MACRO FRAMESET - ADVENTURE HARDTAIL / SHIMANO / UP TO 60MM

MACRO FRAMESET - ADVENTURE HARDTAIL / SHIMANO / 29X2.4”(60mm)

"The Macro is amazing. I already knew it was an excellent climber and fast descender from the Atlas Mountain Race. It was more than up to the task, helping me keep up the pace I needed to finish the Accursed Race in third place."  Josh Ibbett 

RIDE DRIVEN DESIGN

The Macro has been tested in the world’s toughest environments. The Silk Road Mountain Race, Accursed Race, Atlas Mountain Race and the Arizona Trail have already established the Macro as vital equipment for MASON riders Josh Ibbett and Angus Young, as they take on the extreme environments of ultra endurance races.

NEW LIGHTWEIGHT CONFIGURABLE ADVENTURE HARDTAIL

The MASON Macro combines the capability to carry bikepacking gear across variable off-road terrain with the imperative to keep moving at racing speed. Build a lightweight, flat bar, fully rigid bikepacking machine or combine the Macro with a suspension fork to enhance comfort, control and momentum on extended, fast, multi-terrain adventures with more challenging trail conditions. The Macro is highly configurable, conceived around bikepacking loads, accessory attachment and fluid-carrying capacity from the outset. It is designed for customisation, allowing the rider to fine tune a configuration that matches their requirements and planned adventures.

