I wonder how you tell what sort of hydraulic fluid is in this Avid setup. It could use either Shimano mineral oil or DOT 5.1 which needs replacing every year if that makes any sense. When was the last time you replaced your car brake fluid?

DOT 5.1. Do not substitute another fluid.

Any auto parts store or with a SRAM/Avid label.

By the way, Andrew, Mineral oil is a light petroleum based lubricant derived from petroleum. DOT 5.1 is largely solvents used to lighten the Polyglycols that are used in the fluid. Polyglycols are also derived from petroleum and are a very heavy lubricant. Polyglycols are used mostly in lubricating very high load gear trains and worm gears that carry very heavy loads. It isn't clear to me why you would use this lubricant cut 70% or more by solvents rather than a lighter lubricating oil like mineral oil one such a lightly loaded use such as a bicycle disk brake whose loading is almost nothing.. There are sometimes additives that are supposed to slow the evaporation of the solvents from the brake fluid.


Thank you for the cut-and-paste recitation. The bottom line is that your Avid/SRAM system is entirely incompatible with the Shimano system. Just look at the reservoir cap on the Avid brakes. It tells you exactly what you can use, and it is not mineral oil. From SRAM: "DOT 5.1 is the recommended fluid for SRAM hydraulic disc brakes. DO NOT use DOT 5 or mineral oil. These will destroy the brake’s seals and require replacement of the entire brake assembly."

This may be a case of that. Use DOT 5.1 and no other.

I don't know the chemistry of the seals and piston materials
and I'm pretty sure you don't either. I'm fairly confident
the designers and engineers do, or at least did when they
specified a particular fluid.


I do know that you have to replace this fluid supposedly every year (I doubt anyone does that) and that is because it is 70% solvents to cut down the very heavy lubrication grease. Mineral oil doesn't degrade ANY seals that can take those DOT solvents. Though I will follow your advice and use the cheaper brake fluid.

Six-bolt disc rotors are common as fleas. $20 for a Deore six-bolt of Amazonian. https://tinyurl.com/4nzbb92v What headset tool do you need? It's an integrated HS. Do need a crown seat setting tool? And are you switching to an Avid set up from Shimano? They're not cross-compatible. Avid/SRAM uses DOT fluid, and I'm not sure if the Shimano hose is happy with DOT fluid, and its ID may be incompatible with the Avid brakes as well. The levers definitely take different olives and nuts. Even if you could use the Shimano hose, you'd have to bob the ends, remove the barb, olive and nut, to get it through your frame -- unless it has giant openings. Go get some Avid/SRAM hoses.

BTW, the F55X is not a gravel bike. It is a CX bike. You have a slightly different version of the Redline Conquest you spent so long unloading.

-- Jay Beattie.

I suggest you actually learn to ride before you tell me what is a gravel and what is a CX bike since they handle totally different. You spend most of your time now being disagreeable for no other reason than you are a Democrat that is seeing your world crumble before your eyes and are loath to admit that you were told so, so many times that all you can do is attempt to refute it like a child. "Nuh uh".

WTF are you talking about? The Felt F55X is a CX bike. Google it. https://cdn.shopify.com/s/files/1/00...827 344467882

This is not an opinion. I own a CX bike and a gravel bike and am well aware of the differences. The F55X is not marketed as a gravel bike and is geometrically different from a gravel bike. It is a CX bike.

-- Jay Beattie.

Jay, they can call it anything they like. A cross bike uses a short wheelbase and a gravel bike a longer. The wheelbase on this thing is 43" A cross bike would be around 39".

By the way, I just looked up mineral oil as opposed to DOT 5.1 and it has better properties in all cases. The only difference appears to be that the DOT brake fluid doesn't absorb as much moisture which can damage the antilock braking systems on a car. But mineral oil is almost as good as they claim it to have the same properties. But DOT5.1 was specifically formulated to protect the ABS systems on a car. What ABS system do you have on your bike?

Actually DOT 5.1 is a glycol-based brake fluid and is compatible with
DOT 3 and DOT 4 systems and not compatible with DOT 5, Shimano, Magora
Royal or LHM+Mineral Oil.

Note: DOT 3 has a dry boiling point of 205 degrees (C), DOT 4, 230
degrees and DOT 5.1, 270 degrees.

The 32 tooth 10 speed cassette came in and I installed that yesterday as the hunchback. since the rear disk hydraulic line was mounted a rather long way it should fit on the 2 cm larger frameset without problem. The say with the front line. It is internal on this fork but was external on the other. So I will have to strip off the bead and cap on the lever end and stick it up from the bottom side. in order to lose the lease fluid and make it easier to bleed afterwards. It appears that flat bar gravel bikes are getting popular so this one should move a lot faster than the Emonda or Modone. The last guy to query about the Emonda must have been a monkey, after exchanges for three days he said th

at he
wouldn't fit the bike. He is three inches shorter than I am but claims his arms are 37" long. Maybe he is measuring from the middle of his back because from shoulder to fingertip my arms are 26".

The tires are 3 mm wider than I would like but there is more than plenty of room with these triangles. It is surprising how easy gravel tires roll on hard surfaces. But gravel bikes have lower gear ratios and the 11/42 high gear isn't going to rush anyone down the road. If I can get this together there is another Felt road bike that I will buy and build into a 10 speed Campy Record. The parts I have look brand new, though I will be looking for a compact two piece crank. That will require a compact front derailleur that will come from the Campy warehouse.

I was standing upright for the first half hour of this morning so I am recovering from that stained back if a lot more slowly than I would like.

