Back at the beginning of May, I had a weekend of frame repairs! SB4409 had new transfers and a bit of clear coat, while SB6560 had new gear lever bosses brazed into place. Before I tidied up and put the files away, I thought I’d squeeze in one more project; SB632. This is a special little frame that has had a modification at some point in its life to add a gear hanger and increase the thickness of the rear track ends to accommodate road wheels and gearing. This is the first step to restoring SB632 back to how it was originally.
This is post number two looking at new arrival SB632, and I’m measuring geometry. How will this frame measure up? What size is it? How long (or short) is it? What angles does it use? What is the bottom bracket height? Does the fork clearance affect the frame geometry and size? More importantly, will the geometry give me any clues to enable me to pinpoint what this frame is? Lots of questions needing lots of answers!
Oh, and this is also my 100th published TI-Raleigh SBDU blog post! A small milestone that I’m very proud of.
I’ve had another new arrival, not long after the 753 Dynaflite came into the workshop, I’ve found another rather special frame that just deserves to be in the collection. SB632 is much smaller than anything I would normally collect, but the significance of this frame meant I had to have it.