TECHNOLOGY

• CUSTOM MASON X DEDACCIAI TUBING / 7000 SERIES/ENDURANCE OPTIMISED - The entire Macro tubeset was developed in conjunction with Italian tube gurus Dedacciai, using their lightweight 7000 series, 29er, Aluminium tubing. The tubes are drawn from billet in their Italian factory and then shaped and formed to MASON spec. ENDURANCE OPTIMISED: We work closely with the engineers at Dedacciai to optimise all tube shapes and dimensions, for comfort, durability and pedalling performance. Along with strength for mounting points and proper clearance for modern wheels, tyres and transmissions.
• UDH EQUIPPED - This frame is equipped with the 'UDH' [Universal Derailleur Hanger]. The 'Universal Hanger' standardises the shape and fixed position of the hanger across the industry and is compatible with all modern rear mech types from all major brands. Our UDH dropouts are compatible with all SRAM 'T-Type/Transmission' rear mech models, and any future rear mechs and gearing systems that are designed to work with the UDH standard.
• DROPPER READY - A dropper-post is great for getting the saddle out of the way for steeper, rougher and more technical riding, especially with a loaded up bike. The 31.6 post size allows the use of most modern dropper-posts. The dropper control cable can be routed through the Macro frame, using 'Integrated' routing via the head tube, or 'Internal' routing through one of the down tube 'MultiPorts'. Important: Scroll to see 'essential dimensions' with maximum dropper length details.
• HOTSHOE2 CARBON FORK - As with all our framesets, we design and tool for our own fork. Both the MASON ISO and Macro use our MASON HotShoe2 carbon fork. The refined shape maintains ride quality and feel and there are multiple mounting points for accessories, including our TriMount on the fork crown for ‘MASON Shutter’ load-bearing fender and 'MASON Condenser' rack. Internal routing for hose and dynamo wire and light mount on crown. Huge clearance for up to 29 x 2.6" tyres.Fully tested to MTB standard with 483mm crown height [equal to a typical 100mm travel XC fork inc. sag] and 50mm offset.
• 100MM SUSPENSION FORK - The Macro is designed around a 100mm suspension fork with a static axle to crown height of 503mm and an offset of 45mm. This is the ideal amount of fork travel to help keep momentum on fast, rough, multi-terrain adventures, where washboard or steeper descents with drop-offs may be encountered.
• 8 FLUID/ACCESSORY MOUNTS - The Macro is designed for long-distance bikepacking and adventure riding, so the frame and HotShoe2 fork are fitted with plenty of fluid and accessory mounts. There are 2 x bottle/accessory mounts on the HotShoe2 fork, as well as our TriMount for MASON 'Condenser' rack and 'Shutter' load-bearing fender. There are also threaded rack mount eyelets on the seat stays and dropouts.Standard frame mount bosses: x3 down tube (top side); x2 down tube (underneath); x2 seat tube; x2 top tube for securing a top tube pack. Multiple eyelets allow accessory adjustment for efficient use of front-triangle space. All eyelet positions are optimised, meaning fluid carrying and bag space are maximised within the frame. The 4th accessory/tool-keg/fluid mount, is mounted as low as possible under the down tube, giving space for a larger bottle or bag, whilst still maintaining clearance for larger wheels/tyres.
• 56MM INTEGRATED HEADTUBE - The Macro uses a specially developed Ø56mm, straight head tube. The large diameter and thick wall dimensions maximise strength and weld area at this crucial junction of the frame. Oversize Ø52mm bearings at the top and base have a large contact area and give increased durability.
• CONFIGURABLE ROUTING - The Macro is designed to be highly adaptable and configurable, this includes 'configurable cable routing options'. Choose to route your hoses/cables through the head tube & frame, giving unobstructed mounting space for essential frame bags, or route through the down tube MultiPorts. Choose a combination of both routing styles to work seamlessly with your chosen bike, bag and accessory setup - Route the hoses 'integrated' and your dropper-post cable 'internal', or just the brake hose integrated when running electronic shifting, for a super clean and unobstructed setup.
• BOOST SPACING - 148 x 12 at the rear and 110 x 15 at the front for max compatibility with modern MTB wheels. Boost spacing allows us to optimise frame clearance and stability and run large rim widths and big volume tyres.
• THREADED BB - The Macro frames use high quality MASON design, 73mm, BSA, threaded bottom brackets. The BB shell is machined from billet in Italy and 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 an ideal interface with a metal BB shell.
• THRU BB - Thru-BB' is unique to MASON aluminium frames. The large 56mmØ presents a large weld area to the base of the down tube and then steps down to the 68mm [road/gravel] & 73mm [MTB] width threaded seats. This step-down provides plenty of space around the outside of the bottom-bracket bearings to allow the control cables and hose to pass through on the way to the chain stays/seat tube and out to the brake, rear mech, dropper-post etc. IMPORTANT: This BB shell design requires the use of a bottom bracket with a 24mm or 30mm 'sleeved' axle like most Shimano or SRAM DUB, because the hose/cables/control wires run through the shell and under the axle. DO NOT use a bottom bracket type without a sleeve. Campagnolo sleeves are available on the site HERE. Please contact us if you would like advice on compatible cranksets/BB types.
• SWTICH LEVER - This model uses SwitchLever Thru-Axles front and rear. This high quality axle system features a removable lever to be used with both axles. Store the lever in the front axle for quick use or remove completely for extra security and a clean, low-profile look.
• 160/180 FLATMOUNT - Our HotShoe2 [Macro & InSearchOf] and RangeFinder [SLR, Exposure, Bokeh3] forks, were amongst the first carbon forks to have Flat-Mount compatability for 160 and 180mm rotors. This allows for controllable, dependable stopping power when riding loaded and in steep, rough conditions.
• 1X DRIVETRAIN SPECIFIC - Designed specifically around the latest 12 speed mountain bike drivetrains allowing for greater tyre clearance, chain security and performance in muddy conditions. Ultra wide gearing options provide ample range for any terrain.
• 29ER - Large diameter wheels and tyres are extremely fast-rolling, with a big contact-patch and low rolling resistance. Bikes with 29" wheels are ideal for long-distance adventure, giving speed, comfort and forgiving handling, over an extremely wide range of terrain. The MASON Macro is designed for 29” MTB wheels and tyres up to 2.4”. Recommended tyre sizes: 29 x 2.0” - 29 x 2.4”.
• CATAFORESI ANTI-CORROSION TREATED - This frame is Cataforesi anti-corrosion treated, inside and outside of frame tubes, before acrylic primer, topcoat and 2 tough clearcoats.
• ISO TESING - All our framesets 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, with the Parallax and RangeFinder & HotShoe2 forks going through the MTB test with its even tougher 'Drop Testing' standards. We also 'overtest' by applying extra loading to fork cargo eyelets for example. Our Adventure Hardtail frames frames are ISO tested to very tough MTB standards. Because of this we are confident that these frames will last you a lifetime of hard riding. Where one of our designs does not properly fit an ISO category, we work with the testing facility to devise our own testing schedule. 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.
• SHUTTER MUDGUARD - ISO tested to 2kg and specific to the HotShoe TriMount. Standard equipment with ISO framesets and bikes. The Shutter helps keep dirt and water away from the rider, meaning you stay fresher on longer rides + it keeps your packs cleaner/dryer. The load platform is for bulky/lighter loads or frequently accessed items, It's ideal for something like a sleeping mat, bivvy bag or jacket etc in drybag. it avoids having to always use a bar-bag which can be annoying and restrict hand positions and mounting points. The flare at the front is for max coverage with large tyres to help stop stuff blowing back, the 'kickup' at the rear is to stop water/grit being hurled into the headset to prolong the bearing life.

GEOMETRY AND SIZING

• GEOMETRY: https://masoncycles.cc/products/macro-frameset
• SIZING: This page gives you some guidelines based on rider height, but these are only a starting point for a proper bike fitting. There are of course many other factors to consider when choosing the right size for you and sizing advice will vary depending on your choice of model from the Mason range and the way that you intend to ride it. We're always here to help of course and would always recommend a professional bike fitting and visiting us for a ride on the Mason Cycles riverside gravel/country lanes test-loop if you can. There is further advice, based on specific models, below the height chart.
