Cassette Noise (I think)

by dunnoh   April 23, 2014  

I have Fulcrum 5's. When I put pressure on one side of the crank i.e. I stop pedaling and stand up, I get a grinding noise from the hub / cassette. I've replaced the spring and regreased the bearings. Any ideas what it is because its driving me mad. Ta

I had that on my Campag Siroccos and I replaced the rear wheel bearings (sorted)

Got them direct from - same bearings as Fulcrum

Your cassette lockring isn't tight enough.
