I'd like to test one out on a Trek 8000 with 22mm mount. Let me know when to send the money.

Can someone measure the horizontal distance from rear drop out to the most rearward 22mm mount hole? I'd like to confirm this mount design will work for a 2001 Trek 8000, measures 56mm.

It should be identical, as they were both using the Hayes "standard."
That said, nothing is ever standard in the bike industry. I don't have a frame with that mount so can't measure mine, but here's a CAD model from one of the engineers. The dx value is the perpendicular distance, which is what I assume you were trying to measure.

Wonderful. Thank you. 
 

I found a local fabricator to make one for $60 or two for $80, aluminum. 
 

Can you please share design to accelerate my project?

I don't have any design-Eric has one but he's been selling the adapters, not his design.
I'd also be a bit concerned about any machinist that's quoting you pricing for this if you haven't shown them a concrete design.

Agree. I sent him a 3D drawing from a similar thread on MTBR. 
 

The design Eric has differs a bit from the one on MTBR and it is the offset (distance from axle center) of the flat mount holes in the adapter. At least it appears that way from drawings.

These have been shown to fit on Rocket-88, hardtail Homegrown's and Independent Fabrications.  I have a question for the buyers of this adapter.  Has anybody tried to fit one on a Sweet Spot frame?  Mr. Pivotless himself is asking me and I don't have an answer to give him.  If a previous buyer can chime in that would be great.  Thanks for your help!!

This is why I was asking about the measurement from center of axle. My rough caliper measurement had something 55-57mm. Some shared the drawing that the Hayes standard is based off a 55mm span from the center axle to the first 22mm mounting hole. I think that if the frame's mounting hole is 55ish mm from the axle center it will work. 
 

I will test mine on a 2001 Trek 8000 very shortly.

It was funny seeing your drawings for the Adroit adapter.  When I first started the development of this adapter it was for a gravel bike using a 140mm rotor because that was the standard.  I discovered that I was not able to mount the caliper and use a 140mm rotor *on Homegrown frames* due to frame interference with the caliper.  I seriously doubt the "Adroit" frame was designed for 180mm rotors, so the design you showed would not work for 160mm rotors at all.

The white concept on the right was my atempt to fit a 140mm rotor but the caliper had clearance issues.  The grey concept on the left was required for a 160mm rotor with no clearance issues.

You can see the Homegrown/Schwinn measurement for the Hayes mount is 55mm~ish from the axle to the center of the first bolt hole.  You purchased the proper adapter to run a 160mm rotor by my calculations on an Adroit frame.

Let me and the Bonus Tomato community know how your fit works.  Thanks,

Look at you, showing off your 3D printing and digital calipers.

Some of us have to remember how to use our Granddad's vernier calipers every time we go to use them...

Installed and working. I had to file off some powder coat to get the front of the adapter to lay flat. I also may need to file the front mounting slot to allow better alignment/centering of the  caliper. The front of the caliper needs to be farther outboard.

Adroit Rider, I have found that XTR caliper mounting bolts have a smaller diameter head then what you are using.  The smaller 4mm socket head allows for more side-to-side alignment ability than those monster bolts you're using.

Thank you. That is much easier than filing stainless steel.

I considered making an adapter like this when flat mount was first introduced, but I did not have the Hayes 22mm specifications. A less expensive version of this adapter could be manufactured by laser or waterjet cutting. I can get a quote if anyone is interested.

OK everybody......I have 4 more adapters coming, but ONLY 2 are available.  The adapters are not in my hands yet, but will be early next week.  These will all be the Stainless Steel version which is smoother and slightly lighter than the nickle plated steel/bronze.  Price went up this year so I need to pass that on, meaning $60 each (includes shipping to USA).  If these sell out, I'll get another batch ordered again.  These have been more popular than I imagined.  There are now about 16 in the world floating around making 90's bikes cool again   Smile

Hello, 

I am very interested in this item. My hesitation is it would be used on a Homegrown Sweet Spot frame. The angle of the seat stays is much less vertical (allowing VERY little space). It appears as though one member with a Sweet Spot purchased one of the adapters. I am hoping he will please confirm that it worked for him... Or if any body else can confirm that it will work with a Sweet Spot frame I would really appreciate it.

Cheers,

             Seoane

I can't confirm if these will work with the Sweet Spot frame.  I too would like to hear back from anyone who has tried it.

Hey, just registered to say I am interested in one of these mounts, but also have some questions if you don't mind.

I came across this thread when looking for adapting Hayes.

I have a '99 Gary Fisher that has Hayes mounts, but it is a 17.5" frame. The a2z adapter does not fit since the rear triangle is so small, so I am looking to get something smaller, and this looks like it would work.

However, it looks like your adapter does 22mm Hayes to IS, but the IS mounts are horizontal, whereas the a2z was putting the IS mounts vertical - so with that one, my hope was to then convert IS to Post Mount and go on my merry way.

With this adapter, I could run a flat mount rear caliper then?

Thanks! If I am correct in my assumption, I'd love to buy one!

In summary, the A2Z adapter will require you to use a Front IS caliper in the rear for a 160mm rotor.  It rarely has clearance for the post mount adapter style calipers.

My adapter is used to only mount flat road style calipers that are popular with gravel and CX bikes.  There are various brands of these road calipers, and you must use the proper branded lever to make it all work.  I like Shimano so I use Shimano MTB levers with Shimano calipers.  Message me if you want to buy one.

Hello Eric

This is genius. I can finally stop constantly trying to resuscitate the old hayes 22mm caliper on my spooky pitboss.

Do you have an adapter that you would be willing to ship to the UK?

Thanks

Rich

I am using the Shimano flat brakes in your pictures - however the bleed nipple won't clear the seat stay.  Am I doing something wrong?  U have plenty of clearance.  I'm using these on 2 2000 Homegrowns both 19s

My only guess is that you did not remove the Shimano adapter piece that came on the caliper?  You need to use the screws that come with the stock adapter and caliper, but use my adapter directly with the caliper.  I am also assuming you are not talking about a Sweet Spot frame?  I have not have confirmation on fitment to those frames yet.

Please post up a picture if possible.

I will confirm tonight what P/N my Shimano caliper is, and post tomorrow.  At quick glance it looks like the model I'm using has a lower bleed nipple then your 105.  I apologize for causing you to go through multiple caliper options.  I had no idea Shimano's different models would vary so much.

Fyi... ultegra 8070 and 105s (7070) don't work.  Frames are too large and the bleed valves won't clear on circa 2000 Homegrowns.  Shimano stuff is in short supply as the factory in Malaysia been closed due to covid.
