April 2025*

I haven't touched these yet but I know it will do its job but now the bike I was going to put them on I do not have so it's probably the later project
