I experimented with GX Eagle at some point, but ultimately didn't need a 500% range, as either I could as well push the bike once I needed a 30x50t  on very, very steep climbs or I could reach crazy speeds with a 34 or 36x10t - and I would only reach these on the road realistically, as I just don't launch these gigantic Grand Canyon gaps. Or if I do, there's usually enough "gravity" or slope involved.  But I had to pedal around a gigantic, clanky cassette with a very long cage derailleur and LOADS of chain length.  I went back to my 10-42t 260g XX1 11spd cassette and a 28t on my LT 29er with 11spd Shimano RD. That works for me even on very steep uphills (Alps) and 28x10t x29" 2.5 tires is plenty of top-speed for me. I´d love a 10 or even 9spd version, if durability was noticeably better. But I´d guess there'd be a point where gearing differences become coarse. Manageable but coarse... I don't know if links are permitted on But have a look at: []( I find the drag and drop and customizable interface really helpful for figuring out gearing and comparing different drivetrains and wheel sizes etc.
