Need some info here. Whats the diff in Fatbob tress compared to FXDC trees are wideglide trees... Rake diff, wider are what..

 

The FB trees are wider... same as the WG trees.
As to the 'rake'... most (if not all) of it is in the frame.
Some trees are made with (up to) 3 degrees of rake added, but I'm not sure if the WG trees are such as those.

 

Fat Bob trees are the same width as the Wide Glide trees. FB trees have 0 degrees rake built in them. WG trees have 2 degrees.
