The 3D printed version of the modded NASA 3D fabric worked, functionally, VERY WELL! 

Hopefully, with the right TPU (a good lucid 95 ShoreA seems the best) they should be crashworthy and enable skidding over the asphalt you normally never want to touch.

I have put them on EBAY.COM.

CHipSPK cyclist hip and shoulder protection kit

Shoulder and or Hip protector kit for road cyclists.

These 2 pads are 3D printed (FDM technology) in flexible TPU polyurethane and fit conveniently under your lycra jersey or bibs. They can protect your collarbones or your hips.

They are compatible with summer weather riding.

One size fits all.

The total weight is 100 grams (2 pads).

No other protectors are as light and transpire to the point of being compatible with summer road biking. For the fastest road riders, these protectors are aerodynamically compatible and do not slow you down in a significant way.

The 3D fabric structure (NASA Chainmail) provides the flexibility needed to be worn underneath the lycra garments. They usually stay in place without help. If you are riding with particularly loose jerseys or bibs, you might have to find a hack to keep them in place.

This protector focuses on the body's easy-to-protect but vulnerable parts: the collarbone and the hip. Those areas tend to come in contact with the tarmac frequently, especially for cyclists who ride alone. Those areas are not covered by muscles and generate a direct hit bone to the asphalt.

These pads have been designed to dampen the first hit, skid over the asphalt and reduce road rash.

These protectors are the latest and greatest evolution of a project that went through a crowdfunding campaign and is now expired. This was the introduction video of the crowdfunding campaign:

The previous prototypes went through a crash (mine!). The performance of the protectors in that crash is the reason why I have decided to carry ahead with this project.

I am convinced that the probability of getting a broken bone when crashing with a bicycle is proportional to the rider's age. Meaning: if you are 10 years old and crash, you have a 10% probability of getting hurt; If you are 60 years old, you have a 60% chance of getting hurt.

The crash is visible here:

NOTE 1: These 3D-printed protectors are now very close to what they should be. However, so far, nobody has crashed on these protectors. Therefore, if you crash while wearing these pads, don't hesitate to get in touch with me, share pictures of the damage, and I'll gladly send you another kit.

NOTE 2: The color of these pads is linked to the TPU wire that the 3D printer has available. The current wire was of this “ocean blue”. So these pads are ocean blue.

This one will be a long development.  It is about reducing the viscous aero friction.  Therefore advanced complex aero marginal gain.

The idea was to buy the https://nullwinds.com/ kit.  But the cost and the weight turned me off.

But than I had a JUGAADDD idea!  30 grams per pair.  Cost ?(100% recycled).

Estimated 1 kmh gain at 40 kmh.

That is it!  I have just started this crowdfunding campaign:

https://www.kickstarter.com/projects/1563327935/chipspk-hip-and-shoulder-protections-for-road-cycl

I have now two months to SPAM any road cyclist anywhere.

The idea is to start by #Eddy_Merckx  !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Another invention of my buddy Toshiya :  The FORKBOOSTER.

Basically a set of adapters that , as you can see, do something that should not do anything.  But they were telling me that they helped out with the handling of the bike, especially downhill.  I was skeptic, and I decided to test them doubtful.  Put them on my WORST handling bike (TVT92).   Surprise,  all of the sudden, downhill entering the turns was easier.  I had clearly a better handling and feeling of the bike ?????????????   Everybody else that tested them say the same. 

I have no clue why they works? Maybe a question of wheel vibration when braking ?  All in all the through axle of the disk brakes was the only solution that they found to take away the disk noise when braking.  And that was vibration.

I have crashed!

Those protectors are pretty darn good!  I will always use them.

I'll give a try with a crowd funding campaign,  just to see if there is a chance with the industry, but as far as I am concerned the 100g kit is the thing.
