Hello All to our Respected Riders, A few years ago, rumors began circulating that SRAM would completely phase out cable-actuated derailleurs from their lineup. At the time, it felt unlikely — but as more frames started appearing without ports for derailleur housing, the speculation began to seem more credible. Fortunately, those rumors proved false. The recent release of the Eagle 90 and Eagle 70 drivetrains confirms it — both are cable-actuated systems, free of batteries.
These new 12-speed drivetrains draw heavily from the design of SRAM’s wireless Transmission series, including the Full Mount interface, where the derailleur wraps around both sides of the frame instead of mounting to a traditional hanger. If your frame supports a Universal Derailleur Hanger (UDH), it’s likely compatible with the new mechanical Transmission derailleurs as well.
At MTB WANDERERS, we’ve always believed that mountain biking should be simple, rugged, and built for the wild. That’s why we’re stoked about SRAM’s latest drop—the Eagle 90 Mechanical Transmission. This isn’t just a rework of older tech—it’s a full-fledged mechanical comeback, reimagined for today’s hardcore trail riders and adventurers.
Let’s dive deep into what makes the Eagle 90 mechanical groupset a game-changer—especially for riders who value performance without the wires.
1. A Refined Mechanical Comeback
SRAM’s new mechanical Eagle 90 lineup is inspired by the precision and strength of AXS, but designed with the simplicity of cable actuation. This is not just a side project—it’s a fully modernized groupset for riders who don’t want to worry about battery levels or firmware updates.
With better durability, smoother shifting, and easier setup, the Eagle 90 is made for those who like to ride hard and wrench smart.
