First Look: Cube's New TWO15 DH Bikes

Oct 5, 2020
by Dan Roberts  

Despite DH races being a bit thin on the ground, we've seen a few new DH bikes pop up this year, and just around the corner we have the biggest race of the year, the World Championships in Leogang.

Ready for that event, but not all that much of a secret if you're an eagle eyed DH fan, is the launch of the new Cube TWO15. There are two separate version for 2021, giving Cube the potential to focus each bike in more closely on its specific job.

The HPC version is squarely aimed at DH racing and was informed quite heavily from the racers' feedback on the old bike. It's also Cube's first foray into a composite DH bike. The HPA version on the other hand caters to the park rats and bike park crew, perhaps more content with squaring off turns and avoiding the pressure police than chasing tenths of a second.


The HPC is the DH race bike of the TWO15 brothers and goes for this with a 29" wheel only setup.

The main frame and rocker link are made from carbon fiber composite. Not a first all together for Cube, but it's first composite DH frame for the company. The chain stay and seat stay of the frame use 6061-T6 aluminum. Overall frame weight is 3.3kg for a size M.

Carrying on from their previous frame, the shock is flipped, with the piggy back end of the shock mounted to the main frame and was done in an attempt to keep the unsprung mass as low as possible.

TWO15 HPC 29 At A Glance
• Wheel Size: 29"
• Carbon fiber composite mainframe & rocker link, aluminum chainstay and seatstay
• 201mm travel
• 63.8° head angle
• 463mm reach (size L)
• 445mm chain stay
• Weight: 34.83 lb / 15.8 kg (claimed HPC SLT version, size M)
• Price: SLT €5,999, SL €4,699
Cube sought to keep the maintenance of the bike a little easier and skipped the hidden hardware that can be found on some of their other bikes. All cable routing is internal and the fork bumpers on the main frame double up as the cable entry.

There's a 203mm post mount for the brake and an array of stuck on protection from the down tube to chainstay and heel rub areas to keep the bike quiet and more resistant to wear from riding.

Geometry, Sizing & Adjustability

As is the case with both versions of the new TWO15, it's available in sizes M to XL. For the HPC version that sees slightly longer reaches ranging from 443mm to 490mm. That's then paired to a 445mm chain stay on all sizes and a -27.5mm BB drop, giving a BB height of around 343mm.

The stock head angle is 63.8°, but can be adjusted by 0.5° by the use of some adjustable headset cups. German brand Across was drafted in to do the cups which are made from plastic and don't actually press into the frame, the idea being that you can loosen the fork crowns and turn the cups 180° fairly easily. The cups include some small tabs to apparently stop them rotating during use.

Cube stated that they preferred to have just a head angle adjustment over the common flip chip somewhere in the suspension system to avoid changing the whole bike geometry in one go. The change in head angle also gives a smidge of BB height change too at 1.5mm.


The new TWO15 retains the Horst pivot rocker link layout of the previous bike and also retains the imperial length shock.

The HPC is built around a 241mm x 76mm stroke shock, or 9.5" x 3" to be imperially correct. This allowed Cube to pack a tiny bit more stroke into a shorter eye to eye than the metric shock version, drop the standover of the frame and package a shorter shock in the frame without the need for a side loading trunnion mount.

2021 Cube TWO15 Leverage Ratio
2021 Cube TWO15 Anti-Squat
Leverage ratio left and anti-squat right. Blue is the new bike and green is the old bike.

Cube was given the green light from Fox that the shocks would be available for the foreseeable future and it's the company's DHX2 that the whole bike is designed around. Having said that, the Float X2 will also fit. So too with other brands shocks as long as you can get an imperial version. That shock compatibility is he biggest downside of going with an imperial length.

The new bike's kinematics see a drastically upped progression to 43%, with a much higher starting leverage ratio of 3.6 dropping all the way to 2.05.

Anti-squat also sees an increase, with around 140% anti-squat at sag with a 34/18T gear combination and overall higher percentages throughout travel. The bike's anti-rise sits at around 60% throughout the whole travel and is also an increase over the old bike.

