Otherwise, this tool should serve the average commuter well. Specifically, we think you’ll find the size 4, 5, and 6 hex keys, extremely common sizes in bicycles, very helpful. They’ll adjust seat-post heights or let you remove the saddle entirely, or tighten a loose stem that’s always rattling apart. The Phillips head will tighten loose bolts on shoe cleats or the rear derailleur. The most common use for the torx would be adjusting disc brakes if you have ’em.
Basic first aid supplies: A few bandages of varying sizes. 6 Aspirin, or other OTC painkiller of choice. A few alcohol pads in sealed foil packs, useful for cleaning grease off grease and grit off of the bike, and also cleaning cuts on yourself if you take a spill. 1 day supply of any prescription drugs you need to take regularly. Wrap these up in tinfoil and tuck away. It might just save your day.
The Knights Helping Knights Pantry is a student driven program at the University of Central Florida with the goal of assisting students through financially tough times. Donations that are either brought to the Pantry or are left in one of our 15 drop boxes on campus are provided by faculty, staff and students. Student organizations, departments and individuals on campus also organize food drives that benefit the Pantry.
Basically, you’re stuck with toggling between systems for the advantage of a few pumps, and it doesn’t seem worth it. In the original iteration of this guide, I tested 12 pumps and inflated three different tires completely full to their psi rating, and measured how many pumps it took. Yasuda did similarly for his revamped full-length exploration. That’s 36 tires, and I can guarantee there is no difference between 50 pumps and 100—it’s all terrible.
Next, two-stage designs. There are two types of hand pump. HV (high-volume) pumps, ones that pump a lot of air but don’t have a lot of pressure, which are used for mountain bikes. The Lezyne Alloy Drive is a high-volume pump. Then there are HP (high-pressure) pumps, which pump a small amount of air but can inflate to very high pressures and are used on road bikes. Our top pick is a high-pressure pump.
Owning a bicycle is a good idea, but taking care of it yearns for an experts’ piece of mind. You should not worry too much about taking your bicycle to a mechanic when you can handle the repairing on your own. It will rather save you the cost of every moment you get into a problem. Grab a pick of one of the toolkits from the above review. I assure you that, absolutely no day will you seek a mechanic for service.
Patch kit: Patch kits are easy to use, light and compact, and if you get more than one flat on a ride (it happens more than you’d expect), it can save you when you’ve already used your spare tube. Plus, on a rear wheel, patching a tube can be faster than replacing it, as you can often do this without removing the wheel at all. Another upcoming post is going to show you how to patch a tube.
Bike Radar gives the Pedro’s levers 4.55 out of five stars and claims they’re the “best out there.” (Can we pause to admire the extra five hundredths of a star the site chose to award it? Very specific.) Aaron Gulley, writing for Outside, states, “I can’t count the number of times I’ve snapped cheap plastic sticks, shredded my hand in the process, stomped around cursing in pain for 10 minutes, and then, insult to injury, been tool-less and unable to get my tire off anyway. That will never happen with Pedro’s.”
It’s both surprising, and not, if you think about it. The way I’ve usually seen it happen is first the rear tire goes flat, then the front one. My theory is that both tires went through the same pile of glass/thorns/metal bits and they both picked up junk. the reason for the flat occurring on the back first is because there’s more weight on that tire, so the offending article works its way through the tread more quickly.
Modern bottom brackets use a sealed bearing type construction that keeps water and debris locked out, so they seldom go wrong. Maintenance is impossible so they need replacing when they do wear out. Older style cup bottom brackets need to be re-greased every now and again, and occasionally will need to have their bearings replaced. There are a lot more teeth on the chainring cogs than those on the rear cassette, so need changing less regularly. Cranks usually a solid one piece construction so there is not much to go wrong.
