I thought GX battery placement was a problem in wet conditions?

Having killed a GX T type this summer already I'd say:
 

I hope they invested in some better waterproofing....

Hayes Dominions are on the market for a while now nd after trying some other brakes they are the one I keep coming back to. I wonder if anyone heard anything about Hayes jumping on the Mineral Oil trend as well? Or maybe a new version with minor updates like tool free bitepoint adjustment…

haven't heard anything, but it wouldn't surprise me if they eventually made the switch.  I guess the concern would be compatibility between models, or rather incompatibility.  i'd guess they'd probably launch a next gen dominion / dominion 2 to avoid having parts from each model being mixed up (seals, pistons, etc) but carry over the design features that make it such a good brake.

Most likely just the S1000 with a XXSL Carbon Cage and Clutch

Nino doesn't ride no S1000! 🤣 But to be serious. The Transmission derailleurs' design language has changed since GX. The entire XPLR line of derailleurs has the same battery orientation. So this looks like the direction they're going moving forward. 

Blackbox already after only what... two years. An update/revision release after barely three years?

there's also DT and orbea articles on homepage too.

What pedals is Martin Maes running? Looks like a mallet but not a mallet?

I heard they're jumping to mineral oil. Been contemplating scooping up a few sets of the current model.

Speaking of seeing things on the other site, it also showed that goldstone has qualifying / race only wheels with unsealed hub bearings.

Pretty sure it's a device that bolts in place of a blown motor on an e-bike, that makes it just a bike with a BB.

Yes it has, along with oil instead of grease in bearings. Race/Qualifying runs only I would assume.

I believe Steve Peat did that. The bearings would last a run as the oil leaked out on the way down.

In a world where a lot of bike developers are focused on e bikes, count me in

A puddle of oil in the BB shell to lubricate the BB bearings instead of grease. 

Though if you run oil in the shell, it makes sense to run outer rubber bearings to keep some of the oil in and not just flow out (bearings aren't really restrictive for oil) and not splash all over the rotor.

Trying out bearings by hand, at very low speeds, it's the seals that appear the most draggy though. So a small amount of grease and some zz covers should do the trick.

I think I recall them using an electric drill to break in the bearings too...

Guess the DB8 is over. 

The Hayes using DOT has been one of the things holding me back from swapping to them. (lifelong Shimano/TRP guy) My dog is a weirdo and licks the floor and while I do my best to clean up I'd rather him accidentally come in contact with mineral oil than DOT. (yes I know both are not good)
