Outrageously beautiful, in my opinion anyway, this Saffron Frameworks custom build road bike offers a supreme ride and performance.

There's an exciting resurgence underway in the UK. Away from the glare of the mainstream, where the likes of Cav and Froome are regular fixtures in the sports pages of the national newspapers, there's a thriving bespoke framebuilding industry. There's even a dedicated show that attempts to display the most interesting creations, Bespoked UK, held in Bristol every April.

Saffron Frameworks was founded in 2009 by Matthew Sowter. He is just one of a growing number of framebuilders who specialise in made-to-measure frames, crafted to the exact requirements of each customer and finished with a custom paint job. It's a very different experience to walking into a bike shop and buying an off-the-shelf bike from a large manufacturer. And, like most of these (typically young) framebuilders, he solely works with steel.

The level of quality, for someone who has only been building frames for a handful of years, is exquisite. He has won various awards over the years, testament to the quality of his workmanship. As a result of his growing reputation and the popularity for going custom, there's a long waiting list to get a Saffron frame.

If you want to see the man in action, this nice video adds a bit more background. Wondering where the Saffron name comes from? 

A personal build

The Saffron tested here is Matthew's very own personal bike, built up as a dedicated winter bike. Every frame he builds is the result of a collaboration with the customer, but this bike has been assembled to his very own wishlist of requirements. It features colour-matched mudguards, integrated lights, disc brakes, space for 28mm tyres and some smart equipment.

Suffice to say, the bike hasn't been customised for me in any way, but as luck would have it, Matthew and I must be about the same height because the bike – a 56cm frame size – fitted me like a pair of well-worn slippers. All I had to do was set the saddle to the correct height and off I went.

In a world of carbon copies, the Saffron really stands out. Many of the test bikes that pass through the road.cc office turn heads but few receive as many admiring glances and comments as the Saffron. One reason for buying a bespoke bike is the opportunity to get a custom paint job, and the finish on this bike is first class. The custom painted mudguards are the icing on the cake, and lift the aesthetic appearance of the bike into another class. It's probably the nicest looking mudguard-equipped bike I've ever clapped eyes on.

Saffron only works with steel – this one is made from Columbus Zona tubing – but the colour-matched Kinesis Tracer fork is carbon fibre. While the fork has a conventional quick release axle, the rear dropouts accommodate a 142x12mm thru-axle, an emerging standard on disc brake-equipped road bikes.

The bike has been built up as a durable and versatile bike for the winter, but also with an eye on summer riding. It's a year-round bike, effectively, intended to be practical and comfortable, whether it's for winter commuting or summer audaxing.

As a Saffron customer you would choose your own components, but here a Shimano Ultegra Di2 groupset provides the reliability and shifting performance we've grown accustomed to with the Japanese company's electronic drivetrains. There are also Shimano hydraulic disc brakes with 140mm disc rotors at both wheels and the latest flat mount fixings.

The build features Kinesis RaceLight Disc tubeless-ready wheels with Schwalbe Pro One tubeless tyres, in a fashionable 28mm width. The frame will take 30mm tyres with the mudguards removed.

A smart demonstration of the attention to detail offered by Saffron is the neat integration of the Supernova Airstream 2 light and matching Tail Light 2. The front light is fixed to a small bracket mounted to the fork, and houses the battery that powers both lights. The front light projects 205 lumens with a run time between 2.5 and 7 hours, with three brightness modes available.

All the wiring for the Di2 drivetrain and the Supernova lights has very neatly been routed inside the frame.

The complete bike weight is a respectable 9.71kg (21.40lb).

Ride and performance

I've ridden a fair few steel bikes over the years, and the Saffron provided the predictable ride character that I love about a really well-made steel road bike. With the large volume tyres run at a low pressure, the comfort was supreme, the bike taking care of horrible road surfaces and providing much smoothness.

It's a lovely bike to ride at a leisurely pace, taking in the scenery on a longer ride and deciding which pub to stop at for lunch. But there's more to the Saffron than a gentle touring or audax bike. Push a little harder and you can detect a stiffness in the frame that allows you to make rapid progress. The steering is light and it turns into corners with tight control and precision. Short lunchtime rides are fun and exciting on the Saffron.

There's a lovely marriage of frame and equipment that makes it a really practical bike for everyday riding. Each component has been carefully chosen and it all shines individually but comes together really well. There's really nothing I would change about the bike if I were to own it (apart from the fork, see below). The brakes are firm and powerful and the Di2 is quiet and crisp, while the integration of the front and rear lights is beautifully done, the front providing a good beam and brightness for night time country lane cycling.

It's a really good all-rounder. It was right at home in the steeper Cotswolds hills, though the weight does rob you of some pace when the gradient increases. On the descents, it tracks sharply with a precision from the frame that allows you to move the bike around the road, such as lining up for a hairpin corner, with great confidence. It filters out much of the harsher bumps and retains composure even at higher speeds.

