Anyone tried MTX brake pads? Guys at the local shop were raving about them. Made (designed I guess) by a local guy here in SLC who came from a moto background. I grabbed a pair and will try them out when my current shimano metal pads wear out.

Probably but nothing beats the first hand info from the sexperts on here

A buddy of mine knows the dude who started MTX and her swears by their pads. I bought into the hype and am now running reds front and back (he's 20 lbs lighter than me but rides a lot faster and is on the yellow ebike/Clydesdale version which has an even stronger bite).
The initial bite on the reds is lighter than what I'm used to on Shimano 4 pots + resin pads. It softened that Shimano on/off feeling and I now have some modulation which I'm really liking when riding steep stuff. In terms of raw power the reds feel a tiny bit stronger than the resins, especially when they get warmed up. I haven't had issues with fading on longer DHs, if anything the grab seems to increase (caveat: I've never had issues with fading, even resin pads on 180 rotors). Noise-wise I've had random and very rare squealing in the dry, more consistent when wet but that's not exactly uncommon. Durability is TBD but I've heard great things. No more rattling sounds from the fins is a significant benefit.
When I picked up the pads from the owner he told me they didn't need to be bedded in. I made him swear he was serious then went straight to Silver Fork to see if he was right. He was mostly right, they do need to get to temperature a bit. The first pull on the lever dropping into the off-camber section at the end of Lazy Prince had me concerned I was going to die a brakeless death"Your wife being mad is temporary, but pow turns do not get unmade" - mallwalker the wise

The Pro's Closet just buys bikes for cheap and flips them on ebay, you can do the same if you can upload some pictures and pack the bike for shipping. But if you want it gone right away it might be worth it to sell it to to TPC.

I broke a Shimano hg-x11 chain a second time in one week. Coincidence?
Wear was bellow 0.25 on the park tool indicator.
Bike had a pf30 gossamer, I switched to an ultegra crank. Is the chain line different between the two?
Chain was waxed. I put it though 5-6 ultrasonic cycles. Could that have damaged it?
I am a beast but I only weight 67kg. I have a chain on order since I broke it the first time, but should I look at anything else?

Even if chainline was different, I can't imagine that playing a huge part unless you're doing some serious sprinting fully cross-chained.
Pics of break? How did it break? During a shift? standing up?
Also: quicklink or pin? did it by chance break at the pin you installed it at?

I do a fair bit of cross chained riding. I seldomly use my smaller chainring. First time I broke it standing up crossing a street with a car coming. Ok maybe that's on me. Second time I was in the saddle, climbing, not during a shift. Pin just popped out.
I have SRAM master links. Both times it broke at some random pin not the master link.

My experience is limited, and involved some worn parts, but I think that'll work. Non-Shimano 12 speed chainrings (and chains?) are, according to Wolftooth, wider than Shimano. So, SRAM chain on Shimano should be fine, you just might not get the most out of their fancy shifting. I had some issues going the other way, running a Shimano chain on a non-Shimano chainring. Post up your results, regardless.
Remind me. We'll send him a red cap and a Speedo.

One of the pistons in my 4 piston XT 8120 brakes is stuck. I can push the other three in easily. Tried with the system open at the lever port to no avail. Pumping the lever, all 4 pistons will move in and retract back normally. I just can't push that one piston in any further. Any ideas?
Do I need to push the piston all the way out and clean it? Never done that and nervous of making it worse/breaking it. Bike is rideable now but with horrendous brake rub (piston doesn't retract enough to create room regardless of how caliper is adjusted). Got a 2 day ride with the wife for our anniversary this weekend and need to not fuck that up. Guess I could steal the front brake off my old bike in a pinch but would rather not. Brake is new this spring, maybe 50 rides or so, a few that were quite wet a muddy.

Running too short of a chain cause them to snap randomly/often?

Wouldn't it would be most likely to bend the der hanger inwards ?
A buddy had a Rocky hardtail about 20 yars ago that would bend without hitting anything,
it would seem the rear dropouts didnt have enough meat and the der material was a bit wimpy
I can't see an ultra sonic cleaner doing anything to a chainLee Lau - xxx-er is the laziest Asian canuck I know

My guess would be some ham handed shifting at some point. A rough shift can tweak the chain just slightly and begin to unseat the pin from the plate. It'll continue to worsen over time with more (regular) shifting and torque, and eventually fail.
Pretty much every modern chain I've seen fail was due to that or an impact.

Option #2. Bin the Shimano brakes and get Maguras. Sram pistons suck also but not as badly as Shimano.

Ultrasonic cleaner had some diluted simple green.
Chain was definately on the long side. This is on my road bike, so no suspension travel.
I used KMC X10.93 for years commuting with little maintenance. Any reason not to get the x11.93? Are the Shimano higher end chains more durable?