2021 Cube TWO15 Anti-Rise
2021 Cube TWO15 Pedal Kickback
Anti-rise left and pedal kickback right. Blue is the new bike and green is the old bike.

Cube knew the up in anti-squat would also bring an increase in pedal kickback degrees, but also knew the topic is deeper than just a graph and the number of times it actually affects the rider is different to what most people think or believe.

Lastly, the axle path was wiggled to give a slight bit more rearward trajectory, only 2mm, but mainly to overall be a bit closer to vertical around sag.

Options, Price & Availability

The HPC version of the TWO15 is split into two models, the SLT and SL, both available now.

The SLT version is a replica of the team bikes and uses a Fox 40 Factory fork and DHX2 Factory shock, SRAM X01 DH drivetrain with Race Face Sixc cranks, Magura MT7 brakes, Race Face Atlas wheels with Schwalbe Magic Mary and Big Betty combo with a Super Gravity casing. Price is €5,999 and the claimed weight is 15.8kg or 34.86lbs.

The SL version uses a Fox 40 Performance fork and DHX2 Performance shock, SRAM GX DH drivetrain with Race Face Atlas cranks, Magura MT5 brakes, Answer ATAC DH wheels with Shwalbe Magic Mary Big Betty combo with a Super Gravity casing. Price is €3,699 and claimed weight is 16.6kg or 36.6lbs.

2021 Cube TWO15


The HPA carries over a lot of the engineering and design found in the HPC version and actually uses the same composite rocker link. The rest of the frame is made from aluminum and frame weight is claimed to be 3.8kg.

With not everyone wanting every run they do on a DH bike to be a full on race run, Cube sought to cater to the crowd looking to get their fun from a slightly different motivation, as well as riders looking for a less expensive, 27.5" wheeled option.

TWO15 HPA 27.5 At A Glance
• Wheel Size: 27.5"
• Aluminum main frame, chain stay & seat stay, carbon fiber composite rocker link
• 200mm travel
• 63° head angle
• 455mm reach (size L)
• 430mm chainstay
• Weight: 37.26 lb / 16.9 kg (Race version)
• Price: Race €2,999, Pro €2,499

The HPA is designed around 27.5" wheels only and sees some geometry changes to also help with the more bike park focus on fun and games.

Geometry, Sizing, Adjustability & Suspension

M, L and XL sizes are available with slightly shorter reaches compared to the HPC race bike. Reach spans 435mm to 475mm and is paired with a shorter 430mm chainstay length.

The HPA also uses a metric 250 x 75mm shock to enable Cube to use other shock manufacturers and hit the necessary price points while also opening up the bike to fitting shocks from all brands.

It uses the same plastic adjustable headset cups with a stock head angle of 63° that can be adjusted down to 62.5°.

The smaller wheels also drive a smaller BB drop of -8mm giving a BB height of around 346mm, which is altered by 1.5mm with the head angle change.

2021 Cube TWO15 HPA Pro

Options, Price & Availability

The HPA version is also split into two models, the Race and Pro, available very shortly.

The Race version uses a Marzocchi Bomber 58 fork and Bomber CR shock, SRAM GX DH drivetrain with Race Face Atlas cranks, Magura MT5 brakes, Answer ATAC wheels with Schwalbe Magic Mary and Big Betty combo but in a Super Trail casing. Price is €2,999 and the claimed weight is 16.9kg or 37.26lbs.

The Pro version uses an X-Fusion RV1 HLR fork and H3C shock, SRAM GX DH drivetrain with Race Face Chester cranks, Magura MT Thirty brakes, Answer ATAC DH wheels with Shcwalbe Magic Mary Big Betty combo but in a Super Trail casing. Price is €2,499 and claimed weight is 17.7kg or 39.02lbs.

 WTF are cube smoking....

