Gryphon Mk 3 frameset

Sublime ride - practical fittings - versatile adventure.

Singular was at the vanguard of the current era of big wheel, drop handlebar off-road bikes. Originally released in 2008, the Gryphon was among the first production drop-bar frames with 29" tyre clearance and disc brakes designed for off-road use.

It became a cult favourite. More people came to appreciate the comfort and versatility of drop bars with the alchemistic pairing of big fat 29″ rubber. Drawing upon and further evolving the traditions of the legendary bikes of Charlie Cunningham and more contemporaneously Matt Chester, the Gryphon foreshadowed the advent of ‘gravel’ bikes. To the best of our knowledge, the Gryphon was the first production 29″ wheeled, disc braked, steel mountain bike frameset designed for use with a drop handlebar.

The Gryphon has returned, updated with even more tyre clearance, thru axles and flat mount brakes – but retaining the fabled smooth ride and lively handling of its predecessors.

Available in M, L & XL sizes – in a lovely muted khaki (RAL 7034) with a simple Singular logo in ivory. 

We utilise a size specific selection of Taiwan made custom drawn triple butted heat treated 4130 Cro-Mo tubing. That means larger frames get beefier tubes, and smaller frames still ride nice and smooth with smaller riders.

* Tyre clearance at the rear is dependent on a few factors - exact tyre being used, rim width, front chainline, number of gears, size of lowest gear, ebb position - so it is difficult to be completely definitive - but a 29x3" tyre can be used with most single ring MTB cranks. NB. road or gravel width cranks will not fit this frame.
