Can this be done? If so, who does one? Its an integrated headset and everything i have read elsewhere seems either contradictory of just out of date.

Not aware of any way to do this as it's the cup on anglesets etc. which provide the adjustment.

Your other options are offset shock bushings and / or a longer fork.. which will both slacken the seat-angle at the same time.

Which version of Hightower are you talking about?

Your other options are offset shock bushings and / or a longer fork.. which will both slacken the seat-angle at the same time.

These are also options. However offset bushes will actually steepen your STA, not slacken it. A Longer fork will slacken it (along with reduce reach, and increase BB height).

If the inset headset cups are bonded into the frame and you just drop the bearings in then no you can't fit one.

But, I have that fitting type on an old carbon anthem frame I'm building up as well. One bike shop said they thought the inset bearing cups 'should' knock out but they weren't 100% on that so I've left it for now!

Indeed.. not paying enough attention while typing and 'working from home'!

Its a 2018 model (the one before current)

Its got 150mm forks on it now so changing to 160mm isnt going to do much more. Im intrigued by the offset bushings though...

I retract my retraction.. offset bushings DO slacken your seat angle - source. This was why I haven't done it on my V1 Hightower.. the SA isn't great (compared to newer frames) and the 150mm fork with offset bushings would be too much for my preference.

Cheers frogstomp.

Ive now ordered 2 x offset bushings. So now should be quite slack once fitted:

Starting point HA = 67
With 150 Fork = 66.5
With 2 x Offset = 65.5

It rides great with the 150 fork but with the OBs this may turn the bike into a wandery, pedal striking, crap climbing, mess. But i can always remove one or both the OBs if that happens. Fingers crossed.

Hightower discussion is quite apt at moment with me.
Got mine sorted last couple of days.
I run a 150 fork. I have tried 160 looses its handling stability that is its massive plus point of the bike.
In low setting and offset bushings guessing it would be very low bb. ?

Ig you dont mind me asking. Why are you wanting a slacker HA ?

Its a fair question. The latest crop on "bang on trend" slacker bikes has just got me curious. I think the hightower handles amazingly TBH so i have zero complaints. I'm just wondering if i can make it even better for downhill stuff without buggering up its handling for everything else. If it starts feeling worse (which is suspect it might) its no big deal to swap the bushings back.

The fact you thought it was worse with 160 forks suggests the bushings may well make it crap on climbs.

The only geometry gripe I have is how far slack the st is.
I have a cc hightower and a alu nukeprook mega 2019 27.5
And there is not much in it climbing wise which I can only put down to the steeper st on the mega.

What stem are you set up with on hightower?
When I switched from 50 to 35 it made a fair difference. Didn't really notice much in regards to climbing but it puts your hands behind the front axle which really helps in corners and lifting the front end. Giving it a slacker feel to it. Granted shortening the reach a little but I just accept that whilst seated. Dont really want to send seat back on the slack st if you get me.
