The thumb test is the fine art of pressing on the tube with your thumb to see if it’s inflated. During testing, I took a pressure reading out of curiosity, and to the touch, road tires feel fully inflated around 30 psi. How pathetically sad—30 psi!—when you’re probably trying to reach at least 60 psi on a mountain bike, 70 or more on a hybrid, and it only goes up from there.
The Bicycle Repair Shop does rentals by the hour or by the day. They have reasonable rates. They have solid, lightweight hybrid bikes so you can tackle train tracks and brick streets and hills. They also have road bikes for the more experienced. You can reserve online in advance. You get a helmet and a lock with your rental. The staff in the shop are friendly and will suggest routes and point out hills if you're new to the area. And believe me these hills are no joke!
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.
First, carbon. You already know you don’t need it for your casual weekend pursuits, because you’re not counting ounces the way a professional road racer would. But to quote an article from Velonews, “Remember that professional athletes operate in an entirely different environment than the rest of us. They are all very close to each other in terms of fitness, and they are also all very close to being the absolute best a human being can be. In short, you’re much better off upgrading your legs and dropping body fat through proper training and diet.”
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.
