Truth. The Inside Line pod has also been very much on point lately, well done Spomer.

Tacky Chan's don't have the intermediate knob which is present on the tire he is on in the riding photo.

I feel like I'm reading a Seb Stott/Henry Quinney article get created before my eyes. Y'all've seen two basic principles gt raised here. Here are a couple visual aids I made to help show the relationships I see people using to help solve the OP's question. The stars show the particular contrast being made: a brake system near it's optimum temperature giving some level of performance greater than a brake noticeably below that optimum temp. The blue dots are just some ways we might fill in the relationship for other temps. Note that this is a relationship (as the posters...

I view it as disc size controlling for brake power/modulation AND thermal capacity, while disc thickness controls for thermal capacity only. It also seems to be pretty well settled that you need more thermal capacity on the rear per articles like this and in my own experience. With that in mind, I've settled on a 180mm 2.3mm rotor front with a 200mm 2.3mm rear on a 29er enduro bike using Hope T4V4. The hopes are pretty dang strong and wanted more modulation on the front.

Certainly not Martin Maes or Troy Brosnan level of rider here, and most likely not near @jeff.brines either, but here's what I have found in 26 years as a bike mechanic, 30+ years of riding offroad. If you're primarily riding in terrain that has short descents or very short braking zones, 180mm rotors are probably big enough. Larger rotors might take you too long to heat up enough to get the full power out of them. On the other hand, if like me you live in a mountainous area with 5-10+ minute descents being the norm, and weigh more than...

Not to sound like a dick but I hope most people ignore this. 1) Martin is one of one. You don't ride a bike like him and neither do I. 2) According to the telemetry data I've seen, most (good) riders do in fact use their brakes for ~85% of a descent. Even Neko just noted at the WC level guys are on their brakes 80% of a run. 3) The whole point of a brake is to take kinetic energy and turn it into thermal energy. The more "room" a system has with respect to heat management, the better...

There is a big difference between the surface slightly bluing on a carbon steel rotor (on a car) during bedding in and turning an entire rotor dark blue on a MTB. A similar bedded in look on a MTB rotor (let's call it light blue) is not cause for concern, similar to cars. Deep bluing could be. MTB rotors being...

Rotor bluing not cause for concern with quality rotors and is standard in motorsports. For automotive road racing, bluing the rotor when bedding in new brakes is when you know the bedding procedure is done properly. Rotors were always blue on all of my race bikes back when I roadraced motorcycles. Cheap rotors might have inconsistencies in the material so they might warp under such heat, hence the importance of quality rotors. It seems there is less expertise or interest in learning here. Instead those searching for comfirmation bias of their purchases.

Yep. It lets air move in and out the post easier from the bottom as you cycle it, decreasing pressure on the seal head. Works a peach. One of those instances where voiding your warranty makes it less likely you'll need to use it scenarios. Gotta wonder if OneUp incorporated better air flow into their V3 actuator. Better seals are never a bad thing, decreasing the loads the seals experience is a better thing.

One point regarding long term disability, if you are turning your rotors blue (especially deep blue/ purple) from heat you are affecting the heat treating of the rotor. This can make them wear faster and more likely to warp.

I would be inclined to size for power and brake performance you want (ie. diameter) and use the thickness to manage heat if necessary.

Refreshingly SMART, not strange. The last thing the industry needs right now is somebody making a product that already exists in overabundance just because they can. Why waste any time, effort, and resources on making a DJ frame when you can source it as part of the deal with Spesh and get paid for riding it instead. We should applaud Neko's focus on what's essential here and actually providing some value to the market (the DH bike, in other words), otherwise they'll just turn into the 1547th "by riders for riders" company churning out generic flat pedals and handlebars...
