Giant Fathom Complete Bike
What the checker saysnot checked
No fit check runs on a complete bike, and we will not pretend one does. A complete bike does not fill a slot in the builder, so the checker has no counterpart to compare it against and has never produced a single sentence about one.
$1,500.00 to $1,850.00 MSRP
