it is best to do this with a headset installation tool. I don't have one, and they are not cheap. I typically use a long threaded rod with washers and bolts on either end to tighten the cups in place.

Typically, yes. But you are also buying better components than would traditionally come on complete bikes.

Joe Brave

Is it more expensive buying all parts separately than buying a whole bike? Customization has a price, I would guess.

Excellent guide. How much was your budget?

Could you make a more comprehensive guide on the rear hub and setting up the spokes?

Cool, going to try to re-build my bike that was left out in the rain one season. At least I'll know where to start. Fun fixer upper project.

This was really great. I'd love to see a mountain bike construction guide. Also use some videos if you are able. It makes some steps easier to understand than a pic.

Tobias Declercq

What kind of stem is this? Awesome bike and guide!

Tobias Declercq 9 months ago

Brian Stegall

for those who are wondering though... you can leave your fork uncut, however, you will need to add spacers on top of your stem to accomodate for the excess tube. this also will allow you to move your stem up and down within your stack height. however, in the case of bikes with a very short stearing tube, you will most likely want to cut the fork. otherwise, you will end up with a few inches of an impaling rod above your stem, which is fairly dangerous.

(author) last year

Brian Stegall

because I don't like that shit sticking up above my stem cap. if your bike is size properly you don't need excess wasted fork tube.

we can always make a guide out of converting your bike to bull horns haha. just saw the drops off and flip the shit over.

(author) last year

George Murray

I'd probably use bullhorns too. I never use the drops on my bike.

George Murray last year

Brian Stegall

good question! typical touring builds use drops. however, at the time I was pretty stoked on bullhorns and I had never seen a touring build with bull horns. basically just a preference choice. in hindsight, drops would have probably been a better choice for more hand positions, but 6k+ miles in and I still dig my bullhorns setup.
