InSearchOf Frameset

"..if you are looking to tackle more extreme off-road, while still having the ability to roll along comfortably on tarmac, or if you plan some serious bikepacking expeditions, it lets you go further and more extreme than just about any other drop bar bike."
 

This new bike is still firmly in the #FastFar, #ContinentCrushing vein but a progressive new frame and fork design allow it to use 29 x 2.4” or 650b x 2.8 wheels, meaning steeper, rougher and deeper terrain are well within it’s capabilities. Multiple mounting points, a bespoke load-bearing mudguard, specific rack systems, 160/180 flat-mount braking and 100mm suspension-ready geometry mean that the InSearchOf, once again, does not shy away from the ‘Progressive’ word in our title.

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.
