    Hope Tech V4

    Anyone on these yet? How do they compare to the M4s? Anywhere available to purchase in the states?

    Only just released at Euro bike, so probably not available til next year. Meant to be the successor to the V2, so a whole hell of a lot more powerful than the M4.

    Email Hope US to find out more.

    Hope says they were released last week. CRC appears to have them in stock. Might have to jump on a set.

    Go for it! Would love a ride report. Apologies - normally they take a while. Hence their seatpost is named Eternity....

    Saint's do indeed look the part, but I REALLY like the simplicity and adjustability of the Hope's. That and the lever ergonomics just fit me better.

    I would agree with you there. And the Hope's are just plain sexy

    So whilst I was looking at bike pr0n... I came upon (sorry for pun) this on an Italian website:

    Hope Tech V4-1283_img_0968.jpg

    Hope Tech V4-1283_img_0971.jpg

    Hope Tech V4-1283_img_0970.jpg

    What gives? Hope's website lists the regular silver/black version and the all black "Stealth" edition only... nothing about any other colour combination.

    I bet those are custom one-offs that company makes. Take the stock silver and blacks and you can have them anodized what ever color you want.

    They look like a special edition for one of their pro athletes. I forget who, but he has all red anodised Hope bits hanging from his bike.

    Kill two birds with one stone... from what I ascertain from the Italian, this is an actual option. If they just colour-anodised the regular silver parts, then the laser etched stuff would be coloured too (see i9 "Black I"/"Red I" wheelsets, with "double dipped" hubs). Bit crazy to laser-etch them a second time (what with reverse engineering the etching, alignment, etc). Plus that isn't "all red", of whichever pro athletes is supposed to have on their bike. I fired an email off to Hope UK and see what they have to say for themselves about those strange V4s... if they reply at all.

    In the meantime, I'd like to see a ride report. The V4s are supposed to be about 15% more powerful than the superseded V2 on the same rotor diameter. So V4+160mm ~= V2+183mm, V4+183mm ~=V2+203mm. V4+203mm = insane. That also means a V4 with a puny 160mm rotor (as the rotors across the range are common once more) is comparable to an M4 with 203mm rotors. Ouch.

    From the horses mouth... turns out DSB Bonandrini is the Italian distributor. Explains some gold, blue and gunsmoke coloured 1st Gen Tech X2s I saw in Hong Kong a few years back. Looks like you guys in the USA might get lucky if you give Hope USA a good nag?

    V4s ordered, should have them late this week or early next I will be sure to report back comparing them to Tech M4s.

    Would be keen to hear how they compare to M4 and maybe X2, but I guess that comparison would be obvious.

    Oh, and pictures please

    Will post when I get them. I honestly don't know why I am buying them. The V2 is good, but my old 6 piston ti was better. Not a little better, but a LOT better than the V2, no matter how much Phil at Hope tries to tell me that the V2 is more powerful. It's not. Don't get me wrong, the V2's are really powerful, but the old 6ti was unbelievable. But the hopes are just so good, I just never have any issues with any of them. Such a set it and forget it brake.

    Agreed. I love Hope brakes, honestly, other than wanting more power, there is no reason to replace my M4s, they just work. I have tried nearly all brakes, from Avid to Shimano to Formula, and I like Hopes the best.

    I loved the Tech V2s, but I think some of your power comments came from the flexy caliper. I was told it was "tuned flex" which is what gave them such great modulation.

    I am hoping the new V4 has the smooth power delivery of the M4s If the power claims are true, then this brake will be rediculous.

    That's what I am thinking TiSSer. I use the EBC reds on the V2's and the x2's as well and it helps. I think the V4's should be about 20 percent better, but will find out. Phil told me that I had to order new disc's as well, and I did, but will see if they are the same as the old ones. He did tell me at one time that the V2's took a wider disc, and it doesn't. If he does this again I won't be happy with him.

    He told me my M4 rotors would work. The pads are different however. I hope he was able to ship them out today so i have them for the weekend!

    From what I can ascertain about the V4 online is that pad area is greater than the V2, though the track-width is the same as X2/M4 (and thus use the same saw-tooth rotors). This means longer pads... just like the 6Ti, though obviously the 6Ti is 6-pot.

    We know the V4 has a 18mm leading piston, with the other being a 16mm piston (straight off the M4). What are the 6Ti's piston diameters? Difference in mechanical advantage can be worked out from that and infer whether the V4 or the 6Ti is a stronger brake.

    No offence, but this is your 4th post and you have questionable rep. Not that rep makes a difference, but the post in itself is in question. I think I will get my new brakes though Hope.

