Mason has launched the Definition 3.0, its long-distance all-road bike that we first saw a few weeks ago when Transcontinental Race winner Josh Ibbett rode it in the 2,700km Japanese Odyssey endurance biking occasion. On the time, we had the images however Mason was protecting shtum concerning the replace. That has all modified with the official unveiling.
We’ve been enormous followers of the Mason Definition since its launch in 2015. Again then, we described it as “a four-season long-distance machine with the manners of a tourer and the temperament of a race bike”, and that just about sums it up.
The Definition shares a geometry with the Mason’s Decision, produced from Columbus metal, but it surely’s designed to supply a sportier really feel whereas retaining long-distance consolation.

It’s constructed from Dedacciai aluminium alloy tubes with Mason’s customary consideration to element. In case you ever chat with model founder Dom Mason, you’ll quickly recognise that he’s positively the form of bloke who sweats the small stuff. He’s meticulous-going-on-obsessive concerning the trivialities of motorbike design.
What has at all times set the Definition aside, although, is the journey high quality. The Definition rides fantastically with chic dealing with.
After we final reviewed a Mason Definition in 2022, reviewer Stu Kerton mentioned, “The way in which this factor rides is a masterclass in bike design and engineering.”
Mason has up to date the Definition for 2024.
“This time round, the Definition has obtained some modifications and new options to optimise and refine for the long-distance and all-season using that it already excels at,” says Mason. “With our ‘Experience Pushed Design’ mantra as a agency guideline, we now have realized a terrific deal from our riders and clients since its launch in 2015 and there have been many operating modifications, updates and new variations as our journey has progressed.”
So what has modified? Effectively, first, we’ll inform you what hasn’t. The geometry stays the identical as ever, and that’s factor as a result of it permits you to journey all day in consolation. If you wish to put some figures on it, the 56cm frameset comes with a 560mm seat tube (centre of backside bracket to prime of seat tube), a 561.1mm efficient prime tube, and a 170mm head tube.
In our 2022 evaluation we mentioned, “The geometry is spot on, with a steadiness of angles and tube lengths that sits in the direction of the endurance finish of the market. The entrance finish is not as razor-sharp because the raciest of race bikes, but it surely’s very shut, and the marginally slacker head angle – plus a wheelbase a couple of millimetres longer to just accept full mudguards – means dealing with that is a little bit bit much less frantic. It actually permits you to journey the Mason shortly over lengthy distances.”
That’s the entire thought of this bike. The Definition is available in eight completely different sizes from 48cm as much as 62cm, catering to the overwhelming majority of riders on the market.
Mason hasn’t messed with the clearances on the Definition 3.0 both. You’ll be able to nonetheless match 32mm tyres with mudguards and 35mm with out, so there’s loads of practicality right here.
What has modified is the brake hose and kit cable routing. Mason says that the recognition of digital shifting and the elevated use of 1x [single chainring] programs has allowed it clear issues up. All cables and hoses now run via the down tube and out via the chain stays through a particular backside bracket shell.
Mason makes use of the area freed up by the brand new cable routing so as to add devoted dynamo cable routing ports to the highest tube for many who need dynamo lighting and charging.
“This vital revision implies that the cable is extra simply routed between entrance and taillights and provides various mounting factors, both on the seat clamp or dropout, relying on rack and bag setup and necessities,” Mason says.
Bigger body sizes now include outsized seat tubes “to maintain journey response and sturdiness constant all through the scale vary and maximise energy switch for bigger, extra highly effective riders”.
Smaller body sizes get a 27.2mm carbon seatpost that’s designed so as to add consolation for riders on the decrease finish of the peak/weight vary. Then again, taller and customarily heavier riders now get a 31.6mm diameter seatpost.
One thing that you simply may not discover is that Mason has additionally labored on bettering longevity.
“Improved sturdiness is achieved via uprated tubing therapy and accent eyelets, making certain resistance to harsh circumstances,” says Mason.
There are new colors too, Mason having transferred SensorBlue (essential pic) over from elsewhere in its vary and launched a brand new metallic ShutterBlack end (above). The present Vela choice (under) stays.
The Definition is offered in Shimano, SRAM, and Campagnolo builds.
Has the previous Definition magic been retained? Fortunately, we gained’t have to attend too lengthy to search out out as a result of our tech author Suvi Loponen has been using the brand new mannequin for the previous couple of weeks. Keep tuned for a evaluation on street.cc quickly.
