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