    Has anyone figured out (or I may have missed it), do the V4's use regular rotors, or do they still use the vented/non-vented V2 type rotors?

    Edit: Post 27 may just have answered this....

    Ditto. And on Hope's website, the Stealth edition brakes are shown with the V4 vented rotor... where the brake track looks the same as the Mono Mini/X2/M4 saw-tooth rotors. Which actually gets me wondering... would V4 vented rotors work* with X2/M4 calipers?

    *I know the V4 vented rotor is a bit thicker, though this time round the difference doesn't seem as drastic as it was with the V2 rotor type.

    I don't mean to sound like a jerk, but you really need to do adverts though mtbr. Not only that, but how can you get deals on Hope that none of us can't get though their Texas distributorship? Also if you are a rep of Hope, I don't think they would take kindly to this type of advertising.
    Also you have done something to warrant a negitive rep, which is why you have a red dot under your name.
    Can you explain how you get deals with Hope?

    My V4s came in today. Mounted them up to my existing 183mm floating M4 rotors. The rear brake was spongy, so I bled it (did the front as well). I would have bled it anyway since I like to run Motul RBF600. There was some air in the lines, but all is good now. I did destroy my rear rotor on Sunday's ride, but was able to true it up, so that may have played a bit in the mushy feeling lever as well.

    Mounting was easier than ever. The brake lines were the perfect length, so no cutting needed. I did pull the brake pads out and compare them the M4 pads, and they are slightly larger, but it is hardly noticeable to the naked eye. Hope sent me both organic and sintered pads, I left the organics in as I figured I would give those a try. I typically don't like the grabby initial bite that organics provide.

    I did spend some time running up and down the road, bedding in the pads. After about 10 runs per brake, I think I can make a few qualifications.

    1. They are very powerful. Are they stronger than the V2s? It has been a while since I rode my Tech V2s with 203/183 setup, but I think so. They are more powerful than the M4s, and it comes on quicker. However, the modulation is excellent, and it doesn't feel like any modulation has been forgone to achieve the power.

    2. The organic pads feel very nice. They have a softer feel at the lever than the sintered pads do. Sintered pads seem to give a stiffer lever feel. So far, they are dead silent. That may change though with the dusty desert conditions I ride in. In the past, sintered pads have run quieter than organics.

    3. Setup was typical Hope. After working with Hopes, it was very quick.

    I am hoping to get out on the trail tomorrow and do a fair break-in. I will report back after some real time on them. Basically they feel like more powerful M4s, and that is exactly what I was looking for.

    If V4's on 183F/183R feel more powerful than V2's on 203F/183R, what with most of the braking done on bicycles with the front brake... then colour me impressed! Now just waiting for mazspeed to chime in to see how the new V4's fair against the "older but still better than V2" Mono-6Ti.

    @tiSS'er: So it does indeed seem the V4 uses the same rotor (and thus track width) as the X2/M4? Eyeballing it, you reckon a V4 caliper will work with the 160mm and 140mm rotors? I have my reasons...

    I didn't take any photos as the lighting was pretty poor. What would you like to see?

    I don't see any reason why they wouldn't work with the 160/140 setup. I have a 160 floating rotor at home which I considered putting on to give me a bit more clearance in the rear.

    I will be heading out tonight for a ride, I will report back with details.

    Will let you know, I am getting them this week.
    I have really big tires now, 2.5 front and 2.3 rear on my HD so if the V4's are better, I will know right away.

    I did promise a bleed write up. Mine is not as detailed as this would be. I do a few things differently, but this is spot on if you need to bleed your brakes.

    I got out last night for a short ride last night and came away impressed. The power was great, although not overwhelming. I feel as though the power is getting better with every downhill. It has been a while since I used Hope pads, and if I remember correctly they take a bit longer than most to bed in properly. Combine that with the fact that I am using older rotors and it makes sense. That being said, they are already very strong, and should get stronger with a few more rides.

    The beauty of the Hopes is the modulation. I ride in the desert where we have lots of sand, crushed granite, and loose conditions. Braking to me is more about control than flat out power. My concern with the V4s was that I was going to lose modulation over the M4. I actually think the modulation is better with the V4. You can dial in just the right amount of power and the power is very progressive. With the organic pads I feel like i get better feedback from the brake. The brakes were dead silent which is a plus.

    I can't wait to get some more time on them, but I think these are a great setup.

