Checking for Chain Wear

Last week I checked my chain for wear using the Park Tools CC2 (thanks to SP), and I read up some stuff about chains and wear generally, and here's a jist:

Locking a Quick-Release Wheel

I noticed at least two bikes in campus being ridden with the QRs not correctly locked. The proper way to use the QR is to use its cam, and not as a 'handle' to tighten the nut on the other side. Most QRs have "open" and "close" etched on them - if you can read the word "open" your QR is not locked.

Saddle Selection

Saddle selection has been a sore point (it's not a joke if you're suffering) for many potential bikers. With an uncomfortable saddle, a new rider will most likely just give up biking. Luckily I came across a nice article on saddle selection, one that covers the anatomical aspects as well. The article is on the cervelo website, and is well illustrated too.