My only real grumble about the bike is the rotor rub from the front disc brake, most detectable when climbing out of the saddle. I'm not a heavy rider by any means, but a switch to a fork with a thru-axle might reduce this symptom.

The bike is a fine expression of Matthew's skills and attention to detail, and the finish is stunning. Let Matthew build you a bike and you certainly won't be disappointed. I really liked riding the Saffron and could quite happily have kept riding it into the spring. Now, where's my wallet...

Frameset

Tell us what the frameset is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about the bike?

Saffron says:

Cyclists living in the UK tend to get most of their miles in wet weather and low light on road surfaces that are not always perfect. For this reason I wanted to construct myself a 'winter' bike which would also showcase some new technologies that have recently found their way into road cycling from other disciplines. This bike will also see regular mileage on my new commute, as I'm moving further away from the workshop.

Shimano's new flat-mount road specific disc brake calipers were the first must have for the project, the body is so small it will allow for far more creative use of disc brakes in the slightly constrained spaces on road bikes. The power and modulation disc brakes offer in all riding conditions is hard to argue with. UK company Kinesis provided a tubeless compatible disc wheelset which was used in conjunction with Schwalbe's supple Pro One tyres which should give miles of grippy puncture free riding, with the 28c width soaking up the worst of what the UK roads have to offer. More comfort was added by using a full carbon 27.2mm post, allow for some flexibility – this was topped with Brooks' new c13 carbon railed Cambium saddle.

For a bike that's going to be ridden in the worst conditions Di2 really comes into it's own; no cables to gunk up means shifting is crisp and clean all the time. Lighting on a bike like this should not be an afterthought or an eyesore, and whilst we didn't want to go for a dynamo system Supernova still offered us the best option. The front light is powerful with a road specific lens to avoid dazzling drivers, and the rear light is so small and powerful we managed to neatly mount it on the offside dropout for maximum visibility on UK roads. Our intention with this off-centre placement was to fool an approaching driver that the centreline of the bike is in fact further toward the middle of the road than it is, hopefully encouraging them to allow more room when passing. All cables or hoses for the the lighting, gear shifting and brakes run internally on the frame. The mudguards are designed to be left in place in normal use on this bike and as such were painted to match the frame and fork – strong colours in a bold, classic pattern. Specifying a 142x12mm thru axle serves to stiffen the rear end of the bike, removing the flex that would normally occur by the slight lengthening of the chainstays and keeping the handling and acceleration snappy.

Now comes the interesting part, with the geometry and specification of this bike it really is a jack-of-all trades. We can remove the mudguards (leaving the mounts hidden on the inside of the stays and forks) and lights, if needed. Up the tyre size to it's maximum 30c with a little tread, and take it off-road on to explore more of the countryside. Alternatively pop on a pair of fast rolling 25s and the front end geometry and stiff stays will mean you're on a great handling race bike.

Outrageously bland and over-priced in my opinion, there's so much more bike to be had for that money.

I picked up my Saffron bike a year ago. After riding 5,000 miles it still thrills me. I love it and can't thank Matthew enough for such a joyous ride.

Ciarán probably prefers something with flashier colours and go-faster stripes. Plenty of choice out there for him at, err, more affordable price points.

I also got a bike made by Saffron last year and can't over emphasise the attention to detail and craftmanship that Matthew applies during the entire process. I still get a buzz every time I clip in and ride off.

The thing about a bespoke bike is just about everything can be specified to personal preference so that pretty much guarantees that everyone else will find something they don't like or would have chosen differently!

´And, like most of these (typically young) framebuilders, he solely works with steel.´

Apart from the (carbon) fork which he buys in from Kinesis, apparently.

 

Also something that grates - those lights, whilst the cable routing is certainly clever and internal, are a long way from being ´integrated´. Something like the Vanmoof has real integrated lights, and should be applauded for its innovation. I´ll never get why a ´winter´ bike doesn´t come with a dynamo hub as standard!

Passion and artistry will always command a premium price from those who appreciate such things and can afford it. As actual owners of these bikes have stated, it's not just about being a good bike but also the joy of simply owning something beautiful and not about fretting that you could have bought something with a similar on paper spec for less. A steel bike will last a very long time and as this is a custom build, then if you want dynamos or different colours or rocket fins or whatever then you can probably have them.

Exactly if I were to buy a steel frame, it would have chrome luggs, classic steel

So, technically, he's not working with carbon then, is he.

Come on, don't be deliberately obtuse.

It's perfectly possible to make a fork out of steel, he's chosen not to do so, hence he doesn't work 'solely with steel'.

 If you wanted steel forks he'd happily build you some.

If you want carbon then he will have to buy from an external source.

He clearly does work solely with steel in the manufacture of his products. The quote was obviously referring to the frames that he builds.

Lovely frame

As to the comments - honestly its getting more and more like a youtube comments section on here.
