ROBERT AXLE PROJECT LIGHTNING FRONT FOCUS RAT 12 X 100MM
The Robert Axle Project Lightning Front Focus RAT 12x100mm axle replaces the bulky, proprietary stock factory RAT system with a sleek, ultra-lightweight, and rock-solid traditionally threaded thru-axle solution.
The Robert Axle Project has designed the ultimate upgrade for Focus owners tired of dealing with the complex and often temperamental factory Rapid Axle Technology (RAT) system. While the original quarter-turn design offers fast removal on paper, it is notorious for causing subtle disc brake rub, developing irritating creaks under hard climbing efforts, and feeling overly fiddly to align correctly. This kit elegantly solves those frustrations by converting the setup into a reliable, standard threaded interface.
This premium kit includes both a precision-machined front thru-axle and a custom traditionally threaded replacement nut that slips directly into your Focus fork.By removing the oversized factory levers and handles, it creates a completely clean, aerodynamic silhouette that drastically lowers the risk of catching on trailside debris or rocks.Once installed, your front wheel locks firmly and squarely into place using a standard 6mm hex key, bringing greater clamping consistency and peace of mind to your front end.
CNC machined in the USA from aerospace-grade 7075 aluminium and finished with a rugged hard-anodised coating, this axle is internally bored to minimize weight without compromising structural integrity.It is engineered to exceptionally tight tolerances, ensuring it will not shake loose during rough gravel descents or intense road sprints. It stands as a simple, durable, and highly precise hardware upgrade that makes wheel maintenance significantly more straightforward.

Why This IS For You
✅ Eliminates Fork Flex & Creaks: Perfect for Focus riders experiencing front rotor rub or annoying front-end creaking when pushing hard out of the saddle.
✅ Lightweight Performance: Ideal for weight-conscious road, cyclocross, and gravel racers looking to shave unnecessary grams from their bike's front axle.
✅ Clean & Safe Cockpit: Excellent if you want a minimalist, low-profile front fork aesthetic that completely eliminates bulky protruding handles.
Why This May NOT Be For You
❌ Requires a Tool for Wheel Removal: Unlike the stock handle system, you must carry a standard 6mm hex key in your jersey pocket or saddlebag to remove the front wheel for punctures.
❌ Strictly Focus RAT Specific: This axle system is meticulously engineered to fit only front forks utilizing the 12x100mm Focus RAT standard; it is not a universal axle.
❌ No Trainer or Trailer Attachment: This Lightning version is built purely for streamlined outdoor performance; it is not designed to attach hitch-style trailers or resistance trainers.
BFC PRO TIP
When setting up your new Robert Axle Project conversion, take extra care to thoroughly clean the internal recess of your Focus fork arm before dropping in the new threaded replacement nut. Apply a light layer of high-quality bicycle grease to the axle shaft and threads before sliding it through your hub. Always use a calibrated torque wrench to tighten the axle to the recommended 12 N·m—this optimal, uniform clamping force is exactly what eliminates frustrating rotor rub and ensures a perfectly quiet ride!
