That 7-speed 13-42 cassette

[J Schwartz]

Greetings 

Is anyone using that "Jim" cassette and, if so, are you pairing it with a double or going 1x?

How's is working for you?

Thinking of using it 1x for a townie / grocery getter Chev.

thanks

Hello. I recently built up my Gus with the 11-36 version of the 7 speed cassette paired with the Silver wide/low crankset. The jury is still out but so far so good. The steps of course are bigger than the 9 speed cluster on my Clem. But, I’ve enjoyed the shifting performance and simplicity while never wanting for a gear - yet. The proof of concept will come this week (I hope) when I finally get to put this bike to the test at my favorite trail - DTE in Chelsie, Michigan. This is a 22 mile rollercoaster with quite a bit of climbing & fast, accurate shifting is mandatory. Any other forum than this one and I would no doubt get ridiculed for this; last year I did this trail regularly on a full suspension Carbon bike with 1x12 AXS shifting. I fully expect to be slower but much more comfortable. I cannot imagine the 7 speed not being very good for your application.

Hello Jason,

If this helps, I have the 13-34 Jim cassette paired with a 46x34 crank, Deore LX rear der and a Claris in the front. Friction shifted. Works just fine.

Best,

Rich in ATL

For a few months now, I've been using the 13-42 on my Clem with the stock 38/24 chain rings. I've rarely switched to the 24, so if I were setting it up again, I'd be comfortable using it as a 1x.

90% of my use is hauling kids over small hills in SF, and a bit of trail riding.

I'd say it could be great for your use case too!

Hi, Slin - did you need to use a derailleur extender with the 13-42 cassette? If not curious how well the front 24 and rear 42 work together. Maybe this has more to do with what a particular RD can handle/wrap.

Thanks,

Scott

Scott -

For my derailer, yeah, I needed an extender to use the 42t cassette, but with the extender it worked great, even in 24x42, and 38x42. in 24x42 it was very very spinny, I probably have looked down to check it the chain came off before.

I am using the 42 jim on an old stumpy, w and 36-24 up front, and on a gus, w a 36 1x. it rules and i will be adding one to my 650b rb 2 eventually. i am using a wolftooth road link on both, not the best looking but doesn't wreck the look of either bike.
