First Look - Pipedream Sirius and Scion Steel Hardtails
3 January 2013 | By AngusMcIntoshPipedream Cycles are delighted to introduce the latest 2013 Sirius and Scion, British Steel Hard Tails. The bikes have landed now and we are taking orders from both customers and dealers.
The Sirius 853.
The first incarnation of the Sirius used ‘No Hype, Just Pype’ – a custom drawn, heat treated, double butted 4130 CrMo with a strength comparable to Reynolds 631. It was and is more than strong enough for it’s intended use. However, our US and Japanese distributors wanted a branded tubeset which is why we built the frame in R631 for their markets.
It was 5 more years before our Sirius frame had an upgrade and frankly, it was a challenge to figure out what to do. There were reasons we made the choices we did back then and we confidently stood by them. Tubing choice, geometry, intended usage were all carefully considered after considerable research, riding and prototype development.
Why the changes? Perception is a powerful thing and is often what shapes our choices. Reynolds 853 (among few others) justifiably has a high reputation, backed up by technology, race-results and heritage. It’s proven. Component technology has made some big advances – as has the skill level of the rider – and we know that a well designed hardtail can take the fight to the trail as well as any short/mid-travel full suspension frame. The hardtail is here to stay so why not build it with the best materials available – it’s going to be around for a long time.
As a final note, the sliding dropouts offer more than just singlespeed capability, 650B fit fine and offer yet another wheel choice.
The Pipedream Scion 853.
With our acclaimed “point and pedal” geometry, our frames are built by some of the best builders in the industry.
As we’ve already said, this frame is the ‘Sirius for the single minded’ – the geared crowd who want a high performance, lively frame with no-compromises so Reynolds 853 features once again.
The main design elements of the award-winning Sirius have been retained with one major exception – the dropouts. We’ve opted for a cowled design to give us a large weld area for the stays and also included a replaceable gear hanger, just in case. One other subtle change is slimmer seat stays. These two changes shave weight (without compromising strength) and give you the bike you’ve been looking for.
Winter steel hardtail anyone? We'll soon be replenishing stock of the lovely Scion R853. Sharing the same award winning geometry as our flagship Sirius R853, the Scion will be available in 2 new colours - pearlescent Midnight Blue and pearlescent Flame Orange. If you want a test ride on one before buying then let us know and we can meet you at your local trail. Email us on [email protected] or give us a call. The Scion is now available as a complete bike too and can be supplied with the X-Fusion Hilo dropper post as pictured.
