SRAM’s Transmission drivetrains are becoming an increasingly common sight, both as original equipment and via aftermarket installs. Today’s release should make those OE builds even more accessible, with a new budget-minded series of T-Type components that slot right into the broader family. Simply dubbed S-1000, this gruppo includes a derailleur, cassette, and crankset – all optimized for price, while still retaining compatibility with upgrade parts from the higher end groups.
Additionally, there is an S-1000 e-MTB crank in the lineup as well. With fitment options for SRAM, Brose, Bosch, and ISIS splines, they have an identical form factor and finish color. Length options for the e-MTB cranks are 150-170mm, in standard 5mm increments.
Built with the same architecture used on the T-Type GX derailleur, the S-1000 variant cuts cost in one key way, while remaining upgradeable down the line. The main (and perhaps only) difference between the two comes down to the clutch mechanism, with the S-1000 using a “drag spring cage damper” as opposed to the higher quality friction damper found in all other T-Type derailleurs. Luckily, the interface is identical and fully serviceable, so you’ll be able to upgrade the clutch or entire lower cage assembly should yours wear out.
The XS-1270 cassette houses all the same shifting profiles that the higher-end T-Type cassettes use, but with a different driver body interface and a more traditional construction. The 1270 mounts to standard HG driver bodies (steel only), and can be replaced in segments as those teeth wear. This cassette will work with all T-Type chains and components, but there are some details to keep in mind should you want to upgrade to a higher-end cassette down the line.
Since all other SRAM T-Type cassettes use the XD driver body mount, you’ll need to swap your wheel’s driver body to be able to mount those nicer options. Not an immediate consideration, just something to keep in mind.
