Drop Bar Hydraulic Disk
 

I think that I'm going to change my flat bar bike over to a drop bar. There were no road shifters with hydraulic brakes until after I had put it together. (Or maybe they were so frightfully expensive we didn't move in the same spheres)

The problem appears to be that it is a 10 speed and the only hydraulic shifter I can find appear to be either 11 speed or Di2.

Were 10 speed hydraulic shifters even made?

I really would hate to have to change over to 11 speeds.

Next time you need a chain/cassette just go to 11:

The problem is with 11 speeds I have to also replace the rear and front derailleurs, rear cassette, the cranks and the chain.

I have tried using a 10 speed cassette that was actually an 11 with a missing cog and it is noisy as hell. You absolutely have to use an 11 speed chain. Then the front derailleur doesn't work properly.

Problem solved, assuming you're updating a Shimano equipped bike and not Campagnolo. And why do you want hydro discs? You were claiming they were dangerous and put you over the bars on your CX bike.

BTW, I updated my commuter to 11sp so I could get hydro discs for the long rainy season. I should have gone with the Tiagra 10sp and saved some dough.. Anyway, my FD is a 600EX museum piece, and it works fine. My crank is a 10sp, and it works fine. You don't need to update those things, unless you are switching over from Campy and there is some other issue.

I am sort of upgrading this bike so that my friend who intends to visit next year will have a bike that fits him. After realizing that it is already a Shimano set and I would have to change everything anyway to make it Campy, I bought the Potenza levers. My friend is so afraid of carbon fiber now that he won't even use CF LEVERS. So all will be replaced. And since he has been riding in Phoenix his climbing is gone. Here he was fast up the climbs.

I would like to put a Shimano bike together but I think that I'll save that for the Basso after I have it powder coated etc.

But since the medium arm Potenza derailleur can shift a 32 tooth cog, I no longer have to worry about putting him on a double ring.

Though his wife may require a bit of thought since my intentions are to rebuild my wife's Colnago Master 54 cm. Our visitor normally rides a 56 but since the Colnago has a long top tube I can probably get away with it. All I would have to do is have the rear triangle spread to 11 speed, get a set of Ultegra 11 speed levers, wheels (think I have a set that just needs a Shimano freehub) compact cranks and an 11-32 cassette. (A Colnago Master weighs in roughly at 2 1/2 tons)

My wife has been riding her Mercian and plainly there was never a better steel lugged bike built. You can even tell that pushing the bike while holding the saddle - you can steer that bike without a thought.

Andrew - I ordered that Potenza and it was not a hydraulic lever. It is something that is called "hydraulically optimized" and that has something to do with the rear derailleur and not the hydraulic disk brakes it appears.

It is made to use rim brakes or cable operated disks.

When I try to look up the Campy Hydraulic brake/mechanical shift levers they look the same. I wonder thy they are do damned secretive about how this stuff works. It appears to me that if you used Potenza rear derailleur, Shimano 11 speed 11-32 wheels and cassette and record 11 speed levers that you could have it all work together.

But the hydraulic brakes are a pain in the butt.

The Potenza levers work like cheap Shimnano levers. You can shift up the cassette 2 or 3 gears at a time but only down one at a time. This might not make a difference with an 11-32 though. Perhaps the ratios are so wide that you don't need to change more than one at a time. I remember that the 8-speeds were like that.

No, that is the correct one. You gave me a difference reference and until I read the entry in on the right side I didn't realize that they call the rear derailleur "hydraulically optimized." I suppose they use some sort of liquid shock absorber to keep the chain from jumping about on those very large ratio downshifts.

It is a lot cheaper from ProBikeKit too.

On your smartest day you can't even read. I have had several bikes with disk brakes but they are dangerous on CX bikes and hence on road bikes as well since they can lock the wheel up so easily. And the pads wear so rapidly that you have to check them constantly.

My friend is a Cat 3 racer. What are you? He's also a retired NCIS agent and carries a gun on himself 24 hours a day. That should cement your attitude because you are a loser and can't stand winners.

Tell us all what disk bikes you've ridden.

Campagnolo has always been weak on documentation and
terminology. In this case, 'HO' for a rear changer means the
upper pivot casting OD is minimized to clear a through-axle.

My pet peeves are using 'Record' for twenty or more
different products since 1960[1] and not marking the part
number on the part (something Shimano does rigorously).

That is really odd - what does the oversized axles have to do with "hydraulically optimized"?

I looked through the manual trying to discover how you would bleed the brakes and there wasn't even anything on how to thread the damn cables though the levers to replace them.

If the Potenza didn't meet my requirements and cost so little I would change over to Shimano.

Andrew - I ordered that Potenza and it was not a hydraulic lever. It is something that is called "hydraulically optimized" and that has something to do with the rear derailleur and not the hydraulic disk brakes it appears.

It is made to use rim brakes or cable operated disks.

