Targets and a Fast Method<\/h3>\n\n\n\n
For trail riding, aim for 25\u201330% sag on the rear shock and 20\u201325% on the fork. Put on shoes, pack, and water\u2014everything you\u2019ll ride with. Slide the o-ring down each stanchion. Gently mount the bike, stand in a neutral attack position, and bounce lightly once or twice to overcome stiction. Settle still, then step off without compressing further and check o-ring position against total stroke.<\/p>\n\n\n\n
If the fork shows 15% and you want 22%, bleed a little air. If the shock shows 35% and you want 28%, add air. Work in small increments of 5\u201310 PSI on air units and re-check. Coil shocks use preload collars; add or remove a single turn at a time until you hit target without crushing coil bind spacers. Don\u2019t chase a perfect number at the expense of feel; you\u2019re establishing a comfortable ride height, not passing an exam.<\/p>\n\n\n\n
Weight-Based Starting Pressures<\/h3>\n\n\n\n
Every air spring is different, but you can get close by matching PSI to body weight in pounds for the shock, and using a slightly lower ratio for the fork. For many trail shocks, rider weight \u2248 shock PSI is a decent first guess; forks often land around rider weight minus 10\u201315%. For example, at 170 lb in full kit, try ~170 PSI in the shock and ~155 PSI in the fork, then refine to your sag targets. If your frame kinematics are very progressive or very linear, you\u2019ll fine-tune with volume spacers after the first shakedown.<\/p>\n\n\n\n
Rebound: The Speed Your Suspension Returns<\/h2>\n\n\n\n
Rebound controls how fast a compressed spring extends. Too fast and the bike feels nervous, like it\u2019s pogo-sticking; too slow and it packs down, riding lower with each bump and losing travel.<\/p>\n\n\n\n
A Simple Baseline<\/h3>\n\n\n\n
Count total rebound clicks from fully closed (all the way clockwise, gently) to fully open. Start near the middle. For a fork with 14 clicks, that\u2019s about 7 out from closed. For a shock with 12 clicks, start 6 out. Bigger riders or higher air pressures need more rebound damping (closer to closed), since the spring pushes back harder; lighter riders need less.<\/p>\n\n\n\n
What to Feel For<\/h3>\n\n\n\n
Find a curb or parking-lot speed bump. Roll front wheel squarely into it at jogging speed, seated or standing neutrally. If the fork springs back and the front feels \u201cpingy,\u201d add a click or two of rebound damping. If it rebounds so slowly that it stays down over a quick second hit, open a click or two. Repeat for the rear by rolling your back wheel squarely into the bump. The right setting feels calm: one clean compression, a controlled return, and the bike resets before the next feature.<\/p>\n\n\n\n
Low-Speed Compression: Poise and Pedaling Support<\/h2>\n\n\n\n![\"Gravity](\"https:\/\/www.bikesdirect.com\/products\/gravity\/mountain_bikes\/fsx-v-borg-21.jpg\")
<\/figure>\n\n\n\nLow-speed compression (LSC) resists chassis motions that happen slowly\u2014brake dive, body weight shifts, pedaling bob\u2014not the fast spikes from square-edge hits. Think of it as posture, not protection. Adding a few clicks of LSC on the fork keeps your hands higher under braking; adding a few on the shock supports the mid-stroke when you\u2019re climbing seated.<\/p>\n\n\n\n
Good Starting Points<\/h3>\n\n\n\n
If your damper has an open-to-firm dial with numbered clicks, begin two to four clicks from fully open on both fork and shock for typical trail use. On frames prone to bobbing, try one more click of LSC at the shock; on steeper trails with heavy braking, try one more up front. If your bike has only a climb switch, leave it off for descending and flip it on for long pavement or smooth fire-road climbs.<\/p>\n\n\n\n
Volume Spacers: Shaping the Last Third of Travel<\/h2>\n\n\n\n
Air springs can be tuned for \u201cramp-up\u201d with small plastic tokens. If you\u2019re hitting full travel too often even with correct sag and rebound, add a spacer to increase progression so big hits resist bottom-out. If you never reach near-full travel and the bike feels harsh late in the stroke, remove a spacer. Make one change at a time and record it. Forks are sensitive\u2014move cautiously.<\/p>\n\n\n\n
