It's called the Klamper, and makes me want a disc road frame.

[eBAUMANN]

i am definitely building a SSCX disc frame for these next season, complete paul gruppo, just cause.

You are short drop bar levers. Trp would be nice though.

I think a ss mtb with full Paul would be hot.

Is there any info at all about these??
Release date, price? Google has little more than this same pic

[thirdgenbird]

So far, they have just said see them at interbike. I'm guessing details will follow. They only said road/cx, but i would be surprised if a MTB version doesn't follow.

that sounds dreamy.

Avid BB7 clone? It looks like only one pad moves.

[Admiral Ackbar]

yeah i sort of would have expected them to do something like the trp brakes where both pads compress a la hydro brakes.

curious to hear how they perform tho

[vqdriver]

I really want to want these but dunno how excited I'll be if they're just CNCd bb7s

[shovelhd]

Those look sweet. What does the knob do?

If like BB7, moves the fixed pad over for adjustment. If mechanical, I think they could have figured out a 2 arm type that moves both pads. But..

[FlashUNC]

Paul just teased them on their FB page without much additional info as well.

[R3awak3n]

one thing is for sure, they look easier to adjust than BB7s with their tiny hard to turn dials.

[josephr]

meh....another over-priced "me too" item for the style conscious.

Yeah, why pay premium for well paid US based jobs?

To say nothing for their consistently excellent parts.

[Mark McM]

Too small. Not enough heat absorption/dissipation. Well, that is unless they are designed to continue to work when they are red hot.

who says that sscx bikes need to be drop bar? plenty of guys (including Adam Craig and Craig Ethridge) have raced sscx on flat bar cx rigs.

Not me, I only stated Paul didn't make drop levers.

I thought of this when I made the post but assumed he wanted drop bars with the majority of cross guys. If he wants flat bars, I'm all for it. I would just rather build the 650b mtb if I went on a Paul spree.

[bshell]

Meant to say I'd try 'em/buy 'em.

I installed new pads on my Avid bb7s last night on both MTB and SSMTB and those little dials are a tremendous pain in the ass to get a grip on to turn. Not a smooth dial in any way. The larger, inboard one especially.

Otherwise, they are my favorite brake!

Used these for @ 12 years and they have never let me down.

As far as heat dissipation (correct me if I'm wrong), that's the rotor's job. There is no brake fluid to boil in a mechanical caliper.

[gdw]

BB7s are great brakes if you know how to set them up and the Paul's will be a popular alternative if they perform as well or better. Hopefully they'll include a torx/allen bolt to the inner dial, spoke side, on the production model to make adjustment easier.

[Mark McM]

The most common overheating issue with BB7 brakes is that the plastic adjusting knobs melt.

Being a mechanism with close fitting moving parts, differing rates of thermal expansion have to be considered in the design of a mechanical caliper. If not designed properly, the mechanism could jam when overheated. The BB7 probably benefits from the ball bearing mechanism, which is probably tolerant of some mis-match in thermal expansion. I hope the designers of the Paul brake have also accounted for this.

[sworcester]

Doesn't this show a left and right side of the caliper? Then doesn't it show two dials (knobs?)

Yes, it shows two dials. But the Avid BB7 also has two dials (for adjusting each pad), but only one pad actually moves.

Bastards!

I think someone (here on this forum) should take it upon themselves to fabricate dials to replace the red crap ones on BB7s. I know they are just average brakes, but I still think they work fairly well all things considered. If they had a nice faceted alloy silver dial, they would instantly look so much nicer!

I, for one, would buy a few of these. Anyone? Anyone?

[saab2000]

Don't know anything about these but I'm pretty happy with my TRP Spyres, particularly with the installation of compressionless cable housing. That made a HUGE difference and I bet it would with any mechanical brake.

I'm waiting for the mechanically shifted, hydraulic brake shifters from Shimano. That will be interesting.

These look cool but I'm curious how they advance the technology. The Spyres seem to be the best mechanical because they compress upon the rotor from both sides.

[bshell]

Not sure about the construction of the current Avid BB7 but there is no way you could melt the adjustment knobs from my era by heavy braking.

Can't comment on tandems either but for a solo rider ...nah. Have any of you *actually* had this happen?

Yes, have had this happen on a tandem (rider+bike weight about 330lbs) . Situation was a 90F day, descending 10-15% switchbacks with automobile traffic when everything just came to a stop for about 8 minutes due to road construction. When we got home, i found the inner adjustment knob had melted (outer knob was fine), probably due to the loss of convection cooling when we were stopped with all the heat built up in the rotor and caliper from braking due to traffic. Brake was gritty sounding but functional. Fortunately, Avid sells the knob bits and they're easy to replace.

[tigoat]

Yeah CTE mismatch is usually a major problem with a mechanical assembly that involves heat. Ideally, all the components in an assembly are made of a similar material to minimize various thermal expansion rates. You will have stress build up on an assembly just sitting around by heating and cooling it let alone having it functioning. With that said, thermal expansion and heat sinking are two different things and must be addressed separately. As for the BB7s...

[tigoat]

Yeah TRP Spyres are a major improvement over BB7s due to the dual actuation system. They might have a patent for this design so I am not sure if others can copy it. The picture above shows a single arm so it will more than likely similar to the BB7 system, which is no long good now that we have TRP Spyres.

At a 480 a pair you may as well buy hydro levers and skip the half assing

And it sounds like that's without discs or levers so you are over $600 with the matching paul levers. Compared to what? $250 for slx brakes?

I love Paul suff but that's too high for me.

[gdw]

They'll sell. Folks spend $146 for a single center pull or $137.50 for a v brake so $240 for a cnc'ed BB7 isn't out of line. That said, I'll pass especially after purchasing two wheels worth of new Shimano XT disks and rotors for $214.

[thirdgenbird]

Oh, I know they will sell. It just won't be to me. I would spend $100 on a nice v brake before I spend $250 on a single piston mechanical disc.

$240 per wheel for this caliper??? Rotors included I hope?..seems like a lot for warmed over BB7, US made mechanical discs..

For that $, SLX/XT/XTR wet brakes are a bargain. $180 per end for XTR

[thirdgenbird]

Paul's Facebook said bring your own disc.

[deluxerider]

Will they come in a Rasta color scheme?
