Steel may be real, but aluminum is actual, and so are the savings in suspension and drivetrain maintenance on Arden's #1FG RSD Bikes Middlechild.

If you're looking for a trail bike that feels like a BMX or dirt jumper than the Middlechild is the bike for you!
Super playful and poppy with the high BB and short 415mm chainstays. Balanced 64.5 degree HTA is good for enduro riding without feeling overly cumbersome in slow speed tech. Also surprisingly supple for an aluminum frame.
Non-tapered headtube (44mm) limits headset choice (can't run an angle adjust headset). Not the lightest.
