i recently rescued my brother's trek 8000 in order to revive it. i need to replace the brakes (cantilever, some parts are cracked) and it should be good to go. this is my first bike using a suspension (only front) and i had some questions about the springiness of it. it seems the slightest pressure causes it to go down, getting on the bike, and especially braking causes the front of the bike to dive a lot. how do i go about making it stiffer? some searching lead me to believe that it is an air/oil mixture. should i replace the mixture completely? (this bike pretty old and has been sitting in a shed for some time)
thanks.
thanks.
