So, after a few months where life(tm) got in the way of riding I got out on Trance this weekend to find that the Giant Contact dropper (came with the bike) won't fully extend when the switch is flicked - it gets to about 4-5cm from full extension, kinda like the Trail position on the Fox DOSS. I can fully extend it by holding the switch down and manually pulling it out. Any thoughts on how it can be fixed?
Hey,
I had similar issues with mine. It ended up just needing the cable adjusted.
If you manually need to pull the seat up the last couple 40 -50mm it probably means the cable is too slack. You should have a barrel adjuster on your bar lever. The further it's unscrewed the more tension is on the cable. Hopefully it just needs a tweak to get it running right.
If there isn't enough play in the barrel adjuster you can tighten the cable under the seat by taking the seat of, loosening the grub screw (2mm) and using a pair of needle nose pliers to pull the cable through another few millimetres or so and re-tightening the grub screw.
Hope that helps...
In saying this, if it's a new bike take it back to the LBS and get them to adjust it.
Edit: to check if it's a problem with the gas strut, take your seat off and manually pull the lever located under the seat all the way back (imitating the same action as to if you were going to raise the seat using the bar lever). If it goes all the way up you know its only a cable issue. If it still only goes halfway up you are probably out of gas...
