MIDDLECHILD Titanium
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.

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.

How much assembly is required?
As stated in the Shop page under each product, there is around 50% assembly required. Each bike takes approximately 30min to 1 hour for an experienced mechanic. Assembly should not be attempted if you’ve never done it before. A bike that is not properly assembled could result in potential serious injuries. Take it to a shop near you. https://rsdbikes.com/assembly-requirements/
Do Bikes, Frames or Forks really cost $100, $250 or $500?
No, the $100, $250 or $500 is a required deposit in order to secure a specific size, colour or build that is currently not in stock. The balance will be due prior to shipping. These amounts are labelled as Deposit or Pre-Order Deposit
When do I pay the balance after i placed a pre-order?
Once the pre-order is placed and the deposit paid, there are no further actions needed from you. We will contact you 2-3 weeks prior to the scheduled delivery to confirm your shipping information as well as the details of your order. Once all is confirmed, we will send you an invoice for the balance. We DO NOT automatically charge the original card used for the deposit. The balance can be settled with the same or any other cards.
After I placed a pre-order, can I pay down the balance before the bike/frame arrives?
yes, we accept partial payments to increase the amount of your deposit. The full balance has to be paid prior to shipping. should you wish to make additional partial deposits, please email us. info@rsdbikes.com and reference your order #
Can your frames accept tapered forks?
Yes, all of our frames use 44mm Straight Head Tubes. That means that you can use any and all steer tubes styles and sizes. When the Headset is provided with the frame, it is for tapered steer tube forks.
What headset do i need?
We use ZS44 Top (Zero Stack) and EC44 Bottom (External Cup). We also only use tapered steerer tube forks.
What are the crank specs for the Mayor?
BB shell is 100mm Threaded.
You need a 190/197mm rear spacing crank with a minimum 100mm clearance from the center of the BB to the inside clearance dimension of the crank arms. Minimum Q Factor is 220mm.
We recommend any of these Race Face 190/197mm cranks: Next SL, Next R, Turbine, Aeffect and Ride. Each of these crank will come with 2 x 11mm spacers.
SRAM cranks, even though 190/197mm DO NOT FIT. The Q Factor is too low and therefore the crank arms will not clear the stays.
Do you have a size chart?
Yes, in 2 different places. One is located mid page on the Specs & Geometry Tab as a pull down menu. Just extend the (+) to see the Chart. The other is located at the bottom of the Geometry chart which is also mid page and locate the pull down menu (+) for the Geometry chart and choose your preferred standard: Imperial or Metric.
What’s the biggest Tire/Rim combo I can use on:
Some tire/rim combo may differ from brand to brand and from year to year, so please use your discretion. These are only guidelines.
- Mayor V3 / V4 / V5 – 26×5.05/100mm. 27.5×4.0/50mm, 29×3.0/50mm

Can I customize my build?
Yes and No. We might have some parts in stock. Depends on availability. We only have access to other parts from the manufacturers we currently work with, It also all depends in their available stock. If it’s a brand we never worked with, then sorry, we can’t.
Do you offer custom geometry?
No, we don’t. We designed each of our bikes from the ground up to be produced in large quantities, so we cannot accommodate single designs.
What is your warranty?
Is my warranty void if I drill my own Internal Dropper hole?
Yes, it will be voided. Each of our frames are tested as sold. If the frame is altered in anyway, it could compromise the strength of the frame and therefore void the warranty. See the full Warranty details here
Can I convert my bike to an e-bike?
Conversion to e-bike, regardless of the system, will void your warranty.
