Cassette spining

[2good]

Hi

The cassette on my road bike has started spinning both ways. I believe it's the freehub?

I took of the cassette and cleaned the hub and squirted some lube into the hub.

All fine, went for a ride and its doing the same again?

Do i need to replace it?

Thanks

Yes.

Depends on the hub.

A bit of a generalisation but:

None of the below - whole new hub usually.

Shimano - new freehub

Mavic, Fulcrum or Campagnolo - may be serviceable.

What make is the wheel?

What wheel set is on the bike? If it is low end stuff (like it was on mine and I have Sora too) then you are probably better replacing the wheels. If they are great wheels with rims that have lots of wear left then you might want to try and sort the freehub out.

You can get Shimano R500 budget wheels for around £70-85 depending where you shop.

If its still spinning both ways and is a shimano one then its very likely to be broken. Removing it is simple, just take the rear axle and bearings out, then get a big allen key and undo it. It may be quite stiff but its straight forward enough. You cant really service the freehub except for cleaning/lube.

Buying a new one is an option, have a quick look online to see how much you can get one for and then compare this to the cost of a new wheel. You need to take into account bearing/cup/condition, value of current wheel and current rim wear...

All in, its pretty straightforward. Just balance the cost of fixing to the cost of replacing!
