GRX front derailleur.

Post by cyclintom
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?

Using much of the Beryl Burton equipment, here's an example
from when road racing bikes were 21lb.

Notice that that bike is a 52 sm or so. Small bikes wee surprisingly light since all of the xcomponents and wheels all wwighed the same.

Some of mu bikes (60 cm) are as heavy as 24 lbs and at my old average speed before 2024, I couldn't tell any real difference. Of course this was when hill roads were open. They are still mostly closed. California isn't repairing anything.

My BMC is 19 lbs without water of flat kit. My latest DeRosa Idol will be 20 lbs. My DeRosa Merak is 20 lbs, My Colnago Dream HP is 22 lbs. My Moser M82 is 21 lbs.

Beryl Burton was a Time Trial specialist would seem she got better as the
distances increased, she was faster over 12hrs than the men for good few
years, averaging 23mph! Weight wasn’t even then for the mainly though not
entirely TTs she did some road racing where weight would absolutely be more
of factor but riding at 25/23mph down a fairly flat TT course as most TT
are being able to get into the drops and hold it and ie aero and keep
pushing out the power matters.

Not the sort of racing that weight was particularly important.

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.

Well, that's correct but because the wire makes a 90 degree bend it backs inself out and you need left and right hand coordination and I am just getting over a stroke.

Why are you pulling the gear wire? Is that while riding?
Don't do that.

Or during installation? In that case, ensure the lever is
fully returned to low before securing the wire. Shouldn't
hear any clicks.
