Converting an "old" Lightening to a more efficient touring bike.
A fellow recumbent rider I know has an older model Lightening. He wants to upgrade it so it can be a better touring bike. For part of this he wants to put disc brakes on it. For the rear it really isn't a problem.
But the front is a bit of a challenge. It has a 17" wheel. The fork won't accomidate a 20" wheel & he doesn't want to use a 16" wheel. So that leaves changing out the fork entirely. But the problem with that may be the diameter of the area of the frame that receives the top of the fork tube, (I don't know the correct terminology). Because there may be a difference in the diameter from the original fork to a new one that will accomidate a 20" wheel he may not be able to change the fork.
If, because of a possible diameter problem that may prevent the fork form being changed, does anyone have any possible solutions? Which is the most common problem with diameter size? A new fork is to large of a diamater or to small? If it to small will shims work to take up the excess space?