No, that is the correct one. You gave me a difference reference and until I read the entry in on the right side I didn't realize that they call the rear derailleur "hydraulically optimized." I suppose they use some sort of liquid shock absorber to keep the chain from jumping about on those very large ratio downshifts.

It is a lot cheaper from ProBikeKit too.


Campagnolo has always been weak on documentation and
terminology. In this case, 'HO' for a rear changer means the
upper pivot casting OD is minimized to clear a through-axle.

My pet peeves are using 'Record' for twenty or more
different products since 1960[1] and not marking the part
number on the part (something Shimano does rigorously).

[1]Typical telephone call here begins, "I have a Record Whatzit"

"Which Record?"


That is really odd - what does the oversized axles have to do with "hydraulically optimized"?

I looked through the manual trying to discover how you would bleed the brakes and there wasn't even anything on how to thread the damn cables though the levers to replace them.

If the Potenza didn't meet my requirements and cost so little I would change over to Shimano.


That is really odd - what does the oversized axles have

The first version had an upper pivot casting which could
interfere with big fat through axles.

With friends like tom, you don't need enemies.

On your smartest day you can't even read.

And yet here I am, replying to you in plain english.

I have had several bikes with disk brakes but they are dangerous on
CX bikes and hence on road bikes as well since they can lock the
wheel up so easily.

Yes, WE know. You've written that repeatedly. How does that differ from "tommy won't ride discs because they're dangerous"

And the pads wear so rapidly that you have to check them constantly.

No, they don't, unless you're doing it wrong. But since you think "they are dangerous on CX bikes and hence on road bikes as well since they can lock the wheel up so easily", while the rest of the planet has no problem with them (including me), you're doing it wrong.


My friend is a Cat 3 racer. What are you?

"retied" cat 2 with 142 local wins over the past 30 years. I still race masters open 50+ in road and CX. I cal still pull out a 900 watt sprint at the end of a crit. you?

He's also a retired NCIS agent and carries a gun on himself 24 hours a
day. That should cement your attitude because you are a loser and
can't stand winners.

Are you suggesting that he'd pull his gun on me for speaking my mind? IT wouldn't surprise me he's your friend if that's the case. That's exactly the sort of thing you would pull.


Tell us all what disk bikes you've ridden.

My main CX is a Fort with discs (my pit bike is an old Bontrager Cx, handmade steel before they sold to Trek, not disc)). I also have two mountain bikes with discs - an old Independent Fabrications Custom Deluxe Ti, and my new favorite, a Cannondale Habit 3. I have a KHS tandem that I retrofitted to discs. I go out to Sedona to visit friends on a regular basis and rent a MTB, so have ridden disc bikes out there for the past 6 years.

You're out of your league here, tommy.

Seems like a reasonable guess. Shimano just uses a different RD design now with no need for a special model for through axles. Rather than a different model RD, it just launched its whole new gravel group -- which I think is ugly. https://www.cyclingnews.com/news/shi...pset-launched/ The clutch RD is nice, and if I were using monster tires, the revised chain line would be nice, too -- but I'm not.

The disk brakes can brake so violently that they pull the old style open bottom axles out of the fork slots. This was one of the things I was complaining about. On the work stand I was able to see this starting and could really tighten the quick releases. With the advent of aluminum quick releases I have even pulled the rear wheel out of the angular wheel slots by climbing hard. So now I am always careful to tighten the quick releases as tight as they will go without threatening to break them.

That's interesting, I didn't think there was any linkage between the introduction of disc brakes and through axles. I was under the impression that fat axles were introduced to simply make the bike stiffer (of course the cynic in me supposes it was also to drive customers to replace old systems), and the alleged 'safety' of through axles systems. If you look at what the UCI pro teams are riding this year, most have have disc brakes, but not all do, though all are mandated to the through axle design for the alleged safety aspect.

Seems like a reasonable guess. Shimano just uses a different RD
design now with no need for a special model for through axles.
Rather than a different model RD, it just launched its whole new
gravel group -- which I think is ugly.

The clutch RD is nice, and if I were using monster tires, the revised
chain line would be nice, too -- but I'm not.


I think several of the Shimano parts are ugly. The big knob on the STI
levers and the chunky crank spider arms that demand only Shimano rings
otherwise they look really crap. A mate bought a bike recently, covered
in Shimano stuff, and it has a brake cable to hydraulic converter on the
handlebars. Talk about ugly! Nothing wrong with cable actuated discs
on a road/gravel bike, especially with callipers that move both pads in
at once (e.g. TRP Spyre).

I find elegance in minimalist parts. Chunky doesn't do it for me on a
bicycle.

Cable to hydraulic can be done with elegance if that's what
he wants:

I don't think he's too concerned.

My limited experience with those is that they're unreliable (the master cylinder adjuster fails).

Tektro HyRd calipers do the same job with perhaps less elegance, but fewer problems.

If you have the levers that work right with them, which TRP won't tell you they
are. Not all shimano road levers pull enough cable to work them. AT
least one person makes replacment pulley mount dohickeys to change the
leverage ratio....
