comment Choosing good slick tires for a MTB
@Vorac - Certainly, if you JUST decrease tire width it likely increases rolling resistance (especially if the tire gets close to "flat" condition as a result). But also increasing pressure results in a smaller contact spot, which is the main determiner of rolling resistance. (That article also continues the old canard that weight on the tire severely impacts acceleration. There is an impact, of course, but it's slight.)

I didn't know that riding against traffic was legal anywhere in the US. It's certainly in contradiction of the "model law" that many states base their cycling laws on.

comment Turtles on Trails
I have, on a couple of occasions, gently moved a turtle to a reasonably sunny "hard pan" spot off the trail. Not sure if it's the best thing to do, but it's doing something.

comment How should I prepare a carbon frame when I want to swap in a new bottom bracket?
One minor point: Creaking from the BB (at least in a standard setup) can be due simply to the cartridge being loose between the cups. For a glued-in BB it can probably be due to the glue being somewhat loose in spots (similar to a creaky handlebar). And of course when one hears creaks from the BB the first thing one should do is tighten the crank bolts.

comment Converting Mountain Bike for Road to complete in 33 mile mini triathalon
Yeah, if you can lock out or disable the shocks somehow that would be good. (I've occasionally wondered if you could purchase pieces of plastic drain pipe of an appropriate diameter, slit them in half lengthwise, and strap them around the shocks, to disable them. One would, of course, need to be careful that the pipe didn't bear on the shock seals in a way that might damage them.)

Buy wheels, not just rims. Swapping rims (and then swapping back later), while certainly possible, is not particularly practical. (Or just find the narrowest, smoothest tires that will fit your current rims.) (It wouldn't hurt to describe the bike a little -- current tire size, etc.)

comment Topeak Explorer Tubular Rack two versions confusion
Yep, people often don't understand that the straps running to the seat post or brake bolt are intended to be bent to fit.

comment What type of tires have tubes inside?
Also, in the past "tubulars" were often referred to as "sew-ons" or "sew-ups", since to repair one you'd open up the stitching on the inside diameter, extract the tube, patch it, then sew the casing back together.

comment What type of tires have tubes inside?
FWIW, historically a "clincher" was a tire/rim combo where the rim had J-shaped hook cross-section on the edge of the rim, and the tire had a corresponding J-shaped edge molded in, with no wire bead. Thus the two "clinched" each other. However, the term "clincher" has come to mean the modern wire-bead tire.

comment Bottom bracket cup doesn't fit on non drive side
Was the box opened? My guess is that they took several BBs out of their boxes, trying to fit a bike, and put the wrong cups back in the wrong boxes. What you have on the left is probably a French or Italian cup.

(I vaguely recall seeing a BB like this once, with different sized cups. But I can't remember where.)

So the above picture is of the replacement cartridge and the cups that came with it? Is this salvage or "old new stock", vs a newly purchased unit? Looks to me like you simply got a weird bird cartridge -- a non-standard unit.

comment repair scratches on surly frame
What I recommend (if you're inclined to fix it at all, which is totally optional) is auto touch-up paint from an auto parts store. It is often available in small jars similar to nail polish jars, with a brush in the lid (or even in "pens"). And the auto paint is a good choice in terms of adhesion, durability, etc.

comment Bottom bracket cup doesn't fit on non drive side
Actually, having the drive side cup permanently fastened to the cartridge is a bit of an aberration, but a common one, since that's how Shimano generally does it. But you may have to find a different cup at your bike shop or wherever. (Does the right cup have the same unthreaded section?)

Well, that's not what the blurb says.

comment Bottom bracket cup doesn't fit on non drive side
First, does the cup not fit at all, or does it simply not thread in all the way? If it doesn't fit at all, have you verified that the threads on both cup and bracket housing are right-hand? Where did you get the new BB from?

comment What are the benefits of nickel-plated chains?
Pretty much all purpose-made chain lubes provide some degree of "coating" that would prevent corrosion. Dumonde Tech says "Plating bonds to chain; can’t be washed off!"

comment What are the benefits of nickel-plated chains?
Mostly looks. The nickle will prevent corrosion, but a chains should be sufficiently well lubed that corrosion isn't a problem anyway. In theory the nickle might reduce friction slightly, but that assumes that the parts you can't see are also plated, and even then the benefit would be slight.

comment In which orientation should a front wheel be installed?
With regard to skewer lever orientation, I heard many years ago of a case where someone drafting managed to (quite unintentionally) get their tire behind the rear lever of the bike ahead and flip it open, causing the wheel to come loose. And of course the same problem can occur when riding by a bush or whatever if the lever points forward. So probably upward is best both front and rear.
