Hope Tech 3 V4 Disc Brake
We have kept the key features of the Tech Evo master cylinder and worked to improve the ergonomics and integration on the handlebars. The Tech 3 master cylinder can operate all the calipers from our range and offers a slight increase of power of about 5% over the Tech Evo.
Popular design features of Tech Evo remain the same, such as the reach and bite point control (BPC)adjustability. The piston is actuated by a cam and a roller system to eliminate any free play and initial friction. The classic split clamp design makes the master cylinder easy to install on the handlebars without having to remove anything else.
Hope Tech 3 - Some riders have previously commented on the relative bulkiness of the Tech and Tech Evo master cylinders, sometimes making it hard to fit the master cylinder around already clogged up handlebars (shifters, fork and shock lockouts, telescopic seat post controls etc).
Hope have worked hard to make the new Tech 3 master cylinder easier to integrate on the bars although it does entail losing the ambidextrous design. The Tech 3 master cylinder is now directly compatible with any Shimano I-Spec type shifter meaning no extra mount is required to attach the shifter to the master cylinder. For those using SRAM shifters we have designed a slick and minimalistic direct mount adaptor.

Mr Brown For years I've been a shimano man, but having recently been approved for a credit card I threw caution to the wind and changed sides to give these a go and needless to say I was not disappointed. When I opened the box I was blown away by the beautiful CNC work and smooth lines of the calipers. I'm no prude, but I don't practice human/bicycle part relationships, however I would probably take these brakes out to dinner. Next the sheer braking force in these puppies is immense, I'm not certain, but I'm pretty sure when you pull the levers the power of this incredible machines doesn't only slow the bike down but actually slows the rotation of the earth slightly. Thanks to the extra olive/barb that comes in the pack the hoses are easy to shorten or internally route (unfortunately the hose doesn't route itself but I don't belive there is any brake on the market that does this yet anyway). The box also contains two more sets of pads, one of them is e bike specific, so I'd exercise caution when fitting to a normal non electronic bike - pull the brake hard enough with these fitted and the Earth could actually stop spinning and plunge us all into the next ice age. Great brakes though, 10/10 would recommend to a friend.
David Best brakes I’ve ever owned. True bite point contact control, easily control modulation, strong braking power.
Mr May-White Can't fault hope v4. Very linear feel, very robust and a quality component. Top service as always from Merlin.
Joyce Best brake ever invented. Fast shipping even though I'm in the US. It came properly packed and fast. I recomend this brake for enduro and DH, even for a trail bike! LOTS of power and durability, very tuneable and doesn't need maintenance at all.
Zac Absolutely stunning brakes, loads of power, comes with metal and organic pads in the box, have made some tweaks to allow less free stroke and removed the lump on the end of the lever. Stunning hope quality makes sram brakes look like they are plastic, expect to have these for a long time.
Frosty Amazing brakes. Went from Shimano Zees to these and the increase in quality is amazing. The Shimanos feel like cheap toys in comparison. Power is excellent on the Hopes and modulation is even better. Merlin also has great service and the shipping was quick. Best price for these brakes around.
Mr Alonzo Best set of brakes I have owned! I have been riding for 10 years and I have used many different brands. Modulation and stopping power is best above all on these set. Will buy another set for my other bike.
Lukasz Previously had the XT M8000. If I compare them to hopes the XT hasn't any modulation and the brake power is poor. Hopes are awesome brakes and they look like jewellery.
Mr Rogers Awesome brakes! Top quality engineering, very adjustable and best modulation of any brake I have owned.
Marcello Hope top-level brake, as usual. Good stopping power, and super lever feeling: you can always get the right braking you need. High quality manufacturing.
johnson Love these brakes power and modulation are top of the game. And of course the cnc'd beauty adds that class to any rig
Mr Slattery So far only a few rides on these brakes. A bit tougher to set up than Shimanos, but plenty of power and much much more modulation. The levers are super adjustable and very nice. FYI, the brakes come with an extra olive, insert, and brass washer out of the box.
Glenn Blake, BC, Canada The Hope V4 brake was super easy to set up, just like the other Hope brakes I've had before: Mini, M4, E4 and X2. I am running the V4 on the front of my all mountain bike and it replaces an E4 caliper. The E4 was good but lacked power on the steeper trails I ride on Vancouver Island. The V4 is very powerful indeed and matched with the Tech 3 master cylinder provides the modulation Hope brakes are renowned for. The V4 was that powerful it took a while to adjust to its power increase over its E4 sibling - I was locking the front wheel up on loose descents! I've run Hope's Mini lever [2003], Tech 3 and for the last couple of years their Race Evo master cylinder. The adjustability of the Tech 3 lever is really unsurpassed by anything else on the market. I like the bite point on my brakes to be just a few mm from the start of the lever movement. With the bite point control I can dial them where I want and on the trail if required. I changed the brake line from the braided one sent to the bike's current braided line that was trimmed to length so I did bleed the brake after fitting the caliper and master cylinder; so I can't comment on whether the factory bleed was great or not. The only thing that let my purchase down was the slow shipping from Merlin to Canada. With the TrakPak service it took 14 working days to arrive from date of despatch. With no option at the checkout for a faster couriered service this was disappointing and could be improved upon greatly. A 4-6 calendar day service would be acceptable.
KJayjay I used Hope brake for many years and then try to use XT and Saint for few years, however once you use hope again especially V4 brake, your won`t regert, best brake ever, powerful stopping power with high QC.
Mr Wong Easy to set up! They give such instant feedback and extreme stopping power. I feel more confident in riding more tough routes. GREAT!
Mr Freer Superb brakes. Easy to set up with great braking power and modulation. Usual Hope quality.
Sam Stunning brakes. After having the original V2's, these are a huge leap in performance. BPC actually works on this version. Have xt brakes on other bike, the difference in lever feel is well documented on the web and as far as I can make out comes down to personal preference between the two. I ran 203mm both ends with the xt's, 180 with the v4's and I am not left lacking in out and out power. The redeveloped master cylinder gives a very neat appearance on the bars compared to the older Moto and tech versions. First time set up took less than 30 minutes including aligning calipers. Included in box is a spare set of sintered pads, I have these in to cope with the winter grime, bed in was quick and power now consistent and huge! These aren't cheap, but ooze quality and have huge power coupled with superb modulation (something the xt's simply can't match)
