NO. Now, my cassette shimano 9 speed started working wrong It should have--you have 10sp shifters. , so I'm thinking to change it for a Deore 11-36 10 speed. That will work, depending upon capacity of chainrings. taking in to consideration that I'm riding in average 150k per week, Is that decision ok?
Thanks.