Flipped imperial shock to "reduce unsprung mass" but then alloy rear end....
Imperial to "Squeeze extra travel out of a given eye to eye" they... have heard of trunnion right? plus bushing on a suspension design with so much upper mount rotation is sacrificing some sensitivity.
Let alone the non trunnion, metric right side up shock on the alloy one. So you get neither the compact stroke to length ratio nor the "unsprung mass reduction"... was it so hard to use trunnion?

AND then f*cking SUPER TRAIL on a "bike park oriented bike".... Not even super gravity, let alone downhill?

Plastic headset cups... no thanks..
  • 9 2
 That's why it starts at €2500 vat
  • 1 1
 They flip it for unsprung mass more than to keep it low in the frame.
  • 5 2
 @BikesBoatsNJeeps: and then they bolt on a heavy alloy rear end, with a heavy wheel, with a heavy tire filled with heavy sealant, and then bolt on heavy brake, chain, derailleur, cassette....

Would you rather be able to choose whatever shock you like, potentially lower standover and stiffer rear end with easer access to adjusters and less friction or save 250 grams or whatever out of 3-4kg of unspung weight and lower centre of gravity a couple millimetres
  • 19 1
 Trunnion shocks seem to have lower reliability and bring with them their own problems, so I don't mind them using normal mounts. Alloy rear end is not unusual because of rock strikes and other hits. Everybody complains about carbon fragility there, so a lighter carbon front end with an aluminium back end is also a sensible choice. Light weight tires are unfortunate. They usually do this to save weight on the spec sheet. They are easily replaced though. The same goes for the bushings. They can always be replaced with bearings if you care about the last couple percent of sensibility. Bushings are more affordable and often reliable though and contribute to the low MSRP starting prices. Plastic headset cups seem strange. No idea what durability will be like. Not all plastics are equal.
  • 4 0
 @BikesBoatsNJeeps: Flipping the shock puts the heavy steel coil higher up.
  • 3 2
 @Mac1987: why would a trunnion mount shock be any less reliable than it's standard metric counterpart? If anything, the bearings in a trunnion frame should outlast the du bushings or aftermarket needle bearings in a standard shock eyelet, neither of which are very durable.
  • 2 0
 @Mac1987: I agree at all, it's a bike to be beaten hard and with easy mantainance. I'd like to try one even if downhill isn't my daily lsunch!
  • 7 1
 @thegoodflow: the bearings on a trunnion mount are not the part that wears. The wider spacing transfers more load to the shock body or damper shaft. It's not a secret, just a compromise.
  • 2 2
 @PhillipJ: Trunnion mount isn't much wider than the spacers they're using on the traditional mount. Maybe they just need to build a better rocker. Side-loading of shocks is rarely a problem on 1st-class lever rockers like this, much more often seen when the shock is directly connected to the seatstay (like many Canyons or an older Ibis).
  • 3 1
 @bishopsmike: the shock body is far heavier than the spring perch end, reducing unsprung mass therefore increasing suspension sensitivity. How much? Not much at all. However every time you cycle the rear suspension you have to accelerate and decelerate the shock. If the spring perch end weighs half as much as the shock body then you would increase sensitivity. I'm not saying that it's a noticeable difference or drastic improvement considered the mass of the entire rear end, but it has to be some improvement. The heavy end of the shock is now sprung mass. As far as the spring outweighing the shock body, maybe but my guess is that the center of gravity of the entire shock is biased towards the shock body since it extends though at least some of the spring.

 You are lucky to know everything better than their engineers. The bike looks good, does it work well? 99% sure it works well enough for you never to reach its limits. I don't understand why there is always someone to criticize any new bike... Even more when the top spec carbon DH bike is quite affordable
  • 5 1
 @pasteque51: it's true, Trunnion shocks react badly to side loads.

I've killed three already in two different frames.

