If you bring the bike over to me (I'd come to you but no wheels at mo) I'll have a look at it

It might be something I can sort for you very quickly

If not I can more than likely tell you what it needs to sort it out

If it's not working as it should it isn't fine

Struggling along with a bike that's not as it should be is very laudable

But if there is a quick "fix" then I think you should at least try the option

Let me know if you'd like some help
