What an intelligent discussion about the modern state of the hardtail and geometry. It's rare in this industry to find people who put this much thought and intelligence into their bike designs. I shouldn't be surprised, on the first ride it became obvious this bike was designed by someone who knew their stuff. I couldn't agree more with the comments shared in this video. Thanks for pushing the boundaries of modern hardtails, and thanks for designing such fun bikes. The Sirius is special, and I am honored to have been able to test it.
The Sirius S5 is my daily driver MTB. It handles everything Coastal BC can throw at it. I have a lovely FS bike I enjoy riding, but it's just gathering dust because the Sirius is more fun. I tried a Moxie, but went back to the Sirius. Pipedream has really made something special with this frame.
Thats My Bike! - I can confirm that the first ride was awful, like Alan said. Coming from a steeper XC bike, I couldn't get my head round steering tight bends. Now, i'm over it and every other bike feels twitchy and unstable. I use this for everything, and I don't notice the extra weight of the frame. It's just good fun and confident in almost every situation.
I love my Sirius can't see myself on anything else now, plus Alan and the pipedream team are awesome at designing and building some incredible products... 👏😊
I love my Sirius, I built it light(ish) and have two wheelsets, one hand built lightweight ‘XC/Trail’ set and one heavy, wide bike park set, the bike does both perfectly. It almost keeps up with my XC mates on their £8k carbon superbikes on the ups and demolishes them on the downs. Same can be said for the bike park rides, flow trails and natural reds/blacks it does brilliantly with the heavy duty tyres/wheels on. Would I take it down a World Cup DH track or line it up XC racing? Probably not, but everything else inbetween it’s amazing. Having owned various hardcore hardtails with 150mm forks that scared the shit out of me, it’s refreshing to be able to charge almost anything with a nimble 120mm fork. I’m 40 now and I’m jumping more, drifting more and having so much fun on this bike that I wish had one like it 20 years ago. Personally, I found the first ride on it a revelation, it responds amazingly to the load the front, lean it in fast and point your hips and feet where you want to go style of riding. Then the low-ish stack is purely a function of fork, headtube and stem height, so you needn’t worry about that either, with a new 120mm Sid (bought cheaply from pipedream!) it climbs beautifully and still shreds. Just buy one if you like hardtails but don’t want the limitations of traditional XC or Hardcore hardtails! I would only change it if Alan decided to do a titanium version with the same ride quality and geometry! Hint, hint.
I am seriously considering getting this frame and moving over a bunch of parts from my current aggressive hardtail. The game has definitely moved on since I built it back in 2018 and I am here for it!
This actually makes me feel even better about choosing the Moxie. I only want one bike and I'm too in love with hardtails to go full sus yet. The Serius makes perfect sense as a companion to a mid/long travel full sus but I think the Moxie covers more range overall.
Hi pipedream-team, could you please do such a great chat about the ideas and target group of the moxie? The reason I ask is because I was leaning towards the moxie for the last two months, but now with the great hardtailparty review and your talk in this video, there is sadly nothing to find to be able to do a back-to-back comparison between these two hardtails. Thanks in advance!
The geo charts lists this with a 100mm fork at sag, can you share at what sag percentage you chose? Also any possibility you could share the seat tube offset? I'm trying to determine where my seat will end up. I get that bikes can ride different than geo charts but ultimately where my seat is relative to the BB will determine how and where I can ride this. For example a super steep seat angle is great on steep trails but I don't like riding to a trail with one... So Geo charts can be important to make these types of decisions. Thanks!
I would so love it when this bike or the moxie had this tire clearance: 26x4.0", 27.5x2.8-3.8˝ and 29 x 2.1-3.0˝, would be the best of everything totally addaptable. perfect for bikepacking in any climat and fun to take on all the trails on the way. with unlimited options.

This is my next bike. Can't wait.

I was unsure about a few things regarding bike geometry and a quick chat with Alan soon fixed that. 👍
I just ordered a frame to beat the 2022 price rise. Can't wait t ride her.
Full sirius would be great!
Could we get a quick update for the S6?
I’d take this out ahead of a FS bike every ride 😊❤

Cheeky ending!

I would ask why would you buy full sus when hardtail is so good?
I would so love it when this bike or the moxie had this tire clearance: 26x4.0", 27.5x2.8-3.8˝ and 29 x 2.1-3.0˝, would be the best of everything totally addaptable. perfect for bikepacking in any climat and fun to take on all the trails on the way. with unlimited options.
so what your saying is hard tail for hard boys and soft tail for sissys? ;) ?
