You've planned a few days in an alpine resort to enjoy the bike park. With your lift pass in your pocket and your bike loaded in the boot, the season is here. But between the continuous runs made possible by the gondolas and the nature of the terrain, the reality of the bike park is radically different from trail mountain biking. For your suspension, it changes everything.
In a bike park, you rack up hours at a speed that trail riding just doesn't allow
This is the fundamental difference between the bike park and traditional trail riding: ski lifts eliminate the climbs.
On a traditional trail running route, a 3-hour outing includes just as many ascents as descents. Your suspension is only working actively for half the time.
In a bike park, you ride downhill continuously and head back up aboard a gondola or chairlift. Result: an active rider can string together 8 to 12 runs per day in a bike park. On a 10 to 15-minute track, this represents around 90 minutes to 3 hours of pure descending.
Over a week of bike park riding in Méribel, Avoriaz, La Clusaz or Valloire, you can easily rack up 15 to 20 hours of actual descending, the equivalent of several weeks of trail riding for a weekend rider.
More intense impacts, at a higher frequency
It is not just a question of volume. Bike park terrain is designed for pure descent: jumps, drops, technical zones, rock gardens and roots are concentrated on dedicated trails.
Unlike trail running, where technical sections alternate with runnable parts, a downhill mountain bike track delivers impacts almost continuously from start to finish.
Every jump and landing generates a force transmitted directly to the fork and shock absorber.
At high frequency, the hydraulic oil heats up more quickly, wiper seals accumulate impurities faster and guide bushings undergo repeated lateral stress with each impact. Specialists agree on this point: bike park and downhill riding is one of the most severe conditions for a mountain bike suspension
What this means in practice for the interview
Fox and RockShox recommend shortening service intervals for bike park and downhill riding.
Where a trail rider can space out their full service up to 125 hours or once a year, a regular bike park rider should aim for at least one full service at the beginning and the end of the season for regular summer riding.
The signs of a tired suspension are all the more quickly noticed in a bike park: a fork that lacks progressiveness on landings, an unpredictable rebound upon landing a jump, a loss of sensitivity on technical sections.
On challenging terrain where speeds are high, these symptoms are uncomfortable and directly affect bike control.
Before heading up to the ski resort, check the condition of your suspension
Before heading off for a week of bike park riding in the Alps, it’s a good time to check the condition of your suspension.
A thorough service beforehand ensures your suspension is at its best so you can make the most of the trails. Discovering worn suspension midway through a trip means a ruined week or tackling a track with equipment operating below its capabilities.
Riders who wish to entrust their mountain bike suspension service to a specialist workshop can opt for a mail-order service: dispatch of the removed fork or shock absorber, overhaul within 48 hours and home delivery. A practical solution for preparing for the season.
One final point for those who hire their bike from a station
Many riders arriving at a bike park rent their bike directly at the resort. It is a good option for trying out the discipline without investing in a downhill mountain bike.
Alpine resorts such as Avoriaz, Les 3 Vallées or Tignes/Val d’Isère offer full-suspension bike hire starting from 35 to 55 euros a day.
However, if you bring your own bike, trail or enduro, keep in mind that your fork is not designed for the same stresses as a DH bike.
A travel of 140-160 mm remains suitable for blue and red bike park trails, but the frequency of descents requires more rigorous maintenance monitoring than in standard trail riding. Plan for a full service at the end of the season.
