Bicycle Tire Savers & Sheldon Brown Nuts
I've come across some well-priced bicycle tire savers by Bicycle Research, and I have a ton listed on eBay. They've been selling pretty well, and I figured I'd make a quick post about them.
These are one of those bike parts that you are unlikely to find in your cycle local shop, and you'd probably be the butt of the day's wrench jokes if you asked for them. (Heck, most of your bike technicians probably have no idea what they are.) They are certainly a device of yesteryear, but would be revolutionary for today's road cyclists. They simply mount off your brake caliper bolt and sit close enough to your tire that they knock embedded glass away before it has a chance to push deeper through the tire. And at a whopping 16 grams, I think you should install them instead of changing a flat tire in the Texas sun. Not to mention, your set of $140 Vittoria 320TPI Open Corsa tires will thank you.
These tire savers or "flint catchers" were much more popular during the days of long brake caliper bolts with exposed nuts on the back of the fork and seat stay bridge. Nowadays, it's rare to see that style of brake bolt on a quality bike, but there is a work around. Check out Sheldon Brown's "Sheldon Fender Nuts" which also allows a fender-mount on frames & forks with recessed brake nuts.

Cleaning the Sachs 3x7
Recently I picked up an older Sachs 3x7 hub, and I really love the machining on it. I haven't worked it into a project yet, but I will hoard it until I figure out what it's going on. It was still sticky from really old nasty grease in it, so last weekend I bathed it. I took the time to disassemble, soak in a degreaser overnight, and scrub. Be nice to your hubs and they will be nice to you!
Afterward I gave it an oil bath, regreased the bearings, and reassembled! Just waiting for the right frame to come around for my next project.
