7 reviews for Lightning Bolt-on Axle – Front 15 mm x 148 mm x M15 x 1.5 Thread

  1. Dennis (verified owner)

    Great solution at a great price point to weight ratio. Fitted up perfectly and have had zero issues.

  2. Rene Ortega (verified owner)

    It works great and looks so much cleaner than the RS Maxle.

  3. Tyler (verified owner)

    Exactly what I needed after my original Maxle snapped at the quick-release lever. So far so good!

  4. Tanner (verified owner)

    After fruitlessly looking for this part at a few local shops, I was finally pointed to RAP where the it took me a matter of seconds to find this piece. It arrived within a few days, bolted right on and has been a total confidence boost with the allen wrench tightening system so I don’t have to worry about busting another quick-release. Will probably replace my rear axel soon as well with RAP.

  5. Josh Howell (verified owner)

    Really please with how fast I got this axle. From order to ‘in my hands’ in about 48 hours. The axle looks beefier and more substantial than the Maxle that it’s replacing. Threaded right in smooth as butter and looks like a perfect fit. Thank you!

  6. Matt Cavanaugh (verified owner)

    Another great axle! Have used 1 for bike trailer and happy to ditch junk stocked quick release for this one. Easy and fast ordering.

  7. Daniel Johnston (verified owner)

    Worked quite well. Threads machined very nicely, threaded into the fork smoothly. Only issue I had was the head of the axle was too wide. I had to grind down about 1/8 inch from the circumference of the head of the axle in order for the axle to sit correctly.
