The DTC certificate allows you to completely rebuild your front. This means: fork bridges, fork bars, brake system, stub handlebars, rims, tyres
The second DTC certificateallows you to remodel the frame. You can use it to shorten the frame, remove the knot plates, insert a strut for seat fastening and adjust the strut bracket.
