Here we go again. 🥳 (Throwback to page 851).

I was already quite surprised that we didn't get some shots of this stuff when the YT b-team raced it at Poland two weeks ago.

FWIW somewhat answering my question from before - I emailed Egerie about getting a bike made and they only do face to face delivery, they do not ship. 

Still very cool to admire some of his work and Paul's bikes, though!

This is funny it doesn’t deserve downvotes

There is a lot going on on this handlebar.

Is Morgane Charre running her front Neo sensor on the handlebar instead of the brake caliper? That cable doesn't appear to be waiting to be reattached to the fork. Interesting way to potentially run a sensor.

That's the handlebar remote (see the cable going to the ring controller on the bar). Allows the rider to switch between the preconfigured shock tunes. It's shown in the app / manual, but I've never seen it for sale.

The "sensor" you're referring to is the battery and transmitter.

ahhh, the handlebar remote that wasn't available at release. Never saw a pic of one so it was a bit puzzling.

Not sure if it's been discussed in the bike industry or internets too much, but I'm kind of into this:

Looks like Magura has a new MDR-P rotor 🧐

Let’s hope with higher quality rivets as well

what's on henry kerr's gamux (from Q2 loudenvielle after he crashed...thankfully he's ok b/c w/ his OTB crash, it'd be easy to say "ejector seat?" external resevoir for rear brake? ABS type thing?

Could be a water reservoir to drip onto the rear brake and cool it, this is something I've seen used from time to time by racers over the years. Sounds like the track is hard on brakes, so some cooling might be beneficial. 

What a contrast from last week when people were having issues with cold brakes.

Back in the 90’s many riders (including Warner IIRC) experimented with water dripping from a bottle onto the rear disc to prevent them heating up. Could it be that Kerr rides a bit ‘draggy’ on the rear brake which, especially on the steep lower sections at Loudenvielle, could have been giving him issues?



Edit- Finkill beat me to it.

Definitely a dripper. 

Surprised they didn't go to 223mm rotors first? Bigger rotors drop temps quite a bit

thanks all on the dripper thing. had no idea!

so does the back brake really heat up that much? i'd think the front is where the real heat is (maybe there's a dripper there and we can't see it).

I would think the rear would heat up more than the front because of how you use them. Front brake hard and intermittent and rear brake is more constant for speed management, thus not allowing it to cool. 

I’m surprised it gets that hot in 3 minutes but I guess it's super high intensity.

Yeah rear brakes can get absolutely cooked on a track like this, as even the pros will brake drag half the run. Because the corner speed at some points is quite slow after the shutes, they just need to get rid of that energy through the brakes. Front brakes you can't drag going down the steeps, as you'll just lose traction and miss the lines. 

You can check on your bike if your overheating due to the disc discoloration. 

It's why some pros go up and down rotor sizes/pad compounds to get the brakes at optimal temp, here overheating is an issue, for other tracks maintaining heat is an issue.

And for this reason why Troy often runs a 220mm rotor in the rear but a normal 200mm up front.  Rear brake is consistently "on" far more than the front.

Phil Atwill mentioned something similar on his sleeper podcast about a syringe that dripped water to his rear brake

They did mention it on the official broadcast that some teams were using a "dripper system" to help with rear brake temperature, so you guys were indeed correct!

Loic was running a larger rear rotor this weekend as well.

A lot of the quicker kids in Whistler been doing this for a few seasons. Haven't fully understood their explanations but I'm not exactly keeping up with them either 😁

The rear brake normally does at least as much work, if not quite a lot more than the front. Not many people are truly 50/50 if you look at something like brakeace data, so its normal for the rear to get hotter. You can often see its more common for rear rotors to be discoloured more than the front too

I feel that the larger rotor in the rear balances out the “bite”and makes it stronger.  If I run the 220 in front it find the initial bite pitches my fork too much and upsets the bike balance. The first rider I saw do this was Troy Brosnan

I seem to remember Martin Maes doing this a few years ago too?

I first encountered the idea in Enduro-MTB's (fairly persuasive) article about it.
