Here is my 650b in the fixture. This was a project I started out with in may last year, but due to a number of things it was put on hold until now. It’s designed around a 130mm White Brothers fork and the frame is a mix of Columbus Life and True Temper OX2 tubing. The seat tube is a 35mm Life top tube with one butted end removed and sleeved to take a 31.6mm seatpost (to be able to run a Crank Brothers Joplin quick adjustable seatpost for long descents in the Alps or the Sierra Nevada). Geometry is a 69 degree head angle matched with a 73 degree seat angle. This is a degree steeper than I usually like to build my frames, but due to the 20mm set-back of the Joplin post I end up sitting in almost the same sport. That means that I need to dig up a rigid post with 20mm set-back as well.
I did finally find some time to finish up this Rocky Mountain Blizzard that needed to be updated to disc brakes. A fairly standard operation by now (I must have done nearly 20), but this one had a small variation that I tested on a beater bike a while ago. Instead of using new hose guides on the top tube, I opted for a solution where the cable guides that where once for the brake cable is drilled out and then the slot is brazed up. So in other words it’s just turned into a tube. A wee bit of work, but it’s worth it. Especially on a frame like this where the original braze-on is of the two-cable kind.
There’s a few other things happening in the workshop as well. I’ll try to post that later today.
