Must be an optical illusion. It is on a freewheel with gold spacers. Perphaps this photo will show it better

I rescued this frame from a display rack at a LBS in Cheshire. It had a few marks from handling but had never been built up.
It's a Kinesis Decade Virtue - one of the first made before FELT threw their toys out of the pram and made Kinesis change the name to Virsa, as they had a bike with the same name.
It's quite a rare beast - especially as they suffer from cracking seat-tubes, partly due to the supplied QR seatclamp clamping on the seatpost but not the frame, but also people running on a minimum length seat-post (To counter I'm currently running an uncut 350mm seatpost, plus that big massive double clamp)
Out of the 10 made in this particular size and colour, it would be interesting to know how many are left. I've only ever spoke to two other owners of any size or colour, and one of them works for the original supplier (Upgrade) who says his dad still rides it.
