Messing with a used bike will teach you a lot (mostly through mistakes, but that's how the process works). There definitely is a huge advantage of having hands on experience figuring out how to adjust ...

Choosing a rear derailleur for 11-42t cassette on a SRAM 10-speed 1x system

One confusing thing here is that SRAM themselves, that I know of at least, have never made or warranted a 10 speed 11-42 1x setup. So you're not going to hear from them or their product documentation ...

Ideal distance between chainring and chain stay

4mm at the closest point is about the safe spot. 3mm is about the sane bare minimum you can go to if you want to push things. Less is asking for trouble. Note that frames, cranks, rings, and spindles ...

Questions about Boost frames and cranksets

You are correct. The cassette hasn't moved, so the rear chainline hasn't changed, so you don't need to compensate for it. Note however that a non-boost crank in a boost frame might have chainstay ...

Getting the right Bottom Bracket

If you have an idea of what model of frame it is, it would help. Otherwise, your best bet is to take it to a bike shop and try an ISO bottom bracket (gently) to see if it fits, or measure the threads ...

What are the times and costs involved in assembling a rideable bicycle from a salvaged frame?

This is the classic "how long is a piece of string" question, where almost any answer is valid. At one end you have a frame. And enough skills and time to assemble a bike, along with the ...

How to recognize a cheap from a quality steel frame

Single speed dirt jump specific frame for general riding

My short answer is no. A true dirt jump frame is going to be horrible for short XC riding and even worse for extended 2 to 3 hour rides. You won't be able to get the extension to pedal efficiently ...

Australia: I'd love to build a budget urban bike on a budget, where can I find parts like frames and wheels at prices comparable to bike shop builds?

I have done several builds with individual parts trying to beat the price of an assembled bike. It is difficult and time consuming. I was looking for fairly common parts, ten speed hubs, rim brakes, ...

Unless the frame is unusually valuable, it is almost never "worth it" to buy new major parts, such as a new rear wheel (with cluster, et al). A new rear wheel, once you've got the sprockets and tire ...

Shimano 105 RD-5501 on a six speed freewheel?
