are all dual pivots equal in performance?

I need some and, to me, they look very similar

eg 105s (£37 at CRC)

look very similar to Ultegra (£55)

now I acknowledge that this is a 'how long is a piece of string question' to a large extent but can anyone detect any significant differences in use, weight or finish, which would suggest spending more is worth it?

Any comments welcome.

    Hey there,

    If I were in your position and the callipers came without pads, I would buy the 105 set and spend the difference on a good set of pads. The cables are also just as important. I changed the cables over on my bike a couple of days ago, and the difference is unbelievable.

    I certainly wouldn't spend more for the Ultegra set.

    Cheers

    ta pedro. I'm going to run ceramic pads I think as the rims are ceramic, although I'm not 100% on that yet. I might have a play around with the standard ones first to see how they perform.

    Anyone use Tiagra, as they're even cheaper....

  • I have Tiagra equivalent but with slightly longer reach on my SCR. Seem fine to me but I did change the front pads to get a bit more bite. Still got the lever with multiple stops to adjust the cable position.

    Hope the brakes in the pictures are rears!

    Do you think I would be this bad on drugs?

    Tangent but....only once ran ceramic pads on ceramic rims (XTR Vs on Cross Max, but fundamentals hold). The squealing was so bad that they were dangerous - I didn't dare apply the stoppers from embarassment!

    I currently run ceramic pads on ceramic OPs (with Avid ultimate Vs) and they're fine. Superb perforrmance wet and dry, and a clear step up from standard pads and rims

    But the ceramic wheels are going on the missus's bike, on a flat-bar build based on a standard road frame, hence the dual pivots.

    I think I'll probably go for 105s. CRC has the older versions for £30 a pair, which is a good deal.

  • I just picked up a set of these babies:

    They have the nicest quick release mechanism I've ever seen on a brake. It has these lovely little clicks... more what you'd find on an expensive camera... can't wait to use them but I don't get my bike for another 2 weeks. :(
