open up more in the relaxed position?

R1 seems like it has low tolerances.

Am I doing it wrong?

Done all the pad spreading tricks, still have rubbing.

Even let a little fluid out.

chime in please.

PS. don't wanna call pergeum developers or whatever it's called cause I don't wanna.

They may need the tight tolerances to give you the lever feel and modulation they have. If they aren't adjusted properly or you add them to a flexy setup (large lightweight disc, weak quick release, flexy frame/fork) you'll get the rubbing.
As long as it's only a "sound" issue I wouldn't bother too much.

Shimano's ServoWave serves exactly this purpose. I seriously can't wait for the new XT brakes anymore I'm almost to the point of jumping on the XTR... I'm lucky that I can't ride because of the snow so I'm still holding back!!!

I suppose they'll unveil them at the Taipei bike show.

I would pay to have someone who knows

what they are doing, adjust the brakes for you.
I had a hub that had poor machining on the rotor tabs, which caused the rotor to be mis-alligned. Santa Cruz sold me their best component package, (nearly complete XTR package), except the hubs. They bought a railroad car allotment of a some of the worst hubs in the history of the world.
A new set of wheels fixed the problem.
OR, SHOULD I SAY THAT MY MECHANIC DIAGNOSED THE PROBLEM and I fixed it.
I spent a weekend trying to adjust my brakes and I just could not see the problem.
Cheers,

Kane

As mentioned, the close pad clearance allows a shorter dead stroke. This also allows using a higher leverage ratio between the lever/caliper which gives better modulation and higher braking forces.

As someone else asked, is the rotor warped or is it rubbing when you flex the frame/fork? With the right tools and some patience you should be able to get the rotor spot on.

This is the exact reason I decided to give the XTR trails w/servo wave a try instead of the R1s. I had the XT servo wave brakes and they were great, figure the XTR trails should be even better. I really wanted to give the R1s a try, but I'm not the type who wants to adjust brakes every ride/race or two. No one likes to hear their power being scrubbed off mid race by a rubbing rotor/pad... even if it's minimal.

Also, if formula wouldn't have shot themselves in the foot by putting only red on the US R1s I might've given them a try anyway. The combination of the tight tolerances and red (when the rest of my stuff is Ti/blue) pushed me from dropping the cash. Would've gone with the ones but they have an even worse color... gold. What the heck was formula thinking? At least go with a neutral color like black, or offer multiple.

They have tight pad clearance. It is the one thing in every single pro review I read that is a negative of these, and other, formula brakes.

I have R1s and one thing I have noticed to be true:

The instruction manual says after you have them set up to go through a few real "braking" motions. I find that this does make a difference. For instance, when I take my front wheel off and put it back on, there is always a tiny bit of rub if I just spin the wheel. But if I get on my bike and ride a few laps in the parking lot getting up to speed and braking, the rub goes away.

Also, what has already been mentioned above...if your hubs are crap or out-of-true, then you probably will never get them set up with out rub.

I love them...but I can see them not being for someone who prefers a true "set and forget" brake.

Hey BT,
Sorry to hear you are having trouble with your R1. If you dont want to call us, would you be OK with us calling you? If so, drop us a PM or email your phone number to [email protected] and we will give you a call.
There are a number of different things to check for which can increase pad retraction and minimize rotor rub.

We are happy to help...just give us a chance.

Cheers,

no rub problems or really any grumbles at all with a brand new set of R1's on my a9c build - even after switching to Swiss Stop disc25 brake pads which are thicker than regular Formula organic pads + Innolite rotors that are thicker than Formula steel rotors - i just made sure the calipers are centred correctly & the caliper bolts are properly tight

also i'm really careful to make sure the hubs are seated inplace & not angled when tightening up skewers & habitually pump the brakes just before a ride to help the calipers pistons centre if the bikes been inverted or not

we have Formula R1's on 3 bikes now - they are the best brakes we've used by far & massively out perform the Magnesium Marta's & SL Marta's with Goodridge hoses on our 2 "beater" bikes

^^^ if you can't set yours up for whatever reason contact Chris & Charlie :) ^^^

Chris,

I took my wheels off and installed the red pad spreader on the R1's, opened the bleed screw and let the excess fluid dribble out. I will try riding bike tomorrow to see if that helps. I own a set of oro puros and a set of the ones and my question is out of the three different sets, do any of them have a higher pad retraction than the other? The ones are the last generation, not the current.

thanks

Hey BT,
That is a good start just to ensure that your fluid level is correct and an overfilled system is not the cause of poor caliper piston retraction. If you are still having rubbing issues after that just let us know and we will be happy to give you a few other tips.

Cheers,

Chris
