11/12/2024 7:50pm First off, thank you! And that’s a solid question. You can FEA full frames and estimate deflections, but you’re making a lot of assumptions, and they start to stack on each other, so things can stray from reality quickly. And speed to reality is crucial. Using FEA is useful but only for very basic analysis and often you can guess what's going to happen: I made the chain stay bigger, it got stiffer. FEA is useful for validating a scenario where I wanted it exactly X amount stiffer and then you verify in the test lab. I’ve always wondered if...

11/11/2024 2:54pm I’m not a petrochemical engineer, but I’m assuming there’s a 0-100% range because the fluid is a mix of chemicals with different heat capacities and boiling points? If so, I’m not sure the 100% boiling temperature would matter. I think as soon as any significant percentage of the fluid boils, your brake is useless until it cools. (No idea what...

11/11/2024 1:57pm You could do a materials test pretty easily. You would soak a bunch of different brands seals in different fluids for an extended period. Then you’d measure for swelling and loss of tensile strength.

11/11/2024 1:11pm I think it does have the relevant info though. If I’m correctly looking at that, “Siedebeginn” is “start of boiling” which is 360c And they test per astm d2887. I don’t know why they say there’s a 60c range on it though.

11/11/2024 12:13pm Because their claimed performance is such an outlier, I’m slightly skeptical of the Bionol and Gold fluid claims. I haven’t been able to find any real information on them other than marketing material. I’d love to see an actual Technical Data Sheet for them. Past a certain point it doesn’t matter though. The ETFE liner in your brake hose will...

11/11/2024 9:45am Dot 5.1 has a slightly better minimum spec than dot 4, but once you get into high performance fluids it really doesn’t matter. For example, the minimum “wet” boiling point for dot 4 and 5.1 is 311 or 356 Fahrenheit respectively. Redline RF-600 dot 4 has a wet boiling point of 400f. Wilwood XR race dot 5.1 has a wet...

11/5/2024 10:38am The wheels are laced to DT 240 hubs though. I just checked and it’s $15,500 USD. That’s a bit more than the Yeti or Santa Cruz offerings but I don’t think any of them are offering the Live Valve suspension.

11/5/2024 8:06am I had the same symptoms as they did on mine, and I swore up and down that something was actually wrong with the brakes. No matter how many times I bled them, they would pump out on rapid lever pulls. I met a guy from a shop who swore they could fix them and I had to eat some humble...

11/4/2024 10:00am There is going to be very inefficient heat transfer between the pads and the heat sink compared to the shimano version with the them being integrated. You could increase the thermal transfer if you used some kind of thermal compound but I’m not sure how that would stand up to water/mud. It will do something but just not nearly as good as having the pad bonded to the heatsink.

11/4/2024 6:04am Id like to expand on the loam review issues... I took my perfectly working mavens and bled them as most would - I noticed if i unscrewed the bleeding edge to much(more than half a turn) it would suck air into the caliper.... I knew the fix but deliberately left them and rode... felt fine but now once i started down a trail the bite point was moving all over the show. Took my bleed kit with me in truck and ONLY bled the caliper via unscrewing between 1/4 & 1/2 of a turn, vacuum bled and repressure... closed system...

11/3/2024 7:21am You clearly haven’t ridden them. The only brake that might outperform them is the Maxima. Way more power than my Tech 4 V4s or the MT7s I had before.

11/2/2024 12:46pm The bike industry is full of things that scream poor design and manufacturing. It's far from a SRAM specific problem.

10/30/2024 7:01pm Can you elaborate on why this approach is incorrect? Isn’t that the way a consumer would set up their bike?

10/30/2024 7:04am I read your final chart as the Maven winning because I prefer a quicker first touch to full power feeling over the Magura design. I have yet to feel how my Mavens run as I’ve had warranty issues since first building my bike in June till after the bike park closed. What little riding I’ve done pushing up at some jumps with fully working brakes they’ve been great. I’d prefer a shorter throw to pad contact but once it hits I have a very nice and solid lever with minimal additional movement. The people complaining about the force required to...

10/21/2024 11:51am The contact adjuster essentially changes the starting position of the master cylinder. If you don’t wind it all the way out for your bleed, the system will be under-filled slightly. It wouldn’t be disastrous to bleed it without it wound out, but it will change the feel of the brake. If you have it dialed to where you like it...

10/21/2024 10:09am The contact adjuster is very important. The reach adjust doesn’t really matter.
