Individual components for this groupset are available but not as a complete set. It’s an affordable 12-speed system that is much more approachable than more expensive options, but still boasts a wide gearing range. SRAM’s SX Eagle groupset is mainly found on new, lower-end bikes. SRAM says its Eagle technology is lighter, simpler, and more robust, and offers a 520% gear ratio that aligns with the range of 2x setups.įrom bottom to top, here is a rundown of the hierarchy of the SRAM Eagle mountain bike ecosystem. While components for those systems are still available, SRAM shifted all-new bikes to the 12-speed Eagle system. In the past, SRAM offered 11-speed groupsets across its SX, NX, GX, X01, and X11 drivetrains. With a range of interchangeable components spanning from complete groupsets in the $400 range up to $2,000 (or more), SRAM offers a path to mix and match elements that can help dial in cost and performance needs for every rider. The latest iteration of SRAM MTB tech, the updated SRAM Eagle ecosystem, is no exception. Steadily progressing for decades, SRAM groupsets shrugged off convention to reimagine drivetrains in ways that make them easier to use and less cumbersome than earlier technology would allow. SRAM mountain bike groupsets are everywhere and can look considerably different from bike to bike. The TZ and TX Tourney groupsets also include brake levers, freewheel/cassettes, bottom brackets and cranksets and are all compatible to upgrades up to 1 or 2 components above in the Shimano MTB hierarchy.Whether evaluating a new bike or planning to upgrade one you already own, you'll need to understand the various component specs.
They come with a thumb and index shifter levers for up and down shifts. The RapidFire shifters are the most popular in not just Tourney but all other MTB/hybrid gearing components. Grip shifters or Revo shifters as they are popularly known are the first kind of shifters seen on Tourney groupsets, though they are easy to use the maintenance and repairs are complicated. Both the TX and TZ derailleurs can be found working with 2 types of shifters, grip and rapid fire. Minor design adjustments are made in these to improve gear shifting speed. Shimano’s TX series derailleurs are one step above the TZ in terms of build quality. But if you are looking for regular commuting and/or occasional flat trail rides then these components are perfectly suited for such bicycles. These gears when in use doesn’t feel the smoothest and will need tuning from time to time. The TZ series was released first in Tourney and most commonly found as 3x7 Speed combinations. The Shimano Tourney TZ series groupset are found in entry level Hybrids and MTBs.
