2021 MIDDLECHILD Titanium

(2021 Build not as shown. this is a 2019 build – See specs below for complete build details)
Estimated Delivery – April 30th, 2021

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 steel frame screams “skip work and let’s party!”

  • Titanium 3AL 2.5V Butted and Heat Treated
  • 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.
