Resolution Frameset

We developed the original Resolution frameset in 2014 and have updated it ever since. The latest, Flat-Mount/Thru-Axle version that you see here is the culmination of almost 2 years work with the maker in Italy and BEAR in the UK. The result is a thoroughly modern, Multi-Surface, Continent Crushing, Ultra-Endurance, Se4son, adventure machine. Capable of keeping you fresh and engaged whilst crossing a country or delivering you swiftly home at the front of the club run.

MultiPort internal cable routing, the latest standards in braking and wheel-retention, disc brake specific, suitable for large volume tyres mudguards and rack. Choose the steel Resolution for ultimate comfort over distance and that certain ride quality. Why steel? Read more here.

Our Resolution2 frame set is a real first. A combination of forward thinking technology, the best materials and hand-crafted excellence in construction that truly set it apart from any other brand.

We have worked with BEAR to produce a very special set of dropouts that are exclusive to Mason and that have not only managed to keep the legendary refinement, lateral rigidity and ride-quality but have added to it and introduced our Thru-Axle system and neat new features too!

Our own MultiPort adaptable, internal cable routing system is unique for a frame of this type. Developed by us to allow your Mason frame to be used with a combination of control systems and adapt and evolve with your requirements and riding styles. We were the first to bring this type of system to a performance steel frame. We've also re-positioned the brake hose mounts to align exactly with new Flat-Mount standards and added a neat, reinforced Di2 wire exit on the drive-side chainstay.

Read more about MultiPort here.

Every tube on this frame has been hand picked to give a performance advantage. The ovalised and facetted Spirit top tube, the oversize 'D section' Spirit down tube, our custom bend, hourglass profile seat stays, the oversize seat tube, and the modern taper head tube with stainless bearing seats takes our own, taper-steerer 'Aperture2' full carbon Thru-axle / Flat-mount fork.

Combining these tubes with modern componentry and Mason 'Progressive' geometry is the formula for something very special.

Read more about the tubing here.

All eyelets on frame and fork are hidden out of the way where possible, so this adaptable frameset hides it's multi-purpose capabilities until you are ready to bolt on the wet weather or luggage carrying gear. While working on the new drop-outs, we have also removed the rack-mounts from the rear of the dropouts and integrated them neatly into the CNC machined design of the dropout. Minimal, discrete, functional and extremely tough.

For the bottom bracket, we choose a 68mm, BSA, threaded standard for our 4Season frames because we believe it gives greater durability and creak-free reliability over many miles. The threaded BB is easier to service using standard tools and you are more likely to find a replacement when adventuring far from home.

All this, backed up by award-winning heritage and exemplary Mason Cycles customer service.

We also offer a ready built bike range here.

This page gives you some guidelines based on height, but these are only a starting point for a proper bike fitting. The dimensions show the extremes of useable frame size based on height.

Sizing chart

Fitting a bike to a rider is an important process, this information is a start to the process but it’s not really possible to give 100% accurate fitting instructions online.

Humans are odd shapes, each person’s physical dimensions: arm, torso, femur length, level of flexibility even skill level are very different. This means that there will invariably be different frame size requirements, even for people of the same height and inseam.

We are experienced in sizing and geometry, so of course we will be on the end of the phone or email to help and advise, but I would always recommend having a proper bike fit done before committing, especially if you feel like you may be between sizes.

We have specified bar width, stem length, and crank length to be the best fit for the majority of riders on each frame size, but we can sometimes make adjustments to this at your request. Please contact us for advice, or just let us know your sizing requirements in the comments box at the checkout page.

We'll set-up the front brake to be operated by the Right Hand lever for all UK destinations. For destinations outside of the UK, we'll set-up your bicycle with Front Brake/Left Hand as standard. It's no problem for us to set-up the brakes in your own chosen configuration, please state in 'Order Notes' how you like 'em.

If you are between sizes, it’s probably best to go with the smaller size. It’s easier to make a smaller frame fit a little larger than vice versa.

EN Tested

All our frames and forks complete the brutal strength and fatigue testing to comply fully with EN regulations. They are pushed, pulled, dropped and twisted over 100,000 times and must survive without any damage before they can pass.

It's not law that frames and forks have to be tested to their limits like this, but our frames will always be tested in this way, so you can be sure that your MASON frame not only looks beautiful with a ride quality to match, but it is tough, safe and dependable too.

