Dot fluid.... watch all the shimano fanboys say how good dot is all of a sudden.

also, why are we still having to strap levers to bars to get a good purge and solid feel.....
I've done it with shimano brakes for ages as it makes them feel even better, downside is you've gotten do it often to keep them feeling good.

I like shimano brakes a lot more than sram (I’ve yet to try the mavens tho) but you have to admit dot is objectively better than mineral oil.

I knew id get downvoted by Shimano users, happens everytime... cant even joke about their products.

Of course it's mineral but Far out come on boys/girls haha.

No, your comment has been said a million times before and you were clearly just trying to stir.

Something on AP upper fork. Could be another version of a mass damper?

I also noticed his rocker link has a flip chip at the top shock mount. He’s back on the steel chainstay as well, which is switched from all the photos early this week. Lots going on with this machine!

There is only one AP and that is Aaron Plessinger. 🤣 When you rock a cowboy hat and mullet like that dude does, you get to own the nickname across all two wheeled sports.

I want to know more about those single wall ENVE rims! 

They might not be single wall, just slim, but they sure look like it.

Same here. I think they are the same ones frameworks is running. Says on enves site dark 9s

Plessinger isn't on Pierron's level though, so no. Once you're a threat to win any race/championship you enter THEN you can talk about official nicknames and permanent racing numbers ect.

Moto AP is awesome, but he's not on RC, or RV, or TP's level yet.

I recently bought 2 used RockShox Kage R coil shocks and one of them had a wierd/different name engraved. Could this be some kind of special shimmed shock? Has someone seen this?

Its kinda old/long ago but still interesting.

About enve wheels, I’ve seen the dark 9 carbon ones and they’re low profile, for sure not single wall, look ready to be out in the wild, I’ve been told that they’re figuring out the finish with the new molds that seems not perfect but that’s just a visual thing.

And from the other site something interesting, alloy rims from Enve, I didn’t knew it would’ve been a think like ever

From the looks of it, it pretty much looks like a flow EX3 rim. I might be wrong but it wouldn't be surprising that they would run other brand's rim for testing/performance purposes (didn't they ran crankbrother wheels before they came up with enve's prototype ?)

dak in action. let's take in all the bike-calming parts on this bike. pic by Jack Rice

sprung mass dealie, e13 sidekick hub and STFU. and that's just what we can see. considering 2nd thru 11th place were separated by just 2 seconds in qualifying yesterday, i'd be all about zen'ing the crap out of my bike too! his hair has to damp the movement of his head too, so double win.

Who’s gonna be the hero to make a mass damper with only parts from Home Depot?


I’m thinking PVC pipe and caps, springs from the random hardware section and maybe a stack of nuts on a piece of all thread for the weight. Bushings smaller pvc pipe?  

Edit- springs could be bungee cords too. That would be ideal. Nice and progressive

Somewhere, the engineer who came up with the Bontrager Bzzzkill dampers is gloating.

Bumping this old post as it seems the Wheeltop MTB drive train is getting more refined and looks to have a dedicated MTB option. Noticed when the Zuckerberg algorithm decided to feed me this today. 

I personally don’t care for or want electronic shifting, but I’m always excited to see competition in the drivetrain space

Pretty sure I saw a silver one sticking off the left side of a Fox fork with the number plate carved out around it. If someone posted it and I'm late to the game...apologies.

It was stupid obvious of course. But I'm not Lawnmower Man...yet.
Yeah...so what is this thing?

A cobbled together Home Depot shake weight might give some pleasant placebo effect, but I suspect that’s about it. They’re formally called Tuned Mass Dampers because the mass, spring rate, and damping coefficient are tuned to the application, with knowledge of the system mass and the spectrum of vibration input/output, to reduce the amplitude of system resonances. 

DH/park riding is absolutely a valid use case for a TMD. I’m honestly considering if I want to invest in some accelerometers and data acquisition and take a stab at designing a commercial product, but I imagine I would be late to the party anyway considering how many of these things we’re suddenly seeing around the DH circuit circa now, and I am pretty sure the actual market for these would be small unless sales were driven by a marketing engine as powerful as SRAM’s.

They might not be single wall, just slim, but they sure look like it. 

The profile looks very similar to the Crankbrothers Synthesis carbon wheels which was the original low profile carbon wheel, and they were co-designed by Jason Schiers (Enve founder) and Mello Bouwmeester (single wall carbon rim designer). Jason was working with a design consulting firm SR56 up until recently, so I wonder if he had any input/involvement in the new lower profile design, and maybe even an agreement with crankbrothers that no one else could use that design for 5 years?
