Your BokehTi Shimano
THE LATEST EVOLUTION OF OUR UNIQUE MASON BOKEHTi, WITH CONFIGURABLE SHIMANO BUILD OPTIONS AND CUSTOMISABLE ELEMENTS
A world-leading, finely finished, titanium AdventureSport frameset. Welded and finished by a long-established, highly experienced maker in Tuscany Italy. Cutting-edge features like 3D-printed titanium Thru-axle/Flat-mount dropouts make this one of the most exclusive and advanced titanium frames available. The BokehTi is welded in small batches and is available on a pre-order basis only.
We have developed an entire new Ti tube set working with Dedacciai and Reynolds UK and the BokehTi uses the incredible Reynolds 3D printed Ti dropouts. Tuscany-made craftsmanship, super-high finish quality, our Mason Parallax2 carbon fork, with capacity for 650b x 55mm or 700c x 45mm, the BokehTi is your versatile friend for fast adventure and fun-filled bikepacking trips. Highly customisable build levels make the limited production Mason BokehTi a very special companion indeed.
For the BokehTi 2.0, we have chosen to keep all the character and capability, whilst enhancing its smooth, fast, ground covering nature. Updated with T47, internal routing through the BB and cleanly out through the chain stays, along with dedicated dynamo routing through the top tube, the routing is now very clean and practical.
MASON CUSTOM PROGRAMME
Individual Inspriring Bicycles are what we do. All our Mason models are as close to ‘custom’ as you can get with their bespoke tubing design and carefully designed build levels.
Whilst your frame is being welded and carefully finished you also have the chance to specify a full ‘Mason Custom Build’, basing your finished bicycle on a choice of components from our various carefully chosen suppliers. Please contact us for further information on this process and to start your dream build.
Each frame is welded to order: This is a highly refined and small volume product, so we make to pre-order only by taking a 50% deposit for the frameset. We can make certain detail alterations to the frame features and geometry and we can discuss these as part of the ordering process. Please contact us to get the process started. We refine your bike build whilst the frame is being built and finely finished, we then carefully assemble each bike at our Mason Cycles Workshop.

A DECADE OF DETAILS
With 10 years of perfecting & optimising every detail in our MASON range, along with over 25 years of metal frame design experience, we feel confident that all the features you'll ever need, along with some that you hadn't thought of, are lovingly and meticulously included in your frameset and finished bicycle.
We actively support some of the most experienced adventure and endurance riders, listen to our customers and work closely with experienced and passionate frame makers. Because of this rich mix, we are able to offer what we believe to be the most carefully designed, obsessively detailed and lovingly made framesets and bicycles in the world.
Hose & cable internal routing ports
Standard Routing with Dynamo: Suitable for any groupset, mechanical or electronic. Includes two reinforced ports for a rear dynamo cable through the top tube. Unused Multiports can be filled with blanks (e.g., Shimano Di2 or SRAM AXS groupsets).
Shimano Di2 Dedicated Routing: Accommodates a rear brake cable and additional ports for Di2 cables via chainstay and seat tube. Recommended for electronic routing, supporting Shimano Di2, SRAM AXS, or Campagnolo EPS. Optional dynamo routing via the top tube.
SRAM AXS Dedicated Routing: Suitable for SRAM AXS wireless groupsets only. Features ports for a brake hose, with no additional Multiports. Optional dynamo routing via the top tube.
Brake Setup
Specify your brake cable setup: This affects the MultiPort location for the rear brake hose. The Multiport can be located on either side of the down tube and depends on European/US or UK brake setup.
Eyelets
Rack eyelets: Rack eyelets are not a standard option and will need to be selected. Most Mason riders use systems like Tailfin, which don't require frame-mounted eyelets resulting in a cleaner overall finish.
Bottle and accessory eyelets: The Aspect has one set of bottle eyelets on the down tube and one set on the seat tube. There is an option to omit any of these eyelets.
Fender eyelets: Fender eyelets will be included as standard, but you can specify your frame without. These discreet eyelets are located at the seatstay bridge and inside the seatstays. If you have no plans to use a mudguard/fender these can be omitted. Mudguard/fender mounts on our forks are always included as standard.
Head Tube length
You can choose a shorter head tube to give your bike a racier position, on all sizes except on the 48cm frame. The length of the shorter tube will be the same as that for the next size down. For example, a 56cm frame has a standard heat tube of 185mm, which can be shortened to use the 170mm tube from the 54cm frame. Consider this change very carefully, consulting with a professional bike fitter if you need to ensure the correct fit.
MASON MAKERS
BUILT WITH CARE AND ABSOLUTE ATTENTION TO DETAIL
We’re proud to collaborate with independent, bespoke frame makers who are at the pinnacle of their craft. This is something we care about a lot and we feel honoured to be working with small makers in Italy for most of our models, some who have been dedicated to the art of metal frame production for nearly 75 years.

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.
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, skill level and intended model usage are very different. This means that there will invariably be different frame size requirements, even for people of the same height and inseam.
SIZING ADVICE BASED ON MASON MODELS
ROAD, ALL-ROAD & GRAVEL - Aspect | Resolution | Definition | SLR | BokehTi | Bokeh | Exposure: Size range is 48cm to 62cm depending on specific model. The chart dimensions show the extremes of useable frame size based on height and the rider size range is very similar for all our frames with 6 or 8 standard sizes.
ULTIMATE ADVENTURE - InSearchOf: Size range is 42cm to 58cm [5 sizes]. As a start point, we would recommend selecting one size down from your normal 'road' frame size. For example, if you would normally ride a 54cm then a 50cm InSearchOf is probably best for you.
ADVENTURE HARDTAIL - RAW | Macro: Size range is Sml to XL [4 sizes]. With the advent of modern, more progressive mountain bike geometry, the sizing process is even more fluid. The Mason RAW and Macro are no different: seat tube lengths are kept deliberately low so riders have a certain amount of flexibility in choosing size based on their preferred reach, wheelbase, handling characteristics and intended use. For instance, for high speed and loaded up stability you may prefer a larger frame that will also provide more pack space in the front triangle. Or, if you are spending most of your time on twisty woodland singletrack, you’d benefit from the shorter wheelbase and extra response of the smaller frame.
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 we would always recommend having a proper bike fit done before committing, especially if you feel like you may be between sizes. If you do fall between our frame 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.
CONFIGURATION: With all models, you can use our drop down menus to configure your finishing kit to suit your needs, including which brake lever operates front/rear wheel and for MTB we’re happy to cut down the handlebar to your desired width.
Please email us here or call 01273 463000 if you have further requirements that you would like to discuss, we are always happy to help.
