Bike Configuration: 1 x 9 11-42 T Rear Cassette Installation
Hi Everyone,
I was hoping someone could help me with this bike configuration question. I currently ride a 1 x 9 system with largest cog on my rear cassette being 26 t. I wanted to upgrade my rear cassette to help with some killer hills. I was looking at a microshift advent 11 - 42 t rear cassette, however my current shimano derailleur doesn't provide enough slack to reach the highest cogs. Therefore, I was going to buy a new derailleur, and I can't figure out which one to get. Since its a single front chain ring, some people say I can get a 9 speed medium cage length derailleur and be fine. Microshift makes a derailleur for this gear set however, I have shimano shifters and don't know if they will play nice. Any advice on this would be great. I don't mind replacing the rear gear set and a derailleur but also a shifter, seems a little crazy.
Thanks,
Dan

Microshift Advent also make a derailleur for that cassette, so problem solved there. The only issue is the shifter. I don't know if your shifter has the same pull ratio as the flat bar shifter Microshift makes. Someone with more knowledge than me can chime in and tell you if it will work.
A long cage 9 speed derailleur will handle 36 teeth if you are lucky. You may have to do a B screw hack for this one.
Others may have different solutions which will be good to read about. Good luck.

Put a wolftooth roadlink on it. If that doesn't work pick up a cheap 9 speed shimano mountainbike RD and try that. Those are rated to 36 so might still need the roadlink.

Thanks everyone for the reply.
I found this derailleur. I cant link it because I am new to this forum.
Now, I need new shifters it seems. I currently have drop bar shifters, unfortunately the ones I need are expensive and out of stock.
I wonder if any other drop bar shifters are compatible, is there a metric like the pull ratio that could be compared?
