larger fork travel question??

cj95

Hi there
I have a 2009 trek 6500 hardtail which currently has forks with 80mm of travel. I have acquired a set of fox forks that have 120mm and hope to transfer these to my trek. What sort of effect would this have on my bike and would it be possible? I know people have put 100mm travel forks on these bikes without any issues before.

Anyone have any thoughts?

Don't do it. It will ride like a barge and will not climb.

The head angle will be 2 degrees slacker as will the seat angle. Your weight will be further back.

A total pig to ride. Sell the forks or the bike and get something suitable.

Pick the front of your bike up so tyre is 40mm from the floor with back on it. Look at the differences, it'll be a fair amount and translate like nick says, probably.

It is possible to shorten some fox forks from 120mm to 100mm-not sure if this can be done for yours though.
