On one bike I have a GRX 810 FD with an Ultegra crankset and no issues.
The GRX FD has a wider range and can be easily adjusted.
I have an Ultegra FD with a GRX 600 crankset on anorher bike and it works more than reasonably well.
The only issue is that the chain slightly touches the FD while on the smallest sprockets and I couldn't get rid of it yet.

Now you make me really want to get one... For your other bike, was the grx fd clamped on or brazed?

I'm not sure to understand what you mean.
I replaced an Ultegra crankset with a GRX 600, I didn't add any spacer and I don't see any play.
Beside, road cranks and "Gravel" ones are made for the same BB size.

Interesting, I guess the chain line difference is just cassette spacing then?

2.5mm of spacers to compensate for chainline and the height adjustment is up to your frame

I'm not the master in groupset, but I though the spindle lengths were different between them?

Hi, it's been a long time, but do you still like your xpresso pedals from F1z bike shop?

Here's my best of :
Elita one seatpost and saddles
Firespider handlebars
Uno stems too
Balugoe $24 86g bare carbon saddles(but tend to crack after a while)
xpresso pedals Ti, 160g F1Z bike shop
handlebar bags, for long rides(Loving Outdoor Store)
Darevie shorts
SK Cycle carbon seatpost clamp
Alpha cycling pink break pads
Nuga store tubeless syringe
Onirii M2 brakes
Balashov Electric Cooking Machine 1.7L, to wax chains
Magene Radar L508



I liked them but not anymore:
Gaciron lights, great but their straps are crap, I've lost them all

I really wish they would make a grx version... Or does anyone know how to make grx fd work with 105 crankset?

I've been running the Juin Tech GT-P 4 piston hybrid calipers for about 4 years now.   I chose these because of great reviews, and that I could use regular STI brake shift levers on my gravel bike, and not have to pay out big $$$ for indexed hydraulic levers.
4 years later I look back, and have not really been happy with them overall.

1.  For general riding on paved roads and some gravel roads with limited descending they worked great.
2.  On long steep or technical descents I have had many problems with them.
     -  Calipers overheating, and the mineral oil expanding and locking the pads onto the rotors.
     -  Brake fade on long descents.
     -  Almost continuously having to adjust the knob on the caliber because if too loose, then the brake lever pulls too far, or if too tight, often drags the pads causing overheating.
     -  rapid pad wear. 
3.  In about 8K mikes, I have replaced pads 4 times.
4.  About 2 weeks ago, the front caliper was working, then all the sudden it no longer stopped me. No matter how hard I pulled on the brakes.  Swapped to another GT-P caliper.  Cleaned the one I took off, opened up the bleed ports, and had to add some mineral oil.   No signs of leaking oil anywhere on the caliper.  I am guessing that a bubble must have developed and kept the pistons from pushing on the pads to rotor.   This issue almost caused me to crash on a sharp left hand corner.  Thank goodness the rear was still working.

I migrated away from these hybrid Juin Tech hybrid calipers to full hydraulic on my 29er hardtail that is set up as a gravel grinder.  Once I put on full hydraulic brakes, I realized how poorly the Juin Tech really perform.   

I Plan to swap out the Juin Tech's for full hydraulic this winter on my Gravel bike. 

I have become addicted the the ZTTO Carbon "H" bars.  I already have them on 3 of my bikes.  Even though they have less of a drop than regular flared gravel bars or road drop bars, I find them to work really well and they allow you to run mtn. bike hydraulic brake levers and the Wheel Top EDS derailleur.

Agreed. I have Juin Tech GT-F 4 and don't think they're worth they money remotely, and ultimately got a new fully hydraulic groupset. Do note that I've a heavy guy (180lbs) living in a hilly area, so it may be fine for you depending on where you live/how much you weight etc. For anyone who gets told that they're as good as hydraulic: they're not even remotely close, unless you bleed your hydraulic groupset really really badly.

Wow that looks quite dangerous! I'm curious to see what will happen.
