I just replace the 10 speed cassette on my Mountain bike. I decided to go for a largest cog with more teeth for an easier ride uphill.. I increased from 38T to 42T. I also replaced the chain and chainrings at the same time.
When the bike was on the stand it ran through the gears well. I had the following problem when out riding. I had just ridden up a steep hill on the 22T chain ring and the 42T cassette cog. I had changed down to the second largest cog on the cassette and up to the larger 38T chainring.
When I attempted to change up the gears on the cassette, there was no click resistance on the gear shifter and the chain stayed on the second largest cog on the cassette. I shifted a few more times with no change. I then shifted back down to the 22T chainring and the chain jumped down to the fourth smallest cog on the cassette and the shifter was clicking ok again. I changed back up to the 38T chain ring. However I could not change gear from the fourth smallest cog to any of the other smaller cogs on the cassette. The shifter was at its limit. Also noted that when changing down to the largest cassette cog again, there was an additional click on the shifter once the chain was in place on the cog, this appears to move the cable a little but does not affect the chain.
Further info is that the 'B' screw is at its limit for getting the required clearance between chain and cog.
Any suggestions. The whole of the chain drive system is Shimano. The 10 speed 42T-11T cassette is according to Shimano is compliant with all Shimano 10 speed systems.
