How does a bike's weight affect the overall experience of owning it?

Naturally, carrying a light bike up the stairs is much more enjoyable compared to a heavier bike. Are there any other aspects of a bike which are affected by its weight? For example, would the weight affect handling at low speeds? Higher speeds?…

Is this rim still safe to use?

I bought it this way without the seller noting the issue, so experience from riding with these is zero. Rims are Ritchey Girder OCRs. The crack is pretty small, but noticeable, and I will be running Maxxis DTHs on it, so I will pretty much load the…

Purpose of 'bore' on spoke nipples - why are spoke nipples not threaded through their entire length?

I noticed that (most) spoke nipples have a thread which does not run through the entire length of the nipple. As can be seen in the image below some of the length of the nipple has no threads (and is called a "bore" apparently). This left me with…

How dangerous are my worn rims?

I took my bike for a service recently and was told it needed so many repairs that it was more cost effective for me to replace it. One of the repair jobs was to replace the wheels due to worn rims. The shop told me they were so dangerous that they…

Rear wheel slipping out under load

My commuting/cyclocross bike (a Surly Crosscheck) has a problem. If I tighten the quick release skewer to a normal level, sort of firm to close it, then if I step on the pedals hard at some point, the rear wheel basically comes right out of the…

What causes tire sealant to seal?

I've heard from others that air is what causes sealant to seal. People have said they've read that "somewhere" but I never seem to be able to find those articles. The reason I think air can't be the sole factor is that there is air inside the…

Next year I might find myself needing a lightweight touring/camping shelter, suitable for overnight stops at camspites and at the roadside. One option is a single-hoop bivvy tent (example) but many of these aren't much lighter than my hiking tent,…

Properly locking on a floor mount rack with a U-lock

I have read recommendations to lock both the bike's frame and wheel. That's quite easy to do on larger racks, such as Sheffield stands. The place I work in, however, has a floor mount rack to store bicycles, with semicircular shaped supports. If I…

New high quality tire doesn't sit evenly on the rim

It's my first tire change experience and I got so far using youtube videos but now I'm stuck. Got these Schwalbe 365 tires yesterday for my folding bike. It is an all season model which feels a bit harder than the tire that was on the bike from the…

Safest way to store bike outside (city)

I bike commute and just moved to a tiny third floor walk up. I was willing to give up some of my precious space to store the bike, but it turns out that the narrowness and curvature of the stairs makes it extremely difficult to get the bike up and…

Why using a puncture repair kit instead of a new inner tube?

I am a casual rider (~30 km commute as often as possible) in an urban setting. Reading this SE site to learn about biking (the resource is extraordinary, even though I don't understand every technicality) I see that one of the suggestions given on a…
