Or, How I Learned to Love not Having a Rear Derailleur Hangar
SRAM has recently released a new drivetrain system called the Transmission type or T type, which promises to be a game-changer for mountain bikers looking for a reliable and high-performing setup. The T-Type is a 12-speed drivetrain that incorporates some innovative features, such as a new cassette design and a unique derailleur system. In this review, we will take a closer look at the SRAM T-Type drivetrain.
Installing the new SRAM T type drivetrain was pretty straight forward. Sram as always has excellent set up videos to explain each of the steps. It does change how you think about the interface between the rear derailleur and the frame however. With the universal derailleur hangar (UDH), the derailuer mounts directly to the frame and uses the thru axle as part of the installation. Without getting into too much details on installing, this integration of the rear frame and derailleur allows the rider to adjust reset the derailuer position if it hits rock or tree on the trail, knocking out of position.
On the bike
I installed the T type drivetrain about 3 months ago and have ridden it regularly at many of my local trails. I have had zero issues with the set up the entre time. I've only experienced smooth, consistent, and accurate shifting across the entire cassette, even under heavy loads and challenging terrain. The 10-52T range provides an impressive gear range that can handle steep climbs and fast descents without spinning out. the new cassette design features 10 steel cogs and 2 aluminum cogs, which reduces weight while increasing durability. It has lived up to its promises of high-performance, durability, and value for money (now that the GX eagle version is available).
The new derailleur has a new pulley design improving chain retention and reducing the likelihood of dropped chains. The clutch mechanism provides a quieter and smoother ride, even on rough terrain.
Performance
The T-Type drivetrain also features an X-Sync 2 chainring that is designed to work seamlessly with the T-Type cassette. The chainring uses a unique tooth profile that improves chain retention and reduces chain wear, ensuring that your drivetrain stays reliable and durable for longer.
The performance of the SRAM T-Type drivetrain has been outstanding.One of my favorite improvements is the new shifter pod with more options to alignemnt on the bars, the two button set up is easy to use and has a crisp detent so you know your shifted. The smaller buttons also make an accidental shift less likely.
Durability
The SRAM T-Type drivetrain is designed to be incredibly durable, with high-quality materials and innovative design features that improve reliability and reduce wear. The cassette, for example, is constructed from high-strength steel and aluminum, which reduces weight while increasing durability. The new derailleur system also features a stronger cage design that is more resistant to impacts and can withstand the rigors of off-road riding.
The X-Sync 2 chainring is another standout feature of the T-Type drivetrain when it comes to durability. The tooth profile is designed to reduce wear and increase the lifespan of the chainring, while also improving chain retention and reducing the likelihood of dropped chains. The chain itself is also designed to be incredibly durable, with hardened pins and rollers that are more resistant to wear and tear.
Conclusion
Overall, the SRAM T-Type drivetrain is a great upgrade to any bike, if you have the UDH on your frame and want the next generation of SRAM AXS MTB drive train. The innovative cassette design, new derailleur system, and X-Sync 2 chainring all work together to create a drivetrain that is smooth, reliable, and able to handle the demands of off-road riding. t-type AXS t type axs
