Considering what happened at Altamont...

What kind of chamois cream do you like? My post-apocalyptic store of DZ Nuts is coming to an end and I'm wondering if I'm missing out on something better.

Yacks uses Bag Balm for post 3 hours + rides...when I'm probably a little chaffed
My daily driver and what I've been using for a year now is this stuff...pretty cheap on Amazon and can also be used as a daily moisturizer for the limbs
 
Looking for recommendations on quick release replacements for commuter-ish bikes.

Anyone have a feeling about Pinheads vs.  quick releases that necessitate flipping the bike upside down vs. another option?

Also @JohnMalcolmson, I seem to recall you mentioning a putty to put in hex head bolts on things like handlebars.  What was the stuff?  
@mugwump they’re all about the same in terms of just trying to make it incrementally harder for somebody to steal part of your bike. 

The big consideration for you is which type of tool do you want to carry,  a special tool or a 15mm wrench with you just in case you need to remove a wheel. 
I've used the pinhead skewers (seatpost and wheels) and never bother to lock wheels. 10 years without issue, but you could definitely get them off with vice grips, so don't recco overnight. It's a nice feeling because you just lock your frame so lock/chain can be smaller. Minus is if you puncture and don't have the key. I haven't seen the gravity skewers, nice idea. 

I put two-part epoxy in bolts and blue Loctite so they don't turn super easy (but also ensures they'll never seize). To make adjustments you'd have to gouge it out, or perhaps have to use heat, I haven't had to yet. Some people glue in a small ball bearing (saves you having to have the bolt level with epoxy). If you want to be total badass, you could buy security bolts where you need special tool.

I'm liking the ball bearing and glue idea.  Seems like that could be picked out in a few minutes, which is probably enough.

It's for a bike for Oscar.  We're commuting and now that he's moving on to a bigger bike that come with quick releases, I'll want to slow that down.  I'll need to be able to adjust the saddle and bars as he grows, and he doesn't ride enough to justify having multiple bikes.  yet.

The Pinhead design is interesting because it functions as a slow release, and you can get multiple "keys".  I figure it's something you'd keep with whatever key ring has the key to the lock that goes with the bike, which is about the same as having to travel with an Allen key, though everyone has an Allen key if you lose the one that goes with the bike.

Got mine the other day.

They've improved strap placement a good bit, and they've taken care of the slippage issue I was having. The fit does seem closer, though I haven't tried putting anything between my head and the helmet yet to see if that has changed.

And the new fluo orange is the hotness, especially after the fade of my Octal (three years old I believe).

sealant review!

so before I left NYC I bought a one gallon jug of Finish Line's new sealant.

i'm switching back to stan's, this stuff just doesn't seem to seal as well.  on my road bike I end up getting sprayed by sealant every single ride, usually end the ride with 50% PSI drop in one tire.  same tires had no issue when running stan's.  tires are new enough that the seam down the middle is still visible

oddly, i haven't had any issue with my CX tires.  maybe it works better at low pressures?  maybe the trails/grass i'm riding on just aren't as likely to puncture the tire?

it does wash up nicely with just water or soapy water.

the selling point was that it never dries out but the convenience of that is negated by how frequently i have to add more sealant and how frequently i have to clean the sealant off my bike and oh yes, how frequently i end up with a 50% pressure drop

i thought maybe it was just that some of the the roads up here are different, i'm riding on some more gravelly stuff, but if you look around the internet the experience is widely shared.  mtbr.com gave it 2/5 and everything in the review is consistent with my experience

i really wanted to be able to recommend this sealant, especially because ex-kissena Dave Vollbach works there, but after using it for a month or two i can't recommend it to anyone

tldr don't buy finish line sealant until they come out with version 2.0
I was considering trying that stuff myself since I don't have a way (or room) to set up road tubeless tires myself... always schlepping them to the LBS.

On the topic of road tubeless, has anyone used these repair plugs? 

https://www.amazon.com/Innovations-Tubeless-Tire-Repair-Kit/dp/B01EOMTI0M
yes, i used them on road tires (Schwalbe One Pro 28mm). a patch is a better long term solution.
@Brendan Rigby thanks for that. I just reinflated my MTN bike tires and the sealant appeared to come through the sidewalls as if the tire was porous. I didn't loose pressure and it doesn't still seem to be leaking. Is that a thing?
Yes that is a thing... sidewalls are porous and better tubeless tires are
less porous. But if you have amazing airproof sidewalls your tire may not
ride well. Manufacturers pick a balance and you pick the tire you like

T47 Bottom Bracket standard.

Dimensions of BB86, but with threads.
Right now, it's pretty much limited to custom US builders.
Some techies like it because you get the oversized wide shell, which means easier to build light, stiff frames, and hidden bearings, but can tighten cups--and if it goes south, you replace the cups, not trash the frame.

On the bad side.  Another standard.  And metal threads add a little weight.  
I found the bike (I think) that fits my needs:

Thru axle
Can run both 700cc or 27.5 wheels
Sub 1000g frame

But it's got this crazy new BB and apparently there isn't enough clearance for a stages pod.

Those are the bikes than the Clif/Luna Women team races cyclocross on (they put Orbea stickers on them, tho) 

Also new to the 2018/19 market:

^oooh, beautiful
Not as much tire clearance as I'd like tho.
Shame Miller rides the new Shimano power meter, the results are not great.

There's a slew of new bits at Eurobike, including tons of useless crap, like a whole zero chain 99% efficient drive train, and a $250 smart fan.

So far, two pieces of equipment have stood out for me. Wahoo has released an updated kickr, same like the old kickr, but virtually silent.

And a new $800 retail Kickr core -- still direct drive:

Wow that is seriously quiet.
