Our favorite hand pump for commuters is the Lezyne Sport Drive HP, and you can read more specifics about why in our full-length guide, written by Dave Yasuda, a writer and tester with over 30 years in the saddle. To sum it up, Lezyne makes pumps with an extendable rubber tube that connects to your tire valve, and that’s the difference between awkward and demoralizing. It’s not the only company that does so, but it is one of the few, and it does it the best. The Sport Drive HP can adapt to any tire valve, has no small fussy parts to lose, and inflates more easily to higher psi levels than anything we tested without floor leverage.
I brought my bike into Kyle's shop to fix the noise in my rear wheel. The mechanic suggested that I need to overhauled the rear hub for $30. The next day the noise came back even worst. I brought it back to the shop and they said it was the freewheel driver not the hub that needed to be work on and it would cost me extra $30 to overhauled it again plus the part to fix it. At this point I walked out of the shop and took my bike to David's world. The mechanic at David's world took a quick look at the rear hub and indicated that the axle was put back too tight when Kyle's mechanics were working on it and further identify the issue. I ended up paying David's world the $30 plus part to fix my bike, but the major different is that David's World has 30 Days services warranty claim. If you have any issue with your bike within the 30 days the service was performed you can bring it back and they will fix it no question ask.
We like, and recommend, the Crankbrothers Speedier Lever. If you have to pick only one, go with the Pedro’s, but if you want a backup or have some hard tires to unseat, Crankbrothers is a great choice. It’s only one lever (as opposed to a set of two, like the Pedro’s) and it’s longer, so we didn’t pick it over the Pedro’s for portability reasons. But it’s an excellent tool. It has a wide handle you can grip with your whole hand. Like the Pedro’s, the tip is the right size and shape to prevent slipping and stay in place, and the shape of the handle happens to protect your knuckles if you do slip. Even in situations where I didn’t need it, I liked having it because it made me feel like a pro.
Any bike that gets ridden seriously as transportation or on long rides needs at least a basic tool/emergency kit, and the knowledge to use it, unless the rider is always in a position to call a friend with a car or a cab when their bike needs a quick fix on the road. If you never travel more than a few miles, this can be overkill, and calling a friend or a cab may be just the ticket, but if you want to be more self reliant, this is something you should seriously consider. This list may sound like an awful lot of stuff to carry, but really, it only weighs a few lbs and fits in a small, under-seat bag that comes off quickly so I don’t have to leave it with the bike if theft is a concern. If you always carry a regular rack top bag, you can also just put all this in a small nylon bag and throw it in there, but I prefer an under-seat bag.
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.
