The Radavist

Totally no big deal if you’ve got better stuff to do, but if you wanna read about “Powertrain,” SRAM’s first-ever E-MTB motor, Travis wrote this post. Like, he didn’t ride it or anything, but it’s big news, and we figured you might want to know about it. He talks about stuff like the different modes and how the buttons work and a thing about auto-shifting. No rush, though. The post will just be sitting here. So if on, like, Friday night you’re, like “Oh yeah, that SRAM e-bike thing…” and you haven’t read Pinkbike’s review or whatever, just come on back. But again, not a huge deal if it slips your mind…

Amid the circus of Trojan hangers and load-bearing derailleurs, few of us paid any mind to SRAM Transmission’s humble front chainring. All it got was praise for its two removable bash guards, and scorn for its eight-bolt interface. But the T-Type chainring reflects some fascinating choices. Choices that prevented you from using any competitor’s chainring, and by extension, any competitor’s crank … until now. Wolf Tooth recently released Transmission-compatible chainrings that can be paired with many common cranks. Travis Engel talks about why that matters, even though his Cane Creek eeWings aren’t exactly common.

When you review bike products, sometimes they arrive with some swag. T-shirt, stickers, sure. But sometimes there’s a cool memento, like an Abbey Tool laser-etched by whatever brand has partnered up with them for the launch. Or an artifact from the product’s manufacturing and development, like a piece of the innovative raw material that made it possible. But what came with my GX Transmission kit is by far the most moving party favor I’ve ever received.

At the time of publishing this, the ink is still drying on our first-impressions of SRAM‘s debut boat-rocking direct-mount, electronic-shifting drivetrain concept, dubbed “Transmission.” Ever since, it’s been hard to get into a conversation with a bike nerd without Transmission coming up. Travis Engel is one of those nerds who can’t stop talking about it, so he was the perfect person to cover the surprise addition of a lower-priced GX group, which launched today. Read on to see what changed, what didn’t, and why this is such good news.

After months of leaks, spottings, and speculation, SRAM unveiled their newest wireless mountain groupset, Eagle Transmission, along with a collection of Stealth Brakes. This hefty product launch encompasses derailleurs, cranksets, cassettes, shift controllers, and more across XX SL Eagle, XX Eagle, and XO Eagle levels along with power meter and e-bike-specific components. SRAM also released an all-new Stealth lever body for their Level and Code brake lineup. As such there’s a lot to unpack here, which we expect to dive deeper into during the next few months of Transmission-equipped bike reviews. Today, however, let’s take a look at product highlights and some initial thoughts about these new components after a few rides on a Santa Cruz Megatower test bike that SRAM sent us a couple of weeks ago.
