Just changed my Shimano 10s cassette from a 11 36 to a Sunrace 10s 11 46. Also changed Shimano Deore 10s M610 RD to a Shimano 11s M8000 11s RD to cope with the 40t & 46t sprockets. Gear changes are smooth as a babies bum with one exception. Changing from either 8th or 6th gear to 7th gear results in a rough changeover and pedalling in 7th gear is noisy and not smooth, almost as if the chain has not engaged properly. Before making these changes I had read plenty of information where this had been successfully done with no issues. I also contacted at least a dozen bike shops to get their opinions. No negative feedback at all. I'm wondering if the LBS, which is basically a hobby for a competition rider, has not made all the necessary adjustments for smooth changing in all gears. Also his knowledge base is more road bikes than MTB's. He did mention when he competed the changeover that 1 gear would give me problems. I was surprised by this as none of the people who have made the same change said they had encountered any issues at all. Does anyone have any suggestions on how I can have this one glitch rectified. BTW I'm riding a 3x MTB.
