The elastomers seem ok at first glance but ive noticed that there is a little bit of play when you lift the back end !! i.e As if the elastomers were a bit squashed and not taking up all the float !!
Need to have a good look in daylight. Apart from that it all looks pretty sweet
Nice, very nice.
Your elastomers are probably sacked, as mine were. Check also if the screw is loose. You can put some rubber washers in to take up the slack, and grease the screw with synthetic grease. Petroleum based grease degrades the polyurethane.
Rapid Descent Scotland may have retrofit elastomers for your bike also.
If you are really interested Risse Racing makes a great air shock.
