Herman Braun track bike (Van Tuyl livery)

This is a very well made example from the 80's (1986?). The build quality clearly shows when you look up close. Tubing is unknown, but I hope they still have serial number archives in Spijkenisse with more info. The frame has been painted in Van Tuyl livery, probably a sponsor thing. Also decals of the Nijmegen based team Groenewoud are on the frame. Previous owner told me a Groenewoud rider won a national title on this bike back in the day (time trial).

Braun started as a mechanic (aged 16!) in the successful teams of Kees Pellenaars and later Gazelle-Vredestein. He started building frames in the early 80's and quit his job as a mechanic in '86.
Herman Braun still builds high end custom steel frames together with his son. On their website, there's a lot of interesting info on modern steel frame building among other stuff.
