Donor triangle attachment
A couple of basic questions - I think i know the answers but want to be sure.
1) The attachment point of the donor rear triangle in the rear dropouts of the bike to be extended:
Am I right in thinking that you can do this by leaving the bottom bracket in the donor rear triangle, and swapping the crank arm attachment bolts for (much) longer ones of the same thread, and filling the excess space between dropout and triangle with washers? Or is there a better way? Maybe just using one long bolt, removing the BB on the donor triangle... but then what do you use to centre the long bolt in the donor triangle BB shell?
2) My proposed bike to be extended does not have a kickstand bridge between the chainstays, but a small bridge for mudguard attachment with the hole going front to back. Would this be robust enough for the bracing strut to be attached. Would I have to use a slight smaller diameter strut with maybe a thicker gauge?
Thanks in advance and apologies if the questions are completely idiotic.
