Hi all
Wondering if I could get some help. I replaced my Shimano 8 speed cassette (11-28) with another HG-50 8-speed but with a different teeth combination (13-26). After fitting it I could hear and feel a rumbling noise around the rear derailleur area. I went for a ride round the block and the noise and how the trembling felt through the frame was even worse. I thought it had to do with cable tension but this was ok, I tweaked a bit but made no difference. I then thought I may have over-thightened the cassette, so I removed the wheel, unlocked the cassette, checked all sprockets were ok, and fitted again a bit more loose this time. Things remained the same, the rumbling noise was still there. The chain looks centred in between the sprockets. What can this be??
thanks
