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.
There are patches that don’t require vulcanizer—the infamous peel-and-stick. One brand, the Park Tool GP-2, has some genuinely enthusiastic endorsements, so we tested it. I applied Park Tool patches to four different tires, at three different psi levels (60, 90, and 120). Three of the four didn’t hold—two released within minutes. The fourth deflated overnight. I redid the test, but repeated a second time, they all leaked within a day.
I chose to test these four levers after eliminating everything out there that’s not appropriate for a roadside emergency kit. That includes metal levers. They’re durable, but according to touring cyclist Ramona Marks, “Metal tire levers are trouble. It’s possible to rip your tube even with the plastic ones if you’re not careful, so metal is out of the question, and you don’t want to put pressure against the wheel rim with a metal lever.”
Mountain bikers are in different world of repair entirely, one that borders on the comedic absurd. It includes large pumps designed to fill up big, fat tires that squish over things, and a medley of assorted slimes meant to be injected into tubes or tires. In that world, the number of days it takes you to fix your tire and return from the wilderness is a badge of courage—bonus points if you’re bleeding—and we’re guessing that’s not what you’re going for next time you set out for groceries.
First, I researched. I looked at Amazon’s top-rated products and their user reviews. Then I consulted Bicycling magazine, Gear Junkie, Bike Radar, Outside, and the occasional bit by Lennard Zinn via Velonews. I also found some worthwhile discussions at Bike Forums. Then I spoke with four experts, Ramona Marks, Scott Karoly, Cari Z, and Alison Tetrick, riders from all across the spectrum, who tour, repair, and race.
Don’t rely on others. “People need to recognize that now there are different cassette sizes, so there are different chains depending on what gear you have. A lot of people are like, ‘Oh my friend is always prepared they always have the stuff, I’m not going to bring anything.’ All of the stuff now is very bike-specific, and you have to have your own package of stuff.”
Good bike repair stand. I can't say "great," because it arrived with some small plastic pieces broken. These are small pieces that go between the legs and the supports for the legs to act as a sort of buffer to prevent metal to metal scraping. They are just too fragile, it seems. 3 out of 4 legs had these broken upon arrival. However, these are really only "nice" to haves, not need to haves, and they don't really detract from using the stand in any way. Once you have the stand set up, you don't worry about these at all. The main clamp holds the bike well, if you take care to balance the bike properly. The bike may tilt in the stand if you don't balance it - there is a weight limit to the clamp. I like the included tool tray, but I wish it was more adjustable in height (it is essentially fixed in one position). And the tray could be larger. Otherwise, I am quite happy with this stand. I have worked on several bikes using it, and assembled one out of the box. It makes the job of doing things like adjusting brakes and indexing derailleurs so much easier. The price of this stand is excellent considering the quality.
That’s a reality of all hand pumps—it’s really hard to get a tire up to pressure with these things. So another reason Lezyne pumps are so good is because you can actually keep pumping longer than any other brand we tested. With excruciating effort, we could get the Sport Drive HP to pump tires to 90 or 100 psi. It still wasn’t easy, but it wasn’t impossible the way it was with some other models.

A wrench that fits the hub nuts: If your bike has quick release front and rear wheels, you don’t need this, but if you have an internal hub on the back, such as the NuVinci, a wrench that fits is a great idea. 99% of the time, this is a 15mm wrench, but you should check your bike. A 6 inch adjustable wrench can also work, but it will be heavier, and when using an adjustable wrench, you do need to take more care to not round over the nuts. A fixed wrench is the best choice. Some multi-tools have a 15 mm wrench built in, but again, if you have limited hand strength, something with more leverage is a great idea.
Nice, helpful, friendly. Central location. Good bikes (I had two over two days.) Bikes had a water bottle cage (some places don't do that!) Provided helmets if needed (I didn't) and a one-sided pannier containing a decently strong but not super-heavy cable lock and a patch kit. Only quibbles: 1) The owner helping me with getting my bikes seemed to 'drop me' for too long when someone else walked in. He should have said to them, after asking what they were in for, that 'I'll be with you as soon as I'm finished with this person.' So I had to wait a little longer than desired, but not bad. 2) On my second day, the pannier bag fell off and got lost after I stopped for lunch, which required locking up the bike somewhere, so I took the bag into restaurant and re-attached it using the two velcro straps on the rear rack. I've used many panniers before, thought I did it correctly. But apparently I did not. So I paid $55 (cost) to replace everything in bag and bag. In hindsight, I wished I'd put a bungee around bag straps to really secure it to bike. PROBABLY MY FAULT. 3) Bring a second lock to lock quick-release front wheel, as decently strong but not super-heavy cable lock isn't long enough for both wheels and frame.I had a second cable lock.
These guys are awesome. After work, I got to my bike to discover my back tire was completely flat. It had a slow leak, so I was able to pump it up enough to make it to their shop. I got there 10 minutes before closing and they were able to fit me in. They replaced my tube and picked all of the glass shards out of my tire. Awesome customer service and they saved me from having to do this myself in the dark and the cold.
It has some useful information for basic repairs... not so heavy on the maintenance side but there is some in there. The pictures and drawings are in black and white, but mostly visible. Only a few are difficult to see. However, they are in 2-dimensions and they don't show you HOW to do the thing, they only show you the general area and the part you want to manipulate. The phrasing in the instructions can be hard to follow without a good visual reference unless you're already a master bike mechanic (which you aren't if you're thinking about buying this). So, buy this for general reference and rely on Youtube for video. The two together are better than either one alone.
If you are planning on going on a multi-day ride or just riding a long distance in a day, you should have something for first aid, just in case. Unfortunately, almost everyone who cycles frequently will go down at least once in their life. This kit can be really small and compact and can include bandages, some gauze, and a small bottle of a disinfectant.
