How to choose your MTB front wheel axle

The front thru axle screws into the fork leg. Its reference therefore depends on the fork, and not the wheel: this is the most common source of error for this part.

The dimensions to measure

  • Diameter : 15 mm on almost all MTBs, 20 mm for downhill and dual crown forks.
  • Width : 100 mm for the classic standard, 110 mm Boost on recent MTBs.
  • Total length and thread length : they vary from one fork to another, even with identical diameter and width.
  • Thread pitch, which varies between brands and generations.

Pay attention to fork generations

The RockShox Maxle Lite, Stealth and Ultimate are not interchangeable between generations, and some are specific to a fork model (SID, Reba, Pike, Lyrik). Fox, Öhlins, Manitou and DVO each have their own lengths. Burgtec offers axles tailored by fork model, which eliminates ambiguity when the original axle is missing.

Lever or Allen key?

  • Lever : tool-free removal, convenient for loading the bike or trailside repairs.
  • Allen key : lighter, more discreet, and nothing protruding to catch on branches.
  • DT Swiss RWS : repositionable lever that tightens like a bolt and then folds against the fork — the compromise between the two.

Classic quick release

On older MTBs, the front wheel is secured with a 9x100 mm quick release. Check your fork spacing before ordering: you cannot switch from a quick release to a thru axle without changing the fork.
