FOX RACING SHOX: How to Adjust Your Sag
Finding your ideal suspension setup is key to getting the most out of your ride, and spring rate is arguably the most important piece of that equation. In this video, FOX RACING SHOX’s Outside Technician Louis Angeley shows you how to set your sag to achieve your ideal spring rate.
- Start with 25% sag front and rear.
- You should achieve full travel at least once a ride.
- If you aren’t getting full travel, decrease the pressure in your air spring.
- If your fork is bottoming out excessively, increase pressure.
- Make adjustments in 5-10 PSI increments.
Hi I’m Louis Angeley with Fox and I’m going to help you in greater detail set the sag on your bicycle. You’ve already gone on your first ride and you came back and it’s time to evaluate how much suspension you used. You need to get full travel out of your suspension at least once on a fun ride. This is going to help ensure you’re getting the best ride quality and the fork is being properly lubricated going down the trail.
I’ll have you go ahead and just throw a leg over the bike. Hold just your front brake for me. Now go ahead an hop up on the pedals and just sit on the saddle like you’re going down the trail. Alright, put your pedals level–perfect. I’m going to bounce you around. Now that you’ve settled into the bike, I’m going to reset your sag indicator, just pulling the O-rings to the dust wipers, lift up on the bike, go ahead and put one foot down and step off of the bike. Alright, perfect.
So then we’ll look at our O-rings. 100% travel is just past your Kashima Coat logo, 50%, pretty close to 25%. about ideal there, yeah. 100%, 50, 25, so maybe we’re a little bit stiff in the front. We can make adjustments for the air pressure and change that.
Full travel on one of our forks is going to take the O-ring up to the top of the Kashima Coat logo. If you’re not making it all the way there we need to make air pressure adjustments that follow that. If you’re going through and repeatedly bottoming out on your suspension or the bike was diving or riding low in its travel, we would go ahead and add air pressure to the fork.
Just remove your air cap, and come in with your shock pump, and make a small adjustment. I typically make 5-10 PSI adjustments depending on what kind of results I’m looking for. Adding air pressure is going to make the fork stiffer, keeping you high on your ride height, and keeping you from bottoming out as frequently.
If we found that the O-ring never traveled all the way to the top of the Kashima Coat logo, we’d want to let air pressure out. Again, making small adjustments 5-10 PSI to achieve the adjustment we’re looking for. To make a pressure adjustment you just need to remove your air cap, thread your shock pump on to the shraeder valve until you get a pressure reading on the gauge. Once you’ve got a pressure registered on your gauge, there’s a bleed-off button on the back of the shock pump and you can hit that button to let air pressure out, or a couple pumps to add your pressure needed. You could also add some different air volume reducers that we offer. You can help control your bottom out by adding one of these air volume reducers to give you a desired ride height, and bottom out finish.