Multiport

Unique to MASON. Our frames use an adaptable, internal cable routing system. Developed by us to allow your Mason frame to be used with a combination of control systems and adapt and evolve with your requirements and riding styles. We are the first to bring this type of system to a performance steel frame. Interchangeable alloy parts allow five options:

1. Full cable outer. 2. Hydraulic Hose. 3. Split outer. 4. Electronic cable [e.g. Shimano Di2]. 5. Blank.

Taper Head Tubes

Our frames use modern 1-1/8” - 1.5” taper head tubes. Pioneered by composite frames, the taper head tube makes huge sense for metal frames too;

The large overall diameter provides a useful weld area. The fully integrated headset is light and has a very low stack-height. Large 1.5” lower bearing, mated to a tapered carbon fork steerer, spreads the load and gives flex-free braking and instant response to steering input.

Threaded Bottom Brackets

We choose a more traditional 68mm, BSA, threaded standard for our AdventureSport frames because we believe it gives greater durability and creak-free reliability over many miles. The threaded BB is easier to service using standard tools and you are more likely to find a replacement when adventuring far from home. A properly lubricated, threaded BB is also an ideal interface with a metal BB shell.

Hourglass Stays

We tried many shapes before settling on this one, the wall thickness tapers from top to base and the perfect ‘hourglass’ profile gives a sublime, smooth ride with the added spring of steel keeping things lively. We add a custom bend at the base to work with the disc-rotor and calliper.

Fork

Unique to MASON. This frame is fitted with our new 'Aperture2' 365g, Ø12mm thru-axle/flat-mount, monocoque carbon fork. Features: Mason F-Stop axle system including replaceable axle inserts and clockable axle, TrueTaper steerer, Internal Routing, Full mudguard clearance, space for 30mm tyres + 'guards, Custom layup UD carbon construction, discrete eyelets.

F-Stop Axle System

The Mason F-Stop Axle System was developed for our exclusive Aperture2 fork, used on our Definition, Resolution and Aspect bicycles.

The axle uses a positive-closure release lever, ensuring that the wheel is always securely and firmly mounted with the added advantage of a visual check for the lever closure and orientation. The F-Stop system also includes a ‘clockable’ thread on the axle, meaning you can always position the release lever exactly where you want it.

The Aperture2 fork also features removable tip inserts meaning that all wearing parts are replaceable, vastly extending the life of your Mason bicycle.

Columbus Tubing

This frame is constructed from a unique blend of Columbus Spirit and Life tubing. Hand Selected, custom shaped, seamless, progressive butted, fine grain, niobium doped and joined with perfect Tig welds.

27.2 Seat Post

Our oversize seat tubes don't house oversize seat posts. The large diameter seat tube helps the 'core-stability' of the frame but large, stiff seat posts don't help rider comfort. A 27.2mm post helps to dial out road-buzz and the smoother ride means you stay fresher for longer.

Disc Brakes

This frame is designed for disc brakes. They work consistently in all conditions, pull up quicker in the wet, they don't grind your expensive rims into black sludge and in my experience they change the whole riding experience for the better, especially when coupled with modern disc-specific wheels and high-volume tyres. You’ll find yourself riding in a more confident, controlled, fluid and ultimately more efficient way.

InBoard Disc-Mount

The calliper is mounted on the chain stay, this allows us to use lighter more comfortable seat-stays and gives a flex free mounting for the post-mount components to be welded to. Mounting the brake on the chain stay also keeps it cleanly out of the way of rack and ‘guard stays.

Internal Routing

The cables, hoses and electronic shift control wires run through the frame tubes, guided by our Mason 'MultiPort' adaptable inserts. Interchangeable Internal routing keeps the control cabling away from road dirt and grime, helps avoid accidental damage, makes cleaning easy, de-clutters your bike and means you can adapt your bike easily to work with various shifting and braking methods. For adventure and endurance riding, internal routing also has the advatage that it is easy to strap frame packs to the frame tubes without being hindered by external cabling and hoses.

Integrated Headset

Integrated, 41.8ø upper, 51.8ø lower, for taper head tube. Both bearings are ‘ACB’, meaning ‘Angular Contact Bearings’. The head-tube seat angle is 45º.

