looks like lower pulley is on backwards...? LOL

Saw this on Pinkbike today Gamux has a new Downhill bike for the AON Racing Team in Lenzerheide.

Lahar vibes are strong with that one.
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.
"We heard you. We just didn't care"
Hasn't that been happening for ages?
Could be for his derailur in a can idea?
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.
DUDE!
Gamux has got my Lahar!
In a world where a lot of bike developers are focused on e bikes, count me in
B1 killer B or vario techno
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)
this was the first time i specifically recalled seeing a picture of it.
No issues with waterproofing in mechanical systems. Odd how mechanical is still more precise, faster, and cheaper than electric but everyone needs “new tech.”
Rusted solid shift / dropper cables/housings are a thing. Especially dropper ones drip-fed by toxic ass sweat.
Huge problem on those World Cup bikes that never get rebuilt
Technology is not a replacement for bike maintenance. You simply have to tear your bike down once a year if you're riding a good amount and make sure you touch everything. Too many mountain bikers are in the ride it until it breaks or there is a problem mindset.
Disagree. I do less maintenance on my electronic stuff than I ever did on mechanical. The stuff that does get maintained is present in both flavors (i.e. jockey wheel bearings). The time I spend annually removing batteries to put them on chargers & replacing them is measured in single digit minutes. I'm not saying that everyone SHOULD go wireless, I'm just saying the anti-battery crowd makes wireless systems out to be some overly complex thing when in reality they're not.
I haven't seen one (that is replaced st least once a year) in probably the last 20 years. 2005 was the first year I had a bike with full length cable outers and it was a game changer.
There’s TONS of issues with transmission 90/70. I see lots of posts on other media (Facebook Reddit pinkbike etc) about shift quality skipping. Getting stuck in gear etc. I’ve had the best luck with xo about 2 years and I haven’t touched it. Just replaced a chain and cassette when it wore out.
X01 Eagle is the bees knees. I ran the same chainring (gx aluminium), cassette (the old 10-50t),shifter and derailleur for 4 and a half seasons on my old bike with only a new X01 chain about every year. The derailleur is still being used on one of the bikes by a friend who bought it off of me. I ran the last chain for 2 seasons (and I started waxing the chain in the same time frame) and just recently gave it to another friend to use it some more as I only measured 0,35 % wear rate on it. Based on the stats the bike (and the drivetrain) did 350k vertical and over 10.000 km.
This has been my experience as well. Just stay on top of chain wear and you're golden. The drivetrain on this bike https://www.vitalmtb.com/community/ARonBurgundy,30923/setup,41567 is still in operation today and it was lightly used when I built the bike in 2020. I did retire the cranks out of caution as I wore through a few layers of carbon on the arms.
I mean, I'll go on record and say I much prefer wireless shifting and have been extremely happy with my Gx Transmission drivetrains. That being said, I really don't give a flying monkey's banana on what people run, and I really wish people would stop being so damn angry that wireless shifting exists.
I think people miss just how easy it is to swap wireless drivetrains around when you do have issues. When my Gx T-type did die, it was a quick 5 min job to swap to another one off another one of my bikes and keep going, and for someone who travels a lot for biking this is awesome. Not having to bring spare cable/housing, or wait for a bike shop to open that may or may not have a particular part I need is great. Yes, I could have done that with a mechanical drivetrain but it's so much more of a pain.
Also, my spare parts bin is filled with various shifters and derailleur parts from both Shimano and Sram that I've acquired through breaking crap. Through the last 4+ years I've been running some form of wireless across all the bikes I maintain, I've only had one failure that SRAM took care of super quickly. Cannot say the same about both Sram and Shimano's mechanical 12 speed stuff, which was all made of cheese and required constant upkeep.
Now, can we stop complaining about wireless shifting and get back to rumors!
Gotta love people who write an essay about wireless shifting who then tell everyone else to stop talking about wireless shifting.
“…can we stop complaining about wireless shifting”
There are other sites where you can whine and moan all you want. 😉
