Slack VS Steep Headset Angle Explained - How to Setup Scott Spark Headtube

Steeper, slacker - those words comes into place with Scott Spark models quite often. Yet, there is no super clear explanation on this in techbook, which makes it hard to understand. In this video you will find how to setup the headset cups with in-depth explanation.
00:00 - Headset Cups Explanation
00:48 - Two key 0.6 degrees cups Features
01:38 - 0.6 cups at steep angle installation
02:53 - 1st BB to fork measurement
03:26 - 0.6 cups at slack angle installation
03:54 - 2nd BB to fork measurement
04:40 - Neutral aka universal cups installation
05:46 - 3rd BB to fork measurement
06:00 - My setup preference
06:40 - Headset bearings, Ceramic Speed?
07:25 - Why Tom10Crafted channel
From visual examples, to actually measuring the distance, to give a clear understanding of the topic. Now if you consider which way to go - steeper is faster, yet slacker is significantly more comfortable for handling and cornering in trails. If you don't believe in me - try it yourself and chances are high enough you will be surprised by the feeling it gives.

    Which mode do you use? Is it STEEPER, SLACKER or I DON'T GIVE A DAMN one? :D Well, you should start giving a damn, until its not too late.

    Thank you so much for doing this and confirming the head tube angle. I was surprised how vague Scott was with the explanation. Most reviewers seem to think the steep is 67.2 and slack is 66.6. I suspected they were incorrect because of the inclusion of the neutral cups. I have even seen some reviewers, whom I won't name, only rotate the top cup and explain that will slacken it 0.6, and if you rotate the bottom cup in conjunction, it will slacken 1.2!

    Thanks! Same here - by writing few extra lines in the manual they could have get rid of any questions raised:) I very much hope that this is all true, but by having the measurements it would be possible to calculate the angles too! I have seen misinformation on very notable news websites, thus.. it just proves the fact that you have to be hungry to check few sources for facts confirmation:)

    Very informative content as usual. Thanks, Tom! Just when you think that scott can't make it any more complicated than it is comes the fact that not every cup will fit your body because the frame size is different. Well, I didn't expect that, but after a few minutes of considering, itt makes definitely sense.

  • @tom10crafted

    Thanks, Ivo, much appreciated! The sizing of cups is different because of head tube length, most likely. Different size frames has different head tube, and in order to maintain the same angles through all of them - thats why cups has to be different (S and M are the same, L and XL differs)

    Thanks a lot for that information. Superb. Ah, not sure if that's in this video: Rockshox damper in the fork. An ongoing problem. I had 3 times exchange of that part without lasting positive effect. It is a bleeding - problem. Seems that bleeding is not done very precisely at the service. I do bleeding by myself now approx. 3 times per year. A weak point of the bike. Yours Holger

    Hi, I have a few questions. If you can answer, I would appreciate it. Which headset angle do you like best? How many millimeters of spacing do you use in the headset? How many millimeters does the stem of your handlebar measure? Thank you!

    Hey, sure, happy to. I prefer slacker setup, as it gives more play in the corners and smoother singletracks experience. Thus, its -0.6 I use one single spacer, which results in around 2cm of height (~18mm or so). The cockpit stem is -20degrees, 10cm in length. The frame size is L and I am around 1.85m in height !

    Yes, BB goes down a tiny bit as well as head tube itself, yet its negligible difference which has no real-feel (like, you won't start pedal-strike everything immediately because of the change)

    Very much depends on conditions. You could feel that something is different, but not be able to tell whats exactly (not knowing something been done to it). Front wheel is a bit more in front, visually. As well as turning is different - and yeah, initially I thought it could be placebo, but eventually - going at similar speeds into corner is different story. Yeah, I hear it - its only 1 cm difference, haha! But every centimeter counts I guess - thats what she said :D
