My Bike Rack

Your whole quiver, one rack.

Add each bike once with its fork, shock and rider. Pick XC, Trail, Enduro, Bike Park or Downhill and both ends re-tune on the spot.

  • Your bike, drawn your way. Full suspension or hardtail, 12 frame colours, and an air or coil shock to match the one you run.
  • Riding conditions. Rocky or flowy, wet or dry, temperature, pack weight and a firm or plush feel. Pro
  • Pre-ride check. Pressures, sag, axles, bolts and brakes in about 60 seconds.

The maker's numbers. One glance.

Every result says where it came from: Manufacturer chart, Partly manufacturer or Estimate, with a link to the maker's guide.

  • Pressure dial with the pump number indoors and the number at a cold trailhead.
  • Sag check in % and mm against the maker's range, with an O-ring guide.
  • Sag helper and troubleshooter. A guided O-ring check with a countdown, and fixes for harsh, bottoming or kicking, worked out from your own clicks. Pro

Step by step

Every click, spelled out.

Drag the precision sliders to match your fork or shock, or follow the same setup in plain words. No chart reading.

  • "Turn the red knob clockwise until it stops, then count 6 clicks back out." Instructions follow the clicks you set.
  • Volume spacers with where the top cap is and when to let the air out.
  • Save to History what you actually ran, with a note for next time. Pro

  • Hardtails show only the fork, with no shock setup to wade through.
  • Share or print a setup card for the workshop or a customer. Pro
  • Home-screen widget with today's pump numbers. Pro

FAQ

Before you pump.

Which forks and shocks are supported?

65 popular models from 12 brands, including Fox, RockShox, Marzocchi, Öhlins, DVO, Cane Creek, Manitou, SR Suntour, Formula, EXT, X-Fusion and PUSH. Missing yours? Email with the brand and model.

Where do the numbers come from?

From each maker's published setup chart wherever one exists. Where a maker doesn't publish a value, the app calculates an estimate and labels it, so you always know which numbers are which.

Is it a replacement for my manual?

No. The settings are starting points. Always check your product's manual and never exceed the maximum pressure printed on your fork or shock.

Does it work without signal?

Yes. Everything is calculated on the device, so it works at the trailhead with no connection.

What about my data?

No account, no ads, no tracking. Your bikes and history stay on your device.

Does it run on iPad?

Yes, on iPhone and iPad with iOS 17 or later. On iPad it works well as a shop reference.
