It's the end of summer; how's your squish?
Your suspension is arguably the most important system on your mountain bike. It's what keeps your wheels tracking the ground, gives you control, and enalbes you to ride the good stuff. and like other parts of your bike, it needs regular service to keep performing the way it's supposed to. Both ends need it too; front and rear suspension both wear the same way, and both need love.
Performance differences show up on the trail but not all at once. Your bike might start feeling rough, sticky, or harsh over chatter and small bumps, or you might find you're just not riding as well. That might be your suspension telling you it needs some attention. Usually this happens well before anything actually breaks.
All these parts have recommmended service intervals just like your car. Typcailly 50 hours and 150hrs for shocks and forks. Most people don't actually track hours riding on their bike (an app like Strava can help if you want real numbers), so it's easier to think of it in terms of a season of riding. At roughly 1.5 hrs/week, April through October, the first service interval (~50 hrs) lands around once a season for most riders. The second interval (~150 hrs) is closer to once a year, maybe every 2 years for lighter-mileage riders. (Instrcutors service ours 2 times a season, somtimes 3!)
Whether you're closer to the yearly or the every-2-year end of that range depends on how and how much you ride. If you're putting in serious hours, riding in dusty or wet conditions a lot, or you're a heavier or harder-charging rider, lean toward servicing more often. For most weekend riders, once a year keeps things running well. Skipping the 50-hour service isn't ideal, but it's a lot better than waiting too long and turning a simple service into an unplanned rebuild.
You can mitigate these repairs with some good monthly and weekly habit. Forks and shocks that are set up poorly wear faster. Check air pressure monthly; a shock or fork that is losing air has problems and needs to be checked. A check your rebound and compression settings weekly; the dials get bumped more than you'd think when cleaning your bike. Keeping things dialed means the equipment is working the way it was inteded and will last longer.
Another favorite tip (from our old friend Ross in Whistler) is to alwasy run a fender on your fork. This helps keep dirt and dust off the crown and wipers, which makes a noticeable difference in wear of the internal and external parts. (and it shows how cool you are.)
Pros of staying on top of it:
- Suspension stays smooth and consistent
- 50-hr service (oil change and clean) runs roughly $110
- 150-hr rebuild (new seals, o-rings & parts) runs $225 + $$ parts
- Regular service catches worn seals and bushings before expeneive stanchions or dampers get damaged ($$$ Fix)
Cons of skipping it or waiting too long:
- Performance sometimes degrades gradually, so it's easy to not notice how much you're losing If you don't ride that often
- Waiting past 150 hrs risks turning a rebuild into a bigger, more expensive repair or a replacement.
- Dirty and worn seals accelerate wear on stanchions, which aren't cheap to replace
For advice and service, your local shop is the place to start. A few shops do in-house service, but others will send it out to a service center for you. Your LBS will reassemble everything for you and get you back to speed. Budget 1.5 to 2 weeks turnaround. If you typically handle your own mechanical duties, you can send ti direct to Fox and Rock Shox and DVO service centres.
