French brand Inspyre BMX sent us over some info on their latest project, the new Prototype Race Frame
We work since last August on this project. First we discuss a lot with rider, Jeremy Rencurel and Simon Duchène, they give us lot informations about what they want, then we designed on 2D and 3D. We would like a modern frame and we spend a lot of time on tubing shape.
Our Toptube and Downtube are hydroformed and tapered. The Toptube and Downtube wrap up the head tube to give a lot of stiffness on the front. The tear drop seat tube is also wrap up the bottom bracket (Press Fit BB86 ) to have maximum stiffness at each pedal strokes. Chain stays are 32mm wide and seat tube are triangular to have a reactive and stiff rear triangle. Dropouts integrated chaintensioners and will be compatible in 10mm/15mm and 20mm.
It’s still a prototype but this frame should be in stock in September.
