## Customer Reviews

### ⭐⭐⭐⭐⭐ Does what it's meant to
*by  on Reviewed in the United Kingdom 16 March 2026*

Need bosses? Here's a set.

### ⭐⭐⭐⭐⭐ Neat solution if you don't have seat stay lugs.
*by  on Reviewed in the United Kingdom 6 May 2025*

Cracking piece of kit that neatly solves the problem if your bike does not have mounting lugs for a pannier rack on your seat stays.

### ⭐⭐⭐⭐⭐ Best way to mount your pannier
*by  on Reviewed in the United Kingdom 4 August 2016*

This is definitely the way to go for fitting a pannier to your bike. It fulfils the role of anchor for your pannier but also a very effective clamp for your seat. This design is far more suitable than alternatives on the website, its clamping action coincides with that of most bike downtubes and is therefore more effective. Strongly recommended
