Hello fellow cyclists,
I just bought a new Home Trainer that has a Shimano 105 Cassette.
My Bike has an Ultegra drivetrain with less than 600km (375mi). I have checked the wear of the chain which seems clearly well off the .75
Yet I get a clicking/ratcheting sound. Video at slow speed almost no load (hand cranked):
Video at higher speed with bigger load:
What would you do ?
Thanks a lot !
EDIT: With this view, the alignment seems right and an indexing problem less likely ?
Also, it seems the noise comes from the chain/cassette separation on top:
