Holy ducking ship..no messing about here then. Did you have donor bike..so like used the parts of your sons previous bike?..Also who does the building side?
HaHa! Yep, no messing! Built in 4 hours, 1 hour was cable routing! The Donor bike was my Sons Vitus Sommet 1. The Vitus frame is now going to be built up by my younger son with his parts. On this occasion, i let my son do most of the building, i just did the fiddly stuff like feeding rear brake through the internal routing and bleeding etc.
