Description
- This axle is designed specifically to replace a rear R.A.T. axle on a Cervelo bike with included derailleur hanger.
- Lightning is Better. Our front and rear Lightning Bolt-On axles offer a stronger, more durable, lower profile and lighter weight option to replace your stock thru-axles.
- Low Profile. No more bulky handles to strike trail obstacles. Aerodynamic design.
- Light Weight. Our axles are internally bored to remove unnecessary material without compromising strength. Our axle weighs 36 grams. Our axle and hanger weigh a combined 54 grams. Front and rear, our axle system saves a combined 58 grams.
- Easy to install. Our matching front and rear Lightning Bolt-On Axles only require a standard 6 mm hex wrench for easy installation and removal.
- Better Tolerances. Manufactured in the USA to the tightest tolerances using aerospace materials and CNC manufacturing. No longer will your axle loosen while riding.
- Available Security. Learn about compatibility with Hexlox bike security systems.
This is NOT an axle for attaching trailers or trainers.

Fit my 2018 Cervelo R3 perfectly. The install was easy, fit and finish top notch. I didn’t even have to adjust the derailleur. If you want to get rid of the RAT lever this is the way to go.

After getting my new cervelo I was having issues with a noise in the rear of the bike. Came to figure out under power the rat axle wasn’t secure enough. So after some looking I ordered front and rear axle replacement. Installed took about 15 mins with good directions and tools needed. Now everything this how it’s should be quite and looks good

Amazing axles. I didn’t need to replace my RAT axles but when trying to find a RAT rear mech hanger in the uk it was proving difficult with only 3 distributors available. This got me looking in to conversions, and I am glad it did. Gone with the lever for neatness, looks better, lighter, and more secure if leaving outside a coffee shop. So glad I bought these as the quality is great. Communication via email was prompt, informative and lighthearted too which was nice. Good work

Replaced the front and rear RAT axles on a Cervelo R3. Love the precisely machined threads, it gives a very confidence-inspiring, secure fit. Feels super solid on the bike, and no more wiggle room when installing the wheel. Makes it easy to align the brake rotors when a wheel is removed and replaced. Lighter weight and cleaner appearance is a nice bonus as well. Love these axles!

Replaced my Rat Axles on my 2019 Cervelo R3. Bike feels different, but can’t place what the difference is. Is it lighter? Is it stiffer? Is it both? Logically, for sure lighter, but can’t really tell by lifting it. The way it rides just feels better. If I end up getting at Aspero, these will be ordered the day I order the bike!

As for the front axle, it feels far more solid (and hence safe and secure) than the RAT it replaces. However, it does require a suitable wrench to remove if I have a flat out on the road. Perhaps a lever to help get it loosened on the non-threaded end would be a help?

The material is awesome and looks really great. Also the fit was really good and it arrived in 1 week from USA to Canary Islands so that was a plus.
Only thing: i didn’t find a video where it explained how to change it so i think that is the missing bit to make a 10/10 product.

Great upgrade for my 2020 Cervelo S3 where they used the R.A.T system that must have been designed by a moron. I mean it’s a bolt and a nut. How complicated, flimsy and unreliable can you make it?
I’m really happy with my Robert axles. A design that has withstand the test of time; a bolt and nut.

Been struggling with creaks and disc brakes not aligning properly on my 2018 Cervelo R3. Thought it was the BB, the hub, rotors out of alignment. Finally realized it was the Cervelo R.A.T. Thru Axles. Replaced both the front and back with RAP Lightning bolt-on thru axles. Bike runs great and looks better. Installation instructions were spot on. I highly recommend this product.
