## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy to fit and secure wire clamp
*by S***Y on 17 August 2024*

I got this as my sons derailleur had been bent and wasn’t running as smoothly as normal. This was mega easy to fit. The tube clamp fit well and is very secure and the wire clamp is simple and hasn’t slipped.Since fitting we have essentially forgotten all about it: demonstrating that it does everything we wanted! Great value!

### ⭐⭐⭐⭐⭐ Good value
*by J***R on 1 August 2024*

I picked up a bike from one of the freebie sites a while ago and I’m in the middle of making it roadworthy again. The front derailleur mechanism was rusted solid so I removed it and this product is an affordable replacementThe build quality seems good – Maybe not suitable for a professional cyclist but certainly good enough to let me potter around the local streets
