If you’ve been following along on social media and other sites, you probably know by now that TRP looks to be entering the world of derailleurs and shifters sometime soon. Aaron Gwin has been spotted testing various versions of a short cage derailleur for DH, and at Sea Otter this year, there were multiple bikes rolling around with what looks to be a wide range 1×12 compatible rear derailleur.

In the Handkse Gloves booth, Aaron’s new trail bike was sporting an interesting form of drivetrain camouflage with a hefty dose of electrical tape. It doesn’t take much to put two and two together though, as he has been riding on the DH version for some time now. Shown here with an e*thirteen TRS+ 9-46t 12 speed cassette and likely a TRP shifter, this was one of the multiple configurations spotted during the show.

We found another derailleur and shifter on this bike which was set up with a SRAM Eagle 12 speed cassette. Labelled tr12, we’re assuming that stands for Trail 12 speed, which seems to match up with what we’ve seen so far.

The TRP labeled shifter has an interesting pad on the lever – on at least one bike it wasn’t grip tape, but a soft material. Layout looks to be a thumb-thumb arrangement similar to SRAM.

All three derailleurs had a lever up top that seems to be the clutch on/off lever. This tr12 derailleur was the most polished looking with a lock symbol on the lever.

This bike had another interesting set up with a Shimano XTR 12 speed 10-51t cassette and a SRAM X01 shifter and an Eagle chainring.

TRP wouldn’t provide any details other than confirming that they have been testing various stages of drivetrain product. When will we see a TRP drivetrain available to consumers? We’re not sure, but it seems like TRP is taking their time to make sure they get it right.

  1. Cool seeing more companies coming out with derailleurs. Starting look like the 80s again when you had more than 3 companies making drivetrains. Choice is good.

  2. Yeah this is great. I guess with 1 x systems the cost of entry into the drivetrain market has dropped considerably. Develop a rear der and shifter and then partner with any number of cassette/chain/crank/bb manufacturers.

  3. I recently acquired the TRP quadiums. In my personal opinion, I think they are fantastic. Now I’m not a professional rider like the majority of the people that come to this site, but those TRP qualiums are so dialed. I would have no problem trying their new drivetrain.The big boys in the drivetrain world better keep their eyes on this little company.

    • These people are professionals…oy vey for us!

      Kidding kidding! However this TRP thing looks interesting and I hope to see more stuff like it! Even better to see a new US made gruppo even if just shifter and derailleur would be cool to do a full MUSA bike or close to full!

  4. What’s the value proposition here vs. the $107 SRAM NX Eagle rear derailleur?

    If the really want to break into the drivetrain market, there’s an untapped segment waiting for an affordable 12 speed option: Gravel. If TRP offered this with a brifter and matching left brake lever, they’d have people lining up to give it a try.

    • Don’t sram derailleurs all use 1:1 cable pull ratios. This st seastbused to be the case and made it such that you could use mtb cassette and derailleur with a road shifter.

      If you are rich you can also use AXS pieces together. Force shifter XX1 everywhere else.
