The retractable tube is stored inside the body of the pump when not in use, and it can attach to either a Schrader or a Presta valve, the two types of valves you’ll see. Some pumps can accommodate only one type, making them less universal. Toggling between the two is simple, which can’t be said of other models with itty parts that require nerves of steel to handle on a good day, let alone while wearing gloves, crouching in the wind, oblivious to the sewer grate a few feet away.
Let me go ahead and get the bad stuff out of the way. First of all, this stand is NOT the same level of quality as something you would find in a bicycle shop being used for the shop's repairs. it's quite a bit more flimsy, and the grip likes to rotate if you don't get the bike's center of gravity just right. The tool tray is also made out of a rather cheap plastic that can break easily at the rim. That being said, this stand is perfect for home users and makes mundane tasks like fixing a flat or cleaning the chain much easier. It easily holds my Raleigh Merit 3, and I don't worry about the thing falling even if the grip tilts a bit. The stand significantly shortened the time I needed to change an inner tube on my bicycle, and made me less worried about damaging something on the bike by jury-rigging a stand out of whatever I had lying around.
I just got a tune up on my bike and it rides so much better now! It takes half as much effort to petal, it is like a new bike. The guys who work there are so nice and always make you feel like your time is important. They don't overcharge or sell you things you don't need. I thought for sure I needed a new chain, but as it turns out, it's fine! He gave me some extra foam for my bike helmet, free of charge! I'll definitely come back here for all my bike needs!
Since then, I’ve found a few decent alternatives to my dilemma: The Venzo Pro Mechanic Stand that runs at about $88, and the Cave Competitor Service Post for $59. While there are other alternatives out there—sometimes cheaper ones—these are the two that I think are actually worth the price. I can’t really vouch for any others out there. But there just ain’t getting around this one. You’ll need something to hold your bike while you work on it.
Brakes come in a variety of designs depending on the age and style of your bike. Rim brakes offer more modulation but have less stopping power, so are more suited to riding on the roads. Disc brakes can provide huge amounts of stopping power so are best suited to off road riding, although ‘V’ rim brakes are also well suited to mountain biking. All brakes use a friction system to stop the movement of the wheel, so regular checks of the contact pads should form part of your regular cycle maintenance.
