Description

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.

Developed in collaboration with the Inspyre pro team, this frame wasn't just drawn up and put into production. Inspyre commissioned several prototypes which the riders rode, and raced, providing feedback and suggestions to the frame's designer which resulted in this, the finished product.

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
