I am going to convert my drop bar gravel bike to a flat bar bike. It is a 105 11 speed with 105 hydraulic brakes. I have, what I believe to be, the correct shifters for a flat bar with Shimano Shift levers RS700 dbl 11 sp Flat Bar. What I am having a problem with is the brake levers. What lever set would be compatible with the 105 calipers? Thank you in advance.

Find the model and part number for your brakes. It's on them somewhere. Probably the backside or down on the mount. Then go to Page C-499 of this document. If your model numbers are out of production then you might have to go to the archives which is a link in the top right of the document.

Your brake PN should be in the last column. The shift levers will be in the second column. Make sure there is a line connecting the box with your brake model to the hoses and then to the levers.

If you are wanting something other than Shimano, someone else will have to say. Microshift usually has stuff that works.

Thank you for this. I will look for the part numbers and find the necessary parts. Is Microshift a decent quality piece? I have no experience with that brand.
My biggest concern is that the brake levers will retract the pistons.
Thanks again, Frank.

https://www.microshift.com/ has been around awhile. They seem to have a decent enough reputation. And for very old Shimano stuff that you can't fix or find, Microshift will have compatible stuff that will usually work with the other remaining Shimano components.

But I've never had the occasion to use them for anything that I can remember. Seems they make some stuff that is fairly higher end too but inexpensive. If I had to, I might trust them more than any of the other inexpensive options offered on Amazon or AliExpress.

I am having a problem trying to confirm what flat bar brake lever will work with the 105 calipers. I have found Shimano BL-M8000 Deore XT Brake Levers but can't find any information about if they will work with my series 7000 105 calipers.
Any help would be very much appreciated. I tried to find this on the charts suggested earlier but I am not familiar enough to be confident in what I think I am reading.
Thanks in advance, Frank.

I'm thinking it's not. The hose compatible with each are not the same. I didn't realize what I was showing you was only listing a sub-brake lever which is intended for using in addition to the STI on drop bars bikes.

Certainly someone familiar with the subject will chime in soon. Otherwise it is the blind leading the blind. <grin>

Until someone who'se done it chimes in (and corrects me if I'm wrong):

I haven't tried, but I'd expect Shimano BL-RS600 to work.

Safest bet is to check with a local bike shop (supporting it by purchasing there, and confirming it's compatible).

I recently bought an 8-speed MicroShift trigger-shifter to replace a Shimano unit controlling a Nexus 8-speed hub. It works very well, but the red indicator needle jumps all over the place as if it's loose or disconnected inside the housing. It's not a big deal, but it is a bit disappointing. I have no other experience with MicroShift products.
