11s GRX gear lever not engaging

Postby warthog1 » Sun Jun 23, 2024 4:19 pm

Went out on the Revolt today after having a new bb put in at the shop where I bought it.
All good on the bb front.
It was in the small ring as I always leave my bikes. Shifted up into the big ring as normal. Wouldn't go back into the small ring though. The shift lever just seemed like it wouldn't engage. Full range of movement with no click and no resistance. It has done that once previously but started shifting again after briefly refusing to.
Anyway got home and after a shower had a look with my glasses on. The cable was intact with no fraying. The spings and guts of the shifter were a bit of a mess with what looked like mud. I had given it a spray with silicone lube prior to putting my glasses on and it was now a congealed mess of dirt and silicone spray.
Gave it a squirt with the garden hose on the jet setting and it is clean again and shifting the front rings up and down nicely. :)
Have put it up on the rack to dry. I plan to give it another squirt with silicone spray tomorrow when dry. Does that sound like the right stuff to spray it with?
I also have white lithium grease in a spray can, and motorex 2000 in a spray can. I figure both of them are going to collect dust worse than silicone spray though? Given it is a gravel bike there is going to be dust.

Knew I had that motorex 2000 stuff for some reason. :idea: :)
This came up on a google search;

I use a light grease from Motorex which they label 2000 Spray. It's light enough to soften old dry shifter grease and not gum stuff up, but sticky enough to stay put pretty well.
Just unsure it is the correct stuff to use on a gravel bike where dust is an issue?

I wonder if PTFE spray lube is a good idea? Being dry you'd assume dirt is less likely to stick to it. Just more frequent applications perhaps?

Hmm a bit more investigation today. Going to go back to my aluminium bars as I have overtightened the hoods and damaged the carbon ones :roll:
There is a cover on the GRX levers you can remove. So I did that. Not pretty.

Flushed them out with a whole heap of WD40. Got some of that ptfe spray to try. Will do that once the bars are swapped over.
Gravel needs more maintenance than this dodgy roadie is accustomed to.

Take the lever off and soak it in some rust remover, I've never seen that before.

Not rust, dirt. ;)
Sprayed half a can of wd40 into it and all good. Sprayed them with ptfe spray. Have it all back together with my aluminium bars back on and new bar tape. Shifting well now. :)

Maybe that’s one more reason to go 1x on gravel bikes :mrgreen:

That is the R hand shifter. So rear gears anyway. Bigger gaps and less range with 1×. Not seeing the point personally and it gets used on the road at times too.

Di2 is the fix. They are pretty well sealed systems

$$$ though.
That is 21300k with an obvious lack of maintenance. :oops:
Need to lift my game. It needs new steerer bearings also by the feel of it. Got to buy some tools to bleed and manage shimano disc brakes.

I did this recently. Learned a lot on the job. A bleed kit and a barb setting tool are all you need.
No need to spend $100 on a tool, either: https://www.aliexpress.com/item/1005006172205570.html

Thanks for the reminder to peel back the hoods of the most used bikes and give them a once over!

Thanks FG :)
Ordered that tool.
What bleed kit do you recommend?

The one I got was the generic yellow plastic kit with a few blocks, syringe, some tubing and a few odds and ends. Much like this one:
https://www.pushys.com.au/ezmtb-lite-un ... d-kit.html

Worth checking which version of the threaded port your levers have. I had to make an adapter becuase Shimano have changed the thread size between models and now make an adapter.
Refer https://bicycles.net.au/forums/viewtopi ... 5#p1611554 and a few subsequent posts.

Shimano part number Y0C698050 is the adapter between the different threads.

Not sure how drop levers differ, but I have 2 sets of these.
One for mineral oil, most shimano stuff, and another for synthetic dot fluid so they don't cross contaminate.
