Bike seat (Thorpe St Andrew NR7)

This is / was an excellent bike seat, great quality but the back screw fell off and we’ve not been able to replace it. ( doesn’t seem that Thule provide a replacement screw cap) So this would only be suitable for someone who is happy to tighten it and leave it on the bike. It’s safe to use, but not easy to take on and off: we have a key to secure it.
