My front brake is what I feel a good brake. It's a dura-ace and I've put alot of work into it to get the weight down. My question is which brake can I put on the back that is light. I don't need much stopping power back there and a dura-ace isn't very light. 8) :roll: 8)

FRM has a nice one http://www.frmbike.com/componenti/freno ... -road.html Cat bikes has one that I havnt yet had a chance to play with, and there's the carbon one that was on the Stork at Eurobike...
One of my customers has a pair of DA Ti single pivots, ex-pro issue, Ti, bolts, spring and extra machining. Wont part with them though...

I bought the Cane Creek calipers which look the same as the FRM. They were on sale at Cambria Bicycle Outfitters for about $180. I bought one through my LBS and it weighed 123 gms. I am now optimizing it. I like saying optimizing. :roll:

Just got back from weighing it. It came in at 98 grams after taking some parts off and grinding/drilling others. That includes brakepads and all mounting hardware.

Cyco, I would like to but I don't have a digital camera and don't know of someone who has one or will lend one. To describe it would be difficult. The best I can do for now is post before and after weights, and encourage others to try. I can tell you to look at every part on the component to see if it is really needed as some are there just for quick easy assembly. Use your judgement to see if the part is overbuilt because some people abuse them. If you add up all the parts that could be lighter the overall weight is alot. It's like counting calories when on a diet. If you stop and measure all the little snacks and such, that's where your putting on weight. I'll try to find a digital camera. Maybe there is a bike person around that has one. By the way I can't use popawheelie to post so I just use popawheelie2.

So, anybody have any more details about FRM brakes? How light are they? Any flaws? They were suggested in reply to a request for a caliper that was light without necessarily being very good. Are they any good? FRM makes a carbon crankset. Can anyone relate any personal experience or info? Can they be interchanged with Campy 10s? How about the rest of their stuff?

I am currently running a FRM H-Set and S-Post in my track bike and neither has needed to be touched since instalation (2.5 years). I've also built several pairs of wheels with their hubs and they are still being ridden.

As to the brakes and BB, I haven't used them, so I can make no comments about these. The only part I have chosen not to use was the stem - I found that a touch flexy for track use (See biggest weight weenie thread), but plenty of others have no issues with then.

I went to the frm site and the single pivot brakes look alot like the cane creek 200sl brakes. They listed distributers in different counries with e-mail addresses. As far as I know www.cambriabike.com still has a set of cane creek 200 sl brakes for $180. The rear brake I bought came in at 123 grams ( about the same as the frm). The reason they were refered to as not good brakes was because they are single pivot, not dual. The only reason it came up is because I had allready optimized ( lightened ) my front dura ace dual pivot down to 126 grams and didn't want to not use it. I hadn't done that to my rear dura ace so it sits on a shelf now. Hope this clears up any misunderstanding.

I'm going to try to post an explanation and photos of how I optiomize components. A fellow bike rider offered his digital camera. I do not know how to do this so bear with me.

I have had CAT brakes on my bike for two months and they do everything they promise. The brakes weigh 102grams complete with interchangable pad holders, and they stop better than my Record brakes. There is virtually no flex out of the brakes and they look swweeet! Well worth the money! They only small complaint is that the quick release is a little hard to grab. Other than that it's all good!

To popawheelie: What's the difference between single and dual pivot brakes?

OK! I have the FRM brakes in my bike from 6 mounths, the weight of the two brakes is 230 gr. I think the rear brake will weight less than front, it has the principal bolt smaller than front. All bolts are on titanium. The pads are Ritchey and they brake more than Dura-ace.
Realy they are a Dia-compe BRS 200, and they have changed all the bolts on titanium, hear you have the information of the brake on their web page.
