Titanium On One single speed cyclo crosser (1 of 3 (I think) built), but I always ran it as a fixed. I know where this one lives now, but I've never come across the other two!
My '90 Klein Pinnacle with a fantastic paintjob. I've converted this Pinnacle to a comfortable city cruiser with a big wide steerer to sit more upright. The big white tyres really add comfort and a 36/18 ratio makes it perfect to cruise around the city. Altogether the bike is light, fast, gets much attention and is a joy to ride I use it a lot for practically everything...
