Middlechild Aluminum

MIDDLECHILD Aluminum

There’s one in every family. That one that feels excluded from the bunch. If you’re down with that attitude because you like to go your own way, then we’d like to introduce you to the rowdiest member of the RSD family – the MiddleChild.

Some of our bikes are great at getting the job done – real authorities. The 29/27.5+ MiddleChild gets it done, but the only thing on the agenda is playtime. Every detail on this premium-quality handmade AL frame screams “skip work and let’s party!”

  • double-butted, heat-treated 6000 series aluminum tubing
  • full CNC-machined custom yoke that’ll take 2.8″ tires (or up to 2.6″ x 29)
  • 64.5 degree head tube and 74 degree seat tube angles paired with 140mm fork –  that aggressive geometry for both climbing and sending choice descent lines
  • boost spacing and short chainstays (adjustable from 415mm – 430mm) for super stability and loads of confidence in the rough stuff
  • Choose from either Duroc 40 27.5+ wheels with Nobby Nic 27.5×2.8 Addix SpeedGrip tires or Duroc 35 29in wheels with Maxxis Minion DHF 2.5 Front and Aggressor 2.5 Rear

The MiddleChild is a purely new-school ‘Enduro’ hardtail…

…that will never get left behind.
