Design Notes

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.

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. The maximum recommended combined rider and luggage weight of 120kg/264lbs

Big clearance - with space for up to 29×2.2" (700×55) tyres and full length mudguards. However, the Peregrine also rides nicely with skinnier 700c tyres - down to around 38mm would be a minimum recommended size.

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. A fundamental premise in my design is to keep bikes practical, user serviceable, and long-lived.

Beautiful and Functional

"After my Titanium do-everything bike finally succumbed to a cracked chainstay, I started the hunt for a worthy successor. I wanted something with more tyre clearance, mounts for everything, classic looks and the potential to outlast even the 80,000km of the previous bike. The Peregrine ticks all the boxes. It's not light, but that wasn't the point. The ride quality is super smooth, particularly while shod with 50mm tyres under massive mudguards. A bike to go anywhere in all conditions, whilst turning heads in the process!"

John (5/5)

classic style and modern performance

"I searched for a long time for my ideal bike - a Rivendell Atlantis with disc brakes - and finally I found it! The Peregrine has that timeless classic lugged style - but fitment for modern components - disc brakes and thru axle hubs. It's just about perfect for me in every way, I've barely ridden any of my several other bikse since I got it."

Love my peregrine

"Ride it on my commute daily, absolutely love it always feels fast and comfy. Have ridden single speed and geared super easy to change over what with the bottom bracket adjustment. Just super"

Wow. . . just amazing

"My Peregrine is my second Singular - after a summer shredding on my SS Swift and a trip to Italy to expose the shortcomings of my gravel bike, I took the opportunity to upgrade to a Peregrine. The Peregrine is drop dead gorgeous in the British Racing Green with the cream panels - probably the most classic paint scheme you can find - and the frame and fork add to the classic appeal with the lugs and the traditional looking geometry. It was a bit of a change from my MCD, but looked really rugged when I put on the fatter tires I'd been craving. As built, my Peregrine is designed to be an everything bike, and so far, it's handled it all with aplomb. It's set up with big tires (700x52 Pirellis), fenders, a dynamo, and a comfy Brooks, and still manages to weigh in at around 25ish lbs. The ride is intuitive and comfortable and it transitions easily to the different surfaces in my rides. It is fast and smooth on pavement and rolls confidently on gravel. It has tons of clearance and mounts, too, so I can firmly mount some fenders to keep me dry and happy, but also do it in a manner that makes them quietly disappear. Oh, and it's a ton of fun to see the looks of people when you're on a traditional, fendered road bike, railing the local singletrack. =P It also has plenty of mounts and options for racks, and while I haven't set that up yet, I'm sure it'll be set up easily. The Peregrine just begs you to ride and keep going - explore one more trail, or ride the long way home. It doesn't seem to be too particular about what exactly you're riding, just that you are."

One mean and magnificent mutha.

"Sturdy, responsive, comfortable. Those are accurate descriptors of this frame's virtues. BUT, the most important part, to me, more than the flexibility of that eccentric bb, more than the fast and furious geometry, more even than the big fat tire clearance that gives me a cushy ride, is the sex appeal. Bikes Should Be Sexy, and this green machine satisfies my aesthetic cravings far above and well beyond any ordinary bro-bike vibes, for sure."
