I think we understand this to mean different things. Each to their own, I will have my unpopular opinion and you can have yours 
Wouldn’t call mine unpopular given all the coaches you will find nodding in agreement.

I never said that I had 40mm of spacers. My comment was in response to a comment about someone else who was being made fun of because they had 40mm of spacers. And flexibility is only partially trainable. For example, I am almost 64 and have some arthritis of the lower lumbar vertebrae. All, the stretching in the world won’t make that better. I am simply less flexible than I used to be. I do agree with the sentiment that riders ought to buy a frame sized to them and their flexibility. Many (most?) people that I see out riding are on a bike with too much drop so they end up with an odd fit. This is made worse by the fact that most higher end bikes are not offered in models with a geometry designed to fit average people. Thek used to do this but discontinued it.
Great article summing a lot up in one place. Thanks for sharing.

I think that in a more or less steady state, TSS works pretty well. If you do more of the same kinds of things you typically do, more endurance pace riding in addition to your intervals, more time in sweet spot, etc., it should pretty accurately reflect the change in training load.
Thinking about some of the objections raised to TSS…technical MTB descent vs coming straight down a bike path, riding in the heat, the 5th hour being harder than the first, wouldn’t hrTSS account for those factory fairly well?
Cubic litre? That hurts my head.

so much easier on the brain if we use cubits 
Then we can argue about whose forearm, and arm wrestle for it!

I do ALL of the maintenance and repair on my (3) bikes. Nothing has tested my resolve to be self sufficient more than disc brakes.

Not even dropper posts? Must be a roadie
Other than proprietary suspension stuff, I’m stubbornly self sufficient as well. But a recent encounter with a DT swiss threaded retaining ring almost pushed me over the edge.
What seemed like a 1 minute job (based on youtube videos) turned into a multi-hour battle that had me thinking about taking the wheel/hub to the shop. I ultimately won the war, but it took an industrial impact wrench, a mig welder, fabricating a special tool, heat gun, and lots of swearing. The most impossibly frozen fastener I’ve ever dealt with, none of the approaches on the web/youtube would budge it.

Hydraulic disc brakes. And internal routing…
After several freak-out moments caused by my difficulty finding the brake bite point on descents & in group rides, & the numerous problems caused by trying to coerce my 105 hydraulics to behave more like rim brakes, I just went 
f*** this & swapped over to the mechanical TRP Spyres. Got the LBS to do the recable job. I rode that bike with hydraulics for 18 months & still couldn’t get used to them; I think I gave the system a decent chance. Not for me.

I’m not a good mechanic.
Bought these two tools
Watched a SRAM video, talked to a mechanic, and was good to go.
Only have LBS do an annual bleed.

+1. Those two tools make putting in new brake pads easy!
The rest of it though… pain in the backside.
I don’t get it. Bleeding my SRAM hydraulic disks takes about 30 minutes a pair. Just followed the instructions.

Brake adjustment is easy, even when swapping wheels. Loosen screws, grab brake, tighten, done. Sometimes I’ll screw up and forget the brake spreader and touch the brake. Hence the two tools.
Ha ha that never works for me. Even using a business card. Even using the Hayes feeler gauge like thing. Always end up doing by eye once it’s close. I’ve never even seen that work. Maybe someday.
But I bled my brakes after shortening the hoses before a trip to Leadville. Didn’t have time to ride beforehand. And the suckers worked. That was…… handy. …

Well, they both launch rockets…
