So I'm looking at purchasing a used Trek Top Fuel 110 (2005). It looks to be in pretty good shape with a carbon frame and full XTRs. However, I noticed that the wheelset, front and rear suspension has been replaced and I don't know enough about the components to figure out if these were solid replacements.


Original Bike Components:

Wheelset:
Bontrager Race X Lite ATB Tubeless

Front Suspension:
RockShox SID World Cup 80mm

Rear Suspension:
RockShox MC 3R 80mm


Replacement Components:

Wheelset:
Mavic Crossmax ST

Front Suspension:
Fox F80 Terralogic

Rear Suspension:
RockShox Monarch 4.2

Does anyone have any idea whether these were fair replacements? Or any opinion about these components?