I wonder how you tell what sort of hydraulic fluid is in this Avid setup. It could use either Shimano mineral oil or DOT 5.1 which needs replacing every year if that makes any sense. When was the last time you replaced your car brake fluid?

DOT 5.1. Do not substitute another fluid.

Any auto parts store or with a SRAM/Avid label.
By the way, Andrew, Mineral oil is a light petroleum based lubricant derived from petroleum. DOT 5.1 is largely solvents used to lighten the Polyglycols that are used in the fluid. Polyglycols are also derived from petroleum and are a very heavy lubricant. Polyglycols are used mostly in lubricating very high load gear trains and worm gears that carry very heavy loads. It isn't clear to me why you would use this lubricant cut 70% or more by solvents rather than a lighter lubricating oil like mineral oil one such a lightly loaded use such as a bicycle disk brake whose loading is almost nothing. There are sometimes additives that are supposed to slow the evaporation of the solvents from the brake fluid.
Thank you for the cut-and-paste recitation. The bottom line is that your Avid/SRAM system is entirely incompatible with the Shimano system. Just look at the reservoir cap on the Avid brakes. It tells you exactly what you can use, and it is not mineral oil. From SRAM: "DOT 5.1 is the recommended fluid for SRAM hydraulic disc brakes. DO NOT use DOT 5 or mineral oil. These will destroy the brake’s seals and require replacement of the entire brake assembly."

If you want to believe that is cut and paste it only shows you never took any chemistry at all. You make phony claims and then try to back them up with bluster.

By the way, I just looked up mineral oil as opposed to DOT 5.1 and it has better properties in all cases. The only difference appears to be that the DOT brake fluid doesn't absorb as much moisture which can damage the antilock braking systems on a car. But mineral oil is almost as good as they claim it to have the same properties. But DOT5.1 was specifically formulated to protect the ABS systems on a car. What ABS system do you have on your bike?


We saw failures with the Italian made Formula disc system on
Santanas when owners made that assumption and used not-DOT
5.1 fluids in them.

Your average human would look at, taste and smell GM Dextron
and Ford Type F ATF and assume they're pretty much the same
thing. They are pretty much the same thing. But they differ
enough to wreck a slushbox of the other type.

Six-bolt disc rotors are common as fleas. $20 for a Deore six-bolt of Amazonian. https://tinyurl.com/4nzbb92v What headset tool do you need? It's an integrated HS. Do need a crown seat setting tool? And are you switching to an Avid set up from Shimano? They're not cross-compatible. Avid/SRAM uses DOT fluid, and I'm not sure if the Shimano hose is happy with DOT fluid, and its ID may be incompatible with the Avid brakes as well. The levers definitely take different olives and nuts. Even if you could use the Shimano hose, you'd have to bob the ends, remove the barb, olive and nut, to get it through your frame -- unless it has giant openings. Go get some Avid/SRAM hoses.

BTW, the F55X is not a gravel bike. It is a CX bike. You have a slightly different version of the Redline Conquest you spent so long unloading..

-- Jay Beattie.
I suggest you actually learn to ride before you tell me what is a gravel and what is a CX bike since they handle totally different. You spend most of your time now being disagreeable for no other reason than you are a Democrat that is seeing your world crumble before your eyes and are loath to admit that you were told so, so many times that all you can do is attempt to refute it like a child. "Nuh uh".

WTF are you talking about? The Felt F55X is a CX bike. Google it. https://cdn.shopify.com/s/files/1/00...827 344467882

This is not an opinion. I own a CX bike and a gravel bike and am well aware of the differences. The F55X is not marketed as a gravel bike and is geometrically different from a gravel bike. It is a CX bike.

-- Jay Beattie.

Jay, they can call it anything they like. A cross bike uses a short wheelbase and a gravel bike a longer. The wheelbase on this thing is 43" A cross bike would be around 39".


Well, sure, they could call it a touring bike, or a road racing bike, but that would be a lie -- and it would undercut the whole idea of building a CX bike. No?

I don't know where the F55X falls in the CX design world, which seems to oscillate back and forth in terms of steering geometry and chain stay length, but it will certainly have a lower stack height, higher BB and less features for use on the road, although some entry level CX bikes will have fender mounts. My CAADX does. The CAADX also has a dreadful, slack HT with lots of fork offset for a really heavy feeling front end on the road. I much prefer the more roadie feel of my Norco Search gravel bike.

The bottom line is that if you're building this for resale, you're looking at a tougher resale than just a real gravel bike with drop bars. You're building a coffee shop racer with flat bars and big tires. Maybe that sells in the Bay Area. Avid hydros also have a bad reputation, or they did. Maybe it has improved.

And depending on what you're going to try to sell if for, you're up again a really great bargain gravel bike -- the Trek Checkpoint ALR. The CF version was Velo News' bicycle of the year. https://www.velonews.com/gear/gravel...eckpoint-sl-5/ I'd get one of those, but I think I've gotten my limit of pro-deals from Trek.

Plus, I already have my Norco Search, which I got on sale from Western Bikeworks for $1500. This one: https://www.norco.com/bike-archives/2017/search-c-105/ With my custom-applied ho-made frame guards: https://photos.app.goo.gl/PhLwf6MRK8TfPAJYA It's a fun bike.

Nope Jay, you obviously called it wrong. I mean, after all, Felt
calls it a "Cyclocross" and you call it a "Cyclocross" but Tommy calls
it a "Gravel Bike", thus logically it must be a gravel bike.
