Bokeh Ti GRX Di2 £6,300.00

Bokeh Ti GRX Di2

"Mason’s new Bokeh takes all that I loved about the original alloy bike and has amped it up to the all-roading, gravel-riding titanium max."

Overall: 4.5/5. BikeRadar, 2020.

The exclusive Bokeh Ti frameset is welded in small batches in Tuscany, Italy, and pre-order only. The bicycle builds shown here is our factory spec option, but if you'd like to go custom we'll work with you to bring you your perfect bicycle.

This is our ultimate smooth, comfortable, fast, Multi-Terrain, Continent Crushing, Ultra Endurance machine! 

The BokehTi takes all the characteristics of our hugely popular, award and review winning Bokeh Alu and adds the incredibly taut, propulsive ride that is made possible by a full custom Italian tubeset made just for us by Dedacciai. 

This bike is designed for an engaging, spirited and dynamic ride across a hugely varied spectrum of surfaces and terrain. Take a look at our BokehTi gallery for an idea of how owners have specified their builds to exactly suit their riding styles or planned adventures.

GRX Di2 is Shimano's fully electronic adventure-riding specific groupset. Designed with a range of unique performance features and ergonomics developed over several years to make adventure riding as fast and comfortable as possible.

Our builds are available with 1×11 or 2×11 cranksets, both using adventure/bikepacking tuned ratios, and the latest clutched RX-817 Di2 derailleurs to match.

Please contact us for more details.

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. Because the BokehTi frames are built to order, we can take the ‘individual’ to a new level and give you the choice of a ‘standard’ build drawn from one of our Bokeh build levels such as the GRX Di2 build shown here, or choose to base your BokehTi build on your ideal specification. 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 HERE 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.

Details

Our frame sets deserve the best components, so we put a great deal of thought into the mix of parts used for each bike build. Bars, stem and crankset are sized to match frame size choice, but we can sometimes make sizing adjustments at your request.

If you would like to make it your own and dial-in the sizing or component choice for your dream build, go ahead and choose using the options in the 'Configure' option above.

Now available at your request are a range of HUNT wheelsets, a huge range of tyres and Ritchey VentureMax WCS Flare 'bars in all sizes. We're constantly improving our range of components to give you the ideal choice for bikepacking set-ups and precise off-road handling.

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, please choose your brake set-up in the Config. menu above the 'Order This Bike' button.

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.

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, 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 | BokehTi | Bokeh: 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.

MTB, TRAIL/TRAVEL - RAW: 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 is 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.
