SKU: LIG519.C Category:

Description

  • This axle is designed to replace your front Cervelo R.A.T. axle and includes a threaded nut, which the axle threads into.
  • 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 or create wind drag. Aerodynamic design.
  • Light Weight. Our axles are internally bored to remove unnecessary material without compromising strength.
  • 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.

This is NOT an axle for attaching trailers or trainers.

 

Specification

  • The diameter of this axle is 12 mm and the true length of the axle shaft is  130 mm. Please note: Thru-axle lengths do not equal hub standards. An axle has to be longer than the hub to fit in the frame. A 12×100 hub does not equal a 100 mm long axle. This axle has been specifically designed to work with our fork insert and will not measure the same length as your stock RAT axle.
  • Weight: Axle = 30 grams Nut = 5 grams
  • The axle is precision CNC machined in the USA from 7075 aluminum and hard anodized for rugged durability. Our axles are built to the tightest standards in the industry.
  • No special tools required. Design allows for installation or wheel removal using your standard 6mm hex wrench.
  • Designed, built and quality tested in the USA. Proven around the world.

    Amazing stuff. Saved 60grams from my R5 Disc stock RAT axles (front + rear) with these – nobody else really offers an alternative on the market. Top shelf product + the communication and shipping overseas was super quick as well. Highly recommended.

  2. Rob Green (verified owner)

    This kit is outstanding! Swapped out the R.A.T axles on both mine and my wife’s Cervelo S5’s and they are stiffer with this proper bolt thru. The aweful R.A.T axle system is over engineered and totally unnecessary, this kit puts the bike right and the way it should have been from the factory. Congratulations on such a well thought out and beautifully engineered upgrade. I received this, all the way from the USA, in 4 Days, those 4 days happened to be the Easter holiday weekend! Amazing fast delivery!!
    Many Thanks!

    Perfect, easy installation. Great product

  5. Christoph (verified owner)

    Weight saving was the the idea. It worked out perfect, but still the RAT system does the release job much quicker..
    However I assume we all buy it for the esthetics and to save weight.

  6. Boris Vinitskyi (verified owner)

    exactly what I need! Fits perfectly to my bike cervelo s5 gen III

    The RAT axle on my 2018 Cervelo R3 was a bit sticky so I sought a solution. This bolt on axle fit the bill. Easy install and topnotch fit and finish. I also liked the looks of it better, so I decided to replace the rear RAT as well. Saved a little weight even after factoring in the hex key. Nice!!

  8. Sam Bounds (verified owner)

    Had a Couple of problems with Front Rat on 2019 R3 Cervelo with 454 Zipp Front wheel.
    1. Front Disc brake would rub no mater what adjustments I did, the rub would return, especially when climbing out of the seat.
    2. On technical 80 km/hr plus descents the feel on front wheel was a little vague in the apex of the comer.
    Installed thru axle, all problems gone. I have a solid front wheel which I can throw into a corner at speed.
    Front end is now stiff and the brake does not rub when I’m out of the saddle climbing steep hills.

    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!

  10. Sean D (verified owner)

    Works a treat. It is far more reassuring than the previous RAT but will require I carry around the right tool to be reassured I can remove the wheel if I have to deal with a flat on the road. Perhaps a lever on the non-threaded end to help unscrew the axle would be useful.

    Ordered a set of thru axles for my Cervelo S3 disc last sunday, delivery in Germany was today (Friday five days later) – awesome!! Only a single axle was in stock at several dealers, so I decided to buy the complete set directly in the U.S. As a hobby rider I have time enough to grab an allen key to remove a wheel in case of a puncture or bike maintenance, so the screwed in axles giving more stability and saving weight are perfect for me!

  12. Victor (verified owner)

    So in short I would say if you decide to buy a R.A.T equipped Cervelo, you might as well ask them to keep their really pointless over engineered axles and get both the front and rear replacements axles from The Robert Axle project.

    I hit a pot hole with my front wheel and the front RAT axles on my cervelo s5 broke (the mechanism on the inside of the axle got damaged) and couldn’t turn any more to have the axle come out, so the wheel was stuck, had to take it in to a store so they could manually get it out.

    Also most importantly as a 88kg rider with a good sprint, I never felt confident as my front wheel always felt like it just wasn’t stiff enough, I taught the envy wheels/frame was even bad at some point but NO it was the front axle, the moving parts on the RAT axles makes the wheel or the front area very very unstiff especially on steep descends for a heavy rider, I always felt like my wheel was about to wobble and could never go as fast as I could.

    long story short I replace both axles and I could push the bike past the speed mark I used to feel like I was about to wobble. bike is feeling much stiffer at the front. As a plus it looks better too.

    Going to keep pushing my speed limit slowly but surely with these axles and aim to get closer to 90-95km/h…I had not experience this on my previous bike but yeah…

    I bought two axles for the wheels. I have a Cervelo R3 Di2 disc bike 2019 with RAT axles. Fast shipping and communication. I recommend Robert Axle Project to everyone. God bless US

  14. Dario D’Onofrio (verified owner)

    Swapped my cervelo RAT and extremely happy with that. Extremely happy with that, way better than the original one.

  15. Will (verified owner)

    This is the perfect replacement for the stock r.a.t. axle on my Cervelo S5. I got a flat while riding and in the process of removing the cervelo axle, the head of it snapped right off in my hand. Needless to say that was the end of my ride. My friend John told me about this axle so I gave it a try. Never using anything else on my S5. Simple, easy to install, and adds a clean smooth look to the wheels. Maybe cervelo can take a cue from your company and make better r.a.t. axles.
