1) Grip tape is not allowed on the extensions, even in the point where the hands contact the extensions?

Grip tape or rubber is allowed, but only where the hands will be positioned. (Handlebar + extension) (nothing have been updated in the rule regarding this point. Where did you find that?)



2) A rubber grip is not permitted on the extensions, where the hands contact the end of the extensions?

See above
Grip tape is fine. Another great example then of Aussie officials on a power trip. And I wish that were me being overly dramatic but it's regrettably the case.

Nice!
What is that chainring?
And can you remove the front derailleur hanger?

Thanks!
It is a 56 110bcd chainring of AliExpress. The front derailleur hanger is removable however I do not have the right screwdriver at the moment. But will do.

It´s not a NW chainring. Do you think it won´t drop the chain?

Not really. The chain is pretty tight and I have already tried it on some bumpy roads.
The roads in Holland are usually smooth.

Ok.
Its just I have dropped chain on my roadbike while using NW chainring and Shimano non-clutch rear der. Coasting thru bothhole when chain is on the 11 or 12 sprocket.
Chainring was oval though.

Why the XTR 12 speed chain on your 11 speed setup?

I wanted bigger pulleys from Kogel bearings but could not get them here, then I started to think why not XTR pulleys and followed by the chain.
The chain is a lot more silent on the steel rotor Uno cassette, I think because of the longer inner plate witch grips the cassette teeth better.
So far no problem and shifting is really good.
Shimano says that the 12 speed chain can vibrate on some chainrings!

Gotta admit, it's a cool looking bike. The downtube is an interesting shape.

dropped a chain in the first race and finished 6th, then followed it with two 3rd place finishes.

Here is my Trek Speed Concept 7.8. Year 2012-13 or something.
Bought second hand and thought I won´t change/upgrade a thing :D but could not resist of course.
Disc wheel is 10sp PRO with 11sp machined cassette. Can´t use the largest cog, because der hits the wheel. So I adjusted the low limit screw and can use 10 cogs.

Have you tried Rotor Uno cassette? It worked for my 10 speed Dt Swiss disk wheel.

No I haven´t. It doesn´t really bother me. Hope I won´t need this low gear in any race.
