    Where to get "Low profile" alloy bolts?

    Hi

    I want to swap the Ti bolts on my Juicy Ultimates to Alloy to save weight. The stock TI bolts are something like M5x15mm but with a low profile head..

    Now i know of Tasty nuts etc etc but does anyone know if they actually do low profile bolts? Or anywhere else for that matter....

    Its not the rotor bolts its the lever clamp bolts. There Ti - don't need them to be Ti really. I'll give tasty nuts a call in the morning.

    Why do you need low profile head bolts? Normal profile aluminum ones work fine.

    Because normal height bolts will look daft on the levers...

    The big risk with the low profile head alloy bolts is the shallow Allen socket is very prone to being stripped out.

    If you went with plain silver alloy bolts you could always turn the head down with a file once the threaded portion in an electric drill. You could actually do that with the Ti bolts too.

    Low profile aluminum heads don't work very well and are harder to find. Stick with the Ti.

    low profile means less material and since Al is weaker it would not be a good idea. but what's the problem with a 1mm higher head anyway???

    who cares about the1 or 2mm??

    shown above is an uncut rear brake with loooong brakeline.i actually use a 140 rotor now so the actual weight should be more like 270-280g.

    by the way - i just found an old thread where i described the individual savings on my Avids:
    Avid Juicy Ultimate weights (out of the box, uncut hoses):

    FRONT (185mm rotor): 413g (includes 35g for the adapter. if you have a postmount fork you won't need it)

    REAR (160mm rotor): 389g (again includes 35g for the adapter)

    my tuned Ultimates weigh:
    front 180mm: 368g (including 35g for the adapter)
    rear 160mm: 306g (including 35g for the adapter)

    tuning consists of:
    Nino's lightweight 180mm rotor 115g (- 29g)
    Nino's lightweight 160mm rotor 92g (- 17g)
    4 Titanium bolts M6x18, standard is steel (attaching the brakes to the frame and fork) (-9g)
    4 aluminium bolts at the lever clamp, standard is titanium (- 6g)

    total saved: 61g

    i will change to a 160mm rotor in the front as well. right now there's too agressive power on hand. so my setup will weigh ca. 640g total (both adapters included, so it would be 570g without them).


    so actually my brakes as used today weigh:

    front with 160 Alligator rotor(no adapter...Postmount): 325g
    rear with 140 Alligator rotor (including adapter): 274g
    Total: 599g (not so bad! i will get some Al-mounting bolts for the calipers and maybe for the rotors as well...should save approx. 10-15g)

    Mine:

    Front post mount trimmed hose no rotor 236g
    Scrub 160mm rotor 56g
    DT Swiss Centrelock adapter 29 g

    = 321g

    Rear trimmed hose with adapter + adapter bolts no rotor 261g
    Scrub 160mm rotor 56g
    DT Swiss Centrelock adapter 29g

    = 346

    Total 667g


    These are with Steel backed pads too. Alloy backed ones save 24g so make it 643g

    Here's a though.

    My headset bolt is alloy M6x30mm with a counter sunk head. It doesn't have much material in it and has held up fine - will the alloy bolts on the levers be bad? IT's not like there getting massive torque....

    Well just to bring this back up.... I actually got some new Ultimates - some White ones....

    Damn light too! The front lever,hose, caliper & pads& bolts is 220grams ! Which is right on the weight of the hope Mini/Mini Pro

    http://julmtb.com//composants_legers...O_MINI_avt.JPG
    http://julmtb.com//composants_legers..._n_5_S.I._.JPG

    It was 223g out of the box and trimming the hose saved 3 grams.

    The rear untrimmed was 260g
