The ERA CF is Inspyre's flagship carbon race frame, built around precision, stiffness and dynamic comfort rather than chasing the lightest number on the scales. The result is a natural, smooth and precise ride, a frame that works with you rather than one you have to adapt to.

This ERA Pro XXXXL Frameset is built for BMX racing, coming in with a 23 inch top tube, it's suited to riders 6 foot plus, or anyone who like a long set up for stability. Long enough to fit a Suzuki Hayabusa donk in the front, this big dawg is perfect for putting together a new race build from scratch and lighting up the first straight like a holeshot king.

Key Features

• High-modulus Japanese carbon fibre, selected for consistency and an excellent stiffness-to-weight ratio
• AXC (Advanced Composite Carbon) layup: layer structure tuned for front triangle response, with fibre orientations that keep control without excess stiffness, so power goes straight to the track
• DualYoke architecture: the BBYoke stabilises the power base while the TopYoke stiffens and aligns the rear triangle, for controlled, predictable handling front to rear
• Axial dropouts with 35mm of adjustment to fine-tune your wheelbase, plus an integrated chain tensioner adjusted with a hex key
• ADS (Adaptive Drive System) ready: keeps your wheelbase consistent regardless of gear ratio (optional, sold separately)
• Fully guided internal cable routing for a clean brake hose run
• Flat mount disc brake for a 120mm rotor
• Available in Chameleon with Black, Black Gloss with Brushed Chrome, or Stealth Grey with Black
