With out query, brakes are probably the most vital parts of a motorbike. Ask any aggressive rider what they need out of a brake, and the very first thing most would say is tons of stopping energy. Now ask SRAM what’s up with their new Maven brakes and so they’ll say “Maven is absolutely the strongest brake we’ve ever made.”
The brand new Maven brakes have beefy 4-piston calipers, massive caliper and lever pistons, a re-tuned lever, and new XL brake pads, all of which make them an extremely robust brake. With all that energy, riders can loosen up on squeezing their levers and scale back arm fatigue. After all, sheer energy is not any good with out the flexibility to manage it, so the Professionals will be tuned in varied methods to offer a lighter or extra forceful chew.
SRAM has produced three totally different fashions of the brand new brakes. The Maven Final, Silver, and Bronze. I’ve had the Maven Ultimates on my bike since early this month, so my preliminary impressions are included on this submit. I plan to put in writing a full evaluate later this summer time after much more testing and tuning.
SRAM Maven Brakes:
Let’s begin with some numbers. Most significantly, SRAM says the Professionals produce nearly 50% extra energy than their DH-grade Code brakes. Additionally they say it takes 32% much less power on the lever to match the chew energy of Codes. With gobs of energy, the Maven brakes are appropriate for any sort of driving; DH, eMTB, enduro, or path.
Within the Maven’s press materials, SRAM dove deep into explaining how warmth administration supplies optimum braking energy and management. I’ll describe beneath how a number of the Professionals’ parts assist obtain this…
Calipers:
The Maven calipers are fairly beefy trying, and people 4 huge bolts are there for power! They hold the caliper physique further stiff, decreasing flex and energy losses. All fashions of the calipers use massive pistons, with two 18mm and two 19.5mm in every. The massive pistons provide extra floor space to push on the brand new XL pads the Professionals require. The Professionals’ brake pads are bottom-loading.
As for managing warmth, the Maven calipers are literally designed to not quiet down too shortly. The calipers do take longer to warmth up, however as soon as they do they’ll resist overheating and keep inside an optimum temperature vary longer than different brakes. SRAM says much less temperature variation as you journey interprets into extra constant braking energy.
Maven is Mineral Oil-Primarily based
Surprisingly, the Maven is a mineral oil system. A number of years in the past, SRAM constructed two variations of the identical brake system and examined them back-to-back with each mineral oil and DOT brake fluid. They favored a number of the benefits of mineral oil, notably a longer-lasting setup with much less upkeep. Nonetheless, they needed to overcome one subject: the seals within the calipers.
Conventional mineral oil-compatible seals merely don’t carry out in addition to these designed for DOT brake fluid. The oil-resistant materials they use doesn’t deal with excessive temperature variations in addition to DOT-compatible seals. To resolve this SRAM discovered a brand new proprietary seal materials that’s mineral oil-friendly, however can deal with high-heat conditions and low temperatures.
On the subject of mineral oil, SRAM solely approves the usage of Maxima Mineral Brake Oil (co-developed with SRAM) for the Maven brakes.
Levers:
The Maven brake levers provide an analogous really feel to SRAM’s Code levers. They characteristic the identical pivot level, blade form, tool-free attain adjusters, and (on most fashions) contact level changes. I like how shut the lever physique sits to your handlebar. It’s not a tiny lever, however SRAM tucks it in properly so it doesn’t look too cumbersome. The Maven levers have been designed with SRAM’s ‘stealth structure’ so that they do have a reasonably glossy look for his or her measurement.
SRAM has re-tuned their SwingLink lever and optimized it for the Professionals. The lever’s leverage price modifications by way of the stroke, delivering extra energy the additional you pull. The intention is to offer extra progressive energy supply and stop an ‘on/off’ feeling.
SRAM ensured to match the large caliper pistons with an appropriately sized lever piston. They are saying the ratio between the 2 have to be balanced to offer most stopping energy.
Rotors:
The brand new Professionals don’t require particular rotors. SRAM recommends utilizing their HS2 rotors for probably the most stopping energy and greatest warmth administration, or their Centerline rotors if you happen to’d moderately shave some weight and don’t thoughts a 7% loss in energy. Selecting the right rotor measurement is a part of how one can handle the Maven’s energy supply. SRAM recommends organising the Professionals with the smallest rotors your bike can run, and upsizing from there if wanted.
Apparently, SRAM supplies some directions on find out how to examine your rotors to make sure you’re managing warmth accurately. The very first thing they level out is that warmth isn’t at all times a nasty factor. You want a specific amount of warmth to maintain the brake pads and rotors heat sufficient to seize one another optimally. In the event you run rotors which might be too huge chances are you’ll not generate sufficient warmth as you journey, so smaller rotors may very well present higher seize.
To watch this, SRAM suggests checking for discoloration on the spokes of your rotors. If there are bronzed or brown spots on the high of the spokes, you’re reaching the right warmth ranges. The rotor is getting too scorching if you happen to’re seeing purple or rainbow colours, and you must transfer up a measurement. If there isn’t a coloration, the rotor will not be warming up sufficient and you must go to a smaller measurement. Take a look at the above video for SRAM’s full rationalization.
Brake Pads:
The Professionals’ brake pads are distinctive to the calipers, coming in a brand new XL measurement to offer tons of contact on the rotor. There are two compounds out there; natural and sintered. The natural pads provide a powerful preliminary chew and fewer noise and are perfect for dry circumstances. The sintered pads provide superior sustained warmth resistance and higher efficiency in moist or muddy circumstances.
