Pipedream Release New Sirius Hardtail

Nov 11, 2020

PRESS RELEASE: Pipedream

Pipedream have announced today that the Sirius hardtail is now in stock and ready for the trails.

The Sirius is a short travel, steel hardtail ready to turn the volume up on local trails. It's made to allow riders to sharpen up and push the pedals hard. The bike is optimized for a 120mm fork with a 65-degree head tube angle. It can accommodate a 100-130mm fork and is made for long miles and serious terrain. It's made to the high standards of Pipedream and represents their ultimate in steel hardtail performance.

Local loops, trail centers, and epic XC adventures, the Sirius is a blank canvas ready to be built however riders see fit. With more riders venturing from their front door to hit the trails in the times of lockdown, the Sirius, with Pipedream's geometry, can be a rider's short-travel, rowdy, hardtail companion to carry them through winter with a smile.


Geometry

Pipedream's D.O.G. or, Drop Optimized Geometry, is their philosophy for bike design. Pipedream claim that when things get exciting, their bikes will keep riders on track due to their long, low, and slack geometry they've been utilizing for some time now. There is a 65-degree head angle, 77.5-degree seat angle, and 465mm of reach in a size Long.


Steel

A custom tubeset is used to build the Sirius. The tubing is designed specifically for the frame so that the custom butt profiles are optimized for strength and performance, negating the need for external reinforcement, according to Pipedream. This delivers the clean aesthetic Pipedream are known for and enhances the properties of the tubing with no gussets.

There is also a rigid fork on the way, especially designed for the Sirius to turn it into an ultimate bikepacking and adventure bike. There are also flat-mount dropouts coming so riders can install drop bars, if they desire.


The bike is available in three sizes - longish, long, and longer. Colors available are Silver Fox, Starry Night, and Vintage Green.

The Sirius sells for £649.00 and more information can be found at pipedreamcycles.com

 Are those stack numbers correct?

586mm of stack across all sizes? Thats a solid 40mm-60mm or so lower than most bikes with comparable reach (Honzo ESD with a reach 5mm longer, has 643mm stack).

What are taller people supposed to do, install a 100mm riser bar?

They weren't kidding when they meant "low".

 buy a different bike. there are plenty with tall headtubes. use a tall headset topcap, stem and or handlebar, use a relatively tall fork. use external headset cups . it's not that hard. one thing you cant do is make the headtube shorter.
  • 2 2
 @getsomesy: But the problem is no one above 160cm needs such a short top tube. Except XC racing, which this bike is not designed for.
My take is that is a simple marketing trick to specify long reach. The real reach for any person will me MUCH shorter than this.
So, this is a short, expensive bike, which will look like sh*t with 5cm of spacers.

 @lkubica: its neither short nor expensive (thats just how much a quality steelframe costs these days, and quality is top notch unless you need an 853 sticker). Stack is too small that is true. Actually i wonder how the stated stack is even possible. It has 29er wheels a 105mm headtube, 525 forks and one external headsetcup. the moxie has the same setup and sits at 642mm with a 562mm fork and a slacker headangle. on paper the stack of the sirius should be more like 605mm-610mm.

Nevertheless i think the universal 105 mm headtube is a cost cutting measure and is not ideal performance wise. It should at least be 120 -130 on the big one.

 @getsomesy:

Not saying anything bad about it. And you're right, all frames don't have to appeal to everyone.

I was just pointing out that it seems pretty uncommon to have the stack height across all frame sizes be the same. Maybe its for the drop bars though. I'm no expert on gravel/road bike frames.

For kicks, I just looked at a couple of cross country bikes because admittedly, the Honzo ESD is on the aggressive end of the spectrum for hardtails. I figured a race cross country bike should have pretty low stack, so I looked at the Trek Procaliber, and Specialized Epic cross country hardtails.

As it turns out, 586mm of stack is about the size of the Trek Procaliber, and smaller than the Specialized Epic cross country hardtails in size small. The larges of the same frames seem to run ~605-625mm or thereabouts. So it does seem remarkably short in stack height, even compared to some of the "raciest" bikes in mountain biking.

 are you kidding me I think its sick that the industry is bringing back hardtails. Bikes are getiing bigger, longer and squishier, so its cool to see some good ol hardtails coming back. This is where mtb started, man. I love squishy bikes but damn hardtails always humble me, and remind me how to properly ride a bike.

 I sold my YT Jeffsy after building a Ragley Mmmbop. Also just built a custom Marino and have one more Mariano on order. A slack hardtail is a blast. Fewer pedal strikes, you know what the back is going to do and so much fun ripping down a Rocky trail. It will make you faster when you get on a good FS bike also.

