comment Why don't race bikes have solid front triangles?
But that frame doesn't have a triangle at all.

comment Mini Pumps For Roadbike (120 psi)?
Note that the Morph G (13.5" long) isn't really a "mini pump", though it's shorter than your standard frame pump. Your classical "mini pump" is about 8".

comment Mini Pumps For Roadbike (120 psi)?
Understand that the length of a pump affects both the rate at which it pumps and the max pressure it can achieve. There is an amount of "dead space" at the top of the cylinder that is pretty much fixed regardless of pump length. And max pressure is essentially determined by overall length divided by dead space length. Plus, of course, air volume is also directly proportional to pump length. These considerations make a frame pump much more attractive than a mini pump.

comment Do quick release wheels require certain design in the fork?
Yep, you should be able to use a QR hub with no problem. You won't have "lawyer lips", but bikes with QR axles didn't have those for decades and the world didn't end -- they're basically just for people who are too stupid to get the QR clamped tightly enough.

comment Custom/universal clamp/attachment for light on rear rack
You usually have to be creative. I've a couple of times used a angle bracket from a hardware store, once combined with a screw-type cable clamp.

comment When is a bike frame considered too tall?
When you start singing soprano. Well, actually, the usual rule is that you can stand flat-footed over the top bar (of a standard diamond frame with horizontal bar) with "comfortable" clearance (an inch or two, in bike shorts). But fit also depends on the length of your arms and torso -- if your arms or torso are short relative to your legs then you need a shorter frame. (Exactly how frame size is measured, alas, depends on the person measuring -- there can be about 2" difference depending on the "standard" used.)

comment Pedal arm inside pedal screw hole stripped
I think the net-net is this: Take it to a bike shop and bite the bullet. Either they can repair it or they will install a new crank arm. (And given your problem with the pedal I'd not suggest you attempt replacing the crank arm yourself.)

comment Pedal arm inside pedal screw hole stripped
I would be skeptical whether such a product would hold up against the lateral loads presented with a pedal.

comment Pedal arm inside pedal screw hole stripped
Important question: Is this the left pedal or the right? If the left then you're probably SOL. If the right then it can be bored out and a "helicoil" installed (though this would need to be done by a skilled mechanic with the right sized helicoil). Probably you'll need to replace the crank arm.

comment Wheel spokes & strength
A little marginal, in my opinion, but you might as well use them until they give you trouble (if they do). A lot depends on your riding style.

comment What is a simple mnemonic for remembering the thread direction when removing pedals?
It's kinda like "Fall forward, spring back."

comment Cause of spalled cones?
Brief follow-up on this: I'm reasonably convinced that the problem is a bent hub. Hard to say how long it may have been bent, and even harder to say how it got bent (I don't even take bumpy roads fast), but a very slight misalignment between the two ends would produce the symptoms I've seen. Replaced with a new wheel from Peter White.

comment derailleur P-screw/B-screw does absolutely nothing
I'm trying to figure out how that's even possible. The chain sits between the jockey wheel and the sprocket and they move in synchrony, so there should be no "grinding", even if they touch. But normally they should maintain about a half-inch separation from chain tension alone, unless the sprocket is too large for the derailer.

What is it? It's weird!

comment Why don't race bikes have solid front triangles?
Same reasons for not using disc wheels. Plus it would likely not improve aerodynamics much (if at all).

When you say "noticed grind", what do you mean?

comment Aerodynamic kid's trailer with suspension
A hard shell would add at least another 20 pounds weight, more than offsetting any advantage from the (hopefully) aerodynamic shape.

comment Aerodynamic kid's trailer with suspension
I think "aerodynamic kids trailer" is an oxymoron, especially when you add on the ability to haul another bike. Best you're going to do is one of the units with a canvas cover.
