    lightest hydros?

    Somebody probably knows this off the top of their head, thus saving me from a lot of busy work. What are some of the lighter hydraulic disc brakes out there? The application is for a lightweight SS 29er that I wouldn't be riding on wicked downhill stuff, so they don't have to be the strongest brakes. I love my Juicy 7s on my AM rig, how do they rank in terms of weight?

    Thanks in advance.

    Magura Marta SLs are very light too, but are heavy on the pocket

    Don't forget the Formula's Puro. That'd be my pick as they work great and are as light/lighter than every brake listed thus far I believe.

    The lightest ones that ever hit the market were Formula B4SL Magnesium at 630g for the full set (my weight; my scale). The rear rotor was 140mm. They have been off the market for a couple or three years and NO I won't sell you mine

    Chain reaction has some NOS B4 pro plus for sale http://www.chainreactioncycles.com/M...x?ModelID=5691
    Still,none of the brakes listed are as light as the Hope mono mini pro that comes in at 295g.As Hope says,thats including all the parts needed for use.

    If you use the mini rotor (pro version) with the Marta SLs, you'll be at the same weight. Claimed on the Martas is 327 or so, say 330 to keep it simple. Marta rotor is 108g. The Mini PRO rotor is 78g, 30g ligther. Put the mini pro rotor with the martas, you've got 300g martas. Throw in Ti hardware like the mini pros have, even lighter still. You'd be really stepping up the price...but what can you do...

    They superceded the B4SL Magnesiums and weight was added.

    If that's their true weight then I stand corrected about B4SL Mags being the lightest at 630g. I'd sure like to weigh a set of those Hopes though.

    In "What Mountain Bike" this month they tested brakes, hope mono mini pro was 304g with 160mm rotor, atleast 50g lighter than any other brake on the list including marta sl and formula brakes.

    Interesting tidbit from the Magura rep at the NAHBS,the new Marta magnesium will come in at 300g including all parts.And yes,that does include the Magura rotor.
    Just pairing the hope pro rotor with the new Marta should make it the lightest by at least an ounce per brake.

    How many guys put all kinds of dough in Magura Marta brakes and then want to sell them. I sold mine like a house a fire; piece of crap brakes! Things that make you go hmmm.

    The marta magnesium? I've not seen anything about this on any cycling news outlet or forums - do you have any more details? How do they differ to the SL?

    The rep was only expounding on the weight benefit,I doubt that there is any change in performance relative to tho SL.He did show me the 08 Magura product line catalog which features the magnesium version.

    So what are they doing different in the magnesium version to the SL version? It'd be fair to guess that the calliper body will be cast in magnesium, but are there any changes to the lever body housing?

    Also, here's the '08 catalogue: http://www.magura.com/7thsenseCMS/fi...e2008_E_wP.pdf

    There's no mention of it in the current version. They claim 324g for the SL, so obv. they're saving 24 grams by at least reworking the calliper?

    I think the Marta Sl's are lighter than the formulas?

    I have been running Marta SL's on one of my bikes since September and they have been running sweet with no need for any adjustments since, with frequent riding. Super happy with the brakes, modulation is awesome.

    Juicy Ultimates are super light and can run a 140mm rear rotor. The bonus is that they work too!

    Well...the suspense is killing me!! Magura USA knows nothing (or claims it) about any update to the Marta.

    Just a word of caution : with most other disc brake systems, the bolts of the Hope floating rotors tend to rub on the caliper (if I remember well). Anyway, a compatibility check is mandatory...

    Too bad you're right... I really loved my Martas but these brakes (apart from the frequent bleedings they need) tend to age badly. During the first 2-3 years, they perform flawlessly (except, as said, the mandatory bleedings once in a while). Then, I started to have problems... More and more bleeds and inconsistant lever reach. Finally, one of the master cylinders died and had to be replaced, since Magura doesn't sell individual parts to repair them. Then, after a few hundred $$$, I go riding and guess what ? The front caliper gets stuck. We've tried everything to get it to work again, to no avail. So, now, I have to change the other master cylinder...

    In the meantime, I've put a set of Avid Juicy Ultimate on my FS and the Martas were installed on my hardtail/mullet bike... Even though the Juicy are not as powerful as the Martas, they seem to be reliable, at least... :|
