I took the Colnago out`for an easy flat ride.things requiring correction:
1. the handlebar is pulling that carbon business of needing more torque
than reonmended. If you put hard brakes on the rotate.
2. the brakes make noise under light braking.
3. there is something wrong with the freehub. during coasting there's
some kickback on the chain. This might be somthing as simple as a loose cassette dur that appeared to be ok..
The Colnago is very fast handling. Without any doubt a racing bike. After yesterdayrCOs ride I expected a slow ride but today was 11.4.

What is the recommended torque setting I assume you do have torque wrench? Can?t say I?ve noticed carbon loosening, the seat post hasn?t moved, the Revolt is carbon frameset with a Carbon post, the bottle cage did rattle loose but new bike and all that.
2. the brakes make noise under light braking.
Pad postion ie on the rim properly, I?m assuming it?s rim braked if disk potential oil contamination as that is definitely disks weak point.

I could be wrong but I?d assume that more likely to be the free hub as if
the drivechain is static even if it?s not correct it?s the free hub that?s well freewheeling.

It is a unapologetically a race bike so will have a low stack and so on.

Uh, Roger, the handlebars are not a seat posrt.This bike is made from
Ghibl tubing anyway and the seat post has very limited up and down range.

Seat posts are generally supported over a longer distance and that increases the friction loading making them more difficult to slip. Handlebars on the other hand have a 3 cm stem width and a holding area dependent upon the design of the stem. So slipping handlebars are much more commen and I've seen aluminum handlebars slip and carried a multitool to lend aid to people with that problem. While it is hardly common carbon fiber bars are more flexible and have that problem often enough that it is hardly unknown.

Indeed a seat post will have a greater load as of the 3 contact points the saddle takes the largest load, on my Carbon bike and frame/seat post being
a Gravel bike it has more of its weight back than your Colnago which has a more forward position.
Add that I?m apparently heavier, and yet the seat post clamp hasn?t slipped or needed adjustments with a carbon to carbon set up.
Plenty of carbon bikes in the club aka real word plus aluminium and steel
and I promise bars rotating isn?t a thing, this is you need to check the torque values etc.

I fixed it on the Colnago by using a Specialized stem with mote contact area. It worked fine on today's ride up Cull Canyon (totals of 1,500 feet of climbing) though the freehub problem is still there. I will put the wheels in a shop since it may be a bent axle.
Nice thing about 11 speed is that the spacing is the same for Campagnolo, Shimano and SRAM. So I have three spare sets of wheels that will work.
That's highly unlikely. Bent axles on modern cassette hubs,It seems that it mkight be the srew fitting on the outside of the off-side axle. It might be overly tightened and there is some corrosion where the fitting rubs against the hub.The axle will have to be removed and the whole thing flushed out. When you freewheel it, the axle tries to turn. Outside of the dropouts, freewheeling it allows the axle to turn so you can't feel the drag.
even aluminum axles, are virtually unknown.
