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.
To pick the right size bicycle, you want to measure your height, and specifically your inseam (inside leg), in proportion to the size of the bike frame. The inseam measurement determines the seat height, or the “stack.” Next, you must calculate the “reach,” which is the horizontal distance between the bottom of the frame and the head of the bike -- or, in layman’s terms, the distance between seat and handlebars.
A two-stage hand pump tries to marry the best features of both types of pumps: the quick inflation of high volume that can achieve the higher psi ranges of high pressure. But to steal a quote from our floor pump guide, “You pump eight times or you pump 10 times—what does it matter?” That’s a quote from Daimeon Shanks, who at the time was a mechanic for the Garmin-Sharp pro tour team—that’s right, Tour de France, baby.
We rented a tandem bike from here for an hour, and they were super chill! We dropped by on a Sunday and decided to go eat first; Andy, one of the owners, was awesome about holding the bike for us while we went to eat before renting. We enjoyed our ride for just over an hr, but Andy was also super relaxed about our return time and only charged us for an hour. We had a fantastic time and would definitely recommend renting bikes from here!
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.