 Such a good looking frame! It would make a great single speed winter time ripper

 Looks nice and I'm happy Moxie is offering a frame that's focused more on cross-country as opposed to super slack enduros and trail bikes. Many of us are very happy exploring and riding forest service roads, marked trails and even gravel roads. My biggest quibble about the Sirius is the lack of water bosses on the seat tube or on the underside of the downtube. The frame should really come with the option of carrying two water bottles.
  • 2 1
 Only problem is that bottle bosses can limit seat post insertion depth and thus dropper length
  • 2 0
 @overconfident: I wouldn't say its a problem. You don't have to use a dropper post at all.

 I like the adjustable chain stay. I'm not sure if the long chain stay crew is happy with "only" 441mm, but still nice that it's not one size fits all.

 It also lets you run SS. It seems a lot of hardtail designers overlook this market segment, which makes it hard to find good options if you prefer to ride singlespeed
  • 1 0
 @shinook: I don't think it is a matter of "overlooking". It is more a matter of, are they willing to cater to those too? Singlespeed does introduce some additional challenges and putting effort (hence money) into that doesn't add any value to those who would run a rear mech anyway. So it depends on the market. Here they decided that a bike with a rigid or 100mm travel fork would be interesting for singlespeed (or geared hub) riders too, but then the number of people who would do that on their Moxie is too small to bother with. Yet you may still find people who'd be bummed that this one can't work with belt drive (for singlespeed, Rohloff or Alfine hubs). And yet again it isn't a matter of overlooking. Just that catering to those would introduce some new challenges.

 Would be awesome to see more hardtails running all the cables on the top/side of the downtube instead of breaking them up. Would be a much cleaner look.
  • 1 0
 I'm not sure there. If the chainstay and top tube are more aligned, I like how the cable/hose can accentuate that. This is a picture of my bike when I just assembled it (the saddle was only high so that the workstand could clamp it, I usually run it nearly slammed):
www.pinkbike.com/photo/15893339
My rear brake hose is white too now and I think it accentuates these lines even better.

Technically, I prefer the top tube routing too as I feel air bubbles in the rear brake travel upwards more easily and end up in the reservoir. Whereas if the hose makes a bend and you get a local high point, air settles there so it takes more conscious effort to chase them away. How much of an issue this is obviously depends on your brakes and how often you're willing to service them.

 Funny, i recently put a 110mm fork on my Nordest Bardino, the Numbers are quite close. It rides nicely and is way enough for the local trails, although most Santa Cruz owners think differently.

 Good luck with that. As IIRC the Sirius has had many versions and go back years. This is in fact another version of a Sirius that came out a few years ago and I'd have to check with the Pipedream guys but there's a Sirius model going back at least ten years.

 Would there even be an issue if the names are just different, as it is here? (Sirrus vs Sirius)

 That stack = fake reach.... After i got my Banshee Paradox i understood how important sufficient stack is (for me at least). When i want to have my but in the air, I take a ride with my CX.

 5-6 pounds depending on frame size probably. Should be really close to the Moxie hardtail frame. My Moxie ended up a little over 31 pounds with 27.5 wheels and 140mm fork.

 @Mieszko42: Already on our website Smile all our pricing on build kits includes shipping, as do our frames. If you're able to pick up locally in West Kelowna we offer a local's discount as it saves us shipping. We're hoping to be shipping frames, and build kits by a month from now at the latest, but we're at the mercy of shipping companies at the moment.

 No mention of wheel size.

Is 27.5” dead?
  • 1 0
 It has sliding dropouts the same as the Moxie, which can run both wheel sizes. Maybe you can run both with this? (sorry, I'm too lazy to check their website).

 That HA looks slacker than 65 to me.
  • 2 0
 Unlike Cotic, I suppose Pipedream publishes the unsprung geometry (like most brands do). It seems challenging to argue angles over pictures on the internet, but I'd say it isn't far off 65deg. My hardtail has a 63deg HA (unsprung, 120mm travel fork) and in the picture it does indeed seem slightly slacker than this one. It may be the less sloping top tube (and the junction between top tube and head tube) of the Pipedream that might give a different impression?

  • 2 4
 I like it, but could use a steeper headtube angle. Does anyone know of a HT with a 63 degree or slacker headtube? my DH bike is 63, and would like something to at least match that.

 Grim Donut HT should be the next project for Mike L.
  • 6 0
 Please understand that DS bikes, sag both ends, while on a HT, only the front end SAGs, meaning, 65º unsaged, will be like between 66,01º and 66.31º
