[QUOTE 3597739, member: 9609"]I will do a sideways shot later - I would have thought wear would be noted from how pointy the teeth are - hence loking at my cassette I would have thought in order of use would be 1st, 3rd, 2nd, 4th with 5th and 6th having little to no use, & 7th is as pristine as the day it was made.
As for cross wear with the chain ring, I would have thought 95% of my peddling was in the first three gears whilst in the smaller chain ring which is shown in the image. - so if cross wear is evident, could something else be misaligned ?[/QUOTE]
Cassette teeth don't go pointy with wear unless really worn out like your low gear, but chainring teeth do. Cassette teeth develop long flat valleys (roots) and when viewed from head-on, the wear pockets are distinctive with sharp edges and discoloration in the roots where the chain contacts.
Cross chaining happens even when in the small chainring and large sprocket. You just can't have a good chainline everywhere. I doubt there's something wrong elsewhere, it is just indicative of which gear combinations you use.
