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.
For the budding mechanic: A good pocket sized repair guide. One good option is the “Pocket Guide to Emergency Bicycle Repair” by Ron Cordes and Eric Grove. It’s only 3.5×4.5 inches and a half inch thick. I don’t carry this myself, but for someone who’s new to this whole bike repair business, it’s really helpful to have. A future blog post will cover this book in detail.
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.”
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.
