Bokeh Ti GRX Di2

The exclusive Bokeh Ti frameset is welded in small batches in Tuscany, Italy, and pre-order only. The bicycle builds shown here are examples only, 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.

This page gives you some guidelines based on rider 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 and the rider size range is very similar for all our frames with 6 standard sizes [50-60cm]. InSearchOf sizing: 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.

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.