    Sounds awesome... I assume you didn't put them on a weight weenie scale, though in just taking the old M4s off and putting the V4s on, are they lighter, much the same or heavier? I ask as the V2 with braided hoses was actually lighter than M4s with Tech levers + braided hoses. The extra heft of the V2 set up was the rotors. As the V4 now uses the same rotor as everything else in the Hope range... and the V4 is lighter than the V2 "as an overall setup" (says Hope), just curious how much difference there is with the M4?

    Sorry, I didn't weigh them. Weight really doesn't matter to me too much, more interested in performance and durability. The are certainly lighter then V2s simply due to the rotor.

    The new V4s work great with the regular HOPE 203mm rotors. TiSSER pretty much described its performance when compared to the M4s - No modulation loss but improved bite.

    Depending on front fork and front hub there might be some rubbing of the rivets on the inside of the fork brake mount if using HOPE's floating rotors (I experienced the following below for both HOPE 183 and 203mm floating rotors. Regular rotors no prob.

    CK front hub with FOX 36 fork = rubbing

    Hadley front hub with FOX 36 fork = rubbing

    HOPE Pro 2 Evo front hub with FOX 36 fork = NO rubbing

    There have been posts already regarding more severe rub if using HOPE vented floating rotors over the normal floating ones due to the slightly wider profile.

    In any case, I contacted CRC as to when HOPEs new 2013 floating vented rotors and V4 pads would be out. Here's what they wrote:

    Thank you for your email.

    The Hope V4's uses the same floating rotor as the V2. You can also use the standard Saw Tooth floating rotor used with the M4 and M6 caliper.

    With the V4 brake you are restricted to using 203mm vented rotors only. If you wish to us a smaller size then you have to use the standard solid type floating rotor.

    We currently have no date from Hope as to when the 2013 rotors/pads will be in stock. I would suggest that it will be early next year.

    CRC clearly think we are fools and/or blind... Hope's own website shows the V4 vented rotor:

    Stealth Tech Evo - Stealth Tech Evo Product Details

    ... and PinkBike show it (V4 vented) being much slimmer than the V2 monster, much more like the regular saw-tooth rotors:

    in Wester Ross, Scotland - photo by cloverleaf - Pinkbike

    Of course, V2 rotors would work... just would be carrying a lot of excessive unused steel!

    Edit... Dart @ Hope UK replied in a record 7 minutes!:

    Hi, the V4 uses a different vented rotor to the older V2.

    Cheers,
    Dart.

    My front V4 weighed 320g on the Alpine digital scale. Thats lever, caliper and Goodridge hose- no bolts or mounts etc.

    The brake it replaced was a last gen XT, the M775 and that weighed 280g - without braided hose. I think that would account for 40g. All in all, i think it's a good weight on the V4 for what you get.

    Hope now send the brakes out with both types of pads which is a nice touch. I compared the pad size with some others i had and they are a lot bigger than the XT and almost identical to Magura Gustav in width and length.

    Not had chance for a decent ride yet, but just up and down the road trying to bed them in and they feel nice and strong.

    Errrm. Wow! Tech V2s were 343g... and Tech M4s with braided hoses were/are 352g. So Tech V4s, even with braided hoses are about the same weight as Tech M4s with black lightweight hoses. Yet obviously more (though very controlled) power. And literally just ~30g heavier than Race M4s. Crazy!

    Looks like Hope will have to do some revisioning and extra CNC work on their M4 and possibly X2... with more finning and moving the hose inboard. Otheriwse, if you were using Tech levers... may as well just use a V4 if an X2 isn't up to scratch!

    Just dug up some old weights of my own for comparison (not that i'm a w.w. or anything, you understand!- just weigh stuff out of interest)

    front Tech V2 (old style) - 330g

    front Tech V2 (newer style with smaller calliper) 300g

    front Tech M4 (plastic hose) 270g

    front X2 Pro 210g

    So, going off my scale, the V4 is around the same weight as the original V2 (which uses heavier discs) and a tiny bit heavier than an M4 with the same hose.

    I have the V2 203 disc at 200g and the M4 203 disc at 170g. This would make the new V4 and outgoing V2 the same weight to within 10g.

    So Hope's claim about the V4 being lighter overall is true. ha ha.

    Bear in mind my scale only goes to the nearest 10g i think.

    Anyhow the weights might be interesting but it's how the brake performs that really matters of course

    Ah... thanks for the correction/update. Indeed don't really care +/- 30g or so... considering they'll be stopping a mass a couple orders of magnitude greater (60kg~200kg... tandem teams!) that's moving at a fair rate of knots.

