The long-awaited and outrageously overdue Peregrine Mk4 is due to land in both our US and UK locations in the final week of May - and will start shipping in the first week of June. Stock is rather limited, so if you'd like to secure one please make an order on this page. 

A classic silhouette for a modern gravel bike - full 29" tyres, the finest steel tubing and all the fittings you need whether touring or commuting.  

Classic design - the Peregrine utilises a lugged construction of frame and fork - providing both strength and a classic look. 

Slender steel - slim tubing provides not just a classic aesthetic, but gives a supremely smooth ride. The Peregrine is no noodle though, load it up and it feels solid and stable. 

Big clearance - with space for up to 29×2.2" (700×55) tyres and full length mudguards.

Eccentricity is good - the Peregrine has an eccentric bottom bracket shell. The primary benefit of this is for tensioning single cog drivetrains - whether fixed gear, singlespeed or an internally geared hub. However it is also really useful for fine tuning the bottom bracket height when using different size wheels and tyres - for instance switching between 700c and 650b wheels. 

Keep 'em outside - All cables are routed external to the frame with neat modular cable guides. This makes maintenance and parts-swapping a breeze.

The Peregrine was the second frameset designed under the Singular brand – with the first prototypes landing in May 2007. I’d already been a big proponent of 29” wheels – launching the Swift in ‘06. The concept of the Peregrine was to take the function of those big wheels and put them in a classically styled, lugged construction frame – adding disc brakes and the ability to use current componentry. That brief hasn’t changed in the 18 years which have since passed – bringing with them a whole raft of ‘gravel’ bikes – a wider audience now coming to appreciate the wonders of drop bars and fat tyres for tackling varied terrain.

Frame & fork price £1200 (including UK VAT)

Peregrine Tech and FAQ

• The EBB set screws should be torqued to a maximum of 6Nm or it may deform the shell and insert. The EBB should be covered with a thin coat of grease and maintained periodically by removing, cleaning and re-greasing the insert and bolts. 
• The seat binder bolt should be torqued to 8-10Nm. If this is insufficient to prevent seat post slippage please contact us. Some frames were shipped with an incorrect spec bolt which bottoms out before the seat post is fully tight. Please contact us for a replacement if this is the case. 
• The derailleur hanger is designed to only be loosely held by the mounting bolt. The hanger is tightened to the frame by tightening the thru axle so that it is clamped and supported properly in the dropout and not by the hanger retaining bolt. Many thru axle frames have a similar floating axle retention nut mechanism. 
• The frame and fork are fully tested and compliant with ISO standards for touring bicycles. Used as intended, it is warranted for life for the original owner. The frameset is not intended for technical off road riding or jumping.
