Hey folks I’m riding a Decathlon Riverside Touring 920 with a SRAM Rival 1×11 drivetrain and a 32T front.
Current cassette is 11–42.
My problem: on long, loaded climbs with bags/bikepacking gear, the current range just feels too tall and I’m struggling. I’m thinking about options to gain easier climbing without going full 2×.
Some perhaps too specific questions:
-
Has anyone ever run a cassette up to 11–50 (or similar large range) with a SRAM Rival 1×11 setup?
-
What combo did you use (brand/model cassette, chain, derailleur adjustment) and how reliable was it?
-
Did you need any modifications (B-screw adjustment, derailleur hanger alignment, longer cage, etc.)?
-
How were the shift quality and chain tension — especially when loaded and under climbing torque?
Anyone with I need real experience, not speculation. The goal is to be able to climb loaded without running out of easy gear — and I want to know whether this combo will actually run before I invest. Thanks!
Biketax shot included 🙂 cheers

I have the same bike
No. Its rated for 42t cassette.
You can push it past to 46t, ive done on a couple bikes with success but be warned its beyond srams spec. Ymmv.
32:46 is a crazy low gear. If you bottom out that, you are better off walking/pushing, we all been there.
What you can do is get a 12s shifter cog replacement to make it 12s eagle compatible, then get an eagle rd and cassette and chain. Saves you on replacing expensive shifters. https://ratiotechnology.com/product-category/upgrade-kits/
Probably not, I would run a mullet setup with a Eagle derailleur, problem solved.
Solution: smaller chainring
Get the Ratio Technology cage for this and you can run up to a 52t cassette. I’m running a rival rear mech, this cage, and a Shimano 11-51 11speed cassette. Works great.
I run a Sram Rival 1x RD that I Frankensteined to work on an 11-50T 11s Srunrace cassette. I did have to “harvest” a Sram NX Eagle derailleur cage that I found off facebook marketplace to do it. Here’s a link. I hope this answers your inquiry:
