Holding on to the cable you car feel the left lever pullind and releasing
due to lever settings. but it doesn't appear to be moving the front derailleur.
 
Any suggestions?
 

Somewhat confused to be honest, is the shifter moving the cable? But the
Derailleur isn?t moving?
 
As side note GRX is compatible with lots of other group-sets I have
GRX/Tiagra/Sora mix on the Gravel bike.

 
 
 
 
I got it working. The connection through the reel is pretty tricky. You
have to hold it in p;lace and then shift up a gear to lock in place. Same
on the other side. Then you pull the wire tight at the other end and
shift down and take out the slack. Then shift bach and take out the slack
again. These disk brake bikes are heavy, The complete build on this
superlight frame is still 20 lbs at the end.
 
 
 

GRX 10s is around the Tiagra groupset area ie middle range and light weight
isn?t perhaps its first priority the rear mech?s have a clutch, if your
riding on road can flick the switch to get lighter shifts.
 
With road bikes going for wider tyres, and aero bits and bobs, and
electronic gear weights have crept up, this said the uk hill climb bikes do
see bikes around the 6KG mark disks or not, do occasionally see bikes
getting sub 5KG but thats more folks having fun with weird and expensive
one of bits of kits than a bike that is race fit!

Always been that way.  Beryl Burton showed up at time trials
(and won more often than not for 25 years) with some scary
light machines 60 years ago.
 

Certainly now and has been for while weight hasn?t been TTer Focus but aero
hence silly hats and what not! The hill climbs absolutely go for it weight
or lack of it though with some spectacular if perhaps not particularly
functional machines!
 
Perhaps bikes at the time were heavy enough to make a difference?

 
 
 
 
All of these super-light bikes are fearsomely dangerous. Especially the
steel bikes which are .7 mm thick steel tubing custom made and on 48 cm
frames. I had a Look 495 that weighed just over 14 lbs without water and
flat kit. It was a 58 cm. It bounced around on the road so much that I
very quickly sold it off.
 

Thats not weight after all folks race bikes that weight up hills don’t seem
to get sub 6Kg bikes in the pointy end, but that’s more about the
durability and functionality of the kit, than being dangerous.

And well the Aethos which was or maybe still is sold which is 6KG or so and
seems to get good handling reviews.
