To properly set-up your Turner’s air shock, first find your ‘Ready-to-Ride weight’. Your ‘Ready-to-Ride weight’ is how much you weight with all of your riding gear on, that includes helmet, water and spare tube as well.
Remember, if you change your gear, you’re changing your ‘Ready-to-Ride Weight’.
TIP: You should check the air pressure in your shock and fork every 6-8 weeks! They will lose air pressure over time, don't let that impact your ride quality.
To start, make sure the compression and rebound settings are fully open.
Find a stable surface to lean on, then mount your bike with all of your riding gear on. It may help to lower your seat slightly so you can easily reach the ground while sitting. Then bounce a little, just enough to engage the shocks travel.
While sitting, carefully reach down and slide the O-ring back up against the wiper seal and smoothly step off of your bike. Try not to engage the shocks travel when dismounting. Then measure the distance between the shocks O-ring and wiper seal. Check the chart below for the appropriate Sag Amount for your Turner model.
Next add or remove air and re-check the measurement of sag using the previous steps until the proper amount of sag is accurately achieved.
Now dial in the rebound adjuster a few clicks at a time while 'bouncing' the bike. When it is visibly slowed down take it for a test ride and re-check the rebound setting. You want to feel the damping control the rebound but not so much that the rear starts to pack down on successive impacts.
Tip: Be sure to write this psi amount down to make it easier to check air pressure in the future.
The amount of front and rear sag effects BB height and handling. Try plus or minus 2mm of shock sag, and plus or minus 5psi in the fork to custom tune your Turner bike.
Check with the fork maker for their suggested sag/pressure settings.
