Hi, I have a halo combat.. and very time i ride it the wheel gets stiffer and stiffer till eventually it hardly spins at all, making riding very difficult.. 

Could it just need greasing up a bit or could it be something more serious like the bearings being kaput?
I'm not to good with hubs and stuff so i haven't taken it apart yet, but slightly undoing the hub is how i make it run fine again.. for a while!

Thanks,
Hoernig. 

Its the stock hub on a combat.. im not sure what it is, but it has no writing on it, if that helps?

Awesome, ill give it a go tonight!

 

My had this happen on his shimano hub, and it actually crushed the race inside the hub. They were 4yrs old though it's probably not the same.. just thought it might be helpful, also do the work asap! or it might cost you a bombload
