    Best Light V Brake Pads?

    Hello,

    I was curious if there is much of a consensus on what are the best light V Brake Pads these days? We've been getting quite a few requests for this info to set up our Magnesium MOC V+ and we aren't really certain what to suggest. We've always liked to build up light bikes but are a bit behind in knowing how far you can go. Thanks for the tips!

    lot's of choices...

    i'm a specialist regarding light v-brakes and also pads!

    if you want the lightest you should spec them with road-pads.Jagwire has some nice carbon ones. those fit and do a great job.

    if you want to use MTB-style pads you need to look for lightweight bolts and nuts to tune them. standard MTB-pads weigh around 50g per pair, tuned ones ca. 35g. lightest tuning are some aluminium bolts and nuts like i have in my V-Brake tuningkits pictured below. pair them to lightweight padcarriers like Avid and you get the lightest MTB-setup.

    pictured below:
    -a typical set of MTB pads: 49g
    -Jagwire Carbon roadpads: 33g
    -V-Brake Tuningkit: 19g
    -same steel bolts of a standard V-Brake: 68g

    if you need more info send me a PM.

    Nino, do you have a weight on the Kool Stop thinline pads? They are not a replaceable cartridge pad and look to be a little lighter then the replaceable cartridge types from my crude in store weight comparison.

    I have tuned xtr padcarrier with alu bolts+nut .. they weight 34grams incl pads.

    68grams for front+rear.

    Where did you find a source for the alu bolts/nut and how has that held up under braking forces? I was considering the same route but I worry about the strength of the alu for this application. If you have a pic I'd love to see your tune job. BTW, I just picked up some of the Kool Stop thinline pads. I'll weigh them when I get home from work and report back on the weight.

    i don't have any good picture of the padcarriers 'cause of a harddisc crash earlier today.

    this is what picture I have:


    the nuts is from nino's tuningkit for vueltas and the bolts is m6*25mm 7075-t6 bolts with cutted heads. thies bolts comes from a motocross shop. (also avaible to buy from [url]http://www.mmm-bikes.com[/img]

    I trust alu bolts for the padcarriers, i hav ride thies padcarriers for a mounth on the trainingbike to se if it's holds up, and it does.

    Wow! That's LIGHT! So, it looks like you took the drill and file to your Mrazek's. Is this standard practice with the Mrazek's? Fairwheel did the same thing. Nice.

    dremmeling...

    dremmeling is not what he is looking for.

    i also have tuned MTB pads that weigh 32g per pair but that's not what he is going to sell with his brakes. the tuningkit however is a viable alternative to make V-brakes almost 50g lighter.

    below is my set of tuned MTB-pads...63g

    and a comparison of Avid Padcarriesr and nut and my aluminium padcarrier with nut.

    it's not mrazek brakes. it's homemade ones. milled out of a block of alu.

    OK, so now I'm even more impressed. How do they work? Did you fabricate them?

    Thanks

    Hello Everyone,

    Thank you so much for all of the great information. I've never tried road pads on our brakes but may have to give it a shot. Nino certainly seems to be a fantastic mentor! I'm going to have to check in with Jason at Fairwheel again, too, since I thought he said he came up with a 19 gram pad set. No wonder you guys all float up the hills!

    Best to You All,

    Jeff

    there's even lighter ones BUT those roadpads are supposed to be used on carbon rims. i think it is very important to have that variable angle option in a MTB-pad. several lightweight roadpads don't have that feature and stay in that one position once mounted. also you need to have replaceable pads since on a MTB pad wear is a factor and we all want our best performing pads anyway.

    the Jagwire carbons i mentioned in my 1st post still have that option though unlike the BTP carbon pads pictured below. but then those weigh just 30g (all four!).

    I rode them today on a 2H riding. works excellent. proberbly I'm going to have them on the racebike 'cause I save 72grams over my vueltas with same padcarriers!


    And yes, I fabricate them by my self in the miller.

    So the BTP's are light but why do they even enter the discussion if they don't work on V-brakes? Now I'm sorry I ordered a pair! B-T-P's website says "adjustable" but I understand how road pads typically aren't adjustable. The biggest problem I can see is reaching the rim. Cranky . . . perhaps I can mend them to work . . .

    bravo tim!

    Is it safe to say that tim- here has produced the lightest MTB brakes in the world?

    I've been using Al padcarrier bolts and nuts for over a year now and they are great.

    I also acquired mine from Michael Metje (www.mmm-bikes.com). He seems to be the main supplier.

    no he is not the main supplier!

    i once dealt with that guy and he is a big jerk and cheater. the same reason why his bikes got removed on light-bikes.com...i dealt with many,many guys over the last 15 years but never was cheated like this before.

    i now have the same tuningkits as well. own fabrication. best quality.

    I created these cantilever brakes---63 grams a pair

    http://plusonelap.blogspot.com/2006/...-63-grams.html

    I used road pads as well, koolstops that i tuned with aluminum bolts as well.

    Wow, nice. Let us know how they work. You and Tim have inspired me to have a go at creating my own V-brakes. As soon as it gets warm enough for me to work in my garage I'll get started. I have an idea for a new material TBA. My Mrakeks have just been set up on my new bike and I can't be happier with them. They are really smart brakes. The design is the best of any Vs I've used. Tons of power and easier to adjust the spring tension then with my Avid SD Ti or my XTRs. The tension adjust is more accurate with these and seems to stay in adjustment better. I like my brakes set up really tight so this is a big plus for me. Hyperbolts will be fabricating Ti padcarrier bolts and nuts soon. I just sent them off a set of XTR steel hardware to copy from.

    i would like to see you brakes when you have made them.
    I'm trying to get some magnesium blocks to made a lighter pair of brakes (if it don't cost too much).

    otherwise I have to say I have been little bit buzzy the last weeks and havn't even start making my brakelevers as I said before.

    what are you going to make your brakes in? alu? carbon fibre?

    It's a secret...for now. I'm not sure what I have in mind will work yet so I want to have a go at it first before I "go public." Right now we are experiencing the end of winter here in Minnesota. It's been just above freezing and my garage workshop is unheated so this will have to wait for warmer weather.

    why Titanium?

    it's almost double the weight of aluminium which does an excellent job.

    pictured below:
    SRP titanium padcarriers: 7,3g
    my Aluminium Padcarriers: 4,0g

    so the Aluminium padcarriers save 6,6g total over the titanium ones. the same savings are achieved with aluminium nuts...
