Sonder Transmitter NX1 Recon review - MBR

Jul 2019 · Alan Muldoon

With slackest head angle, longest reach and shortest stem, the Sonder Transmitter is built for bombing, inspiring confidence to fully attack descents.

Highs
  • Great on the descents, quality Love Mud own-brand kit, fast freehub engagement.

Lows
  • Feels vague on flat trails, long fork causes extreme geometry changes on choppy terrain.

Sonder Transmitter NX1 Revelation review

Jun 2019

The Sonder Transmitter in this NX1 Revelation spec is an aluminium trail hardtail with impressive geometry and some good looks, with some obvious thought put into the frame. It is beaten by other bigger brands when it comes to value though, leaving us to make a decision between aggressive geometry or better parts.