The Ten-Minute Parking-Lot Test<\/h2>\n\n\n\n
Before hitting dirt, validate your numbers where you can repeat inputs.<\/p>\n\n\n\n
Step One: Balance Check<\/h3>\n\n\n\n
Stand next to a wall. Push down on the handlebar to compress the fork and let go; then do the same on the saddle to compress the shock. Both ends should return at similar speeds. If the fork \u201csnaps\u201d up while the rear is sluggish, add a click of rebound at the shock or open the fork a click; you want symmetry so the bike doesn\u2019t pitch.<\/p>\n\n\n\n
Step Two: Slow-Speed Compression Feel<\/h3>\n\n\n\n
Brake hard from a roll. If the fork dives excessively, add a click of LSC. If it stays high but feels skittery on small chatter later, remove a click. Sit and pedal across a rough patch or a painted lot line. If the shock wallows, add a click of LSC; if traction is nervous on tiny bumps, open a click.<\/p>\n\n\n\n
Step Three: Two-Bump Rebound Test<\/h3>\n\n\n\n
Ride straight over two small bumps spaced a bike length apart. If the rear feels lower or \u201cstuck down\u201d at the second bump, rebound is too slow\u2014open one click. If it bucks off the second, it\u2019s too fast\u2014close one click.<\/p>\n\n\n\n
Lock these settings into your notes app with date, PSI, clicks, and temperature. Air pressures drift with big temperature swings, so a cold-morning ride may require a few PSI more than a hot afternoon.<\/p>\n\n\n\n
On-Trail Refinement: Translate Sensations to Changes<\/h2>\n\n\n\n
If the front end chatters on small roots while your hands feel harsh, open the fork\u2019s rebound one click or lower fork pressure by 2\u20133 PSI to increase sag slightly; if it then dives too much, add a click of LSC. If the rear kicks on square edges, close shock rebound one click; if it still bucks, consider one more volume spacer. If the bike feels vague in berms, add a click of LSC to the shock for mid-stroke hold. Make only one change at a time and give it a few minutes of riding before judging.<\/p>\n\n\n\n
Example Platforms That Make Tuning Straightforward<\/h2>\n\n\n\n
If you\u2019re building a first trail bike and want dependable, predictable adjustments, the <\/a>Gravity BaseCamp V7<\/a> offers stable geometry with components that respond clearly to psi and click changes. For riders wanting full-suspension confidence with an approachable setup window, the long-loved <\/a>Gravity FSX<\/a> remains a standout value, easy to dial for local singletrack. If you prefer the agility of smaller wheels with stout control and hydraulic discs, the <\/a>Gravity HD Trail 27.5<\/a> gives direct feedback to suspension adjustments so you learn quickly what each click does.<\/p>\n\n\n\nCommon Pitfalls, Quick Fixes<\/h2>\n\n\n\n
A fork that feels harsh and sits high often has too much air and too little rebound damping; drop 3\u20135 PSI, then add one rebound click if it chatters back. A shock that blows through travel may be under-pressurized; add 10 PSI, re-check sag, and add a volume spacer if bottom-outs persist on single big hits. If both ends feel fine alone but the bike porpoises while pumping, slow the fork rebound one click and add a touch of LSC at the shock to stabilize the chassis.<\/p>\n\n\n\n
Keep It Fresh, Keep It Safe<\/h2>\n\n\n\n![\"Gravity](\"https:\/\/www.bikesdirect.com\/products\/gravity\/mountain_bikes\/grav-v7-lad-turq-3.jpg\")
<\/figure>\n\n\n\nSuspension needs occasional service. If you\u2019re adding air every ride, seals may be tired. If the damper loses clicks or changes feel as it heats, it\u2019s due for a refresh. Wipe stanchions after every ride so dust doesn\u2019t grind into seals, and keep shock mounting hardware snug and quiet. Small habits preserve performance and keep your mountain bike<\/a> suspension setup consistent month to month.<\/p>\n\n\n\nWant Personal Help?<\/h2>\n\n\n\n
