I built my SC-R55D last week. In this configuration it comes in 7.05kg. I could easily shave more grams off, but I am happy with the weight for now. This morning was my first work out and the bike felt good under me.

Hey Hendie, super cool build, thank you for sharing! AFAIK you're the first person on the english-speaking internet to report building up one of these frames. I was wondering if you'd be willing to share some more info/photos with us, since there isn't a whole lot on Speeder's website. In particular, I'm interested in a head-on view of the fork + head-tube; Speeder's website doesn't have any photos from this angle, even though it's a really crucial area for aerodynamics. I'm also interested in some views of the surface. It looks like you have the matte black finish? Is it that the carbon is clear-coated over, or is it an opaque black paint that covers the carbon, as it appears on Speeder's website? Also, would you also be willing to share any info like build specs and/or frame and fork weights? 7.05kg is mega-lightweight for an aero-disc build, especially with those wheels; I'd be really interested to hear what went into your build.
