Ultra Axle Installation
Some of our frames include aluminum Ultra Axles. These high performance axles provide about 40 grams of weight savings per skate compared to steel axles. Some frame sets will include Titanium Gray axles and others will include Cyberpunk Pink axles. Refer to the product pages for colorway details.
Special attention must be paid when installing these axles. Aluminum axles tend to be self-locking when used in aluminum frames due to a phenomenon called galling. High friction develops between the two parts which keep the axles from backing out during skating. However, the downside is that if they are over-tightened, they can get stuck. Please read the following instructions carefully.
Axle Installation
- Prior to wheel installation it's good to verify that all axles can be fully threaded by hand into each threaded hole in the frames. If the axles gets stuck when threading by hand, stop and inspect the threads for damage or burrs. Never use a tool to force an axle. Each axle should smoothly thread in by hand without tools. By forcing the axle you risk damaging the threads. Please contact us if you notice any issues.
- Slide the wheel into the frame channel.
- Align the bearings, spacer, and frame hole using a skate tool or a wooden pencil (see video). We recommend the Sonic Sports skate tool, which has a bearing alignment feature. When all these features are aligned, it will make inserting the axles much easier.
- By hand, carefully start threading the axle into the frame.
- Use a skate tool to continue installing the axle. Turn lightly until the axle stops spinning freely. Once it stops turning easily, snug the axle no more than an extra 1/8th turn (see video on our Instagram and YouTube channel). Do not over-tighten. This could result in the axle getting stuck. Stripped or stuck axles are not be covered by product warranty.
- Do not use power tools to tighten the Axle Screws. Repeat for each wheel and axle.
Note: when removing axles it's not uncommon to hear a "screech" or "pop" sound as you overcome the friction in the threaded joint.
Very important: Never apply Loctite on the threads of axles. Since Loctite is a liquid it can get all over the axle shaft and bond the axle to the bearing, which is very bad.