Brake Mounts:
Brake submit mount brackets are particular to the Professionals. Two sizes can be found; The 20P-1 bracket works for 160/180mm rotors, and the 20P-2 matches 200/220mm. No conical {hardware} is required with these brackets, and 4 chrome steel mounting bolts are included.
Weights:
SRAM did present weights for the Professionals: They listing 362g for the Final mannequin, 371g for Silver, and 369g for Bronze (that’s the rear brake with pads, lever, and an 1800mm hose). My scale confirmed the Ultimates coming in barely greater than claimed, at 350g for the entrance and 371g for the rear. Clearly, these will not be a perfect brake for weight weenies, however they’re not considerably heavier than Codes.
The HS2 rotors are available at 171g/180mm, 203g/200mm, and 270g/220mm. Every matchmaker handlebar clamp weighs 28g.
Bleeding:
Whereas bleeding the Professionals is generally a regular job, there may be one distinctive half to the method – massaging the caliper pistons. In simplified phrases, as soon as the system has been crammed and bled there may be one further step of pumping the pistons out and in over the skinny aspect of the pad spacer, after which pushing them again out earlier than putting in your wheel.
Mannequin Lineup:
There are three fashions of the Maven brakes, and an choice to purchase the Final mannequin with an Professional Package that features every thing you want plus a couple of extras. Under are some key variations between the fashions.
Maven Final Professional Package – $599
The very deluxe Maven Final Professional Package is a restricted run, introductory bundle deal that anybody contemplating the Maven Ultimates ought to undoubtedly leap on! For a similar worth as a entrance/rear combo of Maven Ultimates, the Professional Package provides you a ton of additional elements so you possibly can fine-tune the brakes to your wants, or for various race tracks. As soon as these kits promote out, they’re gone.
The Professional Package consists of each levers and calipers, 4 HS2 rotors (180/200/200/220mm) in a zippered carrying case, rotor bolts, two MMX clamps, two 20P-2 submit mount brackets, two units of sintered brake pads, a set of pre-installed natural pads, and a Professional Bleed Package that features Maxima mineral oil, 4 barbs and 4 olives.
Key specs on the Maven Final brake embrace Ti caliper bolts and Ti lever bolts, and if you will get the Professional Package you’ll get polished lever our bodies. Final however not least, the calipers within the Final Professional Package are available a novel purple splash anodized end.
Maven Final – $300
For the Final, Silver, and Bronze fashions SRAM lists pricing for one brake (entrance or rear). All fashions embrace the caliper and lever, hose, a 20P-2 submit mount bracket with bolts, a barb, an olive, and a matchmaker clamp. Rear brake kits embrace a Bleeding Edge becoming.
The Final mannequin will get Ti caliper and lever bolts. The calipers are available a transparent anodized end.
Maven Silver – $265
The Maven Silver steps right down to chrome steel caliper and lever bolts, and the calipers are anodized in Daring Black.
Maven Bronze – $185
The Maven Bronze options the identical measurement pistons, Bleeding Edge bleed ports, and tool-free attain alter levers because the higher-end fashions, however there are some variations.
The bronze fashions use stamped aluminum caliper our bodies, whereas higher-end fashions are all cast aluminum. Additionally they get chrome steel {hardware}, and a bushing lever pivot as a substitute of a bearing. There isn’t a contact level adjustment on the bronze levers, and the calipers are anodized in Darkish Polar.
When it’s time for replacements, XL natural or sintered brake pads each promote for $27.
The Maven brakes can be out there at SRAM retailers this month.
Preliminary Impressions: Arrange
For preliminary setup, SRAM recommends beginning with the smallest rotors your bike can run! I may really put a 160mm rear rotor on my bike, however my native trails can get fairly steep so I caught with two 180mm rotors.
I’m not a heavy man, and I used to be placing the brakes on my non-electric enduro bike. Anticipating what the Maven Ultimates are able to, SRAM’s North American PR agent Chris Mandell instructed I begin with 180mm rotors and the natural brake pads.
Because of slippery, snowy circumstances, my first take a look at journey was simply an opportunity to begin bedding within the pads. On snowy trails, it was onerous to get a really feel for brand new brakes, however I observed an apparent preliminary chew and it didn’t take far more of a squeeze to lock up a wheel.
On-Path Efficiency:
My subsequent couple of rides have been higher for testing, as I used to be totally on damp dust. I observed a lot much less effort squeezing the levers versus another brake. The Professionals have a stable preliminary chew and the facility comes on shortly. As quickly because the pads contact the rotors you’re feeling braking energy, however you gained’t simply lock up your wheels. Past that, it solely takes a slight squeeze to ramp up ample energy for many brake faucets into corners, and many others. The one time you must put out something near the trouble most brakes require is on steep descents or high-speed sections.
A few of my trails are nonetheless slippery and the Spring dust is a bit slick, so I’m nonetheless having some points with locking up the rear wheel. Feathering the Professionals does take some getting used to; you actually do must loosen up your contact on the lever for mild and mid-level braking, or the Maven’s energy can come on too robust. Even on dust sections of path, I locked up the rear a couple of occasions once I didn’t intend to. I anticipate with a couple of extra rides I’ll adapt to the lighter contact wanted.
As for the levers I like how SRAM caught with their established form. Other than squeezing them extra gently, the Maven levers will provide a well-known really feel to anybody who runs SRAM brakes. Additionally, the matchmaker clamps left my dropper submit distant and shifter in comfy positions.
With only some rides to date, I’ll dive deeper into long-term efficiency and fine-tuning in a full evaluate later this summer time… keep tuned to Bikerumor!