    I only got one more ride on them and I am impressed. I am sill running the organics and I think they are still bedding in. It seems that every time I grab them they are getting stronger. So strong in fact that i am considering dropping a rotor size. With the organics, I I initially felt that the modulation was better than the M4s with sintered pads. With more time, I think I am missing some of the modulation at the very beginning of the stroke. Most likely this can be remedied with more time, and me simply using less pressure on the lever. I am still trained on my M4s. If that doesn't work, I will try the sintered pads that Hope sent me. I have always felt that sintered pads give you more linear braking, where organics are more grabby initially.

    Not an apples to apples comparison, but I do have 2012 Shimano XTs with icetech pads and rotors on my 29er. The V4s are significantly stronger and smoother. I couldn't say that about my M4s.

    You're running 183mm front+back right? You thinking of dropping down to 160mm just on the back or on the front as well(!!)? Mind if I ask what weight you are "ready to ride"? Because that sounds like seriously strong brakes!

    Indeed, believe me, I know, Hope is dope. I have about 6 pairs of old M4, Mono M4's and two pairs of Tech EVO M4's. "Hope Brake Junkie" I'm 250 lbs. RTR, I'm running 203 front and 183 rear. I love the Tech M4's but, the ability to possibly run 183 front and 160 rear with the V4's does peak my interest as does the feedback on different pad compounds.

    Just to clarify, are they dumping the V2?

    I'd love a V4-183/V2-160 setup . . . .

    Yes, the V2 is dumped. The 160mm fixed trials rotor will work on the V2 (same basic caliper design)... though considering the improvements on the V4 over the V2, what's wrong with V4 with 183mm/160mm rotors?

    As the Hope brake range now use the same rotor across the range, I hazard an educated guess that the 140mm rotor will work too. Would be ace if someone can try this on their V4?

    I personally like the simplicity of a 2-POT design. Fewer moving parts to foul up . . . .

    Finally got them hooked up. These things are pretty light, and very grippy. Will take them out today or this weekend.

    @Mike: What size rotors you got front+back on there? They look like 183mm/160mm, though wouldn't want to ass-u-me.

    Edit: I see mount "C" up-front, so that's a 203mm... so 183mm out back? Looks mighty small... though that could just be the longer V4 caliper!

    I just now noticed that the banjo bolt has been repositioned and so has the bleed nipple. I like it. MUCH smarter design.

    wow I dint even notice you said V4 not M4 I didn't even know they made a V4, my LBS didn't either nor did his supplier LOL, they do now though, waiting on a price for these bad boys. I think I am also geting the stem and seatpost clamp, going all red hope.

    If I'm not mistaken, it uses the same pads as the M4, so pad area is...........identical.

    Well, if that is the case, the Hope really must be smoking some strong crack to issue new part numbers for their V4 pads (organic: HBSP303, sintered: HBSP303S) when the M4 ones, which in turn are the same as the Mono M4 pads (organic: HBSP130, sintered: HBSP130S)... would have sufficed.

    Pads -

    Not to mention defy Physics in having a stronger brakes than not just the V2, but the 6-pot Mono6 as well... all with just increasing the lead piston diameter from 16mm to 18mm.

    I read in some threads that some people think that Shimano Saint and Formula The One are more powerful than Hope V2, but since these V4 should be more powerful too, do you think V4 has more power than Shimano and Formula or not?

    p.s. I still don't understand if the only difference between M4 and V4 are (one) piston size and pads.

    (sorry if I made some grammatical mistake, english it's not my main language )

    The V4 pads and the M pads are different, but I cannot tell you how much different as I have never had any of the m stuff, but was told the pads are different.

    The shamino brakes are very good, I have a set of XT's on my tranny and they work great. Not really super powerful, but a great brake none the less. A true 1 finger brake, but I would not use it for downhill or heavy AM use if you weigh over 200 pounds. The new saint coming out looks pretty good, but I have never tried it. They have had a lot of issues during pre-production, but I don't know if that's all sorted out. Shamino is a good company and I'm sure it's a good brake, but I have no experience with the saint. The formulas are junk, flat out junk. You should never consider formula brakes. Do a search here on them and you will know why.
    I have had some in the past and could never sell them. Had to throw the overpriced formulas "The One's" in the trash which pissed me off because their CS is terrible and won't fix or help with their issues. They know they produce a crummy brake, and don't seem to care. $400 online buy, 2 weeks later I put them in the garbage can. I have run Hope's pretty much for the past 8 years or so, but tried things here and there to try stuff out, and there is no better brake in the biking world than Hope. Period.

