Pipedream Sirius S5 | Everything You Need to Know.

The Pipedream Sirius S5 has landed and sits below the Moxie for all your steel-framed trail and adventure riding requirements.

Designed as the ultimate, do-it-all hardtail, Pipedream’s new Sirius S5 blends progressive trail geometry with custom steel tubing all designed around a 120mm fork for maximum good times on the trail.

The Sirius sits between its siblings, ALICE and Moxie, to provide the ultimate, do-it-all steel hardtail. Designed around a 120mm fork, but taking anything from 110mm to 130mm, there’s even a rigid fork in the works for those who want to hammer out those bike packing miles and aren’t fussed about suspension. You can still built it up for a rowdy winter companion though.

You get a custom-butted CroMo frame that will take up to29 x 2.6″ or 27.5 x 2.8″ making it a good option for the winter months when mud clearance becomes a serious consideration.

Built On Baggies


Available as a frame-only currently, the Pipedream Sirius S5 comes in three sizes, Longish, Long and Longer with some suitably long reach numbers and sensibly short seat tubes all in Pipedream’s custom butted steel tubing.

On the Long frame, you get a 65 degree head angle, and a 77.5 degree seat tube angle, a roomy reach at 465mm combined with a 420mm seat post. Chainstays are adjustable between 425 and 441mm, with the wheelbase changing between 1175 and 1191mm.

Frames come in three colours, Silver Fox, Starry Night and Vintage Green, and cost £649.99.
