MIDDLECHILD Titanium

(Some components in these photos may differ from the spec sheets. Please refer to the spec sheets below for accuracy)

Update: January 31st, 2021 - Specs & Price Change Notice

Due to the extensive lead times being offered by certain components manufacturers, the original specifications/build kits for this bike have been changed. So that we may be able to deliver complete bikes as scheduled, per our shipping updates, certain parts have been swapped out for those with shorter lead times. In each case, we have attempted to make substitutions that do not compromise the integrity of each build. Pricing has changed accordingly.

Important: Notwithstanding any change of specifications, pricing on all bikes will have to be adjusted to reflect the increases in the cost of manufacturing and shipping. This is unfortunate, but no manufacturer - large or small - will be unaffected by the strain on the global supply chain. We are doing our absolute best to keep our costs and timelines as close to original estimates as possible.

The price changes are effective immediately, and have been applied to all affected bikes, including those on pre-order.

(2020 Build not as shown. this is a 2019 build)

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.