The headset drops into a tapered seat in the head tube and is tensioned using a headset tensioner within the fork steerer. Tensioning the headset centres it on the taper and prevents any play. The larger lower bearing allows a tapered steerer and larger crown. This gives sharper response, helps reduce flex under braking and spreads bearing load.

ISO Testing

All our frames complete the intensive strength and fatigue testing to fully comply with ISO standards. The AdventureSport range of frames are put through the tough road race ISO testing, with its brutal Horizontal Fatigue test. The Parallax fork goes through the MTB test with it's even tougher 'Drop Testing' standards. Because of this we are confident that these frames will last you a lifetime of hard riding.

It's not law that frames and forks have to be tested to their limits like this, but our frames will always be tested in this way, so you can be sure that your MASON frame not only looks beautiful with a ride quality to match, but it is tough, safe and dependable too.

FlatMount Brake Calipers

Flat mount disc-brake callipers are lighter, neater, and open up more space within the dropout area for racks and ‘guards. The calliper is mounted to the dropout, allowing us to use a lighter, more comfortable seat-stay.  Up front, the calliper is mounted directly to the fork [via the brake manufacturers adaptor] and offers a cleaner and more minimalist appearance and also provides a compact packaging of the brake caliper.

 

DForm Downtube

Our Resolution frame uses a special 'D-Section', Columbus Spirit, down tube. We also worked with Dedacciai to design and tool for the exclusive Mason ‘DForm’ Ti down tube for the BokehTi. It is not a simple ‘D’ section and varies in shape from being taller/narrower at the head tube to being wider and lower in section where it meets the BB shell. This shape allows a very wide weld where the tube meets the BB, giving it great stability and ensuring that the weld doesn’t excessively overlap onto the base of the seat tube.

Custom Tubeset

We choose each tube individually, considering the influence that it will have on ride quality and overall performance. We will use a blend of tubing types, custom shapes and bends to help us achieve this goal.

Modern metal frames draw on many of the design influences learnt from composite frames, such as oversized BB’s, taper head tubes and switchable internal routing. Teamed with a properly designed carbon-monocoque fork like the Parallax or Aperture2, the contemporary Aluminium, steel or Titanium frame is a formidable piece of kit.

Thru-Axle Front & Rear

Our Steel and Alu. frames use the Mason ‘F-Stop’ thru-axles up front and bolt-thru axles at the rear. Our Titanium frames use the F-Stop axles front & Rear.
The F-Stop system is clockable to your desired position and can be adjusted as it 'beds-in', giving you a 'tool-free' and serviceable thru-axle with a familiar QR-style lever locking system. Threads are replaceable if damaged.

Essential Dimensions: Resolution/Definition

BRAKING

Resolution Rotor Size: The fork can take a Ø140 or Ø160mm rotor [using adaptor], if you are using Shimano IceTech rotors then Ø140mm rotors either end are fine in normal use, although Shimano recommend Ø160 both ends for larger riders or extended long descents, especially when loaded. SRAM recommend Ø160mm front/rear. A Ø160mm up front is best if you are using cable braking. The Resolution2, with Thru-Axle front & rear will now accept a Ø160mm rotor on the rear. [140mm is the maximum recommended diameter for the V1 rear].

Resolution Caliper Type: Frames are fitted with the Flat-Mount front & rear (adaptable to post-mount with correct adapter). There are no clearance issues with modern Shimano or SRAM hydraulic systems or mechanical systems such as ‘TRP Spyre’. Some bulky systems like the ‘TRP HyRd’ may have compatibility issues on smaller size frames. Please contact us for advice if you are in doubt.

Definition Rotor Size: The fork can take a Ø140 or Ø160mm rotor [using adaptor], if you are using Shimano IceTech rotors then Ø140mm rotors either end are fine in normal use, although Shimano recommend Ø160 both ends for larger riders or extended long descents, especially when loaded. SRAM recommend Ø160mm front/rear. A Ø160mm up front is best if you are using cable braking. 160mm is the maximum recommended diameter for the rear.

Definition Caliper Type: Frames are fitted with the flat-mount front and flat-mount rear. There are no clearance issues with modern Shimano systems or mechanical systems such as ‘TRP Spyre’. Some bulky systems like the ‘TRP HyRd’ may have compatibility issues on smaller size frames.

NOTE: Our frames are compatible with most modern disc-brake systems but may not be suitable for ALL brake callipers. Please check clearance before purchasing your braking system.
