MIDDLECHILD V2 Titanium
As is the all-too common scenario industry-wide lately, we have received unfavorable updates from suppliers regarding some key components on our bikes, which have been delayed in manufacturing. Despite recent snafus, our frames are essentially on schedule, aside from possible shipping delays. We have taken all of the necessary steps to minimize these delays, but as we’ve just learned with the Mayor v5 and MiddleChild shipments, we are at the mercy of global forces and circumstances beyond anyone's control. See new date above
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.
(2021 Build not as shown. this is a 2019 build – See specs below for complete build details)
Estimated Delivery – April 30th to May 15th, 2021 – NEW – Frames are on time. Complete bikes are delayed to July 2021 (See latest update above)
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 Maxxis Minion DHF & DHR II 2.8 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.
