Pipedream Updates Winter Hardtails w/ Reynolds 853 Steel Tubing, Sliding Dropouts & 650B

2013 Pipedream Sirius 650B hardtail mountain bike with Reynolds 853 steel tubing

Pipedream’s Sirius hardtail mountain bike has been around unchanged for about five years. But when it came time to update it, they were hesitant to fiddle too much. Afterall, they liked it quite a bit the way it was, so the changes were cautious, but not subtle.

The original model was built with 4130 chromoly steel. Then they upgraded it to Reynolds 631. Now, for 2013, it gets a new premium Reynolds 853 steel tube set. They also added sliding dropouts capable of moving far enough back to fit 650B wheels in the normally 26″ frame. Which also lets you run it singlespeed. Other tweaks are minor and set it up for modern 2×10 drivetrains and stronger forks, but the character remains the same.

There’s also the updated all-mountain hardtail Scion, which gets a few changes to the rear end…

Also using Reynolds 853 steel tubing, the Scion is a geared-only all-mountain style hardtail. For 2013, they gave it beefier cowled dropouts for more weldable contact area on the stays, and the seatstays were thinned a bit for a smoother ride. The changes also dropped a few grams overall.

Frame is £349, and complete bikes are available built as shown with the X-Fusion HiLo dropper post or in other configurations. New colors include a pearl midnight blue and pearl flame orange.

  1. I have looked at a fair number of steel hardtails recently, and am wondering why most of them don’t have tapered or oversized head tubes. Maybe a cost issue?

  2. Sweet! There is a soft spot in my heart for steel AM hardtail 26ers.

    1 1/8 headtubes work fine. The only issue I see are fork compatibility 5 years down the road.

  3. Is it me, or are the geometry specs and/or the visual shape of the geometry a bit quirky?

    I went on their site and the numbers aren’t crazy, but something just looks wrong…. Just me?

  4. The new Sirius green colour is a lovely. Just to add it also has a tapered headtube, the stock image looks like the older model.
