comment Switching Parts to a New Frame
Typically, 120 mm spacing in the rear is for track frames, 130 mm for road, and 135 mm for mountain. I think 135 mm is becoming more common on road with frames that accommodate disc brakes, larger tires, etc.

comment Why are higher-end freewheels so much louder when coasting?
I seem to recall reading that Shimano designs their hubs to be quiet. Or perhaps it's that their hub design is inherently quieter. Something like that.

Great answer. I would like to mention that more points of engagement become particularly using with mountain bikes -- especially when ascending a technical section in a very small gear. I personally don't see the need on the road.

comment Buying first hybrid bike; better to put $ into components or disc brakes?
hmm. then perhaps the answer should be clarified by saying, "in this price range, you'll likely want to avoid suspension and the quality of the disc brakes might not be satisfactory compared to ..."

does it rain a lot where you live? if not, i wouldn't worry about disc brakes. even if it does, it's a toss up, IMO.

I don't think the OP means mountain bike trails. Sounds like he's on paved (or at least well graded) multi-use paths.

comment Is front-suspension a false-economy for cheaper bikes?
Trials bikes don't come with suspension, but dirt jumper bikes do. My point is that it's not even worth mentioning (unlike non-subjective points like weight, maintenance, etc).

comment Is front-suspension a false-economy for cheaper bikes?
So much of this is subjective. You definitely learn to pick a line riding rigid, but that's about it. The techniques are different, but it's too subjective to say that jumping or tricks easier with or without a suspension fork. And why even bring up falling? Maybe you fall slower, but more often?

comment Tubeless conversion on schrader valve rims
The first two notes on the page mention Stans rims specifically. The third note muddies the waters, but upon re-reading it, I now believe the article is meant to be more general than just Stans rims.

It appears that list is specifically for Stans rims. Am I misunderstanding that?

Thanks. That's helpful. I've never seen a conversion kit up close.

That link is very helpful, and I think I understand what you mean. But what 20-in tube are you talking about? Could you clarify a bit?

comment Why do Mountain Bike helmets have visors?
@vclaw, how exactly does a visor above your face keep mud from hitting it from below?

comment Why do Mountain Bike helmets have visors?
my 2 cents: to arbitrarily differentiate them from "road" helmets. no other reason. if the sun's in your eyes, sunglasses and a cap do wonders.

comment Is there any advantage to preparing the tire bead with sealant during installation on the rim
Ahh -- I totally get that. Plenty of broccoli here in Oregon.

just curious: what's "broccoli" in this context?

comment Should I not use a trail because of poor conditions?
@Vorac If you're skidding and drifting, you do have more impact on the trail and you should modify your behavior. IMBA trail design guidance mentions best practices on how to limit the temptation to skid. But as a trail user, you have a responsibility to ride in a manner that minimizes trail impact (i.e., don't skid!)