 @pasteque51: so is every other brand's engineers, like almost every single othe brand. How do you think cube make things so affordable

 @BikesBoatsNJeeps: Yep which is far offset by the lack of bearings in the shock end
  • 1 0
 What would happen if we just flipped the shock around?
  • 1 0
 @PhillipJ: but the du bushing on a standard shock is the part that wears, frequently. And no shock, trunnion or otherwise, is immune from premature wear induced by torsional or lateral loads if the frame is poorly designed with flexy linkages.

 To be fair, cables aren't fancy hardware. They probably used boring standard cables.
On a serious note: I'd have loved the Canyon solution, with a protection plate covering the cables. Simple and elegant.

 I would like some more information on the "plastic" headcups. The cube site refers to them as "fibre".

Also whilst it's cool seeing magura's come stock on a bike I would have thought shimano 6/7120 might be better suited. It's been a while since I've ridden magura. Do they still use a proprietary fluid? Hopefully ebike development has had a positive impact on their performance.
  • 11 4
 They use mineral oil like they always have. Best brakes on the market.
  • 2 1
 @spaceofades: "Royal blood": Blue mineral Oil.
  • 8 0
 The cups will probably be either pa6 gf30, pa66 gf30 or pc gf15. First two are nylon with glass fibre 30% by weight, the second is polycarbonate with 15% glass fibre. Both are incredibly strong (pretty much every professional grade power tool is made of one of the 3) and in some instances probably better than aluminium.
  • 4 0
 They never used proprietary fluid for as long as I can remember. Always has been royal blood, which is just miner oil and can even be mixed with any other mineral oil without any problems. Also, the MT series are the best brake I've ever used.

 Ok - it is so overused , comparing bikes to the Trek Session, however when it comes time for the "induction to DH bike hall of fame" surely the original Trek Session ( alloy one ) needs to be a first ballot hall of fame'r, right next to the Iron Horse Sunday and SC V10. I mean let's be real. It started a revolution of light weight , proper geo , ridable DH bikes with a simple formula/platform. Not actually revolutionary (ok through the rear axle as opposed to chainstay/seatstay ) .

 I'm sure I'm not the only one here who has reached an age and level of professional accomplishment that I would wish not to be referred to as a "park rat". I prefer the term "park enthusiast". On a more serious note, the puns at the top of this thread are just stellar.

Every now and then I read the comment - "I bought 29 because I like new products but now I returned to 27.5", the bike is agile, accelerates easier - 29 is annoying, brake pads fell faster, I had to change the brakes to the strongest on the market + the best brake pads + 225mm discs - summing up 29 = more weight, less agility, less precise driving through a longer front shock absorber, aching hands with the need to use more force, higher costs - more expensive tires, more expensive brakes, more expensive brake pads, more expensive wheels, in the eyes of others you are those who fell for it and believe in everything new must be better and probably drives a new Skoda instead of a used car from a premium class. Well, then new standards sell the fastest, so why not. Loic Bruni doesn't like 29 well either, but he had to put the wheel on and put it on only the front.

63.3 and 63.8, which puts it squarely among all the other modern race bikes out there. The 27.5" version being even slacker. Did I miss something?
Commencal has the exact same number if I remember correctly.
  • 2 1
 @Loki87: Commencal has a 63.8 HA on the supreme 29, but the mix wheeled bike has a 62.5° HA in size large. Yes there are bikes with steep HA, but others are slacker. However, head angle alone is not really something too meaningful (also given it can be changed by sliding the stanction), but if you consider a shortish reach in size L, a shortish rear end, an over 63° head angle and the consequently wheelbase lenght, the geometry is on the conservative side IMO. Does it ride poorly? Most definitely not, but I thought they would have made a different bike. I might be wrong, this is just my opinion. Dh bikes are only slowly converging as far as geometry and fitment go so this topic is up for debate I guess
  • 1 0
 No it's retro.
  • 1 0
 Not sure I would consider the reach numbers small when the stack is 654mm. Is there a calculator out there where you can plug in head angle, reach, and stack in order to have an apples to apples comparison of reach? Head angle would only be needed to find the ratio of change between reach/stack.
  • 2 3
 How does it climb? No water bottle mount ? Pass.
