Review on 🚴 SRAM PG1170 11-Speed Cassette: Optimal Performance and Durability for a Smooth Ride by Dan West

I bought this to have a lower gear on my gravel bike, a different comp with Praxis 48-32 cranks and a long cage Ultegra derailleur and 11 34 Shimano Cassette. These cranks and derailleurs are nominally within the maximum reach of the rear derailleur (34 teeth) and also match Shimano's chain capacity. However, I was able to install it without changing the chain length (i.e. adding two links to accommodate the extra two prongs) or making any other adjustments. The front derailleur easily handles the extended 48-36 length, although the official specs have 2 teeth more than the official specs and the chain shifts perfectly to the 36 tooth sprocket. A pro tip: the 11-34 cassette comes with a spacer that fits between the hub and the largest sprocket on the cassette. If you look closely you will see that the cassette has a cymbal and the spacer removes that cymbal. The SRAM cassette is not concave and does not require a shim. Also, be careful when installing the snap ring. Make sure the cassette is installed with no dust/grit between the sprockets and that the locking ring is fully engaged with the threads on the hub body. It's easy to think the threads are engaged when they aren't and remove the lock ring. Have fun and enjoy your new 5% downshift. The bonus is that gear #2 is also lower than before and good climbing gear too.
