Pipedream Cycles have unveiled the Pipedream Skookum 29er - a big-wheeled version of the Sirius which will be available in both steel and titanium incarnations.

The Skookum shares a number of the features found on its sibling, including a tapered headtube and sliding dropouts, which can accommodate a singlespeed or derailleur setup, and which allow riders to tune the wheelbase length. The drive-side dropout also has a coupling for a belt-drive system.

Pipedream expect most riders to run a 80-100mm fork, but the frame can support a fork up to 120mm. A 30.9mm seatpost diameter means the frame can be used with a dropper post, while cables are routed underneath the bottom bracket.

The gusset-free steel frame, which is made from Reynolds 853 DZB tubing, will cost £395, while the titanium version will set you back £989. Both are available in 16in, 18in and 20in sizes.