    Looks like the pads ARE larger. It's not the same pads as the Hope M4/Shimano m755.

    What's about ride the new V4 vented disc, which has standard track width, with a non-Hope caliper, do you think it's possible?

    Hey Overdrive, I am not sure what you're asking. The v4 disc is standard size if that's what you meant. I was told it is different, but it's the same as any other 203mm 180mm etc. I hope that helps. You can use other discs for that brake if you want, although I did have issues with Shamino ice tech rotors in the past.

    I think he's asking about the rotor thickness. The regular (fixed & floating) Hope ones 2.0mm. The weight-weenie XC ones were 1.8mm. The vented V2 rotor was something like 3.0mm. Most calipers physically don't have the space to fit a V2 rotor unless the pads were (really) worn down. No idea about the V4 vented rotor's thickness...

    I think that's for the vented rotors only, not the standard ones they sell. I'm pretty sure

    yes that's what I mean...

    I think the V4 vented rotor thickness will be the same as the V2.

    Yes, the V2 fixed and regular floating are also 2.0mm thick.

    As for the V4 vented rotor... the perspective is tricky. If the steel is 1.0mm, and the gap is roughly the same size, that would end up being the same as the V2 vented rotor.... 3.0mm.

    Though only a tiny bit thinner at say 0.7mm, that would make the overall width 2.1mm. Pity don't have one to hand and a set of vernier calipers!

    sorry for spamming, but this thread seems to catch the essence of Hope users in this community.

    I'm interested in getting Stealth V4's for SX Trail as I use it as a lite DH machine and I think they will be perfect for that.

    my question is whether you guys think would Stealth X4 be good for S-Works Enduro? I think they'd be perfect, but just wanted to hear the expert opinion - and which rotors should I get for the job? sorry for this brief thread hijack and thanx for the answers.

    You don't mention your "ready to ride" weight, though Hope's website suggests Enduro/Light DH to use something like 203F/183R with the V2. Given that the V4 is even stronger than the V2, whilst there's no such thing as being "over-braked" (especially with the modulation Hopes have), I think for your usage, 183F/160R will be plenty with the V4 front & back. tiSS'er said he's considering dropping a rotor size down...

    hey StanleyJ, I've made a mistake.
    I wrote Stealth X4 and meant X2, not V4

    I read that these new Stealth X2 are great for AM riding, but seems to me Stealth M4 are superior to them, as the chart shows.

    I'll be defo running 203 front and 183 in the back as I really like the look of big rotors. maybe I won't need that much power but who cares - I just love the looks.

    V4 might be overkill and there's no V2's anymore, so I think I'll go for Stealth M4's as they seem to be spot on for enduro riding.

    I'm around 95 kg in full gear.

    Last year's V2 are still stocked, though they are a heavy and very full-on DH brake (because of the huge 20mm brake-track disc). For non-DH, they are for tandem teams or very heavy/hard riders whom cook "normal" brakes for breakfast.

    X2 will probably be under-braked for you, even with 203mm rotors front and back. If you care about weight and don't mind mixed calipers (different pads!), you can run M4 on the front and X2 on the back. There's also has the choice of Race levers (with reach but no bite point adjust) rather than chunky Tech levers.

    Going Tech M4 with braided hoses... there isn't much difference in weight between that and the V4, the V4 is a bit of a no-brainer in that case, what with the better heat dissipation and tidier hose routing.

    For reference, I'm ~70kg and run Race M4's with 183mm front+back on a 29er AM hardtail... and it's easy 1-finger braking. Handy when you have tired arms!

    which one you'll advice for an heavy DH rider (~110kg fully equipped), considering braking power and heat management:

    - Tech V2 front/rear with V2 vented rotors
    - Tech V4 front/rear with new V4 vented rotors

    ?

    The V2 uses the standard rotor, so it's the same weight as the others. The V2 caliper is not that heavy, at least to me. Although I have not put them on a scale.

    The only thing to make the V2's heavy is the actual rotor as the track is deeper due to the size of the calliper catching on the rivets on the standard floating rotors.

    Is the new V4 vented rotor available in the shops?

    The V4 will take both vented and non vented. Not sure if their in the shops yet. Not around my area.

    CRC said "middle of November". I asked them why it isn't already on the website so as to set up an in-stock notification... they said "we'll look into it".

    So we patiently wait...

    I think you answered your own question, unless you for some reason prefer the simplicity of 2-pot vs. 4-pot... or you see somewhere which have V2's at a nice discount, want something a bit cheaper and don't care about the extra weight over a V4.
